Fujitsu Expands Line-Up of Low Pin Count 8-bit Microcontrollers
Fujitsu Low Pin Count 8-bit Microcontrollers
Fujitsu Microelectronics Limited today announced the new “MB95330H series” to expand its line-up of low pin count microcontrollers, for its “F²MC-8FX family”(1) of high-performance 8-bit microcontrollers with flash memory. The new series features a brushless DC motor(2) control function, and starts with six new products. This will satisfy the needs for low pin count microcontrollers with brushless DC motor control for consumer appliances and small electric tools, such as electric drills. Samples of the new series will be available from the end of March 2010, with mass-production in June 2010.
In recent years, there has been rapidly-increasing demand in Japan and other parts of Asia for 8-bit microcontrollers with brushless DC motor control for small system control use, for home applications, OA equipment and industrial instruments. In response to these needs, Fujitsu Microelectronics has added the “MB95330H series” which features a brushless DC motor control function with only 32 pins, to its “F²MC-8FX family”.
This new series features various timers for general-purpose and communication functions, besides the brushless DC motor control function. Thus, it is suitable for use not only as a main microcontroller, but also as a sub-microcontroller which covers lack of features of the existing system configuration.
In addition, the series employs 1-line on-chip debug which uses only one pin on the microcontroller and embedded oscillation circuit etc. These enable maximizing the number of pins to be used freely and reduction of total system cost for customers.
Key Features of the New Series
- Brushless DC motor controller-The new series enables formation of suitable three-phase waves for brushless DC motor control, for use ranging from pump motors in dishwashers, to air-cooling fans in PCs.
- High-performance flash memory-The microcontrollers embed high-performance flash memory which can be rewritten/read 100,000 times even while running a program, and is guaranteed to retain the data for 20 years. Furthermore, a flash security function protects the customer’s software from unauthorized external programming.
- Reduced system cost-By embedding CR oscillating, a low voltage detection circuit and watchdog timer, the microcontrollers successfully reduce required external components, such as an oscillator and reset IC. This helps to cut down customers’ overall system cost.
