8-bit low pin-count microcontrollers

30 June 2004 DSP, Micros & Memory

NEC Electronics (Europe) has introduced the 78K0S/Kx1+ Series of 8-bit single-chip microcontrollers. The series boasts low pin counts and small footprints. As systems become increasingly complex, interfacing with external components becomes more frequent, leading to higher pin counts as well as prices, says NEC. However, many applications require lower pin counts without sacrificing functionality.

The 78K0S/Kx1+ series uses SuperFlash single power supply flash memory licensed from SST, which offers superior 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 (LVI) enable all non-power-supply pins to be used as ports, which further help to reduce costs and board space.
