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)

Note The flash libraries use the on-chip RAM area from FFE20H to FFEFF H and the parts of the RAM area referred to
as self RAM (RAM for use in self-programming), which are listed in the table below, for self-programming or
rewriting of the data flash memory.
See below for the RAM areas used by the flash library.
