• Up to 160 ns instruction cycle:
- DC - 25 MHz clock input
- 4 MHz - 6 MHz 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
• Up to 47 I/O pins with individual direction control
• Three external interrupt pins
• Timer0 module: 8-bit/16-bit timer/counter with
8-bit programmable prescaler
• Timer1 module: 16-bit timer/counter (time-base for
CCP)
• Timer2 module: 8-bit timer/counter with 8-bit
period register
• Timer3 module: 16-bit timer/counter
• Secondary oscillator clock option - Timer1/Timer3
• Two Capture/Compare/PWM (CCP) modules
CCP pins can be configured as:
- Capture input: 16-bit, max. resolution 10 ns
- Compare is 16-bit, max. resolution 160 ns (TCY)
- PWM output: PWM resolution is 1- to 10-bit
Max. PWM freq. @:
8-bit resolution = 99 kHz
10-bit resolution = 24.4 kHz
• Master Synchronous Serial Port (MSSP) with two
modes of operation:
- 3-wire SPI™ (Supports all 4 SPI modes)
- I2C™ Master and Slave mode
• Addressable USART module: Supports Interrupt
on Address bit
Advanced 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
- Up to 12 channels available
• Programmable Low Voltage Detection (LVD)
module
- Supports interrupt on Low Voltage Detection
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
• On-chip Boot RAM for boot loader application
• 8-bit or 16-bit external memory interface modes
• Up to two software programmable chip select sig-
nals (CS1 and CS2)
• One programmable chip I/O select signal (CSIO)
for memory mapped I/O expansion
• Power saving SLEEP mode
• Different oscillator options, including:
- 4X Phase Lock Loop (of primary oscillator)
- Secondary Oscillator (32 kHz) clock input
CMOS Technology:
• Low power, high speed CMOS technology
• Fully static design
• Wide operating voltage range (2.0V to 5.5V)
• Industrial and Extended temperature ranges
• Low power consumption
