NXP Semiconductors MK30DX128VLL7

Overview

MK30DX128VLL7 from NXP Semiconductors (formerly Freescale) is a Kinetis K30 Series ARM Cortex-M4 microcontroller with DSP extension, 128 KB flash, 16 KB SRAM, and 72 MHz maximum CPU frequency. It integrates dual 16-bit SAR ADCs with PGA, 12-bit DAC, CAN, five UARTs, two I²C, two SPI, I²S, RTC, and segment LCD controller. Designed for industrial control and low-power HMI applications requiring robust analog integration and real-time communication.

For engineers reviewing the MK30DX128VLL7 datasheet, MK30DX128VLL7 pinout, MK30DX128VLL7 application, or MK30DX128VLL7 equivalent, key selection considerations include its -40°C to 105°C extended temperature grade, 1.71–3.6 V supply range, VLLS3 stop-mode current of ≤41.9 µA at 105°C, and LQFP-100 package with validated 100-pin multiplexed I/O mapping.

Technical Context

The MK30DX128VLL7 implements an ARM Cortex-M4 core with DSP instructions and no FPU, operating up to 72 MHz via the Multipurpose Clock Generator (MCG) in FEE mode. Its memory subsystem includes 128 KB on-chip flash with FlexMemory support, 16 KB SRAM, and hardware CRC acceleration for firmware integrity verification.

Peripheral architecture features a 16-channel DMA controller supporting 63 request sources, eight-channel PWM timer with motor control capability, two quadrature decoder timers, and a low-leakage wakeup unit enabling sub-µA stop modes. The analog subsystem integrates two independent 16-bit SAR ADCs-each with programmable gain amplifier (up to ×64), 12-bit DAC, three analog comparators with internal 6-bit DACs, and voltage reference.

FAQ

What is the maximum operating frequency of the MK30DX128VLL7?

The MK30DX128VLL7 operates at a maximum CPU frequency of 72 MHz, achieved using the Multipurpose Clock Generator (MCG) in FEE mode with an external 3–32 MHz crystal. This frequency is fully supported across the full -40°C to 105°C ambient temperature range and 1.71–3.6 V supply voltage, as verified in the K30 Sub-Family Data Sheet Rev. 3.

Does the MK30DX128VLL7 include a hardware floating-point unit (FPU)?

No, the MK30DX128VLL7 implements an ARM Cortex-M4 core with DSP extensions but does not include a hardware FPU. The 'D' in the part number denotes Cortex-M4 with DSP, whereas 'F' would indicate inclusion of the FPU. Signal processing must use integer or fixed-point arithmetic optimized for the DSP instruction set.

What package type and pin count does the MK30DX128VLL7 use?

The MK30DX128VLL7 uses a 100-pin LQFP package (14 mm × 14 mm, 0.5 mm pitch), designated by 'LL' in the part number. Pin assignments are documented in Section 8.2 ("K30 Pinouts") of the K30 Sub-Family Data Sheet, with full signal multiplexing details in Section 8.1.

Can the MK30DX128VLL7 operate from a single 1.8 V supply?

Yes, the MK30DX128VLL7 supports operation from 1.71 V to 3.6 V, including 1.8 V nominal rails. At 1.8 V, it delivers 21.5 mA typical run-mode current (all peripherals disabled) and maintains full functionality including ADC, DAC, and CAN, as specified in Table 6 of the datasheet.

Is the MK30DX128VLL7 qualified for automotive applications?

The MK30DX128VLL7 is not AEC-Q100 qualified. It is rated for industrial temperature (-40°C to +105°C) and intended for industrial, medical, and building automation applications. For automotive use, NXP recommends the K32L2B series or S32K1xx families, which undergo full AEC-Q100 stress testing and qualification.
