RL78/G23 is compatible with the RL78/G13, G14 pin assignment. In particular, the RL78/G13 lineup is represented by pink cells. Shown here is a lineup of various memory, pins, and package that can be smoothly migrated from the existing RL78. In addition, the designer has added a lineup of 768kB because the designer needs a lot of ROM for raising IoT edge performance.
