General Description
The BS801B/02B/04B/06B/08B are a range of 1 to 8 key touch key devices which can detect human body contact using external touch pads. The high level of device integration enable applications to be implemented with a minimum number of external components. The BS804B and BS808B are equipped with a One-line serial interface to allow easy communication with an external MCU for device setup and for touch pin monitoring purposes.

Functional Description
Introduction This range of BS80xB touch key devices offer an easy and reliable means of implementing touch switch functions in a range of applications. A single external capacitor is the only external component required for most applications while a single line serial bus offers convenient communication with an external MCU. Device Operation Modes All devices have two modes of operation, the Standby Mode and the Normal Mode. After the device is powered up it will automatically enter the Standby Mode to conserve power. The BS801B and BS802B devices can then be woken up by touching any of their Keyn pins. The BS804B, BS806B and BS808B devices can however be woken up by either a One-key Wake-up using Key0, or by Any-key Wake-up. The wake-up method is determined by the status of the OKW pin which is read only during power-on. The advantage of choosing the One-key wake-up option is that it consumes less power than the Any-key wake-up when in the Standby Mode.

The logic status of the OKW pin is read when the device powers up. The logic level on this pin must not be changed after power on.

When in the Standby Mode, after a relevant Keyn wake-up detection has been made, the device will switch to the Normal Mode and await subsequent switch detections on all their Keyn pins. It will remain in the Normal Mode for about 10 seconds for the BS801B and BS802B devices and for about 20 seconds for the other devices and if no further detections are made during this time will return to the Standby Mode.

Touch Key Outputs All Kout pins have NMOS structures to allow easy interfacing to external devices with different operating voltages. The BS801B, BS802 and BS804B devices can have their outputs configured to operate with either Level-Hold or Toggle type. The output type is determined by the status of the LHF pin which is read during power-on. The logic level on this pin must not be changed after power on. Internal circuitry ensures that the internal pull-high resistor on the LHF pin will not consume current. The BS806B and BS808B only have Level-Hold output types.

SCD Function Summary
* BS804B/BS808B Wakes-up or Interrupts MCU
When any of the touch keys change state, a pulse will be generated by the BS804B/BS808B device which can be used to wake up or to interrupt an external MCU. The MCU must ensure that its pin connected to the SCD pin is setup as an input to receive this pulse. The pulse width generated by the device is equal to a tSCD/2 period where tSCD is about 76ms.

* MCU reads the touch key status
The MCU can send a command to the BS804B/ BS808B device to request the touch key status. The protocol for reading the touch key status is as follows:
The MCU can send commands along the SCD line to setup the device in different Operating Modes. To do this the externally connected MCU takes control of the SCD line, first forcing it low and holding it low for a time of greater than 8 tSCD cycles. This action will temporarily disable the device and enable it to receive the command from the MCU. Any command sent to the device from the MCU will override the original power on configuration setup.

The external MCU takes control of the SCD line and first sends three rising edge pulses or more to the BS804B/BS808B within a time of about 152ms. The MCU then changes its I/O pin to an input. The BS804B/BS808B device will then pull the SCD line low, then high, the timings are given by synchronise period. This allows the MCU to synchronise itself for the data transfer. The BS804B/BS808B device will then transmit its key status, given by D0~Dn

SCD Device Setup The desired Operating Mode to be setup depends upon the number of pulses received by BS804B/ BS808B within a time period, 4 tSCD, as shown in the table. After the programming clock cycles have been transmitted and the SCD line returns high, the device will return to normal operation. Clock Pulses 0~2 3~6 7~10 11~14 >15 Operating Mode Set by external pin One-key wake-up For test purposes Any-Key wake-up Always normal operation BS804B and BS808B SCD Commands
For the BS804B, the data format is D0~D3. For the BS808B, the data format is D0~D7.
The MCU can then read the key status taking care to read the data in the centre of the transmitted data pulse. Af t e r t he l as t dat a b i t i s t r a n s f er r e d t h e BS804B/BS808B device will return its SCD pin to an input state.
The timings associated with the above protocol can be described in multiples of the SCD clock periods. The SCD clock period is about about 76ms. A certain time is required for the MCU to transmit three or more pulses to inform the device that it desires to Rev. 1.00 7

SCD Pin Touch Key Status Request
Note that the MCU must transmits these pulses within 4 tSCD. Maximum Key On Duration Time To minimise the possibility of unintentional switch detections, such as undesired objects covering the sense electrodes, the devices includes a Maximum Key-On duration time function. To implement this function the devices include an internal timer, which starts running after each switch detection. If the key on time of a touch key exceeds a value of about 40 seconds, then the device will be reset to its power-on condition and initiate a new auto calibration. The output will then remain inactive until the next switch detection. Auto-calibration Function The devices include a full auto-calibration function which will be initiated after the device is powered-on. In addition to the power-on calibration, if no switch detection has been made for more than about 2.5 seconds then a further calibration procedure will be carried out. The calibration is applied independently to each channel on the devices. By implementing this feature, changes in the touch key environmental conditions are automatically catered for dynamically.
An external capacitor, Cs, connected to the Cref pin, is used to set the overall sensitivity of all pins. Some of the most important factors affecting sensitivity are the following:
* Cref capacitor value - Cs
The purpose of the Cs capacitor is to allow for adjustment of touch key sensitivity and power noise rejection. The optimal choice of sensitivity and power noise rejection will be obtained when the value of the Cs capacitor is equivalent to the touch pad capacitance, however the value can still be changed to obtain the required sensitivity value. Higher Cs values will result in higher levels of sensitivity. Recommended values for Cs are between 0pF and 10pF.
* Touch key pad size
Larger touch key sizes will increase sensitivity and of course vice-versa, small electrode sizes will decrease sensitivity.
* Touch key pad insulating panel thickness
A thinner panel will result in higher sensitivity and of course thicker panels will result in a lower sensitivities.
* Touch key pad insulating panel material
The choice of the dielectric material for the panel will influence the sensitivity. Materials with higher dielectric constants will result in higher sensitivities and lower dielectric constants will result in lower sensitivities.
Sensitivity Adjustment
The sensitivity of the switch is a very important consideration in most applications whose requirements will vary according to the user application. The user should therefore be aware of the factors which will affect the overall sensitivity of their touch key application. Factors to take into consideration include the electrode size and the capacitance of the connection lines from the electrode to the BS80xB device. Therefore the sensitivity will vary according to the actual PCB layout and design.
