Product details
Overview
MKS22FN128VLH12 from NXP Semiconductors is a 120 MHz ARM® Cortex®-M4 microcontroller with FPU, 128 KB flash, 64 KB SRAM, and dual FlexCAN interfaces-designed for real-time automotive body control, industrial sensor fusion, and CAN-based gateway applications requiring deterministic timing and low-power operation.
For engineers reviewing the MKS22FN128VLH12 datasheet, MKS22FN128VLH12 pinout, MKS22FN128VLH12 application, or MKS22FN128VLH12 equivalent, key selection criteria include its 64-pin LQFP package, –40 to 105 °C operating range, USB FS OTG with crystal-less operation, and dual CAN 2.0B compliance per ISO 11898-1.
Technical Context
The MKS22FN128VLH12 implements a dual-FlexCAN architecture supporting concurrent CAN FD-ready message handling and hardware-based wakeup on CAN_RX edges in VLPS/Stop modes. Its MCG clock system integrates PLL, FLL, and three internal oscillators (32 kHz, 4 MHz, 48 MHz) to enable dynamic frequency scaling across HSRUN/RUN/VLPR modes.
It features a 16-bit ADC with up to 14 single-ended channels and 2 differential channels in 64-LQFP, plus a 12-bit DAC and programmable delay block (PDB), all accessible while retaining SRAM in low-leakage stop modes-enabling precise analog-triggered wake-up and time-critical waveform generation without full core restart.
Key Specifications
