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
– 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
– 22 multifunctional bidirectional I/O lines
– 14 alternate function lines
– 8 high sink outputs
■ 3 Timers
– Configurable watchdog timer
– Two 16-bit timers with: 2 input captures, 2 out-
put compares, external clock input on one tim-
er, PWM and Pulse generator modes
(one only on ST72104Gx and ST72216G1)
■ 2 Communications Interfaces
– SPI synchronous serial interface
– I2C multimaster interface
(only on ST72254Gx)
■ 1 Analog peripheral
