Fujitsu MCUs Have Motor-Control Functionality

Fujitsu Microelectronics has expanded its F2MC-8FX range of low-cost, low-pin-count (LPC) microcontrollers (MCUs). MB95330K is the first Fujitsu 32-pin, 8bit MCU series to feature motor-control functionality. With fast processing, low power consumption and three-phase motor control timers, the devices are targeted for use in a range of industrial, medical and consumer applications. The series is powered by Fujitsu's 8FX CPU core and features embedded dual-operation flash memory with support for E2PROM emulation.

This allows a reduction in system area and system cost, as an external E2PROM is not required. Fujitsu's high-quality, high-performance embedded flash memory can be re-written 100,000 times and is guaranteed to hold data for 20 years. A flash security function protects customers' software from being read by unauthorised external programs. The precise RC oscillator (+/-2 per cent) and low-voltage detection circuit built into the MCUs eliminate the need for an external oscillator and reset IC, contributing further to a reduction in overall system costs.

The series also employs single-line on-chip debug and includes a I2C interface. The MB95330K series is part of Fujitsu's F2MC-8FX range, a complete range of LPC MCUs ranging from eight-pin up to 100-pin devices and is scalable in terms of memory and feature set. Future devices are currently under design and will add features such as a peripheral for controlling LCDs. The 8FX devices are the successor to the company's 8L products.

The series will be supported by detailed material on Fujitsu's website, including datasheets, manuals, application notes, example software, sensorless motor control library and C-library. Development is made easy with the compact and low-cost on-chip debugging tool and the free-of-charge C-language IDE - Softune. The MB95330K series will feature derivatives in 32-pin LQFP, SDIP and QFN packages, and will be available with 8, 12 or 20kB of flash memory and 240, 496 or 1008B of RAM.
