Overview

RL78/L1A MCUs from Renesas Electronics have on-chip high-precision 12-bit A/D converters, programmable gain Rail-to-Rail Amplifier with analog switch, D/A converter and voltage reference that are ideal for blood glucose level measurement. They also integrate the peripheral functions as LCD control, oscillator and flash memory required for a blood glucose monitor, which helps to reduce overall cost and extend battery life.
