NXP Semiconductors MK30DX256VLK7

Overview

MK30DX256VLK7 from NXP Semiconductors (formerly Freescale) is a Kinetis K30 series ARM Cortex-M4 microcontroller with DSP extension, 256 KB flash, 64 KB RAM, and 80-pin LQFP package. It operates from 1.71–3.6 V across –40 to 105°C, integrates dual 16-bit SAR ADCs with PGA, CAN, four UARTs, and low-power timers - deployed in industrial motor control and smart sensor nodes.

For engineers reviewing the MK30DX256VLK7 datasheet, MK30DX256VLK7 pinout, MK30DX256VLK7 application, or MK30DX256VLK7 equivalent, key selection criteria include its 72 MHz max CPU frequency, FlexMemory support, segment LCD controller capability, real-time clock with battery backup, and verified VLLS1/VLLS2 sub-μA stop-mode current performance.

Technical Context

The MK30DX256VLK7 implements a multi-clock architecture with MCG supporting FEE/FBE/BLPE modes, enabling dynamic switching between high-performance (72 MHz) and ultra-low-power (4 MHz VLPR) operation. Its system-level power management includes eight low-power modes - from RUN to VLLS1 - coordinated by the low-leakage wakeup unit and software watchdog.

Peripherals are tightly integrated via a crossbar switch: two SPI, two I²C, four UART, I²S, CAN, and eight-channel PWM timer share bus arbitration with DMA servicing up to 63 request sources. Analog subsystems include dual ADCs with programmable gain amplifiers (x1–x64), 12-bit DAC, three comparators with internal 6-bit DACs, and voltage reference - all operating within the same 1.71–3.6 V supply range.

FAQ

What is the maximum operating frequency of the MK30DX256VLK7?

The MK30DX256VLK7 supports a maximum system and core clock frequency of 72 MHz in normal run mode. This is achieved using the Multipurpose Clock Generator (MCG) in FEE mode with an external crystal or oscillator. In Very-Low-Power Run (VLPR) mode, the maximum frequency is limited to 4 MHz to maintain sub-mA current consumption - a design trade-off enabling energy-efficient background processing.

Does the MK30DX256VLK7 include hardware encryption or secure boot features?

The MK30DX256VLK7 does not integrate hardware AES, SHA, or secure boot engines. Its security features are limited to a 128-bit unique identification number per chip and a hardware CRC module for data integrity verification. Secure firmware update and cryptographic operations must be implemented in software or offloaded to an external secure element - consistent with its positioning as a cost-optimized industrial MCU rather than a security-focused variant.

Can the MK30DX256VLK7 drive a segment LCD directly without external components?

Yes, the MK30DX256VLK7 includes an integrated segment LCD controller supporting up to 36 frontplanes and 8 backplanes (or 40 frontplanes and 4 backplanes), allowing direct connection to passive LCD glass. No external bias generator or driver IC is required - the controller provides programmable voltage steps, frame frequency control, and blinking support, making it suitable for industrial meters and medical displays.

What is the lowest achievable current consumption in stop mode for the MK30DX256VLK7?

In Very-Low-Leakage Stop Mode 1 (VLLS1), the MK30DX256VLK7 achieves 1.47 μA typical current at –40 to 25°C with RTC and RAM retention enabled. This value rises to 5.4 μA at 105°C. The device retains full register context and can wake within 73 μs - a critical specification for battery-powered endpoints requiring decades of operational life without maintenance.

Is the MK30DX256VLK7 pin-compatible with other K30 family members like MK30DX128VLK7?

Yes, the MK30DX256VLK7 shares the same 80-pin LQFP (LK) package and pinout with MK30DX128VLK7 and MK30DX64VLK7. All three variants use identical signal mapping, power/ground pin locations, and peripheral multiplexing - enabling hardware reuse across flash-size variants during design scaling or cost optimization without PCB revision.
