The 26-channel ADC (configurable to 8-, 10-, or 12-bit resolution) plus two 8-bit DAC channels cover multi-sensor analog front-ends without external muxing. ## 116 I/O in a 128-LQFP — dense enough for parallel displays or keypad matrices 116 general-purpose I/O in a 128-pin LQFP (14x20 mm body) means you can drive a parallel LCD, scan a 8x8 keypad matrix, and still have pins left for sensor interrupts and debug. ROHS3 compliant — no exemption-based restrictions on lead, mercury, or phthalates, so it passes EU and UKCA material declarations without a waiver. The 128-LQFP package is tray-packed; for reel or tape-and-reel quantities, confirm the packing option at RFQ.","metaTitle":"R7F100GSN3CFB#AA0 Renesas RL78/G23 MCU, 32MHz, 768KB Flash","metaDescription":"Renesas RL78/G23 16-bit MCU, 32MHz, 768KB flash, 48KB RAM, 116 I/O, -40°C to 105°C.
