Microchip Technology Adds PIC18FXX39 Series MCUs

January 26, 2003 by Jeff Shepard

Microchip Technology Inc. (Chandler, AZ) announced a new PIC18F family of four PICmicro® flash microcontrollers (MCUs), the PIC18F2439/2539/4439/4539 product family, which feature a single-phase motor control peripheral that provides a quick-to-market solution to simplify motor control integration. The PIC18FXX39 family provides an off-the-shelf solution for simple motor control applications, and are suitable for a wide range of industrial, consumer and appliance applications.

The single-phase (open-loop) motor control kernel utilizes standard application programming interfaces and uses on-chip, pulse-width modulation to provide speed control for single-phase induction motors. The PIC18FXX39 family includes Programmable Motor Processor Technology™ motor control that provides modulated output over a range of 0Hz to 127Hz, and has a predefined variable frequency curve that can be programmed to suit the application.

In addition to the embedded single-phase motor control kernel, the MCU family features two 10-bit PWMs; 256 bytes of on-board, high-endurance data EEPROM; and up to 10 MIPS performance at 40MHz. The PIC18FXX39 also features three all-purpose, 16-bit timers; an analog-to-digital converter with up to eight channels; 10-bit resolution; an addressable USART module supporting RS485 and RS232; a programmable 16-level, low-voltage detection module; and a wide operating voltage range of 2.0, -5.5V.

Available packages include 28-pin SOIC and SDIP, 40-pin PDIP, and 44-lead TQFP and QFN. The PIC18FXX39 family is priced between $4.28 and $5.15 in volume manufacturing quantities depending on device, temperature range, package and operating voltage. Samples and volume-production quantities are available now.
