The ultra low power RL78/L1A microcontroller family with embedded LCD has enhanced analog peripherals such as 12bit A/D converters, 12bit D/A converters, comparators, high accuracy rail to rail operational amplifiers with switch fabrics and comes with memory up to 128kb flash. Using the smart features like DTC and ELC a lot of peripherals can be connected internally to reduce CPU workload and can save overall power consumption.

Available in 80pin and 100pin LFQFP packages, this MCU line has been developed especially for healthcare bio-sensing applications such as blood glucose meter. It is also suitable for many other appliances which needs low power with LCD and rich analog peripherals.

Features

  • CPU: RL78 core, Max. 24MHz
  • Voltage: 1.8V to 3.6V
  • Package: 80 to 100-pin QFP
  • Memory: SRAM Max. 5.5KB, Program Flash Max. 128KB

Applications

  • Healthcare
  • Home Appliance
