It carries 768 KB of Flash program memory, 48 KB of RAM, and 8 KB of EEPROM, all on-chip. The peripheral set includes capacitive touch sensing, a 12-bit ADC with up to 10 channels, a dual 8-bit DAC, and serial interfaces covering CSI, I²C, LINbus, SPI, and UART/USART. Operating from 1.6 V to 5.5 V over -40°C to 85°C, it targets industrial control, building automation, and HMI panels that need a single-chip sensor-and-actuator controller. ## 32 MHz core and memory sizing for the BOM The 32 MHz clock is the RL78 core's rated speed — enough for real-time control loops and protocol handling without an external oscillator, since the internal oscillator is the default clock source. The 768 KB Flash holds a full application stack plus a bootloader; 48 KB RAM supports moderate data buffering and RTOS task stacks. The 8 KB EEPROM is a separate data Flash array for calibration constants and configuration parameters that survive resets — no external serial EEPROM needed, which saves a BOM line and board area. ## Supply range and temperature grade — what they mean for fit A supply range of 1.6 V to 5.5 V means this MCU runs directly from a single Li-ion cell (down to its discharge floor) or a 5 V industrial rail without a separate LDO. The -40°C to 85°C industrial temperature grade qualifies it for outdoor telecom cabinets, factory-floor motor drives, and automotive cabin modules — not under-hood, but fine for interior and chassis-domain applications. ## Active lifecycle — no LTB risk The R7F100GFN2DFP#AA0 carries an Active lifecycle status and is ROHS3 compliant. There is no end-of-life notice, no last-time-buy window, and no successor part to track. This part is qualified for new designs and production ramp without obsolescence risk.","metaTitle":"R7F100GFN2DFP#AA0 RL78/G23 16-bit MCU, 32 MHz, 768 KB Flash","metaDescription":"R7F100GFN2DFP#AA0 from Renesas: RL78/G23 16-bit MCU at 32 MHz, 768 KB Flash, 48 KB RAM, 8 KB EEPROM, 44-LQFP, -40 to 85°C, active production, ROHS3.","metaKeywords":null},"attributes":{"series":"RL78/G23","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Speed":"32MHz","Series":"RL78/G23","Package":"Tray","RAM Size":"48K x 8","Core Size":"16-Bit","EEPROM Size":"8K x 8","Peripherals":"Capacitive Touch, LVD, POR, PWM, WDT","Connectivity":"CSI, I²C, LINbus, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"37","Core Processor":"RL78","Package / Case":"44-LQFP","Data Converters":"A/D 10x8/10b/12b; D/A 2x8b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Program Memory Size":"768KB (768K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"44-LQFP (10x10)","Voltage - Supply (Vcc/Vdd)":"1.6V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.44","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$4.44000","currency":"USD"},{"qty":10,"price":"$4.02600","currency":"USD"},{"qty":25,"price":"$3.93840","currency":"USD"},{"qty":40,"price":"$3.91700","currency":"USD"},{"qty":160,"price":"$3.51206","currency":"USD"},{"qty":320,"price":"$3.49928","currency":"USD"},{"qty":480,"price":"$3.37140","currency":"USD"},{"qty":960,"price":"$3.20518","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/a2871ad707206e40f405bbcc37178bf9.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the maximum clock speed of R7F100GFN2DFP#AA0?","answer":"The RL78 core runs at 32 MHz, which is the rated maximum speed.
