The 8 KB EEPROM holds calibration coefficients and fault logs without an external serial EEPROM. The 32 MHz RXv2 core delivers about 165 DMIPS at 32 MHz from flash with zero-wait up to 32 MHz — the throughput ceiling is the flash wait-state profile, not the core clock. For a 1 kHz sensor read loop with a 24-bit filter settling time of a few milliseconds, the core idles most of the cycle. ## Supply, temperature, and package Mounting is surface-mount only. Sourced per RFQ through independent distribution. ## Peripheral set and I/O budget Connectivity includes CANbus, I²C, SCI (UART), and SPI — a typical sensor node needs one I²C for a digital sensor and one SPI for an external ADC or display; the remaining two can serve a debug UART and a CAN bus for field data upload. Only 16 I/O are available, so every pin allocation must be deliberate — a full CAN + UART + I²C + SPI configuration leaves about 8 GPIOs for buttons, LEDs, and interrupts. On-chip peripherals include DMA, LVD (low-voltage detect), POR (power-on reset), PWM, and WDT. The DMA can service the sigma-delta ADC results without CPU intervention, keeping the core free for higher-level processing. Oscillator options are external crystal or internal RC — the internal oscillator is accurate enough for UART and CAN at room temperature, but a precision external crystal is recommended for the sigma-delta ADC's sampling clock to avoid drift.","metaTitle":"R5F523E5SGFL#30 Renesas RX23E-A 32-bit MCU, 32 MHz","metaDescription":"R5F523E5SGFL#30 Renesas RX23E-A 32-bit MCU, 32 MHz, 128 KB Flash, 16 KB RAM, 8 KB EEPROM, 12x24b sigma-delta ADC, -40 to 105 °C, 48-LFQFP.","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 ~ 105°C (TA)","Supplier Device Package":"48-LFQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.54","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$8.54000","currency":"USD"},{"qty":10,"price":"$7.85700","currency":"USD"},{"qty":25,"price":"$7.69280","currency":"USD"},{"qty":40,"price":"$7.66650","currency":"USD"},{"qty":80,"price":"$6.87900","currency":"USD"},{"qty":250,"price":"$6.67108","currency":"USD"},{"qty":500,"price":"$6.34372","currency":"USD"},{"qty":1000,"price":"$6.12254","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/b96b13231d18733552f5d9cc9306443e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest functional second-source for R5F523E5SGFL#30?","answer":"The R5F523E5AGFL#10 is the closest peer in the same RX23E-A family — same RXv2 core, same 32 MHz speed, same 48-LFQFP package, same peripheral set including the sigma-delta ADC.
