High Performance RISC CPU:

• Linear program memory addressing to 24 Kbytes

• Linear data memory addressing to 1.4 Kbytes

• 20 MHz operation (5 MIPs):

- 20 MHz oscillator/clock input

- 5 MHz oscillator/clock input with PLL active

• 16-bit wide instructions, 8-bit wide data path

• 8 x 8 Single Cycle Hardware Multiplier

Special Microcontroller Features:

• 100,000 erase/write cycle Enhanced FLASH

program memory typical

• 1,000,000 erase/write cycle Data EEPROM memory

• FLASH/Data EEPROM Retention: > 100 years

• Power-on Reset (POR), Power-up Timer (PWRT)

and Oscillator Start-up Timer (OST)

• Programmable code protection

• Power saving SLEEP mode

• Single supply 5V In-Circuit Serial Programming™

(ICSP™) via two pins

• In-Circuit Debug (ICD) via two pins

Analog Features:

• Compatible 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 (PLVD)

- Supports interrupt on Low Voltage Detection

• Programmable Brown-out Reset (BOR)

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

• Timer3 module: 16-bit timer/counter

• Secondary oscillator clock option - Timer1/Timer3

• Two PWM modules:

- Resolution is 1- to 10-bit,

Max. PWM freq. @ 8-bit resolution = 156 kHz

10-bit resolution = 39 kHz

• Single Phase Induction Motor Control kernel

- Programmable Motor Control Technology

(ProMPT™) provides open loop Variable

Frequency (VF) control

- User programmable Voltage vs. Frequency

curve

- Most suitable for shaded pole and permanent

split capacitor type motors

• Master Synchronous Serial Port (MSSP) module

with two modes of operation:

- 3-wire SPI™ (supports all 4 SPI modes)

-I2C™ Master and Slave mode

• Addressable USART module:

- Supports RS-485 and RS-232

• Parallel Slave Port (PSP) module

CMOS Technology:

• Low power, high speed FLASH/EEPROM

technology

• Fully static design

• Wide operating voltage range (2.0V to 5.5V)

• Industrial and Extended temperature ranges
