MCF51QU128VHS Présentation

The NXP Semiconductors MCF51QU128VHS is a 32-bit ColdFire V1 microcontroller with a 50 MHz core, 128 KB of Flash memory, and a 44-MAPBGA package measuring 5 mm by 5 mm. Its operating voltage is 1.71 V to 3.6 V, its Flash write-voltage range is also 1.71 V to 3.6 V, and its specified ambient-temperature range is -40°C to 105°C.

A microcontroller is a programmable semiconductor that integrates a processor core, memory, and peripherals into one device. The MCF51QU128VHS belongs to the ColdFire microcontroller hierarchy, combining a 32-bit MCU platform with configurable embedded EEPROM and FlexMemory technology. This places it between general-purpose embedded processing and the low-power, mixed-signal designs targeted by the MCF51Qx portfolio.

The principal features supported by the supplied data include an operating frequency of up to 50 MHz, 128 KB of Flash, configurable embedded EEPROM, and a high-accuracy 16-bit analog-to-digital converter. The small 5 mm by 5 mm package supports space-constrained designs, while the MCU family description emphasizes ultra-low-power capabilities. The NXP product result identifies the device as active.

The ColdFire V1 core provides the compute foundation, while the peripheral set is intended to support embedded control and signal-processing tasks. The datasheet result states that its general-purpose specifications apply to RGPIO, FTM, and UART signals under conditions of 25 pF loading, VDD from 3.6 V to 1.71 V, and the full temperature range.

Typical applications include industrial control, compact embedded instrumentation, low-power sensor nodes, portable measurement systems, and connected equipment requiring a small microcontroller footprint. The 50 MHz core provides processing headroom, while the 16-bit ADC is useful for monitoring analog inputs without requiring a separate converter.

The primary design consideration is package and firmware verification: use the manufacturer datasheet for the complete 44-pin map, exposed-pad or thermal requirements, decoupling recommendations, and startup configuration before layout or PCB replacement. A software migration is required unless the replacement is confirmed as pin-to-pin and function-compatible.

This page combines the verified NXP product information, datasheet specifications, source links, application guidance, and replacement constraints to support component selection and sourcing decisions beyond a basic distributor listing.

Notes de conception

Place all decoupling capacitors as close as practical to the MCF51QU128VHS supply pins and follow the NXP datasheet’s recommended values and layout. The verified operating range is 1.71 V to 3.6 V, so supply transients and ground return paths must be controlled. For the 44-MAPBGA package, use the manufacturer land pattern and assembly process requirements rather than a generic BGA footprint.

Treat thermal management as a package-design issue because the MCU is supplied in a compact 44-MAPBGA package. Follow the official package drawing for exposed-pad or thermal-via treatment and verify the final board’s thermal performance with the actual copper, solder mask, and enclosure. The supplied snippets do not provide thermal resistance or power dissipation values, so no numerical thermal estimate is asserted here.

Do not select a substitute solely because its memory size or CPU frequency is similar. Verify the complete 44-pin mapping, voltage limits, ADC characteristics, peripheral multiplexing, Flash organization, startup behavior, and software support. The supplied alternatives search did not establish a pin-to-pin equivalent, and similarly named MCF51 family members may require different firmware or board changes.

Use the datasheet’s stated 25 pF load condition when evaluating general-purpose signals such as RGPIO, FTM, and UART. Keep high-speed or externally accessible signal paths short, provide a continuous ground reference, and validate rise and fall times with the actual external load. The supplied data does not specify every GPIO timing parameter, so timing-dependent interfaces must be checked in the full datasheet.
