It carries 512 KB of program flash and 64 KB of RAM, plus an additional 8 KB of on-chip EEPROM — enough headroom for a moderate application stack without external memory. Packaged in a 64-LQFP (supplier package 64-LFQFP, 10x10 mm), it exposes 46 I/O lines. ## On-chip data converters and connectivity The ADC block provides 11 channels at 12-bit resolution; the DAC offers 2 channels at 12 bits. For serial interfaces, the part integrates I²C, SPI, SCI (UART), SSI, IrDA, and USB OTG — covering sensor readout, display links, and host communication on a single chip. ## Active production and compliance status The part carries an Active lifecycle status from Renesas. For new designs, the RX family offers a range of pin-compatible siblings with varying memory and peripheral mixes — the 64-LQFP footprint is shared across several RX100 and RX200 derivatives, though no direct pin-compatible replacement is listed as an official successor for this specific order code.","metaTitle":"R5F51138AGFM#3A Renesas RX MCU, 32MHz, 512KB Flash, 64-LQFP","metaDescription":"R5F51138AGFM#3A Renesas RX 32-bit MCU, 32 MHz, 512 KB Flash, 64 KB RAM, 8 KB EEPROM, -40 to 105°C, 64-LQFP.
