73S1215F Data Sheet

Pin Name

Description

LED(3:0)

Figure 36 Special output drivers, programmable pull-down

current to drive LEDs. May also be used as inputs.

RXD

Figure 33 Serial UART Receive data pin.

Figure 30 Serial UART Transmit data pin.

Figure 33 General purpose interrupt input.

TXD

INT3

INT2

SIO

Figure 29 IO data signal for use with external Smart Card

interface circuit such as 73S8024.

SCLK

PRES

Figure 30 Clock signal for use with external Smart Card interface

circuit.

Figure 41 Smart Card presence. Active high. Note: the pin has a

very weak pull down resistor. In noisy environments,

an external pull down may be desired to insure against

a false card event.

PRES

Figure 42 Smart Card presence. Active low. Note: the pin has a

very weak pull up resistor. In noisy environments, an

external pull up may be desired to insure against a

false card event.

CLK

RST

Figure 39 Smart card clock signal.

Figure 39 Smart card Reset signal.

Figure 40 Smart card Data IO signal.

Figure 40 Auxiliary Smart Card IO signal (C4).

Figure 40 Auxiliary Smart Card IO signal (C8).

AUX1

AUX2

VCC

PSO

Smart Card VCC supply voltage output. A 0.47μF

capacitor is required and should be located at the

smart card connector. The capacitor should be a

ceramic type with low ESR.

GND

VPC

37 GND

Smart Card Ground.

PSI

Smart Card LDO regulator power supply source. A

10μF and a 0.1μF capacitor are required at the VPC

input. The 10μF capacitor should be a ceramic type

with low ESR.

TBUS(3:0)

Trace bus signals for ICE.

RXTX

ERST

ISBR

TCLK

ICE control.
