Notes: 1. t DF is defined as the time at which the outputs achieve the open circuit conditions and are no longer driven. 2. Use this device in longer cycle than this value. 3. t WC must be longer than this value unless polling techniques or RDY/Busy are used. This device automatically completes the internal write operation within this value. 4. Next read or write operation can be initiated after tDW if polling techniques or RDY/Busy are used. 5. A6 through A12 are page addresses and these addresses are latched at the first falling edge of WE. 6. A6 through A12 are page addresses and these addresses are latched at the first falling edge of CE. 7. See AC read characteristics.

Toggle Bit This device provide another function to determine the internal programming cycle. If the EEPROM is set to read mode during the internal programming cycle, I/O6 will charge from "1" to "0" (toggling) for each read. When the internal programming cycle is finished, toggling of I/O6 will stop and the device can be accessible for next read or program. Toggle Bit Waveform Notes: 1. 2. 3. 4. I/O6 beginning state is "1". I/O6 ending state will vary. See AC read characteristics. Any address location can be used, but the address must be fixed.

Functional Description
Automatic Page Write Page-mode write feature allows 1 to 64 bytes of data to be written into the EEPROM in a single write cycle. Following the initial byte cycle, an additional 1 to 63 bytes can be written in the same manner. Each additional byte load cycle must be started within 30 s from the preceding falling edge of WE or CE. When CE or W E is kept high for 100 s after data input, the EEPROM enters write mode automatically and the input data are written into the EEPROM. Data Polling Data polling indicates the status that the EEPROM is in a write cycle or not. If EEPROM is set to read mode during a write cycle, an inversion of the last byte of data outputs from I/O7 to indicate that the EEPROM is performing a write operation. RDY/Busy Signal RDY/B usy signal also allows status of the EEPROM to be determined. The RDY/Busy signal has high impedance except in write cycle and is lowered to VOL after the first write signal. At the end of a write cycle, the RDY/Busy signal changes state to high impedance. WE, CE Pin Operation During a write cycle, addresses are latched by the falling edge of WE or CE, and data is latched by the rising edge of WE or CE. Write/Erase Endurance and Data Retention Time The endurance is 10 5 cycles in case of the page programming and 104 cycles in case of the byte programming (1% cumulative failure rate). The data retention time is more than 10 years when a device is page-programmed less than 104 cycles.

Data Protection 1. Data Protection against Noise on Control Pins (CE, OE, WE) during Operation During readout or standby, noise on the control pins may act as a trigger and turn the EEPROM to programming mode by mistake. To prevent this phenomenon, this device has a noise cancellation function that cuts noise if its width is 15 ns or less. Be careful not to allow noise of a width of more than 15 ns on the control pins.

VIH 0V
OE

15 ns max
2. Data protection at VCC on/off When V CC is turned on or off, noise on the control pins generated by external circuits (CPU, etc) may act as a trigger and turn the EEPROM to program mode by mistake. To prevent this unintentional programming, the EEPROM must be kept in an unprogrammable state while the CPU is in an unstable state. Note: The EEPROM should be kept in unprogrammable state during V CC on/off by using CPU RESET signal.
VCC CPU RESET * Unprogrammable
* Unprogrammable
HN58S65A Series
(1) Protection by CE, OE, WE To realize the unprogrammable state, the input level of control pins must be held as shown in the table below.
CE OE WE x: Don't care. VCC: Pull-up to VCC level. VSS : Pull-down to V SS level. VCC x x x VSS x x x VCC
3. Software data protection To prevent unintentional programming caused by noise generated by external circuits, this device has the software data protection function. In software data protection mode, 3 bytes of data must be input before write data as follows. And these bytes can switch the non-protection mode to the protection mode. SDP is enabled if onry the 3 byte code is input.

1555 AA 0AAA 55 1555 A0 Write address Write data } Normal data input
Software data protection mode can be canceled by inputting the following 6 bytes. After that, this device turns to the non-protection mode and can write data normally. But when the data is input in the canceling cycle, the data cannot be written.

The software data protection is not enabled at the shipment. Note: There are some differences between Hitachi's and other company's for enable/disable sequence of software data protection. If there are any questions , please contact with Hitachi sales offices.
