NEC Electronics' "SENSE IT!" starter kit, now available from Gleichmann Electronics, is ideally suited for development of low power LCD controls for portable measurement devices.
The kit is based on a 16bit microcontroller (MCU) of the 78K0R/Lx3 family with 128 KB flash and 7 KB of RAM. Features of the MCU include ultra low power consumption, with 0.19 mA current consumption in active mode at 1 MHz, 0.9 ?A current consumption in halt mode at 32 kHz with active calendar timer and 0.37 ?A current consumption in stop mode.
A 12 channel 12bit SAR A/D converter, a 2 channel 12bit D/A converter, 3 operational amplifiers as well as internal 2.0 V and 2.5 V voltage references are available for a high performance analog frontend. Additional features include a 12 channel 16bit timer array unit, a selectable internal clock frequency of 1 MHz or 8 MHz (up to 20 MHz is possible with an external clock supply), a 2 channel DMA controller, multimaster I2C, a 16 x 16bit hardware multiplier, a 32/32bit hardware divider as well as undervoltage detection and poweron reset. The LCD controller/driver integrated in the MCU can control LCDs either by means of an integrated voltage booster, an internal or external resistor chain or via a capacitive voltage divider.
Among other things, a 400 segment LCD, thermometer, light sensor, voltage meter, buzzer, a 5 way mini joystick, DIP switches and an audio output for sound and voice output with ADPCM are also integrated on the board. An onchip debugging or programming of the MCU can be carried out via the USB port provided on the starter kit. Alternatively, the possibility exists to connect the NEC OCD Emulator QB-MINI2 to the board.
The "SENSE IT!" starter kit also contains a 16 KB code limited version of the IAR Embedded Workbench software development platform as well as several example programs.
