Product details
Overview
MCF51JE128VMB from NXP Semiconductors (formerly Freescale) is a 32-bit ColdFire V1 microcontroller featuring a 128 KB Flash memory, 32 KB RAM, and integrated USB OTG, dual SCI, dual SPI, I²C, 12-bit ADC, 12-bit DAC, programmable analog comparator (PRACMP), and Time-of-Day (TOD) timer - designed for low-power industrial control, remote sensing, and embedded USB host/device applications operating across –40°C to 105°C.
For engineers reviewing the MCF51JE128VMB datasheet, MCF51JE128VMB pinout, MCF51JE128VMB application, or MCF51JE128VMB equivalent, key selection criteria include its 80-pin LQFP package with Mini-FlexBus interface, ultra-low-power stop3 mode with 6 µs wake-up, ColdFire ISA_C instruction set, and on-chip 3.3 V USB regulator enabling cost-effective USB connectivity without external power management.
Technical Context
The MCF51JE128VMB implements the ColdFire V1 CPU core with MAC support for signed/unsigned integer and fractional arithmetic, and uses the Multipurpose Clock Generator (MCG) with PLL/FLL to scale system clock up to 50.33 MHz at >2.4 V. Its memory subsystem includes two independent Flash arrays enabling background programming during interrupt execution.
Peripherals are tightly integrated via the System Integration Module (SIM): the PDB triggers ADC sampling sequences with periodic interrupts; PRACMP operates in stop3 mode; and the dual-role USB OTG controller includes on-die transceiver and 3.3 V regulator compliant with USB 2.0 specification for control, bulk, interrupt, and isochronous transfers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Kinetis K22F51212 | ARM Cortex-M4F core, 120 MHz max, 512 KB Flash, no integrated USB PHY - requires external USB transceiver. | Lacks on-chip USB transceiver and 3.3 V regulator; higher performance but larger code footprint and power draw in active mode. | Choose when needing floating-point math or Ethernet connectivity; avoid if minimizing BOM cost and layout complexity is critical. |
| MCF51JM128VFB | Same ColdFire V1 core and peripheral set, but in 64-pin QFP package with reduced I/O (47 GPIO vs 65) and no Mini-FlexBus. | Cannot interface with external memory or complex peripherals; limited to self-contained applications without expansion. | Choose only for space-constrained designs where Mini-FlexBus and full GPIO count are unnecessary. |
Compared with K22F51212 and MCF51JM128VFB, the MCF51JE128VMB uniquely balances USB integration, low-power stop modes, and external memory expansion - making it optimal for cost-sensitive, battery-aware, USB-connected embedded systems requiring field-upgradable firmware and analog I/O.

FAQ
What is the maximum operating frequency of the MCF51JE128VMB?
The MCF51JE128VMB achieves up to 50.33 MHz at supply voltages above 2.4 V and ambient temperatures from –40°C to 105°C. At 2.1 V, it operates up to 40 MHz, and at 1.8 V, up to 20 MHz - enabling dynamic voltage/frequency scaling for power optimization in battery-powered MCF51JE128VMB deployments.
Does the MCF51JE128VMB support USB host functionality?
Yes, the MCF51JE128VMB implements USB On-The-Go (OTG), allowing it to operate in device, host, or dual-role mode. Its integrated transceiver and 3.3 V regulator enable direct connection to USB peripherals like flash drives or keyboards without external components - a key capability confirmed in the MCF51JE128VMB datasheet Section 1.
How many analog input channels does the MCF51JE128VMB ADC support?
The MCF51JE128VMB features a 12-bit SAR ADC with up to 12 single-ended input channels (ADP[11:0]), plus internal bandgap reference channel. It operates across the full supply range (1.8 V to 3.6 V) and remains functional in stop3 mode - enabling continuous low-power sensor monitoring in the MCF51JE128VMB.
What debug interface does the MCF51JE128VMB use?
The MCF51JE128VMB uses the ColdFire DEBUG_Rev_B+ interface with single-wire Background Debug Mode (BDM) via the PTD0/BKGD/MS pin. This provides real-time debugging, flash programming, and 6 hardware breakpoints - all supported natively by CodeWarrior and modern GDB-based toolchains for the MCF51JE128VMB.
Is the MCF51JE128VMB pin-compatible with the MCF51JE256 series?
No - the MCF51JE128VMB uses an 80-pin LQFP package, while the MCF51JE256 variants are offered in 80-, 81-, 100-, and 104-pin packages with differing pinouts and peripheral mappings. Although both share the same ColdFire V1 core and peripheral IP, the MCF51JE128VMB pin assignment is specific to its 80-LQFP configuration and not interchangeable with MCF51JE256 variants.
