Here some more details: - Software- & pinkompatible to PIC16C54, but 4 stack-levels - EPROM 512*12Bit, RAM 25 Bytes - 8 High Voltage IO Pins on Port B, 4 Low Voltage Pins - includes a voltage regulator (should work from 3.5V ... 15V) - Wake-up from Sleep through Sleep-Timer or Change on Pin Maybe anybody else knows more about it ...
