FAQ

What is the maximum operating frequency and core type of the MK53DX256CMD10?

The MK53DX256CMD10 features an ARM Cortex-M4 core with DSP extensions (no FPU) and operates at a maximum frequency of 100 MHz. This delivers 125 DMIPS performance and is validated across the full temperature range (–40°C to +85°C) under 1.71–3.6 V supply conditions. The MK53DX256CMD10 uses the MCG clock generator with PLL to achieve stable 100 MHz operation from a 3–32 MHz crystal source.

Does the MK53DX256CMD10 include hardware cryptographic acceleration?

Yes, the MK53DX256CMD10 integrates dedicated hardware modules for AES-128/256, DES/3DES, SHA-1/256, MD5, CRC-32, and a true random number generator (TRNG). These accelerate cryptographic operations without CPU intervention - enabling secure boot, firmware signature verification, and encrypted data storage in the FlexNVM. The MK53DX256CMD10 also includes a 128-bit unique chip ID for device authentication.

What analog peripherals are integrated into the MK53DX256CMD10?

The MK53DX256CMD10 integrates two independent 16-bit SAR ADCs (each with programmable gain amplifier up to ×64), two 12-bit DACs, two operational amplifiers, three analog comparators (each with integrated 6-bit DAC and programmable reference), two transimpedance amplifiers, and a precision voltage reference. These enable high-fidelity sensor signal conditioning, closed-loop analog control, and metrology-grade measurements - all without external components.

What package and pin count does the MK53DX256CMD10 use?

The MK53DX256CMD10 is housed in a 144-pin LQFP package (20 mm × 20 mm, 0.5 mm pitch), designated by the "LQ" suffix in its part number format. This package provides full access to all peripherals including Ethernet MII signals, USB DP/DM, multiple UART/SPI/I²C interfaces, ADC/DAC pins, and FlexBus external memory interface - verified in the official K53 Sub-Family Data Sheet Rev. 3.

How does the FlexMemory architecture work in the MK53DX256CMD10?

The MK53DX256CMD10 implements FlexMemory comprising 256 KB FlexNVM and 4 KB FlexRAM. FlexNVM behaves like EEPROM - supporting byte-level writes, wear leveling, and configurable sector sizes - while FlexRAM serves as fast, nonvolatile data cache. This eliminates need for external EEPROM and simplifies firmware update handling. The MK53DX256CMD10's FlexMemory is managed via dedicated FTFL controller registers and requires no external hardware.
