ST7LITE3
8-BIT MCU WITH SINGLE VOLTAGE FLASH, DATA EEPROM, ADC,
TIMERS, SPI, LINSCI^™
■ Memories
– 8 Kbytes program memory: single voltage ex-
tended Flash (XFlash) Program memory with
read-out protection, In-Circuit Programming
and In-Application programming (ICP and
IAP), data retention: 20 years at 55°C.
– 384 bytes RAM
– 256 bytes data EEPROM with read-out pro-
tection. 300K write/erase cycles guaranteed,
data retention: 20 years at 55°C.
■ Clock, Reset and Supply Management
– Enhanced reset system
– Enhanced low voltage supervisor (LVD) for
main supply and an auxiliary voltage detector
(AVD) with interrupt capability for implement-
ing safe power-down procedures
– Clock sources: Internal RC1% oscillator, crys-
tal/ceramic resonator or external clock
– Optional x4 or x8 PLL for 4 or 8 MHz internal
clock
– Five Power Saving Modes: Halt, Active-Halt,
Wait and Slow, Auto Wake Up From Halt
■ I/O Ports
– Up to 15 multifunctional bidirectional I/O lines
– 7 high sink outputs
■ 5 Timers
– Configurable Watchdog Timer
– Two 8-bit Lite Timers with prescaler,
1 realtime base and 1 input capture
– Two 12-bit Auto-reload Timers with 4 PWM
outputs, input capture and output compare
functions
