Overview
MCF51JF64VLF from NXP Semiconductors (formerly Freescale) is a 32-bit ColdFire V1 microcontroller with 64 KB flash, 128 KB FlexNVM, and 8 KB RAM, operating at up to 50 MHz. It integrates USB OTG, 12-bit ADC/DAC, hardware cryptographic acceleration (CAU), and 10 low-power modes. Used in industrial control panels requiring secure, low-power edge processing with analog sensing and USB connectivity.
For engineers reviewing the MCF51JF64VLF datasheet, MCF51JF64VLF pinout, MCF51JF64VLF application, or MCF51JF64VLF equivalent, key selection criteria include its -40°C to 105°C temperature range, 1.71–3.6 V supply, integrated LLWU wakeup unit, and LQFP-48 package compatibility with space-constrained industrial HMI designs.
Technical Context
The MCF51JF64VLF implements a ColdFire V1 core with Dhrystone 2.1 performance of 0.99 DMIPS/MHz from flash and 1.10 DMIPS/MHz from RAM. Its multipurpose clock generator (MCG) supports three crystal oscillator ranges (1 kHz–32 MHz) and enables dynamic clock scaling across 10 power modes including VLLS1–VLLS3 stop states.
Peripherals include a 12-bit SAR ADC with programmable reference, dual 12-bit DACs (one embedded in comparator), FTM/PDB/LPTMR timers, UARTs with Smart Card support, I²C, SPI with FIFO, I²S/SAI audio interface, and Mini-FlexBus for external memory expansion - all accessible via 48 EGPIO pins with configurable slew rate and digital/analog filtering.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Kinetis K22FN512VLH12 | ARM Cortex-M4F core, 120 MHz, 512 KB flash, no integrated USB transceiver - requires external PHY | Higher compute throughput but larger footprint (64-LQFP); lacks CAU - uses software crypto libraries | Select when floating-point DSP capability and larger memory are prioritized over USB integration and ultra-low-power stop modes |
| MCF51JM128VLF | Same ColdFire V1 architecture, 128 KB flash, identical 48-LQFP package and pinout - superset memory variant | Direct drop-in replacement with increased flash for larger firmware images; same peripheral set and power profile | Select when firmware growth exceeds 64 KB but board layout and qualification must remain unchanged |
Compared with K22FN512VLH12, MCF51JF64VLF offers lower active power and integrated USB PHY at the cost of ARM ecosystem tooling; versus MCF51JM128VLF, it trades flash capacity for cost-sensitive deployments where 64 KB suffices.

FAQ
What is the maximum operating frequency of the MCF51JF64VLF core?
The MCF51JF64VLF features a ColdFire V1 core rated for up to 50 MHz system and core clock frequency in normal run mode. In very low-power run (VLPR) mode, the maximum core clock is 2 MHz. These frequencies are validated across the full -40°C to 105°C ambient temperature range and 1.71–3.6 V supply voltage, as specified in the MCF51JF128 datasheet Rev. 7.
Does the MCF51JF64VLF include an integrated USB transceiver?
Yes, the MCF51JF64VLF includes a full/low-speed USB On-The-Go controller with an integrated on-chip transceiver. This eliminates the need for external PHY components and supports both host and device roles. The USB_DP and USB_DM pins are routed directly to the transceiver, requiring only standard 90 Ω differential impedance PCB routing for compliance.
What low-power modes does the MCF51JF64VLF support, and what is the lowest current draw?
The MCF51JF64VLF supports 10 low-power modes, including VLLS1–VLLS3 stop states. In VLLS3 mode at 3.0 V, typical current draw is 1.8 µA at -40°C to 25°C and 3.3 µA at 105°C. Wakeup latency from VLLS3 to RUN mode is ≤92 µs, enabled by the low-leakage wakeup unit (LLWU) for fast response to external events.
Is the MCF51JF64VLF pin-compatible with other members of the MCF51JF family?
The MCF51JF64VLF uses a 48-pin LQFP package (LF suffix). It shares identical pinout with MCF51JF32VFM (32-QFN) and MCF51JF64VHS (44-Laminate QFN) only in signal function mapping - not physical compatibility. Within the same package type, MCF51JM128VLF (same 48-LQFP) is pin-compatible and functionally identical except for doubled flash capacity.
What security features are implemented in hardware on the MCF51JF64VLF?
The MCF51JF64VLF includes hardware-based security features: a cryptographic acceleration unit (CAU) supporting AES-128/256 and SHA-1/256, a hardware random number generator (RNGB), a CRC computation module, and a factory-programmed 128-bit unique identification number. These enable secure boot, firmware signing, and TLS offload without software-only crypto libraries.
