Description

DEVICE OVERVIEW
This document contains device specific information for the following devices:

• PIC18F2439 • PIC18F4439
• PIC18F2539 • PIC18F4539

This family offers the advantages of all PIC18 microcontrollers - namely, high computational performance
at an economical price - with the addition of high-endurance Enhanced FLASH program memory. The PIC18FXX39 family also provides an off-the-shelf solution for simple motor control applications, allowing users to create speed control solutions with small part counts and short development times.

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

• 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
