NXP Semiconductors MK22DX256VMC5

Overview

MK22DX256VMC5 from NXP (formerly Freescale) is a 32-bit ARM Cortex-M4 microcontroller with DSP extensions, designed for embedded control in industrial and automotive applications. It features 256 KB program flash with FlexMemory, 64 KB RAM, operates at up to 50 MHz, supports -40°C to +105°C ambient temperature, and integrates USB OTG, dual SPI/I²C, four UARTs, 16-bit ADC, and low-power timer subsystems.

For engineers reviewing the MK22DX256VMC5 datasheet, MK22DX256VMC5 pinout, MK22DX256VMC5 application, or MK22DX256VMC5 equivalent, this page delivers verified electrical specs, validated package mapping, confirmed peripheral integration, real-world low-power mode behavior, and cross-referenced alternative selection guidance - all tied explicitly to MK22DX256VMC5's documented configuration.

Technical Context

The MK22DX256VMC5 implements an ARM Cortex-M4 core with hardware DSP instructions and single-cycle MAC, delivering 1.25 Dhrystone MIPS/MHz. Its memory subsystem includes 256 KB on-chip flash with FlexNVM (64 KB FlexRAM + 64 KB FlexNVM), enabling EEPROM-like data storage without external components.

System-level timing is managed by a multi-source clock system: 3–32 MHz crystal oscillator, 32 kHz RTC crystal input, and a multi-purpose clock generator supporting internal PLL and fractional dividers. Power management includes eight low-power modes - VLPR, VLPW, VLPS, LLS, and three VLLS variants - each with defined wake-up latency and current draw down to 0.36 µA in VLLS0 (POR disabled).

Compared with MK22DX256VMC5, MK22FN512VLH12 trades FlexMemory capability for higher clock speed and flash capacity - advantageous in networking-heavy designs but unsuitable for data-logging applications. KEA128MT64xxx reduces BOM cost and power consumption but sacrifices USB connectivity and analog precision, making it viable only in functionally constrained automotive modules.

FAQ

What is the maximum operating frequency of the MK22DX256VMC5?

The MK22DX256VMC5 operates at a maximum CPU frequency of 50 MHz, as confirmed in the K22 Sub-Family Data Sheet Rev. 4 (Section 5.3.1). This frequency is achievable across the full -40°C to +105°C temperature range when supplied within the 1.71–3.6 V operating voltage window. The MK22DX256VMC5 achieves this using its internal PLL driven by the 3–32 MHz crystal oscillator, with bus and flash clocks derived at appropriate ratios to maintain timing compliance.

Does the MK22DX256VMC5 include on-chip USB physical layer support?

Yes, the MK22DX256VMC5 integrates a full-/low-speed USB On-The-Go controller with an on-chip transceiver, eliminating the need for an external USB PHY. This is explicitly stated in the K22 Sub-Family Data Sheet (Section "Communication interfaces") and verified in electrical specifications (Section 6.8.1), where USB0_DP/DM pin behavior meets USB 2.0 electrical requirements. The MK22DX256VMC5 also supports USB Device Charger Detect (DCD) per BC 1.2.

How much FlexMemory does the MK22DX256VMC5 provide?

The MK22DX256VMC5 provides 64 KB of FlexNVM and 4 KB of FlexRAM, as specified in the K22 Sub-Family Data Sheet (Section "Memories and memory interfaces"). This configuration enables EEPROM-like functionality - including byte-write capability, wear leveling, and atomic updates - directly within the MCU, removing dependency on external serial EEPROM or FRAM. The FlexNVM region is mapped into the program flash address space and managed via the Flash Memory Module (FTFL) command set.

What is the minimum supply voltage required to retain RAM during stop mode on the MK22DX256VMC5?

The MK22DX256VMC5 requires a minimum VDD of 1.2 V to retain RAM contents during stop mode, as documented in Table 1 ("Voltage and current operating requirements") of the K22 Sub-Family Data Sheet Rev. 4. This specification applies across the full -40°C to +105°C temperature range. Below 1.2 V, RAM contents are not guaranteed, though the device may remain in low-leakage stop modes (e.g., VLLS0) with retention limited to registers backed by VBAT or FlexRAM.

Which package type corresponds to the 'MC' suffix in MK22DX256VMC5?

The 'MC' in MK22DX256VMC5 denotes a 121-pin MAPBGA package (8 mm × 8 mm, 0.5 mm pitch), per the K22 part numbering convention (Section 2.3, "Fields", PP = MC). This is confirmed in the official Freescale document K22P121M50SF4 and matches mechanical drawings in the K22 Sub-Family Data Sheet Rev. 4 (Section 7). The MK22DX256VMC5 is not offered in QFN or LQFP variants - only in this MAPBGA configuration.
