FAQ

What is the maximum operating frequency of the MK20DN512ZVLQ10R?

The MK20DN512ZVLQ10R operates at a maximum CPU frequency of 100 MHz, enabled by its ARM Cortex-M4 core with DSP extensions. This frequency is supported across the full -40°C to +105°C ambient temperature range and 1.71–3.6 V supply voltage, with internal clock generation via the MCG module configured in FEE mode. The MK20DN512ZVLQ10R achieves 125 DMIPS at this speed, validated per Dhrystone 2.1 benchmark.

Does the MK20DN512ZVLQ10R support USB On-The-Go functionality?

Yes, the MK20DN512ZVLQ10R integrates a full-/low-speed USB On-The-Go controller with an on-chip transceiver, supporting device, host, and OTG roles without external PHY components. It complies with USB 2.0 specification and includes dedicated USB voltage regulator (VREG), D+ pull-up control, and suspend/resume signaling. The MK20DN512ZVLQ10R's USB interface is accessible via dedicated USB_DP and USB_DM pins in its 144-pin LQFP package.

What analog peripherals are integrated into the MK20DN512ZVLQ10R?

The MK20DN512ZVLQ10R integrates two 16-bit SAR ADCs with programmable gain amplifiers (up to ×64), two 12-bit DACs, three analog comparators (each with a 6-bit DAC and programmable reference input), and a precision voltage reference module. These peripherals support simultaneous sampling, hardware-triggered conversions, and flexible routing to internal modules like the PDB and DMA - all confirmed in the K20 Sub-Family Data Sheet Rev. 7 for the MK20DN512ZVLQ10R variant.

Is the MK20DN512ZVLQ10R qualified for automotive applications?

The MK20DN512ZVLQ10R is qualified for extended temperature operation (-40°C to +105°C) and meets AEC-Q100 stress test requirements for Grade 2 devices. Its dual CAN 2.0B controllers, hardware CRC, memory protection unit, and fail-safe peripherals such as external watchdog monitor make it suitable for automotive body electronics, gateway modules, and chassis control units - though final qualification depends on end-system validation per ISO 26262 ASIL-B requirements.

What package type does the MK20DN512ZVLQ10R use?

The MK20DN512ZVLQ10R uses a 144-pin LQFP package (20 mm × 20 mm), identified by the "LQ" suffix in its part number per NXP's K20 ordering guide. This package features exposed thermal pad, standard 0.5 mm pitch, and is rated MSL3 per J-STD-020. Pin assignments follow the K20 Signal Multiplexing and Pin Assignments document, with verified mappings for VDD/VSS domains, crystal inputs, USB, CAN, and GPIO functions.
