The part is part of the PIC XLP 32MX family, which means it balances performance with low-power operation for always-on or battery-backed systems. ## AEC-Q100 and 105°C — the thermal envelope for under-hood and industrial ## 256 KB Flash / 64 KB RAM — memory budget for control firmware 256 KB of Flash is enough for a full AUTOSAR or bare-metal motor-control stack with a bootloader. The 64 KB RAM supports DMA transfers and multiple buffered communication channels. The 10-channel 10-bit ADC handles analog sensor inputs like throttle position, current sense, or temperature feedback without an external ADC. ## 21 I/O and serial connectivity — fitting into a 28-pin package With 21 I/O pins in a 28-VQFN exposed-pad package, the pin count is tight. The connectivity set includes I²C, SPI, UART, LIN, and IrDA — enough for CAN bridge, LIN slave, or sensor fusion nodes.","metaTitle":"Microchip PIC32MX174F256B-V/MM MCU, 72MHz, 256KB Flash","metaDescription":"Microchip PIC32MX174F256B-V/MM 32-bit MCU, MIPS32 M4K core at 72MHz, 256KB Flash, 64KB RAM, AEC-Q100 qualified for -40°C to 105°C.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q100, PIC® XLP™ 32MX","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Speed":"72MHz","Series":"Automotive, AEC-Q100, PIC® XLP™ 32MX","Package":"Tube","RAM Size":"64K x 8","Core Size":"32-Bit Single-Core","Peripherals":"Brown-out Detect/Reset, DMA, HLVD, I²S, POR, PWM, WDT","Connectivity":"I²C, IrDA, LINbus, PMP, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"21","Core Processor":"MIPS32® M4K™","Package / Case":"28-VQFN Exposed Pad","Data Converters":"A/D 10x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Program Memory Size":"256KB (256K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 105°C (TA)","Supplier Device Package":"28-QFN-S (6x6)","Voltage - Supply (Vcc/Vdd)":"2.5V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.34","priceTiers":[{"qty":1,"price":"$6.34000","currency":"USD"},{"qty":25,"price":"$5.81920","currency":"USD"},{"qty":100,"price":"$5.27850","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/406505dc0c6b8f400880e946b5d7da0d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/PIC32MX174F256B-V%2FMM/alternatives.json"},"ai":{"faq":[{"question":"What is the closest functional second-source for PIC32MX174F256B-V/MM?","answer":"The PIC32MX130F128L-I/PT is a peer in the PIC32MX family with the same MIPS32 M4K core, but it runs at 40 MHz, has 128 KB Flash, and comes in a 100-pin TQFP package.
