8-BIT MCU WITH SINGLE VOLTAGE FLASH MEMORY,
DATA EEPROM, ADC, TIMERS, SPI
s
Memories
– 1K or 1.5K bytes single voltage Flash Pro-
gram memory with read-out protection, In-Cir-
cuit and In-Application Programming (ICP and
IAP). 10K write/erase cycles guaranteed, data
retention: 20 years at 55°C.
– 128 bytes RAM.
– 128 bytes data EEPROM with read-out pro-
tection. 300K write/erase cycles guaranteed,
data retention: 20 years at 55°C.
s
Clock, Reset and Supply Management
– 3-level low voltage supervisor (LVD) and aux-
iliary voltage detector (AVD) for safe power-
on/off procedures
– Clock sources: internal 1MHz RC 1% oscilla-
tor or external clock
– PLL x4 or x8 for 4 or 8 MHz internal clock
– Four Power Saving Modes: Halt, Active-Halt,
Wait and Slow
s
Interrupt Management

s
2 Timers
– One 8-bit Lite Timer (LT) with prescaler in-
cluding: watchdog, 1 realtime base and 1 in-
put capture.
– One 12-bit Auto-reload Timer (AT) with output
compare function and PWM
s
1 Communication Interface
