Low pin count 8-bit microcontroller series extended

17 November 2004 DSP, Micros & Memory

NEC Electronics is sample shipping six new products for the 78K0S/Kx1+ 8-bit microcontroller series. The three 8-pin and three 16-pin products include reset circuits, clock circuits and flash memory, making them targeted for a wide array of systems such as home appliances, sensors and battery chargers.

The 78K0S/Kx1+ series incorporates SuperFlash single power supply flash memory licensed from Silicon Storage Technology, which offers suitable re-programmability after product installation and flexibility for future software and product changes. The memory space is comprised of compact 256-byte blocks, which allows the flash to be used instead of external electrical programmable ROM (EEPROM). An 8 MHz on-chip oscillator, power-on-clear circuit (POC/POR) and low voltage indicator enable all non-power-supply pins to be used as ports, which help reduce costs and board space.

NEC also introduced two low-cost development tools to facilitate system development with the 78K0S/Kx1+ series - the MINICUBE+ in-circuit emulator and Applilet EZ development kit. The MINICUBE+ bundles an emulator, debugging software, and flash programming tools in a single package. Applilet EZ includes system function settings, programming and testing functions.
