PIC16C7X Microcontroller Core Features:
PIC16C7X Peripheral Features:
• High-performance RISC CPU
• Only 35 single word instructions to learn
• Timer0: 8-bit timer/counter with 8-bit prescaler
• All single cycle instructions (200 ns) except for
program branches which are two cycle
• Timer1: 16-bit timer/counter. TMR1 can be incre-
mented during sleep via external crystal/clock
• Operating speed: DC - 20 MHz clock input
DC - 200 ns instruction cycle
• Timer2: 8-bit timer/counter with 8-bit period regis-
ter, prescaler and postscaler
• Interrupt capability
• Capture, Compare, PWM module(s)
• Eight level deep hardware stack
• Direct, indirect and relative addressing modes
• Power-on Reset (POR)
• Capture is 16-bit, max. resolution 12.5 ns, com-
pare is 16-bit, max. resolution 200 ns, max. PWM
resolution is 10-bit
• Synchronous Serial Port (SSP) with SPI
• Power-up Timer (PWRT) and Oscillator Start-up
Timer (OST)
2
and I C
• Universal Synchronous Asynchronous Receiver
Transmitter (USART/SCI)
• Watchdog Timer (WDT) with its own on-chip RC
oscillator for reliable operation
• Parallel Slave Port (PSP) 8-bit wide, with external
RD, WR and CS controls
• Programmable code-protection
• Power saving SLEEP mode
• Brown-out detection circuitry for Brown-out Reset
(BOR)
• Selectable oscillator options
• 8-bit multichannel analog-to-digital converter
