78K0R development kit

NEC Electronics Europe is offering the 78K0R development kit designed for the evaluation of the company's 16bit 78K0R/Lx3 microcontroller.

Dubbed "Sense it!", the 78K0R/Lx3 development kit includes an on-chip LCD driver circuit, optimized especially for the fields of handheld healthcare diagnostic instruments such as blood glucose meter, building utility meters and heating controls, and human machine interface for industrial automation and motor drives.

The 78K0R/Lx3 16bit microcontroller family offers 25.4 DMIPS of performance at 20MHz and at very low power. It draws 0.19mA of current in operation mode running at 1MHz, 0.37?A in stop mode and 0.9?A in halt mode at 32kHz with RTC on.

The 16bit MCU family has all the necessary functions to construct systems using LCD segmented displays, including LCD control that supports LCD booster, resistor bias and capacitor split drive modes.

A high performance analogue front-end can be implemented, supported by a 12-channel x 12bit SAR A/D converter, a two-channel x 12bit DAC, three-channel x op amps and an internal voltage reference (2V and 2.5V).

The Sense it! kit includes the 128-pin 78K0R/LH3 device with 128Kbyte of flash and 7Kbyte of RAM. Several peripheral functions are also mounted on the board including a 400 segment LCD, thermometer, light meter, voltage meter, buzzer, five-way mini joystick, DIP switches, a prototyping area and audio output for sound/voice playback using ADPCM.

The kit also contains 16Kbyte code limited version of the IAR Embedded Workbench software development tool and several demonstration programs. The starter kit can be powered using the on-board USB port, which also can be utilized to load the demonstration programs.

In addition the on-board interface for the MINICUBE2 offers low cost support for source code debugging and emulation through dedicated hardware and the IAR environment.
