PIC16F85/86
18/20 Pin, 8-Bit CMOS FLASH Microcontroller
with Comparators and A/D Product Brief
High Performance RISC CPU:
• Only 35 single word instructions to learn
• All single-cycle instructions, except for program
branches which are two-cycle
• Operating speed:
- DC - 20 MHz clock input
- DC - 200 ns instruction cycle
• Up to 2K x 14 FLASH program memory
• 128 x 8 general purpose registers (SRAM)
• 64 x 8 on-chip EEPROM data memory
• Eight levels deep hardware stack
• Interrupt capability
• Direct, Indirect and Relative Addressing modes
Peripheral Features:
• High current sink/source (25 mA/25 mA)
• Timer0 module: 8-bit timer/counter with
8-bit prescaler
• Four channel, 8-bit Analog-to-Digital Converter
(ADC) module
• Two analog comparators with:
- Programmable on-chip voltage reference
- Programmable input multiplexing from device
inputs and internal voltage reference
- Comparator outputs are externally accessible
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
• Power saving SLEEP mode
• Selectable oscillator options
• Serial In-Circuit Programming (ICSP™) via two pins
• Only single 5V supply required for programming
• Processor read/write access to program memory
• Brown-out Reset circuitry
• In-Circuit Debug (ICD) via two pins
