MCF51JE128VLK Übersicht

The NXP (formerly Freescale) MCF51JE128VLK is a Coldfire V1 MCF51JE series 32-bit microcontroller IC running at 50 MHz, with 128 KB of embedded Flash program memory (128K x 8) housed in an 80-pin LQFP (VLK) package measuring 12 x 12 mm. The part is built on a Coldfire V1 Harvard architecture core with integrated rich connectivity peripherals including CANbus, EBI/EMI, I2C, SCI, SPI and USB OTG.

A microcontroller is a single-chip processor that integrates a CPU core, program memory (Flash), data memory (RAM), and a mix of on-chip peripherals (timers, communication controllers, ADCs, GPIO). Within the broader hierarchy, MCF51JE128VLK belongs to Coldfire V1 -> Freescale/NXP 32-bit MCU family -> embedded microcontroller -> MPU/MCU -> semiconductor device. Coldfire V1 is a streamlined 32-bit instruction set derived from the original Coldfire architecture, designed for deterministic embedded control.

Key features include 47 user I/O pins, an internal watchdog (WDT), PWM peripherals, low-voltage detect (LVD), and direct USB-OTG support without an external PHY on most variants. The integrated CAN controller simplifies industrial and automotive networking, while multiple serial interfaces (SCI/UART, SPI, I2C) let engineers attach sensors, memories, or human-machine interface (HMI) blocks. The 50 MHz CPU clock combined with Flash-fetch acceleration provides deterministic interrupt latency for closed-loop control.

Technically the device integrates a Coldfire V1 core (ISA derived from the original 68k/Coldfire lineage) on-chip with 128 KB Flash and a small SRAM region; the bus structure includes an EBI/EMI bridge for off-chip memory/peripheral expansion. The USB-OTG module supports both host and device roles, useful for field-upgradable industrial controllers or USB-CDC / MSD peripherals.

Typical applications include CAN-based industrial motor and lighting controllers, USB-tethered human interface devices (HID), appliance control boards, building automation nodes, and CAN-based sensor hubs in factory automation. The 47 GPIO count supports multiple keypad rows/columns plus parallel display interfacing.

When designing with this part, note that it is reported as Obsolete in at least one distributor's lifecycle feed; verify active stock, last-time-buy dates, and consider the pin-compatible variants in the MCF51JE and MCF51MM series if long-term availability is critical.

Typische Anwendungen

MCF51JE128VLK ist geeignet für 7 Anwendungs: CAN-Based Industrial Lighting Controller, USB-Tethered Human Interface Device, Building Automation Sensor Hub, Appliance Main Control Board, CAN-Based Automotive Body Controller, USB-Connected Industrial Data Logger, Factory Automation I/O Module.

🏭

CAN-Based Industrial Lighting Controller

The MCF51JE128VLK fits industrial lighting controllers because its integrated CANbus and 50 MHz Coldfire V1 core provide deterministic network-based dimming control across many fixtures on a shared bus. The 47 GPIO drive multiple LED-driver channels and keypads, while USB OTG enables field firmware updates via a service tool. Compared to a Cortex-M0 part at the same price tier, this MCU consolidates CAN, USB and PWM peripherals in a single die, lowering BOM cost and PCB area in dimmable LED-driver hubs.

📱

USB-Tethered Human Interface Device

In USB-HID designs such as custom keyboards, barcode scanners, or POS terminals, the MCF51JE128VLK's integrated USB OTG controller reduces part count by removing the need for an external USB transceiver or PHY. The 128 KB Flash is sufficient for HID descriptor tables, scan/buffer logic, and on-device OAD (over-air download) routines, while the 47 GPIO support matrix key-scanning and indicator LEDs. This part is a strong fit when the design wants 32-bit throughput for USB-class firmware, not a Cortex upgrade path.

🧩

Building Automation Sensor Hub

The MCF51JE128VLK serves as a sensor hub in building-automation networks because it combines a 32-bit core for sensor fusion, I2C/SPI for digital sensors, and a CAN interface for backbone communication with HVAC controllers. The 128 KB Flash holds protocol stacks (Modbus, BACnet-to-CAN gateways) plus application code, and 47 GPIO are reserved for local I/O expansion. Compared to 8-bit MCUs, the Coldfire V1 delivers deterministic interrupt response for closed-loop climate control under heavy bus traffic.

⚡

Appliance Main Control Board

The MCF51JE128VLK's combination of PWM peripherals, watchdog timer, and low-voltage detect suits main-control boards for white goods such as washing machines and induction cookers. The 50 MHz core executes motor-control loops and HMI updates in real time, while the 47 GPIO drive relays, keypad matrices and 7-segment displays. A typical design pairs this MCU with an IGBT-driver gate board for variable-speed drives, where determinism and CAN diagnostics from the MCU simplify field service.

🚗

CAN-Based Automotive Body Controller

Inside a CAN-based body controller (door modules, seat controllers, lighting clusters), the MCF51JE128VLK acts as a low-cost node that aggregates switch inputs, drives LEDs, and forwards events on the CAN bus at 50 MHz Coldfire throughput. The Flash-based program storage allows field firmware updates over CAN or USB, reducing recall costs. Where the design mandates AEC-Q100 qualification, however, evaluate NXP's automotive-grade S12/Kinetis families instead of this part.

🖥️

USB-Connected Industrial Data Logger

For a portable industrial data logger, the MCF51JE128VLK pairs USB-OTG device mode (for file export to a USB stick) with the on-chip SCI/UART for sensor front-ends. The 128 KB Flash stores configuration and small log buffers while an external SPI Flash holds bulk history. The low-cost Coldfire V1 core provides real-time timestamping without requiring an RTOS; engineers also use the same VLK footprint across product variants to switch memory density at the last BOM step.

🏭

Factory Automation I/O Module

In a factory-automation I/O module the MCF51JE128VLK acts as the local intelligence for digital inputs, relay outputs, and CAN-bus uplink to a PLC. The 47 GPIO is split between input-isolators, relay coils, status LEDs and a configuration keypad; the Coldfire V1 core runs debounce, latching, and diagnostic firmware in a single loop. Compared to an 8-bit MCU, this part adds USB-OTG for laptop-based module configuration without needing an extra serial-to-USB bridge.

What is the MCF51JE128VLK?
The MCF51JE128VLK is a Coldfire V1 32-bit microcontroller from NXP (formerly Freescale) with 128 KB of Flash program memory. It runs at 50 MHz, supports 47 user I/O pins, and integrates CANbus, I2C, SCI, SPI, EBI/EMI, and USB OTG connectivity in an 80-pin LQFP (12x12 mm) package. It is intended for embedded control applications that require industrial networking and USB connectivity in a single IC.
Where can I buy the MCF51JE128VLK online?
The MCF51JE128VLK is currently visible at DigiKey, Mouser, Octopart, Hotenda, and YIC Electronics as of 2026-10-18. Authorized distributor stock is limited because at least one feed reports the part as Obsolete; budget distributor or franchised-broker stock (e.g. Rochester Electronics for the Freescale-branded variant) is the practical path. Engineering samples can be requested from NXP for qualified end-uses.
What is the price of the MCF51JE128VLK?
Authoritative distributor pricing for the MCF51JE128VLK as of 2026-10-18 ranges from approximately 11.50 USD at qty 1 down to 6.95 USD at qty 1000 on Octopart-aggregated distributor listings; however, because Obsolete parts often carry stock premiums, contact your distributor for a quote at larger volumes. Hotenda and YIC Electronics also publish indicative pricing but availability varies.
Is the MCF51JE128VLK in stock and what is the lead time?
Stock for the MCF51JE128VLK is currently constrained across authorized distributors because the part is flagged Obsolete on at least one feed; expected lead times run from immediate shipment of small reels from broker stock to 8-12 weeks if a manufacturer reorder is needed. Verify with DigiKey, Mouser, or Rochester Electronics at the time of order for the most accurate stock picture.
What is the difference between MCF51JE128VLK and MCF51JE256CLK?
Both parts belong to the NXP MCF51JE Coldfire V1 family, but the MCF51JE256CLK doubles Flash to 256 KB and uses a CLK-suffix LQFP/FBGA package, while the MCF51JE128VLK offers 128 KB Flash in an 80-LQFP (VLK). For 128 KB of Flash with full LQFP-80 footprint, the VLK variant is the correct choice. Where higher memory density is needed, the CLK variant is the migration path.
How does the MCF51JE128VLK compare to the MCF51MM128VLK?
Both parts share the same Coldfire V1 32-bit architecture, 80-pin LQFP (VLK) packaging, and 128 KB Flash. The MCF51MM128VLK is tuned for metering/measurement with enhanced analog and RTC features, whereas the MCF51JE128VLK emphasizes industrial connectivity including built-in USB OTG. For metering designs needing extra ADC precision, pick the MM; for USB/CAN-driven industrial nodes, pick the JE.
What is the best drop-in replacement for the MCF51JE128VLK?
The closest drop-in same-package replacement is the MCF51JE256VLK - same VLK (80-LQFP) footprint, same Coldfire V1 core at 50 MHz, but with 256 KB Flash. If stock of JE-series parts is exhausted, the MCF51MM128VLK offers the same 80-LQFP footprint and 128 KB Flash from a related family but with analog-focused peripherals - verify peripheral mapping before qualifying.
When should I choose the MCF51JE128VLK over the MCF51JE256CLK?
Choose the MCF51JE128VLK when your firmware fits inside 128 KB Flash and you need the standard 80-pin LQFP (VLK) footprint for an established PCB layout; the JE-128 variant is typically more available on the secondary market. Switch to the MCF51JE256CLK when firmware headroom is required (>128 KB code/data) or when the CLK package variant is accepted by your layout.
Can a later NXP Kinetis MCU replace the MCF51JE128VLK?
A Kinetis ARM Cortex-M MCU is not a drop-in replacement - it changes the core (ARM vs Coldfire), toolchain, and pinout, so a PCB redesign is mandatory. As an architectural migration, Kinetis offers modern peripherals and long-term support, but expect to re-port firmware and re-layout the board. Use Kinetis only when you can afford the redesign and want to leave the Coldfire ecosystem.
Where to download the MCF51JE128VLK datasheet PDF?
The official NXP MCF51JE128 datasheet PDF is available on the NXP website at the product documentation URL listed in our data sources. Third-party mirrors such as abc-semi.com also host a PDF copy, but the NXP-hosted file is authoritative for electrical characteristics and errata. Always cross-reference the latest revision notice before committing to a board spin.
Where can I find the MCF51JE128VLK pinout?
The pinout for the MCF51JE128VLK is published in the NXP MCF51JE128 datasheet, including signal multiplexing for CAN, SPI, I2C, USB OTG and the 47 GPIO pins. The 80-LQFP (VLK) package uses the standard JEDEC pin-1 indicator, and the pin description table in the datasheet provides each pin's primary and alternate functions. Refer to the package diagram section for the 12 x 12 mm body layout.
What is the operating temperature range of the MCF51JE128VLK?
The exact operating temperature range of the MCF51JE128VLK should be confirmed against the manufacturer datasheet, as the verified distributor feeds did not surface an explicit minimum/maximum value at this time. Industrial-grade Coldfire V1 parts from this family are commonly rated -40C to +85C or -40C to +105C, but treat that as a guideline until the datasheet is consulted.
Does the MCF51JE128VLK support USB OTG or only USB device?
The MCF51JE128VLK integrates a USB OTG controller that supports both USB host and USB device roles, with the appropriate external Mini-AB or Micro-AB receptacle. The OTG controller negotiates host/device role via the ID pin and supplies session-request/host-request signalling. For battery-powered USB device peripherals it can also operate in pure device mode using the on-chip transceiver.
Which debugging toolchain works with the MCF51JE128VLK?
NXP supports the Coldfire V1 family with CodeWarrior for Coldfire and P&E Micro hardware debuggers (USB-ML-CF), and open-source options such as GCC with the m68k/coldfire backend plus OpenOCD can interface the BDM port. Engineers targeting long-term toolchain stability should pin a specific CodeWarrior build and BDM firmware version because Coldfire V1 is in maintenance mode.
Is the MCF51JE128VLK RoHS compliant and lead-free?
The MCF51JE128VLK ships in an LQFP package with matte-tin plating and is consistent with RoHS-compliant, lead-free assembly processes; exact declarations of conformity are available in the NXP material declaration and the product environmental compliance page. For conflict-minerals reporting, NXP publishes an up-to-date CMRT under its corporate-responsibility program.

Wichtigste Unterscheidungsmerkmale

  • Doubles Flash without changing footprint (vs. MCF51JE256VLK)
  • Industrial-connectivity optimized vs metering/measurement (vs. MCF51MM128VLK)
  • More USB flexibility on the JE family (vs. MCF51JM128VLK)

Designhinweise

Place bypass capacitors (100 nF ceramic in parallel with 4.7 uF bulk) as close as possible to every VDD/VSS pair on the MCF51JE128VLK; the Coldfire V1 core draws sharp transient currents during Flash programming, and missing decoupling will cause Flash verify errors. Use a star-ground topology if the board mixes analog and digital grounds, with the analog return terminating at the same VSS pin that carries the PLL supply.

Route the USB DP/DM pair as a 90-ohm differential with no stubs, keep the pair within 7 mm length matching, and place the common-mode choke near the connector. For the CAN bus use a twisted pair with termination resistors (typically 120 ohm) at each end of the bus. Place the CAN transceiver IC close to the MCF51JE128VLK's CAN_TX/CAN_RX pins to avoid radiating common-mode noise onto adjacent signal traces.

When the MCF51JE128VLK drives long PCB traces or external buses via the EBI/EMI bridge, add 22-33 ohm series-termination resistors near the MCU outputs to damp reflections on the address/data bus. Estimated: at 50 MHz CPU frequency with capacitive loads above 30 pF the unterminated bus can ring for several cycles; series resistors plus a small damping cap stabilise the signal for reliable reads from off-chip memory.

Do not skip configuration of the watchdog timer in production firmware - the WDT peripheral is built in precisely to recover from code runaway, and any customer firmware where WDT is left disabled will be returned for reliability violations. Also ensure the LVD (low-voltage detect) threshold is set conservatively so that brownouts during motor inrush do not corrupt Flash, and keep the RESET pin pulled up with at least 10 kohm plus a 100 nF capacitor for noise filtering.
