Fujitsu Adds Low Pin Count Series to Line of
High-Performance 8-bit Microcontrollers for Consumer Appliances

In recent years, there has been rapidly growing demand in Asia for LPC 8-bit microcontrollers for use in home appliances and other consumer electronics products, such as water heaters, electric pots, dehumidifiers, and hair dryers. In response to these needs, Fujitsu Microelectronics has added the following LPC series to its F²MC-8FX family of high-performance 8-bit microcontrollers with embedded flash memory: the 8-pin MB95210H series, 16-pin MB95220H series, and the 20-pin MB95200H series.

Aside from their use as main microcontrollers, the new series can also be used as sub-microcontrollers - for example when as a result of system specification changes in high-performance audio-visual equipment, the functions of the I/O or A/D converter⁽²⁾ of the main microcontroller or ASIC are no longer adequate.

The three new series also employ a 1-line on-chip debug that uses only one pin on the microcontroller, thereby minimizing the number of pins used for debugging in product development.

Furthermore, along with these series, Fujitsu Microelectronics is providing the MB2146-410-01-E starter kit, which is a product development environment combined as a single package.

Sales Target

4 million units in fiscal 2008 (April 2008 to March 2009)

Key Features of the New Series

1. Industry-leading class CPU performance helps improve the customer's product performance
   The new series use the F²MC-8FX CISC CPU, which offers industry-leading class performance of 8-bit microcontrollers in the industry, with a maximum operating frequency of 16.25 MHz and a minimum instruction time of 61.5 nanoseconds, thus enabling more instructions to be executed per cycle compared to other vendors’ microcontrollers. As the required processing performance can be delivered using a lower frequency, the series also contribute to enabling the customers’ products to consume less power.
2. Embedded peripheral parts results in lower costs
   Because the internal CR oscillating circuit (precision level ±2%) that runs the operating clock and the low-voltage detection circuit that detects a drop in voltage 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.
3. A composite timer that can shift timer functions provides flexibility for system requirements
   For the timer function, in the embedded composite timer, depending on the program one channel can be selected with either a pulse width counter, pulse width modulation, interval timer or input capture which measures interval times, enabling flexibility to handle differing system requirements.
