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
? 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 = ¡À1 LSb, INL = ¡À1 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
