Fujitsu Semiconductor Launches 8-bit Microcontroller

Fujitsu Semiconductor Asia Pte Ltd (FSAL) today announced the development of a new series in its F2MC-8FX family of high-performance 8-bit microcontrollers with embedded flash memory. The new 32-pin MB95430H series include six products with built-in analog comparator and operational amplifier.

Samples of the new products are currently available, with volume shipping to start in October 2010.

The MB95430H series, is launched to meet the rapidly growing demand for 8-bit microcontrollers of small system control embedding comparator and amplifier function, especially in Asia markets. The new products are targeted for use in home appliances and industrial equipment - such as induction cookers, power tools and auto-testers.

In addition to its primary function as main microcontroller unit, the new MB95430H series is also suitable as a sub-controller when current system configuration functions are insufficient, due to the availability of high current protection and various composite timer communication functions.

This series also employs a one-wire on-chip debug module that uses only one pin on the microcontroller for debugging, thus facilitating easier and faster product development. Furthermore, high-precision CR oscillation circuit is built into the microcontroller as its system clock source so as to reduce the external components for customer\'s development when necessary.

Product Features

1) Four comparators and one operational amplifier
The microcontrollers are equipped with multiple voltage comparators and operational amplifiers, which can be applied to various high-speed samples, alarm circuits, auto-control circuits and measurement techniques, as well as fields concerning circuit break protection, quick sensors, power supply voltage supervisor circuits, zero-crossing detection circuits, etc. In addition, the microcontrollers are mainly used in induction cookers, microwave ovens, circuit breakers, protection devices, monitoring devices, monitoring instrument sand high power supply equipment, etc.

2) High-performance flash memory
The microcontrollers incorporate Fujitsu\'s high reliability, high-performance embedded flash memory that can be re-written 100,000 times and guaranteed to hold data for 20 years. A flash security function protects customers\' software from being read by unauthorized external programmers.

3) Reduced system cost due to integration of external components
As the internal CR oscillating circuit and the low-voltage detection circuit are built into the microcontrollers, the need for an external oscillator and reset IC is eliminated, thus contributing to a reduction in overall system costs.
