It packs 512 KB of Flash program memory, 48 KB of SRAM, and 8 KB of on-chip EEPROM, along with a 10-channel 12-bit ADC and a full set of peripherals including capacitive touch sensing, DMA, LVD, POR, PWM, and WDT. Connectivity covers I²C, LINbus, SCI, and SPI. The device operates from 1.8 V to 5.5 V over the industrial temperature range of -40°C to 105°C, making it suitable for factory automation, motor drives, outdoor telecom, and HMI panels that need touch-button interfaces without an external controller. ## Memory headroom and the EEPROM advantage The 512 KB Flash and 48 KB RAM place this MCU in the mid-range tier of the RX130 family — enough for a real-time control loop with a modest stack, a touch-sensing library, and a communication protocol stack. The 8 KB EEPROM is a genuine hardware EEPROM (not emulated in Flash), so calibration constants, configuration parameters, and production serial numbers can be written byte-by-byte without wear-leveling overhead or sector-erase delays. That saves a separate serial EEPROM on the BOM. ## Package and layout notes for the 48-WFQFN The device comes in a 48-WFQFN with an exposed pad (7x7 mm). The exposed pad must be soldered to a ground-plane via array for thermal relief. ## Lifecycle and sourcing R5F51308AGNE#20 carries an Active lifecycle status with ROHS3 compliance. No end-of-life notice or last-time-buy window is in effect, so it remains a safe choice for new designs and production builds.","metaTitle":"R5F51308AGNE#20 Renesas RX130 MCU, 32MHz, 512KB Flash","metaDescription":"R5F51308AGNE#20 Renesas RX130 32-bit MCU: 32 MHz core, 512 KB Flash, 48 KB RAM, 8 KB EEPROM, capacitive touch, -40°C to 105°C.
