ª 7/99 Microchip Technology Inc. Preliminary DS39026B-page 1
High Performance RISC CPU:
• C-compiler optimized architecture/instruction set
- Source code compatible with the PIC16CXX
instruction set
• Linear program memory addressing to 2M bytes
• Linear data memory addressing to 4K bytes
• Up to 10 MIPs operation:
- DC - 40 MHz osc./clock input
- 4 MHz - 10 MHz osc./clock input with PLL active
• 16-bit wide instructions, 8-bit wide data path
• Priority levels for interrupts
• 8 x 8 Single Cycle Hardware Multiplier
Peripheral Features:
• High current sink/source 25 mA/25 mA
• Three external interrupt pins
• Timer0 module: 8-bit/16-bit timer/counter with
8-bit programmable prescaler
• Timer1 module: 16-bit timer/counter
• Timer2 module: 8-bit timer/counter with 8-bit
period register (time-base for PWM)
• Timer3 module: 16-bit timer/counter
• Secondary oscillator clock option - Timer1/Timer3
•Two Capture/Compare/PWM (CCP) modules. CCP
pins that can be configured as:
- Capture input: capture is 16-bit,
max. resolution 6.25 ns (TCY/16)
- Compare is 16-bit, max. resolution 100 ns (TCY)
- PWM output: PWM resolution is 1- to 10-bit.
Max. PWM freq. @:8-bit resolution = 156 kHz
10-bit resolution= 39 kHz
• Master Synchronous Serial Port (MSSP) module.
Two modes of operation:
- 3-wire SPI™ (supports all 4 SPI modes)
-I
2
C™ master and slave mode
• Addressable USART module:
- Supports interrupt on Address bit
• Parallel Slave Port (PSP) module
Pin Diagrams
Analog Features:
• 10-bit Analog-to-Digital Converter module (A/D)
with:
- Fast sampling rate
- Conversion available during sleep
- DNL = ±1 LSb, INL = ±1 LSb
• Programmable Low-Voltage Detection (LVD)
module
- Supports interrupt on low voltage detection
• Programmable Brown-out Reset (BOR)
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 including:
- 4X Phase Lock Loop (of primary oscillator)
- Secondary Oscillator (32 kHz) clock input
• In-Circuit Serial Programming (ICSP™) via two pins
CMOS Technology:
• Low-power, high-speed EPROM technology
• Fully static design
• Wide operating voltage range (2.5V to 5.5V)
• Industrial and Extended temperature ranges
• Low-power consumption
