Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MK22FN512VLH12 | Higher flash (512 KB), higher max frequency (120 MHz), no FlexMemory - uses standard flash/RAM partitioning | Better suited for complex protocol stacks (e.g., BLE + USB + TCP/IP) where code size exceeds 128 KB | Select when application requires >128 KB flash and does not rely on FlexNVM EEPROM emulation |
| K22F512VLH12 | Same 512 KB flash and 120 MHz speed as MK22FN512VLH12 but adds FPU; also lacks FlexMemory | Required for floating-point intensive tasks (e.g., FFT-based spectral analysis) where FPU acceleration is mandatory | Choose only if floating-point computation dominates workload and FlexMemory is unnecessary |
Compared with MK22DX128VLH5, MK22FN512VLH12 offers greater code capacity and speed but sacrifices FlexMemory's EEPROM-like write flexibility, while K22F512VLH12 adds FPU capability at the cost of both FlexMemory and compatibility with legacy MK22DX-based firmware.

FAQ
What is the maximum operating frequency of the MK22DX128VLH5?
The MK22DX128VLH5 operates at a maximum core/system clock frequency of 50 MHz. This is specified under normal run mode conditions with VDD = 1.71–3.6 V and ambient temperature from –40°C to +105°C. The device maintains full functionality-including USB OTG, ADC, and DMA-at this speed, and its performance is validated at 1.25 Dhrystone MIPS per MHz.
Does the MK22DX128VLH5 include FlexMemory, and how is it configured?
Yes, the MK22DX128VLH5 includes FlexMemory: 64 KB FlexNVM and 4 KB FlexRAM. Unlike standard flash, FlexNVM supports EEPROM-like byte/word programming and erase operations with >1 million endurance cycles, while FlexRAM provides fast, nonvolatile data storage that retains content during power loss without external backup capacitors.
What USB capabilities does the MK22DX128VLH5 support?
The MK22DX128VLH5 integrates a full-/low-speed USB On-The-Go controller with an on-chip transceiver, supporting device, host, and OTG roles. It includes USB Device Charger Detect (DCD) logic to identify USB power sources and complies with USB 2.0 specifications - eliminating the need for external PHY components or discrete charger detection circuitry.
What are the lowest-power operating modes supported by the MK22DX128VLH5?
The MK22DX128VLH5 supports Very-Low-Leakage Stop (VLLS) modes, with VLLS0 drawing as low as 0.54 μA (typ.) at 3.0 V and –40°C to +25°C when POR detect is enabled. This mode retains RAM and selected registers while allowing wake-up via GPIO, RTC alarm, or low-power timer - ideal for battery-powered wake-on-event applications.
Is the MK22DX128VLH5 pin-compatible with other K22 family members?
No, the MK22DX128VLH5 is not universally pin-compatible across the K22 family. While it shares the 64-pin LQFP (LH) package with variants like MK22DN512VLH5, pin functions differ due to varying peripheral sets and memory configurations. Engineers must verify signal mapping using the K22 Pin Assignments table in the K22P64M50SF4 datasheet before substituting.
