It carries 768 KB of flash program memory, 48 KB of SRAM, and 8 KB of dedicated data EEPROM on a single die — enough headroom for a sensor-fusion or HMI firmware image without external memory. ## Peripheral set and analog front-end The ADC block is configurable as 12 channels of 8-bit, 10-bit, or 12-bit resolution, plus two 8-bit DAC outputs. For a multi-sensor node reading temperature, pressure, and proximity on separate analog inputs, the 12-channel count leaves margin for future channels without a board spin. Serial connectivity covers CSI (clocked serial interface), I²C, LINbus, SPI, and UART/USART — enough bus types to talk to common sensor modules, motor drivers, and display controllers without external protocol translators. ## Package, I/O, and board-fit Housed in a 64-LQFP (also listed as 64-LFQFP, 10x10 mm body), the part exposes 54 general-purpose I/O. Surface-mount only — the LQFP footprint fans out on two or four layers depending on how many peripheral signals you route. The internal oscillator means you can skip an external crystal for non-timing-critical applications, though the clock tree also accepts an external resonator. ## Active lifecycle and sourcing posture The RL78/G23 family is Renesas' current-generation low-power 16-bit line, positioned between the economy G1x series and the automotive F2x line. No pin-compatible second-source from another vendor exists, but the family itself shares a common peripheral set and toolchain across flash densities.","metaTitle":"R7F100GLN3CFB#AA0 Renesas RL78/G23 16-bit MCU, 32 MHz","metaDescription":"Renesas R7F100GLN3CFB#AA0 RL78/G23 16-bit MCU: 32 MHz core, 768 KB flash, 48 KB RAM, 8 KB EEPROM, -40 to +105°C, 64-LQFP.

The key difference is I/O count: the GMN variant offers 70 I/O in a 80-pin package, while the GLN has 54 I/O in a 64-pin package. A board laid out for the 80-pin GMN will not accept the 64-pin GLN without a layout change."},{"question":"What is the speed of the R7F100GLN3CFB#AA0?","answer":"The core runs at 32 MHz maximum. This is the CPU clock ceiling for the 16-bit RL78 pipeline — the actual throughput depends on flash wait states and the instruction mix, but the core can sustain one instruction per clock on most single-cycle opcodes."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/renesas/R7F100GLN3CFBAA0","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/renesas/R7F100GLN3CFBAA0 when reusing this data.
