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.
Special internal circuitry is also employed to ensure
excellent power noise rejection to reduce the possibility
of false detections, increasing the touch switch application reliability under adverse environmental conditions.
With auto-calibration, low standby current and a choice
of wake-up features, this range of touch key devices
provides a simple and effective means of implementing
touch switches in a wide variety of applications.
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.

Wake-up
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. Internal circuitry ensures that
the internal pull-high resistor on the OKW pin will not
consume current.
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.

Touch Key Outputs
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.
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.

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

The external MCU takes control of the SCD line and
first sends three rising edge pulses or more to the

The MCU then changes its I/O pin to an input.

The BS804B/BS808B device will then pull the SCD

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.
The BS804B/BS808B device will then transmit its
key status, given by D0~Dn
The MCU can then read the key status taking care
to read the data in the centre of the transmitted data
pulse.

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

Each bit of transmitted data corresponds directly to a

SCD Pin Touch Key Status Request
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:
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.
· 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.
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.
· 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
Touch
Key
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.
