Its defining feature is the mixed-resolution ADC array: six 12-bit SAR channels for general-purpose analog inputs plus twelve 24-bit sigma-delta channels that resolve microvolt-level signals from bridge sensors, thermocouples, or load cells without an external AFE. The on-chip memory partition — 128 KB flash for program storage, 16 KB RAM for runtime data, and a separate 8 KB EEPROM block for calibration constants or configuration parameters — lets a sensor-fusion firmware image keep its non-volatile look-up tables in dedicated space without wearing the main flash. ## Connectivity and peripheral set for industrial buses The peripheral set includes CANbus for industrial network integration, plus I²C, SCI (UART), and SPI for local sensor buses. The DMA controller moves ADC results to RAM without core intervention, and the LVD and POR blocks handle brown-out supervision without an external supervisor IC.","metaTitle":"R5F523E5SDFL#10 Renesas RX23E-A MCU, 32MHz, 128KB Flash","metaDescription":"R5F523E5SDFL#10 Renesas RX23E-A 32-bit MCU, RXv2 core at 32MHz, 128KB flash, 16KB RAM, 8KB EEPROM, sigma-delta ADC array, 48-LQFP.","metaKeywords":null},"attributes":{"series":"RX23E-A","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Speed":"32MHz","Series":"RX23E-A","Package":"Tray","RAM Size":"16K 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":"128KB (128K 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":"$7.97","stockQuantity":23,"priceTiers":[{"qty":1,"price":"$7.97000","currency":"USD"},{"qty":10,"price":"$7.33600","currency":"USD"},{"qty":25,"price":"$7.18360","currency":"USD"},{"qty":40,"price":"$7.15875","currency":"USD"},{"qty":80,"price":"$6.42350","currency":"USD"},{"qty":230,"price":"$6.22939","currency":"USD"},{"qty":440,"price":"$5.92370","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/b96b13231d18733552f5d9cc9306443e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest functional alternative to R5F523E5SDFL#10?","answer":"It drops into the same PCB footprint without rewiring — the only difference is the extended temperature grade."},{"question":"What compliance documentation does Renesas provide for R5F523E5SDFL#10?","answer":"The part is ROHS3 compliant per the manufacturer's declaration.
