Technical Details & Description

16-bit DSP/MCU for motor-control and industrial loops

The NXP MC56F8123VFBE is a 16-bit microcontroller built around the 56800E core, clocked at 40 MHz.

At 40 MHz, the 56800E core executes a single-cycle 16×16 multiply-accumulate.

Memory sizing — firmware fit and data buffer budget

The 32 KB Flash (organized as 16K x 16) holds the bootloader, main control firmware, and a modest lookup table for sine/cosine or SVPWM. The 8 KB of RAM is shared between data buffers, stack, and the ADC result registers.

Industrial temperature grade — deployment boundaries

Package and footprint — 64-LQFP 10x10 mm

Housed in a 64-lead LQFP with a 10x10 mm body, the MC56F8123VFBE fits a standard four-layer PCB.

NXP lists the MC56F8123VFBE as Active on the product status.

Frequently asked questions

What is the core processor of the MC56F8123VFBE?

The MC56F8123VFBE uses the 56800E 16-bit core, a DSP-optimized architecture with a single-cycle 16×16 MAC, running at 40 MHz.

What is the MC56F8123VFBE equivalent or second-source?

The NXP MK51DX128CMC7 is a 72 MHz ARM Cortex-M4 part in a different architecture family — not a pin-compatible or software-compatible substitute. For a true 56800E-family second source, consult the 56F8xxx series cross-reference; no direct second-source MPN is listed in the current record.
