FAQ

What is the maximum operating frequency of the MK11DX128AVMC5?

The MK11DX128AVMC5 operates at a maximum system clock frequency of 50 MHz, achieved via its ARM Cortex-M4 core with DSP extension. This frequency is supported across the full operating voltage range (1.71–3.6 V) and temperature range (–40 to 105°C), enabling deterministic execution of real-time control algorithms and communication stacks. The MK11DX128AVMC5 achieves 1.25 Dhrystone MIPS per MHz, delivering 62.5 DMIPS at full speed.

Does the MK11DX128AVMC5 include hardware encryption capabilities?

Yes, the MK11DX128AVMC5 integrates dedicated hardware acceleration for DES, 3DES, AES (128/192/256-bit), MD5, SHA-1, and SHA-256 cryptographic functions. These modules operate independently of the CPU core, allowing secure firmware updates, encrypted communication, and secure boot verification without compromising real-time performance. The MK11DX128AVMC5 also includes a hardware random-number generator and tamper-detection circuitry for comprehensive security compliance.

What memory architecture does the MK11DX128AVMC5 use for nonvolatile data storage?

The MK11DX128AVMC5 employs FlexMemory architecture, consisting of 64 KB FlexNVM and 4 KB FlexRAM. This enables true EEPROM emulation with byte-level erase, >1 million write cycles, and wear-leveling managed entirely in hardware. Unlike standard flash, FlexNVM allows persistent storage of calibration data, device configuration, and firmware update metadata without requiring external serial EEPROM. The MK11DX128AVMC5 leverages this for robust field-upgradeable systems.

What analog peripherals are integrated into the MK11DX128AVMC5?

The MK11DX128AVMC5 integrates a 16-bit SAR ADC (up to 1 MSPS), dual 12-bit DACs, two analog comparators each with a built-in 6-bit DAC and programmable reference input, and a precision voltage reference module. These peripherals support high-fidelity sensor acquisition, analog actuator control, and comparator-based threshold detection-all with hardware-triggered synchronization via the programmable delay block. The MK11DX128AVMC5's analog subsystem meets industrial-grade accuracy requirements without external signal conditioning.

What low-power modes are supported by the MK11DX128AVMC5, and what is the lowest current draw?

The MK11DX128AVMC5 supports seven low-power modes including VLPR, VLPS, LLS, and four VLLS variants. In VLLS0 mode with POR detect disabled, it draws just 0.359 μA at –40°C, retaining full RAM content and RTC operation. At 105°C, VLLS0 current rises to 15.20 μA - still enabling multi-year battery life in intermittent-sensing applications. The MK11DX128AVMC5 achieves this via dedicated low-leakage wakeup units, clock gating, and optimized power gating across all domains.
