Product details
Overview
MKS22FN128VLL12 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 industrial control, automotive body electronics, and CAN-based gateway applications requiring deterministic timing and low-power operation.
For engineers reviewing the MKS22FN128VLL12 datasheet, MKS22FN128VLL12 pinout, MKS22FN128VLL12 application, or MKS22FN128VLL12 equivalent, key selection criteria include its 100-pin LQFP package, –40 to 105 °C operating range, USB FS OTG with crystal-less mode, FlexIO programmable interface, and dual CAN 2.0B compliance per ISO 11898-1.
Technical Context
The MKS22FN128VLL12 implements a dual-FlexCAN architecture with independent message buffers and FIFOs, supporting concurrent CAN FD-ready messaging on two buses. Its MCG clock system integrates FLL and PLL with multiple internal/external sources-including 32 kHz RTC oscillator and 48 MHz IRC-to sustain real-time peripheral operation across Run, VLPR, Stop, and VLPS modes.
FlexIO provides hardware-configurable serial protocols (UART, SPI, I²S, PWM) without CPU intervention, while the 16-bit ADC delivers up to 1.2 Msps at ≤13-bit resolution with 17 single-ended/4 differential channels-enabling simultaneous sensor acquisition and motor control feedback in compact embedded systems.
