Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MK22FX512VLQ12 | 512 KB flash, same 128 KB SRAM, identical pinout and peripheral set | Lower firmware footprint requirement; no FlexNVM support | Select when application firmware fits in 512 KB and EEPROM-like FlexNVM is unnecessary |

FAQ
What is the maximum operating frequency of the MK22FN1M0VLQ12 core?
The MK22FN1M0VLQ12 features an ARM Cortex-M4 core with FPU rated for up to 120 MHz operation. This frequency is achievable with the Phase-Locked Loop (PLL) enabled and proper voltage supply (≥2.7 V); at lower voltages (1.71–2.7 V), maximum frequency is reduced per datasheet electrical specifications. The MK22FN1M0VLQ12 maintains full peripheral functionality-including USB OTG and CAN-at 120 MHz.
Does the MK22FN1M0VLQ12 include an integrated USB voltage regulator?
Yes, the MK22FN1M0VLQ12 integrates a 3.3 V, 120 mA LDO specifically for USB operation. This regulator powers the internal USB transceiver and can supply external circuitry, eliminating the need for an external USB LDO in most designs. The MK22FN1M0VLQ12 datasheet specifies USB regulator output tolerance and load regulation performance across temperature and input voltage ranges.
What low-power modes does the MK22FN1M0VLQ12 support, and what is the lowest current draw?
The MK22FN1M0VLQ12 supports multiple low-power modes including VLPR, VLPS, LLS, and VLLS0–VLLS3. In VLLS0 mode with POR detect disabled, it achieves 268 nA typical current draw at 3.0 V and 25°C while retaining full register and RAM state. Wakeup time from VLLS0 is 5.0 μs, enabling rapid response to external interrupts. The MK22FN1M0VLQ12's low-leakage wakeup unit allows selective pin-triggered wake from all VLLS modes.
Can the MK22FN1M0VLQ12 execute code directly from RAM?
Yes, the MK22FN1M0VLQ12 supports executing code from SRAM, which is useful for time-critical routines or firmware updates. Its memory map allocates 128 KB of tightly coupled SRAM accessible at full core speed. While flash remains the primary non-volatile execution medium, the MK22FN1M0VLQ12's flexible memory controller allows remapping and cache configuration to optimize SRAM execution performance without violating memory protection boundaries.
Is the MK22FN1M0VLQ12 pin-compatible with other K22F family members?
Yes, the MK22FN1M0VLQ12 in 144-pin LQFP is pin-compatible with MK22FX512VLQ12, MK22FN1M0VMD12, and MK22FX512VMD12 within the same package variant (LQFP vs. BGA). Signal multiplexing and pin assignments follow the K22P144M120SF5 reference, ensuring PCB reuse across flash-size variants. However, FlexNVM/FlexRAM configuration differs between FN (FlexMemory enabled) and FX (FlexMemory disabled) suffixes, requiring firmware adaptation even with identical pinouts.
