New derivatives of 8-bit microcontrollers

These will be shown in Hall 9, Stand 235 at Embedded World 2009.

The new 8-bit MCUs, manufactured by NEC Electronics, feature a standby current consumption of just 0.7uA and a low operating current of 260uA at 1MHz clock frequency.

Moreover, an integrated high-speed oscillator, as well as further diverse peripheral units such as A/D converter and operational amplifier, help the user to reduce additional external components.

Thanks to an integrated high-speed A/D converter with many analogue inputs, the 16-bit versions are optimally suited for battery-operated sensor applications.

The MCUs have a current consumption of 1.0uA in standby mode with active watchdog and 6.8mA at the maximum operating frequency of 20MHz.

Because of the integrated voltage amplifier, just 1.8V is needed for rewriting of flash memories.

Thereby, a battery-fed power supply is sufficient for the reprogramming of mobile devices.

Mass production of the new 8-bit and 16-bit microcontrollers is scheduled to begin in Summer 2009.
