NXP Semiconductors MK30DX64VLK7

Overview

MK30DX64VLK7 from NXP Semiconductors (formerly Freescale) is a Kinetis K30 Series ARM Cortex-M4 microcontroller with DSP extension, 64 KB flash, 16 KB RAM, operating at up to 72 MHz, supporting industrial temperature range (–40 to 105°C), and featuring dual 16-bit SAR ADCs with integrated PGA, CAN, UART, I²C, SPI, and real-time clock - deployed in motor control and smart sensor edge nodes.

For engineers reviewing the MK30DX64VLK7 datasheet, MK30DX64VLK7 pinout, MK30DX64VLK7 application, or MK30DX64VLK7 equivalent, key selection considerations include its 80-pin LQFP package, 72 MHz max CPU frequency, –40 to 105°C extended temperature rating, FlexMemory support, and integrated touch-sensing interface for low-power HMI designs.

Technical Context

The MK30DX64VLK7 implements a 32-bit ARM Cortex-M4 core with DSP instructions and no FPU, paired with a multi-purpose clock generator supporting crystal oscillators at 3–32 MHz and 32 kHz. Its memory subsystem includes 64 KB program flash with FlexMemory partitioning capability and 16 KB SRAM.

Peripherals are organized around a high-speed AHB bus matrix and APB bridges: two 16-bit ADCs each with programmable gain amplifier (up to ×64), one 12-bit DAC, three analog comparators with internal 6-bit DACs, eight-channel PWM timer, two quadrature decoder timers, four UARTs, two I²C modules, two SPI modules, one I²S module, and one CAN 2.0B controller - all operating within 1.71–3.6 V supply range.

FAQ

What is the maximum operating frequency of the MK30DX64VLK7?

The MK30DX64VLK7 operates at a maximum CPU frequency of 72 MHz, achieved using the internal MCG clock generator in FEE mode with an external 8 MHz crystal and PLL multiplication. This frequency is validated across the full –40 to 105°C temperature range and 1.71–3.6 V supply voltage, enabling deterministic real-time execution for motor control and communication stacks. The MK30DX64VLK7 maintains this performance without requiring external clock sources beyond the main crystal.

Does the MK30DX64VLK7 support FlexMemory, and how is it configured?

Yes, the MK30DX64VLK7 supports FlexMemory - a configurable portion of its 64 KB flash that can be re-purposed as emulated EEPROM. Configuration is performed via the FTFL_FLEXRAMBLOCK register during initialization, allowing dynamic allocation between code storage and non-volatile data logging. This capability eliminates the need for external EEPROM in applications such as energy meter tamper logs or motor calibration storage, and is confirmed in the K30 Sub-Family Data Sheet Rev. 3 section 6.4.1.

What analog peripherals are integrated into the MK30DX64VLK7?

The MK30DX64VLK7 integrates two independent 16-bit SAR ADCs, each with a programmable gain amplifier (PGA) offering gains up to ×64, a 12-bit DAC, three analog comparators (each with an integrated 6-bit DAC and programmable reference), and a precision voltage reference module. These peripherals support simultaneous sampling, hardware-triggered conversions, and low-noise operation - verified in sections 6.6.1–6.6.4 of the K30 Sub-Family Data Sheet. The MK30DX64VLK7 uses dedicated VDDA/VSSA pins to maintain analog integrity.

Is the MK30DX64VLK7 pin-compatible with other K30 family members?

The MK30DX64VLK7 shares the same 80-pin LQFP (LK) package footprint and pin assignment with other K30 variants including MK30DX128VLK7 and MK30DX256VLK7, as defined in section 8.2 "K30 Pinouts" of the K30 Sub-Family Data Sheet. However, functional pin mapping (e.g., peripheral availability on specific pins) may differ due to silicon configuration - for example, certain ADC channels or TSI inputs are not present on all variants. Always verify signal multiplexing per device using the K30 Signal Multiplexing table.

What low-power modes does the MK30DX64VLK7 support, and what are their typical current draws?

The MK30DX64VLK7 supports seven low-power modes, including VLPR, VLPW, STOP, VLPS, LLS, VLLS1, VLLS2, and VLLS3. At 3.0 V and –40 to 25°C, typical currents are: VLPR = 0.996 mA, VLPS = 5.9 μA, LLS = 2.6 μA, VLLS3 = 1.9 μA. These values are measured with RTC enabled and RAM retained, as specified in Table 6 of the K30 Sub-Family Data Sheet Rev. 3. The MK30DX64VLK7 achieves these figures using dedicated low-leakage wakeup units and optimized clock gating.
