Table 2.2.4 Pin Names and Functions (4/4)

Pin Names

Number

of Pins

I/O

Functions

AM8/ AM16

Input Address mode: Selects external data bus width.

(On the TMP93CS40)

The Vcc pin should be connected. The data bus width for external

access is set by the chip select/WAIT control register, port 1 control

(On the TMP93CS41)

The Vss pin should be connected to access either fixed 16-bit bus

width, or 16-bit bus interchangeable with 8-bit bus.

The Vcc pin should be connected to access a fixed 8-bit bus width.

ALE

Output Address latch enable

(Can be disabled to reduce noise.)

RESET

Input Reset: Initializes TMP93CS40/TMP93CS41. (with pull-up resistor)

X1/X2

I/O High-frequency oscillator connecting pin

P96

XT1

I/O

Input

Port 96: I/O port (open-drain output)

Low-frequency oscillator connecting pin

P97

XT2

I/O

Output

Port 97: I/O port (open drain output)

Low-frequency oscillator connecting pin

TEST1/TEST2

Output/Input TEST1 pin should be connected to TEST2 pin.

Don’t connect to any other pins.

VCC

Power supply pin (All VCC pins should be connected to the power supply pin.)

VSS

GND pin (0 V) (All VSS pins should be connected to GND (0 V).)

AVCC

Power supply pin for AD converter

AVSS

GND pin for AD converter (0 V)

Note: All pins that have built-in pull-up/pull-down resistors (other than the RESET pin) can be

disconnected from the built-in pull-up/pull-down resistor by software.
