Product details
Overview
MK70FN1M0VMJ12 from NXP (formerly Freescale) is a high-performance, industrial-grade ARM Cortex-M4 microcontroller with single-precision FPU, 1 MB on-chip flash, 128 KB SRAM, and integrated IEEE 1588 Ethernet MAC - designed for real-time industrial control, networked HMI, and secure edge-node applications requiring deterministic timing, cryptographic acceleration, and graphics-capable display interfaces.
For engineers reviewing the MK70FN1M0VMJ12 datasheet, MK70FN1M0VMJ12 pinout, MK70FN1M0VMJ12 application, or MK70FN1M0VMJ12 equivalent, this page delivers verified technical context, package-specific pin mapping, functional alternatives, and supply-chain-ready availability details - all grounded in the official K70 Family Product Brief Rev. 8 (2011) and part-number decoding rules.
Technical Context
The MK70FN1M0VMJ12 implements an ARM Cortex-M4 core with DSP extensions and hardware single-precision floating-point unit (SPFPU), operating at up to 120 MHz with 1.25 DMIPS/MHz performance. It integrates a full IEEE 1588-compliant Ethernet MAC with MII/RMII support, dual CAN 2.0B controllers, and USB OTG HS/FS/LS with device charger detect (DCD) and 120 mA regulator.
This device belongs to the K70N sub-family and uses a 256-pin MAPBGA (17 mm × 17 mm) package with DDR controller, NAND flash controller, 16 KB instruction/data cache, and FlexMemory architecture - though it omits FlexNVM/FlexRAM (denoted by "N" in part number), relying solely on 1 MB program flash and 128 KB SRAM.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-performance industrial MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MK70FX512VMJ12 | 512 KB flash + 512 KB FlexNVM + 16 KB FlexRAM - lacks 1 MB monolithic flash but adds EEPROM-like byte-write capability. | Better suited for applications requiring frequent non-volatile parameter storage (e.g., calibration tables) without wear-leveling software. | Select MK70FX512VMJ12 if EEPROM emulation or bootloader/data partitioning flexibility outweighs raw flash capacity. |
| RT1052CVL5B | NXP i.MX RT1050 series: Cortex-M7 @ 600 MHz, 512 KB SRAM, no on-chip flash - requires external QSPI flash and lacks integrated Ethernet MAC. | Targeted at higher-throughput applications (e.g., AI inference at edge) where raw CPU speed and external memory bandwidth dominate over integrated peripherals. | Choose RT1052CVL5B only when migrating to higher clock rates and external memory architecture is acceptable - not a drop-in replacement. |
Compared with MK70FN1M0VMJ12, MK70FX512VMJ12 trades flash density for FlexMemory configurability, while RT1052CVL5B abandons integrated flash and Ethernet for raw Cortex-M7 performance - making MK70FN1M0VMJ12 optimal for self-contained, Ethernet-connected industrial controllers needing maximum on-chip code storage and deterministic timing.

FAQ
What is the maximum operating frequency of the MK70FN1M0VMJ12?
The MK70FN1M0VMJ12 operates at a maximum CPU frequency of 120 MHz, as confirmed by its part-number suffix "12" and the K70 120 MHz Performance Table. This frequency is sustained across the full −40 °C to +105 °C temperature range and 1.71–3.6 V supply voltage, enabling deterministic real-time execution for industrial control loops and protocol stacks without thermal throttling.
Does the MK70FN1M0VMJ12 include FlexMemory (FlexNVM/FlexRAM)?
No, the MK70FN1M0VMJ12 does not include FlexMemory. Its part number contains "N" (not "X") in the key attribute field, indicating program flash only - confirmed in Table 3 of the K70 Family Product Brief, which lists FlexNVM and EEPROM/FlexRAM as "–" for this variant. It relies solely on 1 MB of main program flash and 128 KB of SRAM.
Which Ethernet standards does the MK70FN1M0VMJ12 support?
The MK70FN1M0VMJ12 integrates a full IEEE 802.3-compliant Ethernet MAC with IEEE 1588-2008 Precision Time Protocol (PTP) hardware timestamping support. It supports both MII and RMII physical layer interfaces - enabling connection to standard Ethernet PHYs - and delivers sub-100 ns timestamp resolution for time-sensitive networking in industrial automation and power grid applications.
What debug interfaces are available on the MK70FN1M0VMJ12?
The MK70FN1M0VMJ12 supports JTAG, cJTAG, and 2-pin Serial Wire Debug (SWD) interfaces, along with full CoreSight trace capability including TPIU, FPB, DWT, ITM, ETM, and ETB modules. These enable non-intrusive real-time debugging, instruction tracing, and performance profiling - essential for validating deterministic behavior in safety-critical industrial firmware.
Is the MK70FN1M0VMJ12 pin-compatible with other K70 family members?
Yes, the MK70FN1M0VMJ12 is pin-compatible with all other K70 devices in the 256-pin MAPBGA (MJ) package, including MK70FX512VMJ12, MK70FN1M0VMJ15, and MK70FX512VMJ15 - as explicitly stated in Table 2 ("All devices which share a common package are pin-for-pin compatible"). This enables hardware reuse across performance and memory variants without PCB redesign.
