8-BIT MCU WITH SINGLE VOLTAGE FLASH MEMORY,
ADC, 16-BIT TIMERS, SPI, SCI INTERFACES
s Memories
– 8K or 16K Program memory (ROM or single
voltage FLASH) with read-out protection and
in-situ programming (remote ISP)
– 256 bytes EEPROM Data memory (with read-
out protection option in ROM devices)
– 384 or 512 bytes RAM
s 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
– 4 Power Saving Modes: Halt, Active-Halt,
Wait and Slow
– Beep and clock-out capabilities
s Interrupt Management
– 10 interrupt vectors plus TRAP and RESET
– 15 external interrupt lines (4 vectors)
s 44 or 32 I/O Ports
– 44 or 32 multifunctional bidirectional I/O lines:
– 21 or 19 alternate function lines
– 12 or 8 high sink outputs
s 4 Timers

– Realtime base
– Two 16-bit timers with: 2 input captures (only
one on timer A), 2 output compares (only one
on timer A), External clock input on timer A,
PWM and Pulse generator modes
s 2 Communications Interfaces
– SPI synchronous serial interface
– SCI asynchronous serial interface (LIN com-
patible)
