Fujitsu Microelectronics has added three low pin count microcontrollers. The devices with 8, 16, and 20 pins are in its F2MC-8FX family of 8-bit microcontrollers.
According to the supplier, there is growing demand in Asia for low pin count 8-bit microcontrollers for use in small home appliances.
Now Fujitsu has launched the MB95260H series, MB95270H series, and MB95280H series which include the addition of on-chip dual-operation flash memory. Which means designs can save on external E2PROM.
The dual-operation flash memory is designed to emulate E2PROM. The memory contains two regions, one region for program storage, and another region that can be used for data storage and acts as a substitute for E2PROM.
“This allows a reduction in system area and system cost, as an external E2PROM is not required,” said the supplier.
The embedded flash memory is specified up to 100,000 re-writes.
The MCUs also employ a 1-line on-chip debug that uses only one pin on the microcontroller. This minimises the number of pins used for debugging in product development.
Fujitsu Microelectronics is providing the starter kit, MB2146-420A-01-E, which includes a product development environment in a single package.
