Fujitsu launches new series MCU with built-in touch interface

MBB95850/860/870 series is based on 8-bit microcontroller F2MC-New8FX Family

By CBR Staff Writer

Fujitsu Semiconductor Asia has launched new MBB95850/860/870 series MCU with in-built dual FLASH capacitive touch interface.

The new series includes two 24-pin MB95856 series equipped with high-sensitivity capacitive touch interface, one 32-pin MB95866 series and two 48/52-pin MB95876 series.

MBB95850/860/870 series is based on 8-bit microcontroller F2MC-New8FX Family and it uses 180nm technologies to achieve a high energy-efficiency design, the company said.

Fujitsu’s new series MCU utilises APIS (Adjacent Pattern Interference Suppression) and AIC (Configurable Automatic Impedance Calibration) touch technology, which enable touch MCU to accurately identify touch input at various temperatures and in humidity environment and under different ground conditions and complex working conditions.

The new series uses dual channel FLASH technology, which makes the programme run in FLASH and read/write operation on another channel at the same time.

It adopts single wire on-chip debug function, which facilitate the customers in debugging by using the least number of pins.

MBB95850/860/870 series employs common development tools and software development environment, adopts three different kinds of APIS modes to filter out malfunction and false trigger on the hardware level and uses automatic impedance correction technology (AIC) to adjust to different working environment and conditions.
