GENERAL DESCRIPTION

The PIC16C9XX is a family of low-cost, high-performance, CMOS, fully-static, 8-bit microcontrollers with an integrated LCD Driver module, in the PIC16CXXX mid-range family.

Microcontroller Core Features:

? High performance RISC CPU

? Only 35 single word instructions to learn

? 4K x 14 on-chip EPROM program memory

? 176 x 8 general purpose registers (SRAM)

? All single cycle instructions (500 ns) except for program branches which are two-cycle

? Operating speed: DC - 8 MHz clock input DC - 500 ns instruction cycle

? Interrupt capability

? Eight level deep hardware stack

? Direct, indirect and relative addressing modes

Peripheral Features:

? 25 I/O pins with individual direction control

? 25-27 input only pins

? Timer0: 8-bit timer/counter with 8-bit prescaler

? Timer1: 16-bit timer/counter, can be incremented during sleep via external crystal/clock

? Timer2: 8-bit timer/counter with 8-bit period register, prescaler and postscaler

? One pin that can be configured a capture input, PWM output, or compare output

- Capture is 16-bit, max. resolution 31.25 ns

- Compare is 16-bit, max. resolution 500 ns

- PWM max resolution is 10-bits. Maximum PWM frequency @ 8-bit resolution

= 32 kHz, @ 10-bit resolution = 8 kHz

? Programmable LCD timing module
