Product Introduction

The PFC154 is an IO-Type, fully static, MTP-based controller; it employs RISC architecture and most the instructions are executed in one cycle except that few instructions are two cycles that handle indirect memory access.

PFC154 has built-in 2KW MTP program memory and 128 byte data storage.

PFC154 provides a hardware 16-bit timer, two hardware 8-bit timers with PWM generation (Timer2, Timer3) and Three hardware 11-bit timers with PWM generation (PWMG0, PWMG1, PWMG2).

PFC154 also supports one hardware comparator and VDD/2 bias voltage generator for LCD display application.
