MK21FN1M0VMD12

The NXP Semiconductors MK21FN1M0VMD12 is a high-performance microcontroller from the Kinetis K21F family, designed for cost-sensitive applications requiring low-power operation and USB connectivity. It is built around a 120 MHz ARM Cortex-M4 core with DSP instructions and a Floating Point Unit (FPU), delivering 1.25 Dhrystone MIPS per MHz.

This device features up to 1 MB of program flash memory and 128 KB of SRAM. It includes a comprehensive set of peripherals such as a USB full-/low-speed On-the-Go controller, Controller Area Network (CAN) module, multiple SPI, I2C, and UART modules, and an I2S module. For analog functions, it provides two 16-bit SAR ADCs and two 12-bit DACs.

Security features include hardware CRC, tamper detection, secure storage, a hardware random-number generator, and hardware encryption. The microcontroller operates within a voltage range of 1.71V to 3.6V and has an operating temperature range of -40°C to 105°C (TA). It is supplied in a 144-MAPBGA (13x13) package, suitable for surface mounting.

Additional capabilities include multiple low-power modes, a DMA controller, and various timer modules for PWM and motor control applications. The device also supports internal oscillators, PLL, and FLL for flexible clock management.
