This slide indicates RL78/G15 functions. RL78/G15 is a 16MHz MCU with 4kB or 8kB code Flash, 1kB SRAM, and 1kB data Flash. The red fonts indicate changes from the RL78/G12, out of which, there are seven features removed in RL78/G15 to deliver a more cost-competitive MCU. Nevertheless, important functions such as serial communication, analog, and timers are retained in RL78/G15.
