Product details

50 MHz ColdFire V1 core with 64 KB flash

The MCF51QU64VHS is a 32-bit single-core MCU built around the ColdFire V1 core, clocked at 50 MHz. With 64 KB of on-chip flash program memory and 16 KB of RAM, it handles moderate firmware footprints — control loops, data logging, or protocol stacks — without external memory.

Analog and connectivity peripherals

Connectivity spans EBI/EMI for parallel memory or displays, plus I²C, SPI, and UART/USART for serial sensors, actuators, and debug links. Peripheral set includes DMA for autonomous data movement, LVD for brown-out detection, POR for clean power-on reset, PWM for motor or LED drive, and a watchdog timer for system supervision.

Supplied in a 44-VFLGA exposed-pad package (44-MAPLGA, 5x5 mm).

Frequently asked questions

Will MCF51QU64VHS drop into a board designed for MK51DX128CMC7?

No — the MK51DX128CMC7 is a different MCU family (Kinetis K) with 72 MHz core and different pinout. The MCF51QU64VHS uses the ColdFire V1 core in a 44-MAPLGA package; a board spin is required for a direct replacement.
