The commercial -I suffix part (PIC32MX154F128B-I/SO) is only rated to 85°C, so if your BOM calls for the -V, don't substitute the -I without a thermal analysis — the silicon is the same, but the test and screening flow is different. ## 28-SOIC — rework and footprint realities The 28-SOIC (7.50 mm body width) is a rework-friendly package — the gull-wing leads are visible for inspection and the 1.27 mm pitch gives you room to route traces between pads on a two-layer board. The 21 I/O count means you're not breaking out every peripheral simultaneously — plan your pin mux allocation early, because the I²S and PWM functions share pins with the UART and SPI modules. ## Peripheral set — what's on the bus On-chip peripherals include Brown-out Detect/Reset, DMA, HLVD (High/Low Voltage Detect), I²S, POR, PWM, and WDT. Connectivity covers I²C, IrDA, LINbus, PMP, SPI, and UART/USART. The 10-channel 10-bit ADC is adequate for reading analog sensors like thermistors or potentiometers, but if you need 12-bit resolution or more channels, you'll be looking at the PIC32MX130F128L variant with its 48-channel ADC.","metaTitle":"PIC32MX154F128B-V/SO MCU, 72 MHz, 128KB Flash, AEC-Q100","metaDescription":"Microchip PIC32MX154F128B-V/SO 32-bit MIPS32 M4K MCU, 72 MHz, 128KB Flash, 32K x 8 RAM, AEC-Q100 qualified, -40°C to 105°C, 28-SOIC.","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":"32K 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-SOIC (0.295\\\", 7.50mm Width)","Data Converters":"A/D 10x10b","Oscillator Type":"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":"28-SOIC","Voltage - Supply (Vcc/Vdd)":"2.5V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.04","priceTiers":[{"qty":1,"price":"$6.04000","currency":"USD"},{"qty":25,"price":"$5.54320","currency":"USD"},{"qty":100,"price":"$5.01400","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/406505dc0c6b8f400880e946b5d7da0d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/PIC32MX154F128B-V%2FSO/alternatives.json"},"ai":{"faq":[{"question":"What is the maximum clock speed of PIC32MX154F128B-V/SO?","answer":"The MIPS32 M4K core runs at 72 MHz.
