Description

GENERAL DESCRIPTION
The PIC16F8X is a group in the PIC16CXX family of low-cost, high-performance, CMOS, fully-static, 8-bit microcontrollers. This group contains the following devices:
• PIC16F83
• PIC16F84
• PIC16CR83
• PIC16CR84

All PICmicro™ microcontrollers employ an advanced RISC architecture. PIC16F8X devices have enhanced core features, eight-level deep stack, and multiple internal and external interrupt sources. The separate instruction and data buses of the Harvard architecture allow a 14-bit wide instruction word with a separate 8-bit wide data bus. The two stage instruction pipeline allows all instructions to execute in a single cycle, except for program branches (which require two cycles). A total of 35 instructions (reduced instruction set) are available. Additionally, a large register set is used to achieve a very high performance level.

High Performance RISC CPU Features:
• Only 35 single word instructions to learn
• All instructions single cycle except for program branches which are two-cycle
• Operating speed: DC - 10 MHz clock input
                       DC - 400 ns instruction cycle
       
• 14-bit wide instructions
• 8-bit wide data path
• 15 special function hardware registers
• Eight-level deep hardware stack
• Direct, indirect and relative addressing modes
• Four interrupt sources:
   - External RB0/INT pin
   - TMR0 timer overflow
   - PORTB<7:4> interrupt on change
   - Data EEPROM write complete
• 1000 erase/write cycles Flash program memory
• 10,000,000 erase/write cycles EEPROM data memory
• EEPROM Data Retention > 40 years

Peripheral Features:
• 13 I/O pins with individual direction control
• High current sink/source for direct LED drive
   - 25 mA sink max. per pin
   - 20 mA source max. per pin
• TMR0: 8-bit timer/counter with 8-bit programmable prescaler

Special Microcontroller Features:
• In-Circuit Serial Programming (ICSP™) - via two pins (ROM devices support only Data EEPROM programming)
• Power-on Reset (POR)
• Power-up Timer (PWRT)
• Oscillator Start-up Timer (OST)
• Watchdog Timer (WDT) with its own on-chip RC oscillator for reliable operation
• Code-protection
• Power saving SLEEP mode
• Selectable oscillator options

CMOS Flash/EEPROM Technology:
• Low-power, high-speed technology
• Fully static design
• Wide operating voltage range:
   - Commercial: 2.0V to 6.0V
   - Industrial: 2.0V to 6.0V
• Low power consumption:
   - < 2="" ma="" typical="" @="" 5v,="" 4="">
   - 15 µA typical @ 2V, 32 kHz
   - < 1="" µa="" typical="" standby="" current="" @="">
