ADC, 16-BIT TIMERS, SPI, I C INTERFACES

PRELIMINARY DATA

■ Memories

– 4K or 8K bytes Program memory (ROM and

single voltage FLASH) with read-out protec-

tion and in-situ programming (remote ISP)

– 256 bytes RAM

■ Clock, Reset and Supply Management

– Enhanced reset system

SDIP32

SO28

– Enhanced low voltage supply supervisor with

3 programmable levels

– Clock sources: crystal/ceramic resonator os-

cillators or RC oscillators, external clock,

backup Clock Security System

– Clock-out capability

– 3 Power Saving Modes: Halt, Wait and Slow

■ Interrupt Management

– 7 interrupt vectors plus TRAP and RESET

– 22 external interrupt lines (on 2 vectors)

■ 22 I/O Ports

■ Instruction Set

– 8-bit data manipulation

– 63 basic instructions

– 17 main addressing modes

– 8 x 8 unsigned multiply instruction

– True bit manipulation

– 22 multifunctional bidirectional I/O lines

– 14 alternate function lines

– 8 high sink outputs

■ 3 Timers

– Configurable watchdog timer

– Two 16-bittimers with: 2 input captures, 2 out-

put compares, external clock input on one tim-

er, PWM and Pulse generator modes

■ Development Tools

– Full hardware/softwaredevelopment package

(one only on ST72104Gx and ST72216G1)

■ 2 Communications Interfaces

– SPI synchronous serial interface

– I2C multimaster interface

(only on ST72254Gx)

■ 1 Analog peripheral

– 8-bit ADC with 6 input channels

(except on ST72104Gx)
