Description
ST7LITE1xB
8-BIT MCU WITH SINGLE VOLTAGE FLASH MEMORY, DATA EEPROM, ADC, 5 TIMERS, SPI
■ Memories
– up to 4 Kbytes single voltage extended Flash (XFlash) Program memory with read-out protection, In-Circuit Programming and In-Application programming (ICP and IAP). 10K write/ erase cycles guaranteed, data retention: 20 years at 55°C.
– 256 bytes RAM
– 128 bytes data EEPROM with read-out protection. 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 implementing safe power-down procedures
– Clock sources: Internal 1% RC oscillator (on ST7FLITE15B and ST7FLITE19B), 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 17 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
