NXP Semiconductors MK12DX128VMC5

Overview

MK12DX128VMC5 from NXP Semiconductors (formerly Freescale) is a 50 MHz ARM Cortex-M4 microcontroller with DSP extension, 128 KB program flash, 64 KB RAM, and FlexMemory (4 KB FlexRAM + 64 KB FlexNVM), designed for industrial control and sensor fusion applications requiring deterministic real-time response and low-power operation across –40 to 105°C ambient.

For engineers reviewing the MK12DX128VMC5 datasheet, MK12DX128VMC5 pinout, MK12DX128VMC5 application, or MK12DX128VMC5 equivalent, key selection criteria include its 50 MHz core frequency, dual 32 kHz/3–32 MHz crystal support, 16-bit SAR ADC with 12-bit DAC, four UARTs, USB Device Charger Detect, and VLLS0 stop mode current as low as 0.359 µA at 3.0 V.

Technical Context

The MK12DX128VMC5 implements an ARM Cortex-M4 core with hardware DSP instructions and single-cycle MAC, paired with a multi-purpose clock generator supporting internal and external oscillators (3–32 MHz main, 32 kHz RTC). Its memory subsystem integrates 128 KB flash, 64 KB SRAM, and FlexMemory architecture enabling EEPROM-like wear leveling via 4 KB FlexRAM and 64 KB FlexNVM.

Peripherals include eight-channel PWM timer with motor control capability, two 2-channel general-purpose timers (one with quadrature decoder), real-time clock, carrier modulator transmitter, and communication interfaces: two SPI, two I²C, four UART, I²S, and USB Device Charger Detect - all operating within 1.71–3.6 V supply range and qualified for extended temperature.

FAQ

What is the maximum operating frequency of the MK12DX128VMC5?

The MK12DX128VMC5 operates at a maximum core/system clock frequency of 50 MHz, as confirmed by its part number suffix 'C5' and verified in the K12P121M50SF4 datasheet Section 5.3.1. This frequency is achievable across the full –40 to 105°C temperature range when supplied with 1.71–3.6 V and using the MCG in FEI or PEE mode with appropriate clock dividers. The MK12DX128VMC5 does not support frequencies above 50 MHz.

Does the MK12DX128VMC5 include FlexMemory, and how is it configured?

Yes, the MK12DX128VMC5 includes FlexMemory: 64 KB FlexNVM and 4 KB FlexRAM, as indicated by the 'X' in its part number (MK12DX128VMC5) and explicitly stated in the K12 Sub-Family Data Sheet Section 2.3. This configuration enables EEPROM-like functionality - allowing byte-level writes, wear leveling, and data retention without block erases - and is factory-configured; no runtime reconfiguration of FlexMemory size is supported on the MK12DX128VMC5.

What package type does the MK12DX128VMC5 use, and what are its key mechanical attributes?

The MK12DX128VMC5 uses a 121-pin MAPBGA package (MC suffix), measuring 8 mm × 8 mm with 0.5 mm ball pitch, per the K12 Sub-Family Data Sheet Section 2.3 and Table 7. It has moisture sensitivity level 3 (MSL3), requires lead-free reflow per J-STD-020, and features 121 I/O balls including dedicated VDD/VSS pairs and separate analog power/ground balls - critical for maintaining signal integrity in mixed-signal designs using the MK12DX128VMC5.

Can the MK12DX128VMC5 operate from a single 3.3 V supply, and what are the voltage limits?

Yes, the MK12DX128VMC5 operates from a single 3.3 V supply within its specified 1.71–3.6 V range, as defined in Section 5.2.1 of the K12P121M50SF4 datasheet. Both digital (VDD) and analog (VDDA) supplies must be within this range, with differential limits of ±0.1 V between them. Operation below 1.71 V risks brown-out reset or undefined behavior; exceeding 3.6 V violates absolute maximum ratings and may cause permanent damage to the MK12DX128VMC5.

What low-power modes are supported by the MK12DX128VMC5, and what is the lowest achievable current?

The MK12DX128VMC5 supports multiple low-power modes including VLPR, VLPS, LLS, and VLLS0–VLLS3. The lowest current is achieved in VLLS0 mode with POR detect circuit disabled: 0.359 µA at 3.0 V and –40 to 25°C, per Table 6 in the K12P121M50SF4 datasheet. This mode retains RAM and selected registers while disabling all clocks - making it ideal for battery-backed applications where the MK12DX128VMC5 must wake periodically via RTC or GPIO.
