Type Circuit Description
O
5
LCD Common Outputs: These 4 pins provide the select signals for the
LCD display.
O
5
Dedicated LCD Segment Output pins.
Multi-use pins, configurable as either LCD SEG driver or DIO (DIO4 =
O
3, 4, 5
SCK, DIO5 = SDA when configured as EEPROM interface, WPULSE
= DIO6, VARPULSE = DIO7 when configured as pulse outputs). If
unused, these pins must be configured as outputs.
O
4, 5
Multi-use-pin LCD Segment Output/ MUX_SYNC is output for
Synchronous serial interface
Multi-use-pin, LCD Segment Outputs/ SRDY input for Synchronous
I/O
2, 5 serial interface. When configured as SRDY, this pin must be pulled
down to GNDD.
O
4, 5
Multi-use-pin, LCD Segment Output/ SFR output for Synchronous
serial interface.
O
4, 5
Multi-use-pin, LCD Segment Output/ SDATA output for Synchronous
serial interface.
O
4, 5
Multi-use-pin, LCD Segment Output/ SCLK output for Synchronous
serial interface.
O
4
Clock PLL output. Can be enabled and disabled by CKOUT_DIS.
O
4
Digital output test multiplexer. Controlled by DMUX[3:0].
Optical Receive Input: This pin may receive a signal from an external
I
7
photo-detector used in an IR serial interface. If this pin is unused it
must be terminated to V3P3D or GNDD.
Optical LED Transmit Output: This pin is designed to directly drive an
O
4
LED for transmitting data in an IR serial interface. Can be tristated with
OPT_TXDIS to be multiplexed with other DIO pins.
This input pin resets 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
I
1
has an internal 30µA (nominal) current source pull up. A 0.1µF ca-
pacitor to GNDD should be connected to this pin. See the precau-
tions in the Applications Section for terminating this pin.
I
3
UART input. The voltage applied at this input must be below 3.6V.
If this pin is unused it must be terminated to V3P3D or GNDD.
O
4
UART output.
I/O
1, 4 Emulator serial data. This pin has an internal pull-up resistor.
O
4
Emulator clock.
I/O
1, 4
Emulator reset. This pin has an internal pull-up resistor. See the
precautions in the Applications Section for terminating this pin.
I
7
Enables Production Test. This pin must be grounded in normal
operation.
Pin types: P = Power, O = Output, I = Input, I/O = Input/Output
