ST7LITEUSx
8-bit MCU with single voltage Flash memory,
ADC, timers
Features
■ Memories
– 1K bytes single voltage Flash Program mem-
ory with read-out protection, In-Circuit and In-
Application Programming (ICP and IAP). 10K
write/erase cycles guaranteed, data retention:
20 years at 55°C.
– 128 bytes RAM.
■ 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 trimmable 8MHz RC
oscillator, internal low power, low frequency
RC oscillator or external clock
– Five Power Saving Modes: Halt, Auto Wake
Up from Halt, Active-Halt, Wait and Slow
■ Interrupt Management
– 11 interrupt vectors plus TRAP and RESET
– 5 external interrupt lines (on 5 vectors)
■ I/O Ports
– 5 multifunctional bidirectional I/O lines
– 1 additional Output line
– 6 alternate function lines
– 5 high sink outputs
■ 2 Timers
– One 8-bit Lite Timer (LT) with prescaler in-
cluding: watchdog, one realtime base and one
8-bit input capture.
– One 12-bit Auto-reload Timer (AT) with output
compare function and PWM
