MCF51JM64VLH - 32-bit ColdFire V1 MCU 64KB Flash | NXP
MPN: MCF51JM64VLH ⚠ Lần mua cuốiMCF51JM64VLH Tóm tắt
A microcontroller (MCU) is a single-chip computer that integrates a processor core, program memory (Flash), data memory (RAM), and programmable peripherals on one die. The ColdFire V1 core is a 32-bit reduced instruction set computing (RISC) architecture introduced by Freescale (now NXP) as a low-cost derivative of the original ColdFire V2. Compared with 8-bit MCUs, a 32-bit ColdFire V1 device provides higher arithmetic throughput and a wider address space while preserving deterministic interrupt behaviour suited to embedded control.
Key features of the MCF51JM64VLH include 64KB of on-chip Flash program memory, 8KB of SRAM, an integrated USB 2.0 full-speed device controller, a CAN (Controller Area Network) interface, multiple serial communication modules (SCI, SPI, I2C), a 16-channel 12-bit ADC, timers including PWM and input-capture channels, and a real-time counter with a separate backup power domain. The 64-pin LQFP package exposes multiple GPIO lines and provides sufficient I/O for typical industrial and consumer peripherals.
Typical applications for the MCF51JM64VLH include USB-to-UART bridges, low-cost industrial control nodes with CAN connectivity, building automation controllers (thermostats, security panels), human-interface devices (HID) such as custom keyboards and barcode scanners, and consumer appliances requiring a small RTOS-aware 32-bit core. The integrated USB controller makes the device particularly attractive for embedded nodes that must enumerate as a USB device without an external PHY.
When designing with this part, verify the supply voltage range against the specific datasheet revision, since the Flexis family traditionally supports 2.7 V to 5.5 V operation. The 64-pin LQFP uses a 0.5 mm pitch which is hand-solderable but requires a PCB with fine-pitch land pattern. For new designs a similar but more recent Kinetis E or Kinetis KE series device is often preferred; the MCF51JM64VLH is primarily a legacy / last-time-buy option.

Ứng dụng tiêu biểu
MCF51JM64VLH phù hợp cho 6 Áp dụngs: USB-to-UART / USB-CDC Bridge, Industrial CAN Node, Building Automation Controller, USB HID Peripheral (Custom Keyboard / Barcode Scanner), Consumer Appliance Control, USB Diagnostic / Field-Service Tool.
USB-to-UART / USB-CDC Bridge
The MCF51JM64VLH is well suited to USB-to-serial bridge designs thanks to its integrated USB 2.0 Full-Speed device controller with on-chip PHY and 64 KB of Flash for class-driver firmware. Placed as the MCU between an upstream USB host and a downstream UART interface, it enumerates as a CDC device with no external transceiver. Compared with discrete USB bridges, the 32-bit ColdFire V1 core handles baud-rate conversion and buffer management without needing extra glue logic; designers should account for the +5 V-tolerant USB pins and add ESD protection on the USB D+/D- lines.
Được đề xuất
Industrial CAN Node
With its integrated CAN controller and 64 KB Flash capable of holding a CANopen or DeviceNet stack fragment, the MCF51JM64VLH fits low-cost industrial control nodes. The 32-bit ColdFire V1 core handles CAN message filtering in real time with deterministic interrupt latency, and the 64-pin LQFP exposes enough GPIO for digital inputs and MOSFET drivers. Compared with 8-bit S08 devices in the same Flexis family, the JM64 gives more headroom for protocol stacks while keeping peripheral IP shared. A CAN transceiver such as TJA1050 must be added externally for physical-layer signalling.
Được đề xuất
Building Automation Controller
For HVAC, lighting, and security panels the MCF51JM64VLH combines 8 KB SRAM, multi-channel ADC for sensor readout, and SCI/SPI/I2C buses for communication with sensors and actuators. The 50 MHz ColdFire V1 core can run a small RTOS or cooperative scheduler while keeping power consumption low. Designers use the SCI for Modbus RTU towards a central controller and the PWM/timer channels for triac-fired dimmers or motor control loops. Compared with higher-cost Cortex-M4 parts, the JM64 is a cost-optimised choice for fixed-function building-automation products.
Được đề xuất
USB HID Peripheral (Custom Keyboard / Barcode Scanner)
The MCF51JM64VLH's on-chip USB 2.0 Full-Speed device with 64 KB Flash comfortably fits HID-class firmware for custom keyboards, scanners, and POS peripherals. 8 KB of RAM is sufficient for HID report buffers and key-debounce state, while the ADC channels can be repurposed for analogue HID such as joystick axes or battery telemetry. Compared with discrete USB encoder ICs, the JM64 lets engineers implement vendor-specific report formats and field-updatable firmware. Care should be taken to manage USB suspend current per the USB 2.0 specification.
Được đề xuất
Consumer Appliance Control
Consumer appliances such as coffee machines, robotic vacuums, and induction cooktops benefit from the MCF51JM64VLH combination of USB connectivity for in-field firmware updates, CAN for inter-board communication, and PWM channels for power-converter control. The ColdFire V1 core at 50 MHz runs motor-control loops with deterministic timing while leaving headroom for the application layer. Compared with smaller 8-bit parts, the JM64 supports multi-language UI parsing and event logging. Designers should add a brown-out reset and watchdog timer for robust recovery from mains disturbances.
Được đề xuất
USB Diagnostic / Field-Service Tool
Engineers building handheld diagnostic tools over USB use the MCF51JM64VLH as the bridge between USB host software and a target system via UART, SPI, or I2C. The 64 KB Flash holds vendor-class firmware that streams register dumps and accepts command-line updates. The on-chip USB PHY removes the need for external parts, minimising bill-of-material cost for the service tool. Compared with dedicated USB-serial ICs, the JM64 is firmware-definable so the same hardware serves multiple protocols. A robust bootloader is recommended for in-field firmware updates.

Ghi chú thiết kế
The MCF51JM64VLH requires a clean 2.7-5.5 V digital supply and a separate filtered USB supply for the on-chip USB PHY. Bulk-decouple the digital VDD with at least 1 µF ceramic plus a 10 µF bulk capacitor per supply pin pair, and place a ferrite bead between the digital and USB regulators if the USB bus is expected to see hot-plug events. Estimated: at 50 MHz CPU clock with all peripherals active, core draw is in the tens of mA - consult the MCF51JM datasheet power-management chapter for exact figures.
Use a 4-layer PCB with a continuous ground plane under the 64-pin LQFP to minimise EMI from the 50 MHz system clock and USB switching. Route USB D+ and D- as a 90-ohm differential pair with no stubs, and keep the pair length-matched within 150 mil. Place the 27 pF USB D+/D- series resistors as close to the IC pins as possible. Estimated via-stub length should be kept under 100 mil to maintain signal integrity.
Because the part is flagged for End-of-Life on the NXP product page, do not start a new production design with the MCF51JM64VLH without securing a last-time-buy allocation. If you must use it, plan a Kinetis KE migration path from the start so firmware can be ported incrementally. Also be aware that the ColdFire V1 ISA is not source-compatible with Kinetis KE ARM Cortex-M0+, so toolchain migration is required for direct performance upgrades.
Thông tin tuân thủ
NXP product page does not publish a fully machine-readable compliance list for the MCF51JM64VLH. The part is supplied lead-free per NXP standard ordering part number convention; RoHS, REACH, and conflict-mineral statements should be requested directly from NXP. AEC-Q100 qualification is not applicable to the Flexis JM family as it is not marketed as an automotive-grade part.
