Fujitsu debuts series of MCUs for advanced touch interface

BANGALORE, INDIA: With high security, high precision and cost-effective dual FLASH built-in a capacitive touch interface, Fujitsu Semiconductors unveils the MBB95850/860/870 series of microcontrollers (MCUs). The devices include two 24-pin MB95856 devices equipped with high-sensitivity capacitive touch interface, one 32-pin MB95866, and two 48/52-pin MB95876 devices.

The series uses Adjacent Pattern Interference Suppression (APIS) and Configurable Automatic Impedance Calibration (AIC) touch technology and is based on the 8bit MCUF2MC-8FX Family. It also enables touch MCU to identify touch input at various temperatures and in humid environments.

The device comes with a built-in capacitive touch peripheral unit that makes capacitive touch function user friendly. The product does not need an additional software overhead as it supports capacitive touch button and slider functions, while its hardware supports capacitive touch functionality.

The series integrates various timers with multiple channels and high versatility, 10bit high resolution A/D convertor, oscillation circuit, low-voltage detection circuit, UART/SIO circuit, I2C circuit and built-in one-channel analogue comparator, which greatly reduces the number of components in the customer's system and improves product integration accordingly.

To protect important customer data, this series employs dual channel FLASH technology. The MBB95850/860/870 series adopts single wire on-chip debug function, which assists customers in debugging by using the least number of pins.

The MB95850 series will be delivered in July, 2012 for Rs. 109.29, MB95860 series for Rs.136.61 and MB95870 series for Rs.163.93. Both the MB95860 series and MB95870 series will be available for delivery starting June 2012. Mass production delivery starts from September 2012.
