It packs 256 KB of Flash, 32 K x 8 of RAM, and 8 K x 8 of EEPROM — enough for a moderate firmware image with calibration data stored on-chip. ## The 24-bit sigma-delta ADC array — why it matters Twelve 24-bit sigma-delta converters is an unusual count for an MCU in this package. Most 48-pin MCUs offer a handful of 12-bit SAR channels. Here, you get a full differential measurement front-end that can handle multiple strain-gauge bridges or thermocouple inputs simultaneously. The six 12-bit SAR channels cover the faster, lower-resolution tasks — current sensing, voltage monitoring — while the sigma-delta channels handle the precision path. This split saves an external multiplexer and a separate ADC IC on the BOM. ## Temperature range and supply — industrial ready The 48-LQFP (7x7 mm LFQFP) package is hand-solderable with a fine tip and a steady hand — no BGA rework station needed. ## Peripherals and connectivity On the digital side, you get DMA, LVD, POR, PWM, and WDT — the usual complement for a motor-control or sensor-fusion design. Connectivity includes CANbus, I²C, SCI (UART), and SPI. Sixteen I/O pins in the 48-LQFP package means most of the pins are shared with the analog and serial interfaces, so plan the pin allocation early. The oscillator can be external or internal, which helps when board space is tight. ## Lifecycle and sourcing Renesas lists this part as Active with a current lifecycle stage. It is RoHS3 compliant.","metaTitle":"R5F523E6SGFL#10 Renesas RX23E-A MCU, 32-bit RXv2","metaDescription":"R5F523E6SGFL#10 is a 32-bit RXv2 MCU with 256KB Flash, 32KB RAM, 8KB EEPROM, and 12x24-bit sigma-delta ADCs.
