G15 has 8-pin to 20-pin packages, and 4kB to 8kB ROM. The 8-pin package is the smallest and first package in the RL78 family. RL78/G15 will meet the recent 8-bit microcontroller market demand for small-pin packages. The second feature is the maximum +125°C operating temperature. With the ability to support up to +125°C, RL78/G15 can be placed closer to heat generating products such as a motor, to reduce board space. The wide variety of package lineups and high-temperature compatibility make RL78/G15 suitable for a wide range of applications. In addition, a high-precision oscillator can reduce system BOM cost because there is no need for an external oscillator. RL78/G15 also has debugging, self-programming, and data Flash functions enabling the RL78/G15 to meet the market needs for 8-bit MCUs.
