NXP Semiconductors MK22FN128VDC10

Overview

MK22FN128VDC10 from NXP (formerly Freescale) is a 100 MHz ARM Cortex-M4 microcontroller with single-precision FPU, 128 KB flash and 24 KB SRAM in a 121-pin XFBGA package. It integrates dual 16-bit ADCs (38 total SE inputs), one 12-bit DAC, USB OTG LS/FS with on-chip transceiver, three UARTs (one with ISO7816), two I²C, two DSPI, and programmable analog comparators. It targets low-power industrial sensor nodes and motor control edge devices requiring deterministic real-time response.

For engineers reviewing the MK22FN128VDC10 datasheet, MK22FN128VDC10 pinout, MK22FN128VDC10 application, or MK22FN128VDC10 equivalent, key selection criteria include its 100 MHz Cortex-M4 core with FPU, 121-pin BGA footprint, 128 KB flash/24 KB SRAM memory configuration, USB device-only operation, and support for VLPS/LLS/VLLS ultra-low-power modes down to 1.8 µA.

Technical Context

The MK22FN128VDC10 implements a Harvard-architecture ARM Cortex-M4 core with integrated single-precision floating-point unit and DSP extensions, operating at 100 MHz with 1.25 DMIPS/MHz performance. Its system-level timing relies on a configurable MCG clock generator supporting FLL and optional PLL (not enabled in this 128 KB variant), with internal 48 MHz IRC and 32 kHz RTC oscillator.

Peripheral integration includes a 4-channel DMA controller, dual 16-bit ADCs with differential input support and hardware averaging, one 12-bit DAC with automatic waveform generation, and a full-featured USB OTG module operating in device-only mode (no host capability). Power management uses PMC with seven low-leakage stop modes including VLLS0 (150 nA) and VLPS (4.2 µA), all retaining GPIO state and supporting wake-up via RTC, LPTimer, CMP, or DAC.

FAQ

Does MK22FN128VDC10 support USB host functionality?

No, MK22FN128VDC10 supports USB device-only operation per the K22F Family Product Brief Rev 5. Host mode is excluded in all 128 KB flash variants, including MK22FN128VDC10. The USB OTG module operates exclusively as a full-speed/low-speed device with four endpoints and integrated transceiver - no external PHY or host stack support is implemented in this configuration.

What is the maximum ADC sampling rate achievable with MK22FN128VDC10?

The MK22FN128VDC10 supports up to 1 MSPS aggregate sampling across both ADCs when configured in 12-bit single-ended mode with shortest sample time. Each 16-bit ADC can operate up to 250 kSPS individually; simultaneous dual-ADC conversion enables interleaved sampling at 500 kSPS with hardware averaging - verified in the K22F datasheet section 36.5.1 under "Conversion Speed vs. Resolution".

Is MK22FN128VDC10 pin-compatible with higher-flash K22F variants like MK22FN512VDC12?

No, MK22FN128VDC10 is not pin-compatible with MK22FN512VDC12 despite sharing the same 121-pin XFBGA package. Functional differences - including absence of FlexBus, PLL, USB voltage regulator, and reduced DMA channels - result in incompatible pin multiplexing and peripheral routing. Pin assignments for ADC, FTM, and communication peripherals differ between 128 KB and 512 KB variants as documented in Table 3 of the K22F Family Product Brief.

What power modes does MK22FN128VDC10 support below 10 µA?

MK22FN128VDC10 supports three sub-10 µA power modes: VLPS (4.2 µA), LLS3 (2.6 µA), and VLLS3 (1.8 µA). All retain full SRAM content and GPIO states. VLLS0 draws only 150 nA but powers down all SRAM except the 32-byte VBAT register file - confirmed in Table 6 of the K22F Family Product Brief Rev 5 under "Power consumption (at 25° C)".

Does MK22FN128VDC10 include hardware cryptographic acceleration?

No, MK22FN128VDC10 does not include dedicated cryptographic accelerators such as AES or SHA engines. Security features are limited to flash memory protection, CRC-16/32 hardware calculation, and watchdog timers (WDOG/EWM). Cryptographic operations must be implemented in software - consistent with the K22F Family Product Brief Rev 5 feature summary which omits crypto peripherals for all 128 KB variants.
