- Memory: SRAM Max. 5.5KB, Program Flash Max. 128KB
Description
The ultra-low power RL78/L1A microcontroller family with embedded LCD has enhanced analog peripherals such as 12-bit A/D converters, 12-bit 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 80-pin and 100-pin LFQFP packages, this MCU line has been developed especially for healthcare biosensing applications such as blood glucose meters. It is also suitable for many other appliances which need low power with LCD and rich analog peripherals.
