It packs 256 KB of Flash program memory, 32K x 8 of RAM, and 8K x 8 of EEPROM — enough for moderate sensor-fusion algorithms and calibration tables. The standout feature is the dual ADC block: six 12-bit successive-approximation channels for general-purpose analog inputs, plus twelve 24-bit sigma-delta channels for high-resolution measurements like strain gauge, thermocouple, or load-cell readouts. This combination makes the part a natural fit for precision instrumentation, weigh scales, pressure transmitters, and industrial sensor nodes where you need both a control MCU and a precision analog front-end in one package. The supply range spans 1.8 V to 5.5 V. Operating temperature is -40°C to 85°C, suitable for industrial environments and outdoor enclosures. The 48-LQFP package (7x7 mm body) keeps the board footprint compact, with 16 I/O lines accessible for digital control and communication. ## CAN bus and serial connectivity for networked control The R5F523E6SDFL#10 includes a CANbus interface alongside I²C, SCI (UART), and SPI peripherals. This makes it straightforward to integrate into a CAN-based industrial network — think actuator control, sensor hubs, or distributed I/O nodes — while keeping a serial debug or configuration channel open. The DMA controller and PWM timer support efficient data movement and waveform generation without loading the core. ## Active lifecycle — no LTB risk for new designs Renesas lists the R5F523E6SDFL#10 as Active with ROHS3 compliance. There is no end-of-life notice or last-time-buy window on this part, so it is safe to qualify into a production BOM today. The RX23E-A series is a current product line, and Renesas continues to support it with documentation and tools. ## What the 24-bit sigma-delta ADC means for the BOM The twelve 24-bit sigma-delta ADC channels eliminate the need for an external precision ADC or instrumentation amplifier in many sensor applications. For a weigh-scale or pressure-transmitter design, the MCU directly reads the bridge output at 24-bit resolution, handles the digital filtering, and communicates the result over CAN or I²C. This integration saves board space, reduces component count, and simplifies the supply chain — one MCU instead of an MCU plus a separate ADC plus a reference. The 12-bit SAR ADC handles faster, lower-resolution tasks like monitoring supply rails or temperature diodes.","metaTitle":"R5F523E6SDFL#10 Renesas RX23E-A MCU, 32 MHz, 256KB Flash","metaDescription":"R5F523E6SDFL#10 Renesas RX23E-A 32-bit MCU with RXv2 core at 32 MHz, 256KB Flash, 32K x 8 RAM, 8K x 8 EEPROM, dual ADC (6x12b + 12x24b sigma-delta), CANbus","metaKeywords":null},"attributes":{"series":"RX23E-A","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Speed":"32MHz","Series":"RX23E-A","Package":"Tray","RAM Size":"32K x 8","Core Size":"32-Bit","EEPROM Size":"8K x 8","Peripherals":"DMA, LVD, POR, PWM, WDT","Connectivity":"CANbus, I²C, SCI, SPI","Mounting Type":"Surface Mount","Number of I/O":"16","Core Processor":"RXv2","Package / Case":"48-LQFP","Data Converters":"A/D 6x12b, 12x24b Sigma-Delta","Oscillator Type":"External, Internal","lifecycle_stage":"eol_hot","Program Memory Size":"256KB (256K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"48-LFQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.44","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$8.44000","currency":"USD"},{"qty":10,"price":"$7.76700","currency":"USD"},{"qty":25,"price":"$7.60520","currency":"USD"},{"qty":40,"price":"$7.57900","currency":"USD"},{"qty":80,"price":"$6.80050","currency":"USD"},{"qty":230,"price":"$6.59496","currency":"USD"},{"qty":440,"price":"$6.27132","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/b96b13231d18733552f5d9cc9306443e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does R5F523E6SDFL#10 support CAN bus?","answer":"Yes, the R5F523E6SDFL#10 includes a CANbus interface as one of its connectivity peripherals, alongside I²C, SCI, and SPI."},{"question":"What is the maximum operating frequency of R5F523E6SDFL#10?","answer":"The RXv2 core runs at 32 MHz, which is the maximum operating frequency for this device."},{"question":"What are the equivalents to R5F523E6SDFL#10?","answer":"Within the RX23E-A series, the R5F523E5AGFL#10 is a close sibling — same core, same peripherals, same 32 MHz speed, same 48-LQFP package, but with an extended temperature range of -40°C to 105°C.
