Microchip Technology has unveiled the PIC18FXX9 series of PICmicro Flash MCUs, which is targeted for efficient operation of single-phase motor control applications. The PIC18F2439/2539/4439/4539 MCUs features a single-phase (open loop) motor control kernel that offers simple development by using the APIs.

The MCUs utilizes the company's Programmable Motor Processor Technology (ProMPT) motor control that provides modulated output over the 0Hz to 127Hz frequency range, and has a pre-defined variable frequency curve that can be programmed to suit the application.

Available in 28-pin SOICs, SDIPs, and 40-pin PDIPs, the MCUs are pin and code-compatible with Microchip's current 28- and 40-pin portfolio, enabling designers to re-use software and hardware in existing platforms. The new MCUs are also available in 44-lead TQFP and QFN packages.

In addition to the embedded motor control kernel and self-reprogrammable Flash memory functions, the MCU family features two 10-bit PWMs, 256 bytes of on-board data EEPROM, up to 10MIPS performance at 40MHz.

They also feature three all-purpose 16-bit timers; 8-channel and 10-bit resolution ADC; addressable USART module supporting RS485 and RS232; programmable 16-level low-voltage detection module; and an operating voltage range from 2V to 5.5V.
