FAQ
What is the maximum operating frequency and core type of the MK22DX128VMC5?
The MK22DX128VMC5 features an ARM Cortex-M4 core with DSP extension, rated for up to 50 MHz operation. This delivers 1.25 Dhrystone MIPS per MHz (62.5 DMIPS total), enabling real-time signal processing, motor control algorithms, and USB protocol stack execution without external acceleration. The MK22DX128VMC5 achieves this performance within its 1.71–3.6 V supply range and –40 to 105°C temperature specification.
Does the MK22DX128VMC5 include on-chip USB physical layer support?
Yes, the MK22DX128VMC5 integrates a full-speed/low-speed USB 2.0 On-The-Go controller with an on-chip transceiver. This eliminates the need for an external USB PHY, reducing bill-of-materials cost and PCB area. The MK22DX128VMC5 supports USB device, host, and OTG roles, including USB Device Charger Detect (DCD) per USB Battery Charging v1.2, all implemented in silicon without external components.
What memory resources are available on the MK22DX128VMC5 beyond main flash and RAM?
In addition to 128 KB program flash and 64 KB SRAM, the MK22DX128VMC5 includes FlexMemory: 64 KB FlexNVM (emulating EEPROM with byte-write and 100k-cycle endurance) and 4 KB FlexRAM (retained in low-power modes). This architecture allows persistent data storage, firmware parameter tables, and wear-leveling without external serial EEPROM - a key differentiator of the MK22DX128VMC5 within the K22 family.
How does the MK22DX128VMC5 support ultra-low-power operation in battery-powered applications?
The MK22DX128VMC5 offers seven low-power modes, including VLLS0 (Very Low-Leakage Stop Mode 0) drawing just 0.54 µA (typ) with POR circuit enabled. In this mode, the RTC, low-leakage wakeup unit, and FlexRAM retain state while the core and most peripherals are powered down. This capability makes the MK22DX128VMC5 ideal for energy-harvesting or coin-cell-powered nodes requiring years of operation between replacements.
What analog peripherals are integrated into the MK22DX128VMC5?
The MK22DX128VMC5 integrates a 16-bit SAR ADC with hardware averaging and programmable gain amplifier, two independent 12-bit DACs, two analog comparators each with a 6-bit DAC and programmable reference, and a precision voltage reference module. These resources enable high-fidelity sensor signal conditioning, closed-loop analog control, and accurate voltage monitoring - all without external op-amps or DACs - confirming the MK22DX128VMC5's suitability for precision industrial and medical applications.
