Low-Pin-Count 8-Bit MCUs Suit Cost-Sensitive Appliance Applications

A low-pin-count series of 8-bit microcontrollers are designed for cost-sensitive consumer appliance applications. The MB95200 series consists of a 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 make the MB95200 series a good design choice for appliances such as washing machines, refrigerators, ovens, smoke detectors, vacuum cleaners and air conditioning units. The MCUs are embedded with high-reliability, high-performance flash memory that can be rewritten 100,000 times and is guaranteed to hold data for 20 years. The proprietary embedded dual-operation flash memory, which emulates E²PROM, contains two regions, one for program storage, and the other for data storage. An internal CR oscillating circuit (that runs the operating clock) and the low-voltage detection circuit are built into the microcontrollers. In the embedded “composite timer,” a 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 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.
