Description
The PIC16F77 devices are available in 40-pin and 44-pin packages. All devices in the PIC16F7X family share common architecture, with the following differences: The 28-pin devices have 3 I/O ports, while the 40/44-pin devices have 5 The 28-pin devices have 11 interrupts, while the 40/44-pin devices have 12 The 28-pin devices have 5 A/D input channels, while the 40/44-pin devices have 8 The Parallel Slave Port is implemented only on the 40/44-pin devices
- 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 (ICSP) via two pins Peripheral Features:
- Timer0: 8-bit timer/counter with 8-bit prescaler
- Timer1: 16-bit timer/counter with prescaler, can be incremented during SLEEP via external crystal/clock
- Timer2: 8-bit timer/counter with 8-bit period register, prescaler and postscaler
