isd1100 series - 6 - 6. pin description pin name pin no. function a0-a7 1-6, 9, 10 address inputs : the address inputs have two functions, depending on the level of the two most significant bits (msb) of the address (a6 and a7). if either or both of the two msbs are low, all inputs are interpreted as address bits and are used as the start address for the current record or play back cycle. the address pins are inputs only and do not output internal address information as the operation progresses. addr ess inputs are latched by the falling edge of playe , playl , or rec . if both a6 & a7 are high, then the device is in a special operational mode for looping. please refer to looping capability section for details. a0, a1, a2, a3, a4 and a5 have internal pull-down resistors, while a6 and a7 have internal pull-up resistors. they can be floating if not used. each of these internal pull-up or pull-down devices have a value of 50 k ? to 100 k ? . v ssa , v ssd 12, 13 ground : similar to v cca and v ccd , separate analog and digital ground rails provide independent analog and digital ground buses internally to minimize noise. these pins should be tied together as close as possible to the device. sp+, sp- 14, 15 speaker outputs : the differential sp+ and sp- pins are designed to drive a 16 ? speaker directly. conversely, with single-ended connection, a coupling capacitor is needed between the sp pin and the speaker. besides, the output power is about a quarter of that from differential output. the speaker outputs are in high-impedance state during recording and at v ssa during power down. v cca , v ccd 16, 28 supply voltages : separate analog and digital powers provide power to internal analog and digital circuits respectively to minimize internal noises. these power buses are brought out to separate pads and should be tied together as close to the supply source as possible. it is important that the power supplies are decoupled as close to the device as possible. mic 17 microphone : the microphone input transfers its signal to the on-chip preamplifier. an on-chip automatic gain control (agc) circuit controls the gain of this preamplifier from ?15 to 24db. an external microphone should be ac coupled to this pin via a series capacitor. the capacitor value, together with the internal 10 k ? resistance on this pin, determines the low- frequency cutoff for the device passband. see winbond?s application information for additional information on low- frequency cutoff calculation.
isd1100 series publication release date: april 25, 2006 - 7 - revision 1.2 pin name pin no. function mic ref 18 microphone reference : the mic ref input is the inverting input to the microphone preamplifier. this provides a noise- canceling or common-mode rejection input to the device when connected to a differential microphone. agc 19 automatic gain control (agc) : the agc input dynamically adjusts the gain of the preamplif ier to compensate for the wide range of microphone input levels. the agc allows the full range of sound, from whispers to loud sounds, to be recorded with minimal distortion. the ?attack? time is determined by the time constant of a 5 k ? internal resistance and an external capacitor (c6 of figure 5 in section 11) connected from the agc pin to v ssa . the ?release? time is determined by the time constant of an external resistor (r5) and an external capacitor (c6) connected in parallel between the agc pin and v ssa pin. nominal values of 470 k ? and 4.7 f give satisfactory results in most cases. tying this to ground gives maximum gain, while tying it to v cca gives minimum gain for the agc amplifier. ana in 20 analog input : the ana in transfers an input signal to the chip for recording. for microphone usage, this ana in pin should be connected via an external capacitor to the ana out pin. this capacitor value, together with the 3 k ? input impedance of ana in, is selected to give additional cutoff at the low-frequency end of the voice passband. if the desired input is derived from a source other than a microphone, the signal can be capacitively coupled into the ana in pin directly. ana out 21 analog output : this pin provides the preamplifier output to the user. the voltage gain of the preamplifier is determined by the voltage level at the agc pin. playl [2][3] 23 playback, level-activated : when this input signal is held low, a playback cycle is init iated, and playback continues until playl is pulled high, or an eom marker is detected. the device automatically powers down and enters into standby mode upon completion of a playback cycle. this pin has an internal pull-up resistor. playe [2][3] 24 playback, edge-activated : when a low-going transition is detected on this pin, a playback cycle begins. taking playe high during a playback cycle w ill not terminate the current cycle. playback continues until an eom is encountered. upon completion of a playback cycl e, the device automatically powers down and enters into standby mode. this pin has an internal pull-up device.
isd1100 series - 8 - pin name pin no. function recled 25 record led : the recled output is low during a record cycle. it can be used to drive an led to indicate a record cycle is in progress. in addition, recled pulses low momentarily when an end-of-message is encountered in a playback operation. xclk 26 external clock : the external clock input has an internal pull- down resistor. the isd1100 is configured at the factory with an internal sampling clock frequency that guarantees its minimum nominal record/playback time. for instance, an isd1110 operating within specification will be observed to always have a minimum of 10 seconds of recording time. the sampling frequency is then maintained to a variation of 2.25 percent over the commercial temperature and operating voltage ranges while still maintaining the minimum duration specified. as a result some devices will have a few percent more than nominal recording time. if greater precision is required, the device can be clocked through the xclk pin as follows: external clock sample rates part number sample rate required clock isd1110 6.4 khz 819.2 khz isd1112 5.3 khz 682.7 khz these recommended clock rates should not be varied because the anti-aliasing and smoothing filters are fixed, and aliasing problems can occur if the sample rate differs from the one recommended. the duty cycle on the input clock is not critical, as the clock is immediately divided by two. if the xclk is not used, this pin must be grounded. please see application information for the isd1100 series for more details on external clocking.
isd1100 series publication release date: april 25, 2006 - 9 - revision 1.2 pin name pin no. function rec [1][3] 27 record : the rec input is an active-low signal. the device records whenever rec is low. this signal must remain low for the duration of the recording. a record cycle is completed when rec is pulled high or the memory space is filled up. rec takes precedence over either playback ( playe or playl ) signal. if rec is pulled low during a playback cycle, the playback immediately ceases and recording begins. an end-of-message (eom) marker is internally recorded, enabling a subsequent playback cycle to terminate appropriately. the device automatically powers down into standby mode when rec goes high. this pin has an internal pull-up resistor. nc 11 nc : no connect notes: [1] the rec signal is debounced for 50 ms on the rising edge to prevent a false retriggering from a push- button switch. [2] during playback, if either playe or playl is held low during eom or ovf, the device will still enter into standby mode and the internal oscillator and timing generator will stop. however, the rising edge of playe and playl are not debounced and any subsequent falling edge (particularly switch bounce) present on the input pins will initiate another playback. [3] rec , playl and playe have internal pull-ups to v cc . holding on these pins low wil increase standby current consumption.
isd1100 series - 10 - 7. functional description 7.1. d etailed d escription speech/sound quality winbond?s patented chipcorder ? technology provides natural audio record and playback. the isd1100 series include devices of 5.3 khz and 6. 4 khz sampling frequencies, allowing the user a choice of speech quality options. the input voice si gnals are stored directly into non-volatile eeprom cells and are reproduced without the synthetic effe ct often heard with digital solid-state speech solutions. a complete sample is stored in a single cell, minimizing the memory necessary to store a recording of a given duration. duration the isd1100 series offer single-chip solutions of 10 and 12 seconds duration. table 1: isd1100 series product summary part number duration (seconds) input sample rate (khz) typical filter pass band* (khz) isd1110 10 6.4 2.6 isd1112 12 5.3 2.2 * 3db roll-off-point?. eeprom storage one of the benefits of winbond?s chipcorder ? technology is the use of on-chip non-volatile memory, providing zero-power message storage. the message is retained for up to 100 years typically without power. in addition, the device can be re -recorded typically over 100,000 times. basic operation the isd1100 chipcorder ? series are controlled by a single signal, rec , or one of two playback control signals, playe (edge-activated playback), and playl (level-activated playback). the isd1100 series parts are configured for simplicity of design in a single/multiple-message application. using the address lines will allow multiple message applications. automatic power-down mode at the end of a playback or record operation, the isd1100 series automatica lly enters into a standby mode, with typically 0.5 a current. during a play back cycle, the device power s down automatically at the end of the message. during a record cycl e, the device powers down immediately after rec is released high.
isd1100 series publication release date: april 25, 2006 - 11 - revision 1.2 addressing in addition to single-message application, the isd 1100 series provides a full addressing capability for multiple message application. the memory array of isd1100 series has 80 di stinct addressable rows, providing the below resolutions per row. see application inform ation for address tables of isd1100 series. table 2: device playback/record durations part number minimum duration (per row) isd1110 125 msec isd1112 150 msec looping capability the isd1100 series device has a built-in looping f unction enabling it to continuously repeat a single message. this mode is accomplished by taking a3, a6 and a7 pins high simultaneously to continuously loop from the end of the message to the beginning of the message. looping is initiated by a negative transition on playe pin with a3, a6 and a7 held high, then playe is brought back to high. looping will continue indefinitely with all three control pins ( playe , playl , rec ) remaining high, until playl is pulsed to low, which ends the looping.

isd1100 series - 24 - functional description example the following operating sequence example demonstrat es the functionality of the isd1100 series. 1. record a message: pulling the rec signal low initiates a record cycle from current location. when rec is held low, the recording continues. until the memory array is filled up or when rec is pulled high, recording ceases. an eom marker is written at the end of message. then the device will automatically power down. 2. edge-activated playback: pulling the playe signal low initiates a playback cy cle from the beginning of the message until the entire message is played. the rising edge of playe has no effect on operation. when the eom marker is encountered, the dev ice automatically powers down. a subsequent falling edge on playe initiates a new playback operation from the beginning of the message. 3. level-activated playback: holding the playl signal low initiates a playback cycle from the beginning of the message, until playl is pulled high or when the eom marker is encountered, playback operation stops and the device automatically powers down. 4. record (interrupting playback). the rec signal takes precedence over playback operation. holding rec low initiates a new record operation from current location, r egardless of any current operation in progress. 5. recled operation. during record, the recled output pin provides an active-low signal, which can be used to drive an led as a ?record-in-progress? indica tor. it returns to a high state when the rec pin is pulled high or when the recording is completed due to the memory being filled. however, during playback, this pin also pulses low to indicate an eom at the end of a message.
isd1100 series publication release date: april 25, 2006 - 25 - revision 1.2 applications note some users may experience an unexpected recording taking place when their circuit is powered up, or the batteries are changed, and v cc rises faster than rec . this undesired recording prevents playback of the previously recorded message. a spurious eom marker appears at the very beginning of the memory, preventing access to the original message, and nothing is played. to prevent this occurrence, install a capacitor (approx. 0.001 f) between the rec and v cc pins. this pulls the control pin voltage up with v cc as it rises. once the voltage is high, the pull-up device will keep the pin high until intentionally pu lled low, preventing the false eom marker. since this condition is dependent upon factors such as the capacitance of the user?s printed circuit board, not all circuit designs will exhibit the spur ious marker. it is recommended, however, that the capacitor is included for design reliability. a more detailed explanation and resolution of this occurrence is described in application information.
