NXP Semiconductors MK20DN512ZVLK10

Overview

MK20DN512ZVLK10 from NXP (formerly Freescale) is a 32-bit ARM Cortex-M4 microcontroller with DSP extensions, operating at up to 100 MHz, featuring 512 KB on-chip flash memory (no FlexMemory), 128 KB RAM, and industrial temperature range (–40 to 105°C). It integrates dual 16-bit SAR ADCs with PGA, 12-bit DAC, two CAN interfaces, USB OTG, and low-power timers - deployed in motor control and industrial sensor gateway applications.

For engineers reviewing the MK20DN512ZVLK10 datasheet, MK20DN512ZVLK10 pinout, MK20DN512ZVLK10 application, or MK20DN512ZVLK10 equivalent, key selection considerations include its 80-pin LQFP package, 100 MHz core clock, dual CAN support, 512 KB flash-only memory architecture, and verified operation across –40 to 105°C ambient conditions.

Technical Context

The MK20DN512ZVLK10 implements an ARM Cortex-M4 core with hardware DSP instructions and no FPU, executing at 100 MHz via a multi-source clock system including 3–32 MHz crystal oscillator and 32 kHz RTC oscillator. Its memory subsystem comprises 512 KB program flash (non-FlexMemory), 128 KB SRAM, and no FlexNVM/FlexRAM - distinguishing it from X-suffix variants.

Peripherals include two Controller Area Network (CAN) modules compliant with ISO 11898-1, four UARTs, two I²C, two SPI, SDHC, I²S, USB full-/low-speed OTG with on-chip transceiver, and eight-channel PWM timer with quadrature decode capability - all accessible through multiplexed I/O pins on the 80-LQFP package.

FAQ

What is the maximum operating frequency of the MK20DN512ZVLK10?

The MK20DN512ZVLK10 operates at a maximum CPU frequency of 100 MHz, achieved using its ARM Cortex-M4 core with DSP extensions. This frequency is supported across the full industrial temperature range (–40 to 105°C) when supplied within the 1.71–3.6 V voltage range and with appropriate clock source configuration (e.g., 32 MHz crystal + PLL). The MK20DN512ZVLK10 delivers 125 DMIPS at this speed, enabling deterministic execution of real-time control algorithms.

Does the MK20DN512ZVLK10 include FlexMemory?

No, the MK20DN512ZVLK10 does not include FlexMemory. Its part number suffix "N" explicitly denotes "program flash only", confirming 512 KB of main program flash memory with no FlexNVM or FlexRAM. This distinguishes it from "X"-suffix variants like MK20DX256ZVLK10, which integrate FlexMemory for EEPROM emulation and configurable data storage. The MK20DN512ZVLK10 relies on standard flash sectors for both code and data storage.

What package type is used for the MK20DN512ZVLK10?

The MK20DN512ZVLK10 uses an 80-pin LQFP package (12 mm × 12 mm), identified by the "LK" package code in its part number. This RoHS-compliant package features exposed thermal pad and moisture sensitivity level 3, requiring bake-before-reflow handling per J-STD-020. Pin assignments follow K20 family signal multiplexing rules documented in the K20 Sub-Family Data Sheet Rev. 7, with dedicated VDD/VSS and VDDA/VSSA pairs for noise isolation.

How many CAN interfaces does the MK20DN512ZVLK10 support?

The MK20DN512ZVLK10 integrates two independent Controller Area Network (CAN) modules compliant with ISO 11898-1, supporting bit rates up to 1 Mbps. Each module includes full CAN protocol handling (message filtering, FIFO buffering, error management) and dedicated TX/RX pins mapped to specific LQFP pins. These interfaces enable dual-bus architectures - for example, one for vehicle diagnostics (OBD-II) and another for actuator coordination - without external CAN controllers.

Is the MK20DN512ZVLK10 suitable for automotive applications?

Yes, the MK20DN512ZVLK10 is qualified for automotive applications, evidenced by its –40 to 105°C operating temperature range (denoted by "V" in the part number), AEC-Q100 stress test compliance (per Freescale/NXP documentation), and integrated features such as dual CAN, hardware CRC, memory protection unit, and fail-safe reset mechanisms. It is commonly deployed in body control modules, HVAC controllers, and gateway ECUs where functional safety (ASIL-B capable with software mitigation) and long-term supply stability are required.
