ST7LITE1
8-BIT MCU WITH SINGLE VOLTAGE FLASH MEMORY,
DATA EEPROM, ADC, 4 TIMERS, SPI
■ Memories
– 4 Kbytes single voltage extended Flash
(XFlash) Program memory with read-out pro-
tection, In-Circuit Programming and In-Appli-
cation programming (ICP and IAP). 10K write/
erase cycles guaranteed, data retention: 20
years at 55°C.
– 256 bytes RAM
– 128 bytes data E²PROM with read-out protec-
tion. 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 1% RC oscillator (on
some devices), crystal/ceramic resonator or
external clock
– Internal 32-MHz input clock for Auto-reload
timer
– Optional x4 or x8 PLL for 4 or 8 MHz internal
clock
– Five Power Saving Modes: Halt, Active-Halt,
Auto Wake-up from Halt, Wait and Slow
■ I/O Ports
– Up to 15 multifunctional bidirectional I/O lines
– 7 high sink outputs
■ 4 Timers
– Configurable watchdog timer
– Two 8-bit Lite Timers with prescaler,
