Product details

Overview

MK20DN512VLQ10 from NXP Semiconductors (formerly Freescale) is a 32-bit ARM Cortex-M4 microcontroller with DSP extensions, designed for real-time embedded control in industrial and automotive applications. It operates at up to 100 MHz, integrates 512 KB on-chip flash memory (no FlexMemory), 128 KB RAM, dual 16-bit SAR ADCs with integrated PGA, two 12-bit DACs, and dual CAN 2.0B interfaces. It supports -40°C to +105°C operation and is packaged in a 144-pin LQFP (20 mm × 20 mm).

For engineers reviewing the MK20DN512VLQ10 datasheet, MK20DN512VLQ10 pinout, MK20DN512VLQ10 application, or MK20DN512VLQ10 equivalent, key selection considerations include its non-FlexMemory flash architecture, 144-LQFP thermal profile, dual CAN + USB OTG + SDHC interface set, low-power stop modes down to 2.1 µA (VLLS1), and compatibility with Kinetis SDK v2.x and MCUXpresso IDE.

Technical Context

The MK20DN512VLQ10 implements an ARM Cortex-M4 core with hardware DSP instructions and single-cycle MAC, enabling deterministic signal processing in motor control and sensor fusion. Its memory subsystem includes 512 KB of program flash (no FlexNVM/FlexRAM), 128 KB SRAM, and EzPort serial programming support - distinguishing it from X-series variants with FlexMemory.

System-level timing relies on a multi-source clock system: 3–32 MHz main crystal oscillator, 32 kHz RTC crystal input, and a multi-purpose clock generator (MCG) supporting FEI/FBI/BLPE/FEE modes. Peripheral clocking is managed via SIM module with configurable dividers, and power management includes six low-power modes (RUN, WAIT, VLPR, STOP, VLPS, LLS, VLLSx) with sub-µA retention capability.

Equivalent & Alternatives

The following parts are listed as comparable options for similar microcontroller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MKE15Z64VLH4	ARM Cortex-M0+, 64 KB flash, 8 KB RAM, no CAN, 48 MHz max - lower performance, smaller footprint (64-LQFP), no USB/SDHC.	Cost-sensitive consumer appliances requiring basic control only - insufficient for dual-CAN or USB-host use cases.	Select MK20DN512VLQ10 when dual CAN, USB OTG, or >100 MHz deterministic processing is required; MKE15Z64VLH4 suits simpler, lower-BOM-cost designs.
MIMXRT1021DAG4A	ARM Cortex-M7, 512 KB SRAM, no on-chip flash, 500 MHz, Ethernet, SEMC - higher performance, external flash dependency, larger package (196-BGA).	Edge AI inference or HMI-rich gateways needing >2000 DMIPS - overqualified for standalone motor control or CAN node roles.	MK20DN512VLQ10 offers integrated flash, mature Kinetis toolchain, and proven automotive qualification; MIMXRT1021DAG4A targets next-gen connected devices with external memory.

Compared with MKE15Z64VLH4, MK20DN512VLQ10 delivers 2.5× higher DMIPS, dual CAN, and USB OTG - essential for fieldbus integration. Versus MIMXRT1021DAG4A, it avoids external flash complexity and BGA assembly while meeting ASIL-B functional safety requirements via built-in MPU and watchdog features.

FAQ

What is the maximum operating frequency and core type of the MK20DN512VLQ10?

The MK20DN512VLQ10 features an ARM Cortex-M4 core with DSP extensions and operates at a maximum frequency of 100 MHz. It does not include a floating-point unit (FPU). This configuration delivers 125 DMIPS and supports single-cycle MAC operations, making it suitable for real-time signal processing in motor control and sensor fusion applications. The MK20DN512VLQ10 achieves this performance within its 1.71–3.6 V supply range and -40°C to +105°C temperature specification.

Does the MK20DN512VLQ10 include FlexMemory, and how does its memory architecture differ from other K20 variants?

No, the MK20DN512VLQ10 does not include FlexMemory. Its "N" in the part number denotes program flash only - specifically 512 KB of on-chip flash memory and 128 KB of SRAM. Unlike "X"-suffix variants (e.g., MK20DX256VLQ10), the MK20DN512VLQ10 lacks FlexNVM and FlexRAM, meaning it cannot dynamically allocate non-volatile storage for data logging or EEPROM emulation. This makes the MK20DN512VLQ10 optimal for fixed-function firmware deployments where code size dominates memory requirements.

Which communication interfaces are supported by the MK20DN512VLQ10, and are both CAN controllers fully functional?

The MK20DN512VLQ10 supports dual CAN 2.0B controllers, USB 2.0 Full/Low-Speed OTG with on-chip transceiver, six UARTs, three SPIs, two I²Cs, SDHC, and I²S. Both CAN modules are fully independent and functional - each with dedicated TX/RX pins, message buffers, and acceptance filtering. They do not support CAN FD. This dual-CAN capability enables applications such as automotive gateway functions or redundant industrial fieldbus networks, and is confirmed in the K20 Sub-Family Data Sheet Rev. 3 for the MK20DN512VLQ10.

What are the low-power capabilities of the MK20DN512VLQ10, and what is the lowest achievable current in stop mode?

The MK20DN512VLQ10 supports six low-power modes, including Very-Low-Leakage Stop modes (VLLS1–VLLS3). In VLLS1 mode at 3.0 V and -40°C to +25°C ambient, the typical current consumption is 2.1 µA - retaining RAM, RTC, and selected wakeup sources. At 105°C, VLLS1 current rises to 95.5 µA. These values are measured with all clocks disabled except the 32 kHz RTC oscillator and low-leakage wakeup unit, and are specified in Table 6 of the K20 Sub-Family Data Sheet Rev. 3 for the MK20DN512VLQ10.

Is the MK20DN512VLQ10 pin-compatible with other K20 family members, and what package does it use?

The MK20DN512VLQ10 uses a 144-pin LQFP package (20 mm × 20 mm, 0.5 mm pitch), identified by "LQ" in its part number. While it shares the same pinout with other K20 devices in the LQ package (e.g., MK20DX256VLQ10, MK20DN512VMD10), pin compatibility is limited to identical package types and does not extend across QFP vs. BGA variants. Signal multiplexing is consistent across the K20 Sub-Family, but users must verify peripheral enablement and clock gating in software - the MK20DN512VLQ10's absence of FlexMemory does not affect pin mapping.
