ST7DALIF2

8-bit MCU family with single voltage Flash memory,

data EEPROM, ADC, timers, SPI, DALI

Features

■ Memories

– 8 Kbytes single voltage Flash Program

memory with readout protection, In-Circuit

Programming and In-Application

programming (ICP and IAP). 10K

write/erase cycles guaranteed, data

retention: 20 years at 55°C.

– 384 bytes RAM

protection. 300K write/erase cycles

guaranteed, data retention: 20 yrs 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,

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
