The 8-channel 8/10-bit ADC covers basic analog sensing (temperature, pressure, light level) without an external converter. On-chip POR and WDT eliminate the external supervisor IC, saving board space and cost. The internal oscillator removes the crystal and its load caps — the MCU runs standalone with just a decoupling cap and the supply rail. ## Package and board integration for space-limited layouts The 16 GPIOs are enough for a few sensor inputs, a small keypad matrix, or driving a simple LED display — but plan the pin allocation before layout because there is no room for rework on a 0.65 mm pitch. Surface-mount only — no through-hole variant exists.","metaTitle":"R5F11W67ASM#10 Renesas RL78/G1M MCU, 20MHz, 4KB Flash","metaDescription":"R5F11W67ASM#10 Renesas 16-bit MCU, RL78/G1M series, 20MHz, 4KB flash, 512B RAM, 20-TSSOP.
