 MB95430H series

Fujitsu Semiconductor Asia Pte Ltd has developed, and now released a new series in its F2MC-8FX family of high-performance 8bit microcontrollers with embedded flash memory. These new 32-pin MB95430H series includes six products which feature built-in analog comparator and operational amplifier.

The MB95430H series is offered to address the fast growing demand for 8-bit microcontrollers of small system control embedding comparator and amplifier function, mostly in Asian markets. These new microcontrollers can be used in home appliances and industrial equipment, such as induction cookers, power tools and auto-testers.

Other than its primary function as main microcontroller unit, the MB95430H series can also be utilized as a sub-controller, when current system configuration functions are insufficient, because of the availability of high current protection and various composite timer communication functions.

It 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. Finally, the high-precision CR oscillation circuit is built into the microcontroller as its system clock source, thereby reducing the external components if development requires it.

Product featured highlights include: Four comparators and one operational amplifier (mainly used in induction cookers, microwave ovens, circuit breakers, protection devices, monitoring devices, monitoring instruments and high power supply equipment ); High-performance flash memory with flash security function; Integration of external components such as the internal CR oscillating circuit and the low-voltage detection circuit (resulting to reduced over all system cost).

Product line-up and availability: MB95F432H and MB95F432K have 8KB ROM, and 240B RAM; MB95F433H and MB95F433K have 12KB ROM, and 240 BRAM; MB95F434H and MB95F434K have 20KB ROM, 496B RAM. Samples of these new products are now available, with shipping in volume to begin in October 2010.
