FAQ

What is the maximum operating frequency of the MK20DN512ZAB10R?

The MK20DN512ZAB10R operates at up to 100 MHz using its ARM Cortex-M4 core with DSP extension. This frequency is achievable with proper decoupling, stable 3.3 V supply, and correct clock configuration (e.g., MCG in FEE mode). At this speed, the MK20DN512ZAB10R delivers 125 DMIPS and supports real-time control loops with sub-microsecond interrupt latency.

Does the MK20DN512ZAB10R include USB functionality?

Yes, the MK20DN512ZAB10R integrates a full-/low-speed USB On-The-Go controller with an on-chip transceiver. It supports USB 2.0 compliance, device/host/OTG roles, and requires only external 1.5 kΩ pull-up on USB_DP for full-speed enumeration. No external PHY is needed, reducing BOM count and PCB area for the MK20DN512ZAB10R design.

What analog peripherals are integrated into the MK20DN512ZAB10R?

The MK20DN512ZAB10R integrates two independent 16-bit SAR ADCs, each with a programmable gain amplifier (PGA) supporting gains from ×1 to ×64; three analog comparators (each with a 6-bit DAC and programmable reference); two 12-bit DACs; and a precision voltage reference module. These enable direct high-fidelity analog signal acquisition and conditioning without external signal-chain components in the MK20DN512ZAB10R application.

Is the MK20DN512ZAB10R qualified for automotive applications?

The MK20DN512ZAB10R is specified for –40°C to +105°C ambient operation and includes automotive-grade features such as dual CAN 2.0B controllers, hardware CRC, memory protection unit (MPU), and robust ESD ratings (±2 kV HBM). While not AEC-Q100 certified out-of-box, it is widely deployed in automotive body control modules and infotainment gateways where system-level qualification is performed - confirming suitability for non-safety-critical automotive use cases of the MK20DN512ZAB10R.

What package type does the MK20DN512ZAB10R use?

The MK20DN512ZAB10R uses a 144-pin LQFP package (20 mm × 20 mm, 0.5 mm pitch), designated by the "LQ" suffix in its part number. This package supports standard surface-mount assembly, offers excellent thermal dissipation for industrial environments, and provides full access to all GPIO, peripheral, and power pins required for complex embedded designs using the MK20DN512ZAB10R.
