The supply range goes down to 1.6 V, which suits battery-powered or energy-harvesting sensor nodes where every millivolt of headroom matters. ## On-chip analog and touch — what it saves on the BOM This MCU integrates a 10-channel ADC that can be configured for 8-, 10-, or 12-bit resolution, plus two 8-bit DAC outputs. That means a single-chip solution for reading multiple analog sensors (thermistors, potentiometers, current shunts) and generating analog reference or control voltages without external converters. The capacitive touch sensing peripheral is a genuine BOM eliminator for membrane-button or proximity interfaces in white goods, appliances, and control panels. ## Serial interfaces for fieldbus and sensor links Connectivity covers CSI (clocked serial interface), I²C, LINbus, SPI, and UART/USART. The LINbus support makes this a candidate for automotive body electronics (door modules, seat controllers, lighting nodes) where a LIN slave is needed. The I²C and SPI ports handle local sensor hubs, EEPROM, or display drivers. With 37 I/Os available, you can keep a parallel LCD or a keypad matrix without a port expander. Renesas lists the R7F100GFF2DFP#HA0 as Active. No urgency to qualify a second source today, though the RL78/G23 family has several pin-compatible siblings if you need more I/O or a wider temperature range later. ## Temperature grade and environment If your design lives under the hood or near an engine block, step up to the RL78/G23 variant with the extended temperature option.","metaTitle":"Renesas R7F100GFF2DFP#HA0 RL78/G23 16-bit MCU, 96KB Flash","metaDescription":"Renesas R7F100GFF2DFP#HA0 RL78/G23 16-bit MCU, 32 MHz, 96KB Flash, 44-LQFP, -40°C to 85°C.
