For engineers reviewing the MK65FX1M0VMI18 datasheet, MK65FX1M0VMI18 pinout, MK65FX1M0VMI18 application, or MK65FX1M0VMI18 equivalent, this page delivers verified technical context, validated package mapping (169-pin MAPBGA, 9 mm × 9 mm, 0.65 mm pitch), confirmed peripheral integration (dual CAN, 3 SPI, 4 I²C, 6 UART including LPUART0), and precise power mode behavior (VLLS0 current down to 0.254 µA at 3.0 V).

Technical Context

The MK65FX1M0VMI18 implements an ARM Cortex-M4F core with tightly coupled memory subsystem, hardware FPU, and DSP extensions enabling deterministic signal processing. Its clock system integrates multiple oscillators (3–32 MHz crystal, 32 kHz low-power crystal, 48 MHz IRC) and configurable PLLs supporting high-speed run (180 MHz), HSRun (168 MHz), and VLPR (4 MHz) modes with dynamic voltage/frequency scaling.

Peripheral architecture includes dual USB controllers-one with integrated high-speed PHY and another with full-speed transceiver-plus Ethernet MAC with MII/RMII interfaces and hardware IEEE 1588 timestamping. Security is enforced via CAU accelerator (AES/DES/SHA), hardware RNG, and multi-level flash protection, while analog subsystem comprises two 16-bit SAR ADCs, two 12-bit DACs, four analog comparators with 6-bit DACs, and TSI touch interface.

FAQ

What is the maximum operating frequency of the MK65FX1M0VMI18 core?

The MK65FX1M0VMI18 features an ARM Cortex-M4F core rated for up to 180 MHz operation in High-Speed Run mode. This frequency is achievable with proper power supply decoupling, thermal management, and clock configuration using the internal PLL driven by the main 3–32 MHz crystal oscillator. The MK65FX1M0VMI18 maintains full peripheral functionality-including Ethernet MAC and dual USB-at this speed.

Does the MK65FX1M0VMI18 include hardware support for IEEE 1588 Precision Time Protocol?

Yes, the MK65FX1M0VMI18 integrates dedicated IEEE 1588 timestamping logic within its Ethernet MAC. It captures precise transmit and receive timestamps at the PHY interface boundary with sub-microsecond resolution, enabling compliant PTP slave operation without software overhead. This hardware feature is confirmed in the K65 Reference Manual (K65P169M180SF5RMV21) Section 38.3.3.

What is the lowest power consumption mode supported by the MK65FX1M0VMI18, and what is its typical current draw?

The MK65FX1M0VMI18 supports Very Low-Leakage Stop Mode 0 (VLLS0) with POR detect circuit disabled, achieving a typical current draw of 0.254 µA at 3.0 V and -40°C to 25°C ambient. This mode retains RAM content, RTC operation, and wake-up capability via selected GPIOs or low-power timers-ideal for battery-backed applications requiring multi-year operation.

How much flash memory does the MK65FX1M0VMI18 have, and is it partitionable for data storage?

The MK65FX1M0VMI18 contains 1.25 MB of on-chip program flash memory. Unlike FlexMemory variants (e.g., MK65FN2M0VMI18), this part is a non-FlexMemory device and does not support runtime reconfiguration of flash into EEPROM-like data storage. Its flash is optimized for code execution only, with standard erase/program granularity per the FTFE module specification.

Which USB configurations are supported by the MK65FX1M0VMI18, and does it require external PHY components?

The MK65FX1M0VMI18 integrates two independent USB controllers: USB0 supports high-speed (480 Mbps), full-speed (12 Mbps), and low-speed (1.5 Mbps) On-The-Go operation with an on-chip high-speed PHY; USB1 supports full-speed and low-speed OTG with an on-chip transceiver. Neither interface requires external PHY components-only standard USB termination resistors and ESD protection diodes are needed for compliance.
