FMA1127DA
Touch Sensor Controller
Overview
The FMA1127DA is a low-power, compact, flexible touch sensor
controller that converts capacitance generated between the human
body and a conductive touch pad to digital data without any analog
signal processing.

Its programmability increases design flexibility and gives better
performance and stability for a broad range of applications.The
FMA1127DA’s Automatic Impedance Calibration (AIC™) function
can be easily configured to support different sensitivities for
individual channels independently as well as to change values of
parameters, such as calibration intervals. AIC may also be
temporarily paused and resumed by a host MCU.

Among the many new features of the FMA1127DA is Adjacent
Pattern Interference Suppression (APIS™). APIS is a filtering
function that eliminates adjacent key or pattern interference. The
FMA1127DA also gives touch-strength output in addition to touch
on/off output.There is a number of DIOs depending on the package
type that can be configured and programmed to meet a customer’s
specific needs, giving customers even greater flexibility and value.

Touch Sensor Controller
Operation Principles
Touch Detection
The FMA1127DA touch sensor controller includes the Impedance Change Detection engine within the device. It detects the impedance difference
between reference and sensor input.

Impedance Status
Figure 1: When a Pad is Not Touched.
Figure 2: When a Pad is Touched.
As shown in Figure 1, if the pad is not touched, the impedance of the sensor input Zin should be kept less than the impedance of the reference
Zref. If the pad is touched, as shown in Figure 2, Zin is increased by Ztouch. When Ztouch by touching becomes greater than the difference of Zin
and Zref in the not touched state, i.e., if Zin in touched state becomes greater than Zref by a value higher than 0.078pF, the ICD (Impedance
Change Detection) engine within the chip generates the acknowledged output signal indicating it senses the touch.
1, if Zin – Zref > 0.078pF
IDC =
0, otherwise
Notice the value of 0.078pF or higher is needed to maintain stable output against various noises. The sensor input impedance, Zin, includes
parasitic capacitance of the input line, tuning capacitance of input pin and on-chip input impedance, while Zref includes on-chip impedance, AIC
control values and external tuning capacitance if necessary.
AIC™ (Automatic Impedance Calibration)
Automatic Impedance Calibration (AIC) maintains consistent sensitivity against external environmental changes such as temperature, supply
voltage and current, humidity, and system-level variations. This helps users develop their applications more conveniently by providing the actual
impedance value of each sensor input. For developers, a Tuning Viewer program is provided, which helps to optimize the PCB design and to
decide AIC input parameters. More detailed information is available in the FM1127 Tuning Guide.
The ICD engine residing in the FMA1127DA controls reference impedance values for each sensor input pin by acquiring each input impedance
data. It periodically updates all reference impedance values under the condition that all twelve touch pads remain in no-touched status. This
auto-calibration function absorbs environmental changes and guarantees product stability.
APIS™ Touch Output
When touch pads are arranged too closely to each other, it is sometimes difficult to identify which pad is touched. APIS™ (Adjacent Pattern
Interference Suppression) is a filtering function to identify which pads are intentionally touched. If APIS mode is not defined, all touch data
without APIS filtering are transmitted to the MCU. For example, if the application is a numeric keypad, the user can use the APIS mode1 to get
the strongest output and filter out all other weakly touched inputs. Without APIS, the host may have to do this filtering function. APIS reduces
the burden of the host computing time.

There are three modes in APIS:
APIS mode 1: reports the strongest output only (Figure 3).
APIS mode 2: reports all outputs that exceeds pre-defined thresholds (value of Strength Threshold register) (Figure 4).
APIS mode 3: reports two strongest outputs (suitable for multi-touch applications) (Figure 5).
All three modes are described in the Figures below. The red-colored circles and bars show the output.

Note:
1. Devices that use non-standard supply voltages which do not conform to the intended I2C bus system levels must relate their input levels to the VDD voltage to which
the pull-up resistors Rp are connected.
2. Maximum VIH = VDDmax + 0.5V.
3. Cb = capacitance of one bus line in pF.
4. The maximum tf for the SDA and SCL bus lines quoted in Table 2 (300ns) is longer than the specified maximum tof for the output stages (250ns). The allows
series protection resistors (RS) to be connected between the SDA/SCL pins and the SDA/SCL bus lines as shown in Figure 6 without exceeding the maximum
specified for tf.
5. I/O pins of Fast-mode devices must not obstruct the SDA and SCL lines if VDD is switched off.
6. VIH = 1.21V, VIL = 0.76V. Hence Hysteresis is about 0.45V at the condition of 500kHz input frequncey. Input Impedance Cin is about 2pF.

Notes:
1. All values referred to VIHmin and VILmax levels (see Table 1).
2. A device must internally provide a hold time of al least 300ns for the SDA signal (referred to the VIHmin of the SCL signal) to bridge the undefined regions of the
falling edge of SCL.
3. The maximum tHD:DAT has only to be met if the device does not stretch the LOW period (tLOW) of the SCL signal.
4. A Fast-mode I2C-bus device can be used in a Standard-mode I2C-bus system, but the requirement tSU:DAT Š 250ns must then be met. This will automatically be the
case if the device does not stretch the LOW period of the SCL signal. If such a device does stretch the LOW period of the SCL signal, it must output the next data bit
to the SDA line tmax + tSU:DAT = 1,000 + 250 = 1,250ns (according to the Standard-mode I2C bus specification) before the SCL line is released.
5. Cb = total capacitance of one bus line in pF. If mixed with Hs-mode devices, faster fall-times according the Table 2 are allowed.

(LED Control Circuit)
Notes:
• The voltage range of VDD can be from 2.3V to 5.5V. If internal LDO is used, it should be from 3V to 5.5V.
• Pull-Up resistors are required for I2C communication. For 5V application, 2K ohm resistor is typically used. For 3V application, 1K
ohm resistor is typically used.
• Each tuning capacitor is an optional component depending on PCB layout environment.
• The circuit above is a typical application circuit using an internal LDO.
• RESET_N pin should be connected to host MCU GPIO and needs an RC filter. (R1=10KΩ, C1=1uF)
• For LED control through DIO ports, sink current circuit is mandatory as shown above.
• I2C has no recovery specification when clk is attacked by noise glitch or ESD. Sometimes ‘additional’ clock by noise glitch generates
unintentional START condition which causes the TSC to wait indefinitely.
Recommendations to avoid such a noise glitch:
2
1. Addition of serial resister on I C clock line and data line having values ranging from 100ohm to 500ohm.
2
2. Addition of about capacitor on I C clock line and data line and connect other end to ground. This would add some filtering mechanism. The size
of capacitor depends on existing parasitic capacitance of the board (~Value ranging from 30pf to 300pf).

FMA1127DA
Power Connection
There are two methods to supply power to the FMA1127DA touch sensor controller. One is to receive V25 core voltage from internal LDO and
the other is to receive core voltage from an external power supply. In the case of using internal LDO, the LDO should be turned on in Sleep mode
and hence it will cause slightly higher power consumption than using an external power supply for V25 core voltage.
In Case E, if VPH receives 2.5V, internal LDO can not be used because VLDO can not output 2.5V when VPH receives 2.5V from external LDO.

Power Sequence
To initialize the ATA2508DA properly, please refer to the Power Sequence below when the power is given initially during boot-up.
If the reset transition time during power on does not follow the time sequence below, the Internal LDO and oscillator would not operate
normally.
The Power Sequence is based on the Power Connection type and is shown in the following example.
Power Connection Type is Case B or Case D
VDDH(3.3V or 5.5V) X 0.9
VDDH(IO)
RESET PERIOD
GND + 0.3V
RESET_N
Min 0.1 msec
Fixed “L”
Power Connection type is Case A, Case C, or Case E
VDDH(2.5V or 3.3V or 5.5V) X 0.9
VDDH(IO)
V25(2.5V) X 0.9
V25(Core)
RESET PERIOD
GND + 0.3V
RESET_N
Min 0.1 msec
Fixed “L”
In order to delay RESET_N transition about 0.1msec than VDDH transition, 10KO resistor and 1uF capacitor should be attached on
RESET_N pin. Please see the typical application circuits described in the previous chapter. Also note that pulse width of RESET_N which is
active low and generated by MCU must be longer than 0.1msec to be valid RESET signal.
