1 Hardware Description

1.1 Pin Description

Table 1: 73S1215F Pinout Description

Pin Name

Description

X12IN

Figure 27 MPU/USB clock crystal oscillator input pin. A 12MHz

crystal is required for USB operation. A 1MΩ resistor

is required between pins X12IN and X12OUT.

X12OUT

X32IN

Figure 27 MPU/USB clock crystal oscillator output pin.

Figure 28 RTC clock crystal oscillator input pin. A 32768Hz

crystal is required for low-power RTC operation.

X32OUT

CPUCLK

Figure 28 RTC clock crystal oscillator output pin.

Figure 30 Output signal, square wave at the frequency of the

MPU clock.

Figure 43 USB D+ IO pin, requires series 24Ω resistor.

Figure 43 USB D- IO pin, requires series 24Ω resistor.

Figure 34 Keypad row input sense.

ROW(5:0)

COL(4:0)

Keypad column output scan pins.

Figure 35

Figure 31

USR(8:0)

General-purpose user pins, individually configurable as

inputs or outputs or as external input interrupt ports.

SCL

Figure 30 I²C (master mode) compatible Clock signal. Note: the

pin is configured as an open drain output. When the

I2C interface is being used, an external pull up resistor

is required. A value of 3K is recommended.

SDA

Figure 29 I²C (master mode) compatible data I/O. Note: this pin is

bi-directional. When the pin is configured as output, it

is an open drain output. When the I2C interface is

being used, an external pull up resistor is required. A

value of 3K is recommended.
