It carries 192 KB of Flash program memory, 20 KB of RAM, and 8 KB of data EEPROM — enough for a moderate firmware image and local parameter storage without an external serial EEPROM. The 100-LQFP package (14x14 mm) brings out 88 general-purpose I/O lines, making it a fit for systems that need a mix of digital I/O, analog sensing, and serial communication on a single chip. ## Peripheral set and analog integration On-chip peripherals include a capacitive touch sensing unit, low-voltage detect (LVD), power-on reset (POR), PWM timers, and a watchdog timer (WDT). For serial communication the MCU supports CSI, I²C, LINbus, SPI, and UART/USART interfaces — enough to talk to sensors, displays, and actuators without external protocol converters. The analog subsystem provides 20 channels of 10-bit ADC, 8 channels of 12-bit ADC, and two channels of 8-bit DAC, covering most sensor-conditioning and control-loop feedback needs in a single device. ## Supply range and temperature grade The operating supply range spans 1.8 V to 5.5 V. The -40°C to 105°C temperature rating qualifies the part for industrial environments. ## Lifecycle and compliance Renesas lists the R7F100GPH3CFB#AA0 as Active, so there is no last-time-buy risk for current production. The part is ROHS3 compliant, which covers the European RoHS directive without exemptions. ## Memory sizing and firmware strategy The 192 KB Flash is organized as 192K x 8 bits, and the 8 KB EEPROM is separate from the Flash — useful for calibration constants or configuration data that need frequent updates without wearing the program memory. The 20 KB RAM (20K x 8) is adequate for moderate-size buffers and real-time data logging. For firmware that exceeds this footprint, the RL78/G23 family offers higher-density options in the same 100-LQFP footprint. ## Second-source and BOM flexibility The closest functional peer is the R7F100GPG3CFB#AA0, which shares the same 100-LQFP package, 88 I/O, peripheral set, and 32 MHz speed. The difference is memory — the GP variant carries less Flash and RAM. If the firmware fits the smaller memory, the GP part offers a drop-in BOM alternative for cost optimization or supply diversification without a board respin.","metaTitle":"R7F100GPH3CFB#AA0 Renesas RL78/G23 16-bit MCU, 32 MHz","metaDescription":"R7F100GPH3CFB#AA0 Renesas RL78/G23 16-bit MCU, 32 MHz core, 192 KB Flash, 20 KB RAM, 8 KB EEPROM, 88 I/O, -40 to 105°C, 100-LQFP.
