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.

Hitachi Introduces Microdrive Pump Sleep Mode Functionality
Hitachi America, Ltd., Industrial Systems Division, today announced the availability of Pump Sleep Mode functionality in its X200 And SJ200 Series Microdrives. The functionality is implemented utilizing only the inverter’s built-in PID control, logic and timing functions as a basis. Together with parameter settings, external jumper wiring is all that is required to realize the sleep mode operation.

Standard PID control may, depending on system demand, allow a pump to operate at undesirably low speeds for prolonged periods of time, which can cause mechanical issues with certain pump types. In general, it is a wasteful use of energy, since most pumps do not generate significant flow or head at low speeds. A means is needed to stop the pump when no pumping is actually taking place. The term “sleep mode” is used to describe such a means. The implementation requires no additional hardware beyond what is required for standard PID operation.
The simple set-up and wiring is described in an Application Note (AN080717-1) which is available to view or download in the Technical Support Library area of Hitachi America’s web site.
