FAQ

What is the maximum operating frequency of the MK82FN256VDC15?

The MK82FN256VDC15 features an ARM Cortex-M4F core rated for up to 150 MHz operation. This frequency is achievable under specified voltage (1.71–3.6 V) and temperature (-40°C to 105°C) conditions with appropriate clock configuration (e.g., PEE mode using the PLL). At 150 MHz, the device delivers 196.2 CoreMark/MHz performance with full DSP and FPU support. MK82FN256VDC15 maintains timing compliance across its full industrial temperature range when operated within datasheet voltage and decoupling guidelines.

Does the MK82FN256VDC15 support secure boot from serial NOR flash?

Yes, the MK82FN256VDC15 supports secure boot from serial NOR flash via its dual QuadSPI interfaces with on-the-fly (OTF) AES128/AES256 decryption and execute-in-place (XIP) capability. The LP Trusted Cryptography (LTC) engine decrypts flash contents transparently during read access, allowing authenticated and encrypted firmware to execute directly without loading into RAM. MK82FN256VDC15 requires proper key provisioning and flash image formatting per NXP's K82 Security Reference Manual to enable this feature.

What package type and pin count does the MK82FN256VDC15 use?

The MK82FN256VDC15 is packaged in a 121-pin XFBGA (8 mm × 8 mm, 0.65 mm pitch) with exposed thermal pad. This package provides 87 general-purpose I/O pins, plus dedicated power, ground, clock, reset, and debug signals. MK82FN256VDC15's XFBGA footprint is optimized for high-density PCB layouts and thermal performance in space-constrained industrial modules, and it complies with JEDEC JESD22-A103 for moisture sensitivity level 3 handling.

Which low-power modes are available on the MK82FN256VDC15, and what is the lowest current draw?

The MK82FN256VDC15 offers seven low-power modes, including VLLS0 (Very-Low-Leakage Stop Mode 0) with POR detection enabled, which achieves a typical current draw of 0.62 μA at 25°C and 3.0 V. In VLLS0, the RTC remains active in its independent 3.3 V domain, and wake-up can occur via RTC alarm, external pin, or low-power timer. MK82FN256VDC15 maintains full register retention and secure state in all stop modes, with recovery times as low as 5.3 μs from VLPS to RUN mode.

What analog peripherals are integrated into the MK82FN256VDC15?

The MK82FN256VDC15 integrates a 16-bit SAR ADC (up to 1 MSPS), one 12-bit DAC, two 6-bit DACs (embedded in analog comparators), two analog comparators with programmable reference inputs, and a 1.2 V internal voltage reference. These peripherals support precision sensor interfacing, closed-loop control, and waveform generation. MK82FN256VDC15's ADC features hardware averaging and programmable oversampling, while its DACs enable fast analog output for calibration or actuator drive without external components.
