That clock rate and memory budget fit control loops that need to sample sensors, run a PID, and push PWM updates within a few microseconds — think brushless DC motor commutation or a multi-axis joystick interface. ## Peripheral set — USB OTG, ADC, and PWM on a small footprint On-chip peripherals include a 9-channel 12-bit ADC and a 1-channel 12-bit DAC for analog signal chain, plus PWM, I²S, and a watchdog timer. The USB OTG controller handles host or device roles, and the EBI/EMI interface can connect external memory or a display controller. With 31 general-purpose I/O lines in a 44-pin MAPLGA package (5x5 mm), the pin count is tight but enough for a sensor hub or a human-machine interface with a small TFT.","metaTitle":"NXP MCF51JU64VHS MCU, ColdFire V1 32-bit, 50 MHz","metaDescription":"MCF51JU64VHS 32-bit MCU from NXP, ColdFire V1 core at 50 MHz, 64 KB Flash, 16 KB RAM, USB OTG, industrial temp -40 to +105 °C, 44-MAPLGA package.","metaKeywords":null},"attributes":{"series":"MCF51Jx","packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Speed":"50MHz","Series":"MCF51Jx","Package":"Bulk","RAM Size":"16K x 8","Core Size":"32-Bit Single-Core","Peripherals":"DMA, I²S, LVD, POR, PWM, WDT","Connectivity":"EBI/EMI, I²C, SPI, UART/USART, USB OTG","Mounting Type":"Surface Mount","Number of I/O":"31","Core Processor":"Coldfire V1","Package / Case":"44-VFLGA Exposed Pad","Data Converters":"A/D 9x12b; D/A 1x12b","Oscillator Type":"External","lifecycle_stage":"eol_hot","Program Memory Size":"64KB (64K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 105°C (TA)","Supplier Device Package":"44-MAPLGA (5x5)","Voltage - Supply (Vcc/Vdd)":"1.71V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.07","stockQuantity":16,"priceTiers":[{"qty":74,"price":"$4.07000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/c3b26de4fa090bd5c946ca398b3d661c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can the MCF51JU64VHS replace the MK51DX128CMC7 in an existing design?","answer":"No — the MK51DX128CMC7 is a different Kinetis K-series MCU with a 72 MHz ARM Cortex-M4 core, 128 KB Flash, and a different pinout.
