Datasheet
RL78/G1P
RENESAS MCU
True low-power platform (66 μA/MHz, and 0.31 μA for LVD) for the general-purpose and sensor control applications, with 2.7-V to 3.6-V operation,
low pin counts (24 or 32 pins), small ROM capacity (16 Kbytes), and highly-functional analog circuits (12-bit A/D and 10-bit D/A converters)
