NXP Semiconductors MK30DX64VLH7

Overview

MK30DX64VLH7 from NXP Semiconductors (formerly Freescale) is a Kinetis K30-series 32-bit ARM Cortex-M4 microcontroller with DSP extensions, 64 KB flash, 16 KB SRAM, and 64-pin LQFP package. It operates from 1.71–3.6 V across –40 to 105°C, integrates dual 16-bit SAR ADCs with PGA, 12-bit DAC, CAN, USB, multiple UART/I²C/SPI, and supports low-power motor control in industrial automation systems.

For engineers reviewing the MK30DX64VLH7 datasheet, MK30DX64VLH7 pinout, MK30DX64VLH7 application, or MK30DX64VLH7 equivalent, key selection criteria include its 72 MHz max CPU frequency, 64-pin LQFP thermal performance at 105°C ambient, integrated FlexMemory for EEPROM emulation, and verified CAN 2.0B compliance in automotive body control modules.

Technical Context

The MK30DX64VLH7 implements a multi-layer AHB bus architecture with separate instruction/data buses to the core, enabling concurrent flash access and execution. Its MCG clock generator supports FEE/FBE/BLPE modes with internal reference trimming, delivering stable 72 MHz system clock from 3–32 MHz crystal input or internal 32 kHz oscillator.

Power management includes six low-power modes (VLPR/VLPW/STOP/VLPS/LLS/VLLS), with VLLS1 consuming just 1.47 µA at –40 to 25°C. The device uses a unified memory map with 32-bit addressing, and its DMA controller supports scatter-gather transfers across all peripherals without CPU intervention.

FAQ

What is the maximum operating frequency of the MK30DX64VLH7?

The MK30DX64VLH7 supports a maximum system clock frequency of 72 MHz, achieved using the MCG's FEE mode with an external 3–32 MHz crystal. This frequency is validated across the full –40 to 105°C temperature range and 1.71–3.6 V supply, enabling sub-microsecond interrupt response and precise 1 Mbps CAN timing. The MK30DX64VLH7 maintains this performance without requiring external PLL components or complex clock tree design.

Does the MK30DX64VLH7 include hardware security features?

Yes, the MK30DX64VLH7 includes a hardware CRC module supporting IEEE-802.3 and CRC-16-CCITT polynomials for fast firmware integrity checks, plus a factory-programmed 128-bit unique identification number for device authentication. It does not include cryptographic accelerators or secure boot ROM, so external secure elements are required for TLS or code signing. The MK30DX64VLH7 relies on these features for basic anti-cloning and image validation in industrial firmware updates.

Can the MK30DX64VLH7 operate without an external crystal?

Yes, the MK30DX64VLH7 can operate using its internal 32.768 kHz RTC oscillator or internal 4 MHz IRC for low-frequency applications, but full 72 MHz performance requires an external 3–32 MHz crystal connected to EXTAL/XTAL pins. The MCG supports bypass mode and internal reference trimming to maintain ±2% frequency accuracy without crystal - however, USB and CAN compliance require external crystal for jitter control. The MK30DX64VLH7's clock system is fully functional without external crystal only in non-USB/CAN use cases.

What analog peripherals are integrated into the MK30DX64VLH7?

The MK30DX64VLH7 integrates two independent 16-bit SAR ADCs (each with programmable gain amplifier up to ×64), a 12-bit DAC, three analog comparators (each with integrated 6-bit DAC and programmable reference), and a precision voltage reference. These peripherals share a common analog supply domain (VDDA/VSSA) with strict 0.1 V differential tolerance. The MK30DX64VLH7 supports simultaneous sampling and hardware-triggered conversions, enabling synchronized current/voltage measurement in motor control applications.

Is the MK30DX64VLH7 pin-compatible with other K30 family members?

No, the MK30DX64VLH7 is not pin-compatible with other K30 variants due to differing peripheral mappings and signal multiplexing. While all LH-package K30 parts share the same 64-pin LQFP mechanical footprint, the MK30DX64VLH7 has unique pin assignments for CAN, USB, and LCD functions compared to MK30DX128VLH7 or MK30DX256VLH7. PCB layout must be verified against the specific MK30DX64VLH7 pinout table - direct substitution without board revision is not supported. The MK30DX64VLH7 requires dedicated layout validation even within the same package family.
