NXP Semiconductors MK10DX256VLL7

Overview

MK10DX256VLL7 from NXP (formerly Freescale) is a 32-bit ARM Cortex-M4 microcontroller with DSP extension and single-precision FPU, operating at 72 MHz. It integrates 256 KB flash, 32 KB FlexNVM (configurable as EEPROM), 64 KB SRAM, 16-bit ADC, 12-bit DAC, and dual CAN interfaces. It targets low-power industrial sensing and control applications such as HVAC controllers and remote sensor nodes.

For engineers reviewing the MK10DX256VLL7 datasheet, MK10DX256VLL7 pinout, MK10DX256VLL7 application, or MK10DX256VLL7 equivalent, key selection criteria include its 72 MHz Cortex-M4 core with FPU, 32 KB FlexMemory for EEPROM emulation, dual CAN 2.0B support, ultra-low-power stop mode (<500 nA), and LQFP-100 package compatibility with industrial temperature range (–40°C to +105°C).

Technical Context

The MK10DX256VLL7 implements an ARM Cortex-M4 core with hardware floating-point unit and DSP instruction set, enabling real-time signal processing in resource-constrained embedded systems. It features a crossbar switch architecture supporting concurrent multi-master bus accesses, and includes a 32-channel DMA controller to offload CPU bandwidth during peripheral transfers.

Its mixed-signal subsystem integrates a 16-bit, 1 MSps ADC with programmable gain amplifier (PGA), a 12-bit DAC, and analog comparators - all operable in low-power modes. Clock management includes PLL, FLL, and multiple internal/external oscillators, with flexible clock gating per peripheral to minimize dynamic power.

FAQ

What is the maximum operating frequency of the MK10DX256VLL7?

The MK10DX256VLL7 operates at a maximum core frequency of 72 MHz using its internal PLL or FLL. This frequency is fully supported across the industrial temperature range (–40°C to +105°C) and enables deterministic real-time execution of control algorithms, communication stacks, and signal processing tasks without thermal throttling. The MK10DX256VLL7 achieves this while maintaining sub-200 µA/MHz active current consumption.

Does the MK10DX256VLL7 include hardware cryptographic acceleration?

No, the MK10DX256VLL7 does not integrate a Cryptographic Acceleration Unit (CAU). That feature is present in the MK11DX and MK12DX series (e.g., MK11DX256AVLL5). The MK10DX256VLL7 relies on software-based cryptography libraries for AES, SHA, or DES operations. For secure boot or encrypted communication, external secure elements or software optimization are required - unlike later Kinetis families where CAU is standard.

What package type and pin count does the MK10DX256VLL7 use?

The MK10DX256VLL7 uses a 100-pin LQFP package (14 mm × 14 mm, 0.5 mm pitch), designated by the "LL" suffix in the part number. This package is pin-compatible with other MK10DXx256Vxx7 variants in the same family and supports full peripheral mapping including dual CAN, multiple UARTs, and all ADC/DAC channels. It is RoHS-compliant and rated for industrial temperature operation.

Can the MK10DX256VLL7 execute code while writing to FlexMemory?

Yes, the MK10DX256VLL7 supports concurrent code execution and FlexMemory programming due to its dual-bank flash architecture. While one bank is being erased or programmed (e.g., updating calibration data in FlexNVM), the CPU can continue executing from the other bank. This capability enables safe over-the-air firmware updates and runtime parameter storage without system interruption - a key requirement for MK10DX256VLL7 deployments in unattended industrial equipment.

What is the role of the Programmable Gain Amplifier (PGA) in the MK10DX256VLL7?

The MK10DX256VLL7 integrates a hardware-programmable gain amplifier (PGA) that boosts weak analog sensor signals (e.g., from thermocouples or bridge sensors) before ADC conversion. With selectable gains of 1×, 2×, 4×, 8×, 16×, 32×, or 64×, the PGA enables direct digitization of µV-level inputs without external op-amps. This reduces bill-of-materials cost and PCB area while improving noise immunity - a core advantage of the MK10DX256VLL7 in precision measurement applications.
