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

- Multiple LCD timing sources available

- Can drive LCD panel while in Sleep mode

- Static, 1/2, 1/3, 1/4 multiplex

- Static drive and 1/3 bias capability

- 16 bytes of dedicated LCD RAM

- Up to 32 segments, up to 4 commons

• Synchronous Serial Port (SSP) with SPI and I2C

• 8-bit multi-channel Analog to Digital converter (PIC16C924 only)

Special Microcontroller Features:

• Power-on Reset (POR)

• Power-up Timer (PWRT) and Oscillator Start-up Timer (OST)

• Watchdog Timer (WDT) with its own on-chip RC oscillator for reliable operation

• Programmable code-protection

• Power saving SLEEP mode

• Selectable oscillator options

• In-Circuit Serial Programming™ (via two pins)
