Description
Digital input/output pins 0 through 3. If unused, these DIO pins must be
configured as outputs or terminated to V3P3 or ground.
LCD Common Outputs: These 4 pins provide the select signals for the
LCD display.
Dedicated LCD Segment Output.
Multi-use pins, configurable as either LCD SEG driver or DIO (DIO4 =
SCK, DIO5 = SDA when configured as EEPROM I/F, WPULSE = DIO6,
VARPULSE = DIO7 when configured as pulse outputs). If unused, these
pins must be configured as outputs or terminated to V3P3/ground.
Multi-use-pin LCD Segment Output/ MUX_SYNC is output for Synchron-
ous serial interface
Multi-use-pin, LCD Segment Outputs/ SRDY input for Synchronous serial
interface. If unused, this pin must be terminated to ground.
Multi-use-pin, LCD Segment Output/ SFR output for SSI.
Multi-use-pin, LCD Segment Output/ SDATA output for SSI.
Multi-use-pin, LCD Segment Output/ SCLK output for SSI.
This pin is used to reset the chip into a known state. For normal operation,
this pin is set to 1. To reset the chip, this pin is driven to 0. This pin has an
internal 30μA (nominal) current source pull-up but no Schmitt-trigger
circuitry. The minimum width of the pulse is 5μs. A 0.1µF capacitor to
GNDA should be connected to this pin. Since the chip resets itself at
power-up, no other external reset circuitry is required.
UART input. The voltage applied at this input must be below 3.6V. If un-
used, the RX pin must be terminated to V3P3 or ground.
UART output.
Optical Receive Input: This pin receives a signal from an external photo-
detector used in an IR serial interface. If unused, the OPT_RX pin must
be terminated to V3P3 or ground.
Optical LED Transmit Output: This pin is designed to directly drive an LED
for transmitting data in an IR serial interface. Can be tristated with
OPT_TXDIS to be multiplexed with other DIO pins.
Clock PLL output. Can be enabled and disabled by CKOUT_EN.
Digital output test multiplexer. Controlled by TMUX[3:0].
Emulator serial data.
Emulator trace bus. These pins have internal pull-up resistors.
Emulator handshake. This pin has an internal pull-up resistor.
Emulator clock. This pin has an internal pull-up resistor.
Emulator reset. This pin has an internal pull-up resistor.
For Teridian internal use. Must be connected to GNDD via a 10kΩ resistor.
