SPI, LINSCI™

Features

■ 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 RC 1% oscillator,

crystal/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
