Sunnyvale, Ca. — Fujitsu Microelectronics America has just introduced its new, low-pin-count MB95200series of 8-bit microcontrollers (MCUs) designed for cost-sensitive consumer applications.
The MB95200 series is an extension of the popular Fujitsu FMC-8FX family of 8-bit microcontrollers. The new series includes a complete range of single-chip standard microcontrollers with between 8 and 24 pins, powered by an optimized core and featuring low-leakage technology and embedded flash.
Fast processing capabilities and low power consumption position the MB95200 series as an excellent design choice for appliances such as washing machines, refrigerators, ovens, smoke detectors, vacuum cleaners and air conditioning units.
According to Dean Chang, senior product marketing manager, Fujitsu Microelectronics, the MCUs are also ideal for cordless phones and remote controls, shavers and other handheld consumer products, as well as aftermarket automotive accessories.
The microcontrollers are embedded with Fujitsu's high-reliability, high-performance flash memory that can be rewritten 100,000 times and is guaranteed to hold data for 20 years. A flash security function protects the customer's software from being read by unauthorized external programs.
The MB95260/270/280 MCUs include Fujitsu Microelectronics' proprietary embedded dual-operation flash memory, which emulates EPROM. The memory contains two regions, one for program storage, and the other for data storage. Because it acts as a substitute for EPROM, the dual operation flash memory eliminates the need for external EPROM, reducing system area and system cost.
An internal CR oscillating circuit (that runs the operating clock) and the low-voltage detection circuit (that detects a drop in voltage) are built into the microcontrollers. This level of integration eliminates the need for an external oscillator and reset IC, contributing to a reduction in overall system costs.
The MCUs include a “composite timer,” channel can be selected from any one of the following, depending on the program: pulse width modulation (PWM), pulse width counter (PWC), interval timer or input capture. The latter measures interval times, enabling the flexibility needed to handle varying system requirements.
The devices will also be provided with a low-cost development environment with on-chip debugging tools and complimentary C-language IDE SOFTUNE design kits and tools.
The complete debug system platform consists of SOFTUNE, the MB95200 series MCU, and user board in a compact BGMA that measures just 128mm x 55mm x 29mm. To help developers use the MCUs and design environment, complete support is available on the web with datasheets, manuals, application notes, example software and a C-library.
The Fujitsu MB95200 series is available now in SOP8/DIP8, SOP16/DIP16 and SOP20/DIP24 packages. Prices range from $0.35 to $0.70 in 10,000-unit quantities depending on packaging and memory sizes. Future devices are under development and will include new features such as motor control and an LCD controller.
