It integrates a 17-channel 12-bit ADC and a single 12-bit DAC, plus peripherals including DMA, I²S, LVD, POR, PWM, and WDT. The part supports USB OTG alongside EBI/EMI, I²C, SPI, and UART/USART connectivity. With an operating temperature range of -40°C to 105°C and a supply range of 1.71 V to 3.6 V, it is suited for industrial control, motor drives, and outdoor telecom equipment where the board sees extended thermal cycling and single-cell battery or 3.3 V rail operation. ## USB OTG — host or device on one port The USB OTG controller lets this MCU act as either a USB host or peripheral without an external PHY or host-controller IC. That saves a chip and simplifies the BOM for designs that need to talk to a USB flash drive (host mode) or connect to a PC for firmware updates (device mode). The 50 MHz core has enough headroom to handle USB full-speed (12 Mbps) packet processing alongside the application code. ## Industrial temperature grade — no derating needed for the factory floor Rated -40°C to 105°C, this MCU can sit in an outdoor telecom cabinet or a motor-drive enclosure without active cooling or a heater. The wide supply range (1.71 V to 3.6 V) also means it keeps running through a battery droop from 3.6 V down to near 1.8 V — useful for portable or battery-backed instrumentation. ## Package and footprint — 64-LQFP with 48 I/O Housed in a 64-LQFP (10x10 mm) with 48 general-purpose I/O lines. The LQFP is a standard surface-mount package that routes easily on a two-layer board. The exposed paddle (if present) should be connected to ground with a via array under the package for thermal relief — the datasheet margin note applies: MSL 3 out of the bag, so bake before reflow if the moisture-barrier bag has been open past the floor-life window. ## Lifecycle and sourcing status The MCF51JU128VLH is listed as Active and RoHS3 compliant.","metaTitle":"NXP MCF51JU128VLH ColdFire V1 MCU, 50 MHz, 128 KB Flash","metaDescription":"NXP MCF51JU128VLH 32-bit ColdFire V1 MCU: 50 MHz core, 128 KB Flash, 32K x 8 RAM, USB OTG, 17-ch 12-bit ADC, -40°C to 105°C.
