General Description
The BS801C/02C/04C/06C/08C 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 de-
vice 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 applica-
tion reliability under adverse environmental conditions.
With auto-calibration, low operating current and a low
power one-key operating state, this range of touch key
devices provides a simple and effective means of imple-
menting touch switches in a wide variety of applications.
The BS804C and BS808C are equipped with a One-line
serial interface to allow easy communication with an exter-
nal MCU for device setup and for touch pin monitoring pur-
poses.

Functional Description
Introduction
actions are detected on any Key input, then the device
will revert to the One-key State.
This range of BS80xC touch key devices offer an easy
and reliable means of implementing touch switch func-
tions in a range of applications. A single external capaci-
tor is the only external component required for most
applications while a single line serial bus offers conve-
nient communication with an external MCU.
The advantage of choosing the One-key State over the
Any-key State is that it will result in lower power con-
sumption as only one key remains active. The logic sta-
tus of the OKW pin is only read when the device powers
up and will determine the operating state of the device
after power-on. For the BS804C and BS808C devices,
this power-on state can be overridden later by sending
the appropriate command to the device on its SCD pin.
The logic level on the OKW pin must not be changed af-
ter power on. Internal circuitry ensures that the internal
pull-high resistor on the OKW pin will not consume cur-
rent after power-on.
Device Operation State
There are two operating states known as the One-key
State and the Any-key State. Devices with an OKW pin,
namely the BS804C, BS806C and BS808C, can oper-
ate in either the One-key State or the Any-key State.
When these devices are powered up, the condition of
the OKW pin will be automatically read. If the OKW pin is
low then the device will enter the Any-key State and if
the pin is floating the device will enter the One-key
State. As the BS801C and BS802C devices do not have
an OKW pin they will always operate in the Any-key
State.

The logic status of the OKW pin is read when the device

the internal pull-high resistor on the OKW pin will not
consume current.
In the Any-key State, as the name suggests all of the
Keyn touch inputs will be active, however in the One-key
State only Key0 will be active. After power up if the
BS804C, BS806C and BS808C device enters the
One-key State then touching any Key other than Key0
will have no effect. If a touch action is however detected
on Key0, then the device will enter the Any-key State
and operate normally with all keys active. However,
within a timer period of around 20 seconds, if no touch

lows three functions to be implemented, two are initiated
by the external MCU and one by the BS80xC.
All Kout pins have NMOS structures to allow easy inter-
facing to external devices with different operating volt-
ages. The BS801C, BS802 and BS804C devices can
have their outputs configured to operate with either
Level-Hold or Toggle type. The output type is deter-
mined 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 BS806C and BS808C only have
Level-Hold output types.

When any of the touch keys change state, a pulse will
be generated by the BS804C/BS808C 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.

MCU reads the touch key status
command from the MCU. Any command sent to the
device from the MCU will override the original power
on configuration setup.
The MCU can send a command to the BS804C/
BS808C device to request the touch key status. The
protocol for reading the touch key status is as follows:

line low, then high, the timings are given by syn-

SCD Device Setup
¨
The BS804C/BS808C device will then transmit its
key status, given by D0~Dn
The desired Operating Mode to be setup depends
upon the number of pulses received by BS804C/
BS808C 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.
-
For the BS804C, the data format is D0~D3.
-
For the BS808C, 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.

A certain time is required for the MCU to transmit three

read the key status. After this time has elapsed the de-
vice will then transmit the data bits, D0~Dn.

To minimise the possibility of unintentional switch detec-
tions, 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 de-
vice will be reset to its power-on condition and initiate a
new auto calibration. The output will then remain inac-
tive until the next switch detection.
Key Status Read Total Time
Each bit of transmitted data corresponds directly to a
touch input key. Therefore the status of touch key Key0
is represented by D0, Key1 by D1 and so on. A ²low² bit
means that a touch has been detected, a ²high² bit
means no touch has been detected.

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 detec-
tion 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 chan-
nel on the devices. By implementing this feature,
changes in the touch key environmental conditions are
automatically catered for dynamically.

MCU sends commands to BS804C/BS808C device
The MCU can send commands along the SCD line to
setup the device in different Operating State. 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 tem-
porarily disable the device and enable it to receive the

SCD Pin Touch Key Status Request
Sensitivity Adjustment
·
The sensitivity of the switch is a very important consider-
ation 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 elec-
trode to the BS80xC device. Therefore the sensitivity
will vary according to the actual PCB layout and design.
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 fol-
lowing:
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 in-
fluence the sensitivity. Materials with higher dielectric
constants will result in higher sensitivities and lower di-
electric constants will result in lower sensitivities.

·
Cref capacitor value - Cs
Key
The purpose of the Cs capacitor is to allow for adjust-
ment of touch key sensitivity and power noise rejec-
tion. The optimal choice of sensitivity and power noise
rejection will be obtained when the value of the Cs ca-
pacitor 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.
