The 512 KB program flash (512K x 8) and 48 KB RAM (48K x 8) provide enough headroom for a control-loop stack, a communication protocol buffer, and a modest data-logging array, while the 8 KB on-chip EEPROM (8K x 8) holds calibration constants and configuration parameters without requiring an external serial EEPROM. The 128-LQFP package (: 128-LFQFP 14x20 mm) exposes 116 I/O lines — enough to interface a parallel LCD, a keypad matrix, and a handful of sensors and actuators without multiplexing on the board. The 0.5 mm pitch of the LQFP demands a 4-layer PCB for clean fan-out of the outer rows; a 2-layer board will struggle with the centre power and ground pins. ## 26-channel ADC and dual DAC — the analog front-end for multi-sensor systems The data-converter block integrates a 26-channel ADC with selectable 8-, 10-, or 12-bit resolution and a dual 8-bit DAC. The dual DAC can drive two analogue outputs — a setpoint voltage and a monitoring signal, for instance — without external DAC chips. ## Active lifecycle, ROHS3, and the I/O count trade-off against the 88-pin sibling The RL78/G23 series is Renesas' current-generation low-power 16-bit family, positioned for cost-sensitive HMI, appliance, and industrial-control applications.","metaTitle":"R7F100GSL3CFB#AA0 Renesas RL78/G23 MCU, 32 MHz, 512 KB Flash","metaDescription":"R7F100GSL3CFB#AA0 Renesas RL78/G23 16-bit MCU: 32 MHz core, 512 KB flash, 48 KB RAM, 8 KB EEPROM, 116 I/O, 128-LQFP.
