GENERAL DESCRIPTION
The PIC16C8X is a group in the PIC16CXX family of low-cost, high-performance, CMOS, fully-static, 8-bit microcontrollers. This group contains the following devices:
? PIC16C83
? PIC16CR83
? PIC16C84
? PIC16C84A
? PIC16CR84
All PIC16/17 microcontrollers employ an advanced RISC architecture. PIC16CXX 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 gives some of the architectural innovations used to achieve a very high performance.
High Performance RISC CPU Features
? Only 35 single word instructions to learn
? All instructions single cycle (400 ns @ 10 MHz) 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 interrupt on change
- Data EEPROM write complete
? 1,000,000 data memory EEPROM ERASE/WRITE cycles - Typical
? 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
? 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
? Serial In-System Programming - via two pins
(ROM devices support only Data EEPROM programming)
CMOS Technology
? Low-power, high-speed CMOS EEPROM 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 MHz
- 15 ?A typical @ 2V, 32 kHz
