RL78/G11

Low pin and internal configurable analog MCU

 

The RL78/G11 microcontroller line-up concept is based on small packages like 20 to 25pin, in small 16KB flash memory and rich analog peripherals such as A/D converters, D/A converters, comparators and PGA and these are configurable as PGA+ADC+VBGR, PGA+CMP, CMP+DAC/VBGR, or PGA+CMP+DAC/VBGR. 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.  It also supports very low power operation (100 uA @ 1 MHz ) and a high speed 4µs wake up. Available in small 3x3mm² WFLGA , 4x4mm² HWQFN and standard 20pin LSSOP, this MCU line is suitable for sensor application, Lighting/power sources and many small appliances.
