MK30DX128VLL7 概要
A Kinetis K-series microcontroller is a Cortex-M4 based system-on-chip that integrates Flash, SRAM, mixed-signal analog, timers, communication peripherals and various human-machine-interface blocks (LCD, USB, CAN, segments) onto a single die. Within the broader Kinetis portfolio, K30 sits between the cost-optimized K10 and the higher-performance K40/K60/K70 families, sharing peripherals, tool chains and the same enablement ecosystem. The MK30DX128VLL7 includes hardware FPU, 16-bit ADC, 12-bit DAC, comparators and segment-LCD drive.
Key features of the MK30DX128VLL7 include 72 MHz Cortex-M4 core with single-precision FPU, 128 KB Flash, 32 KB SRAM, segment LCD driver (up to 8x40 or 8x32 segments depending on package), USB 2.0 full-speed with on-chip transceiver, CAN, I2C, SPI, UART, 12-bit SAR ADC, 12-bit DAC, low-power run/wait/stop modes with VLLS retention. The LQFP-100 package exposes the full peripheral set, making it suited for cost-sensitive HMI designs.
The architecture uses a Harvard bus with separate code and data paths and an integrated FPU; this allows deterministic interrupt latency while sustaining DSP-class math throughput for control loops. Internal high-accuracy reference and trim features reduce BOM cost and improve ADC accuracy.
Typical applications include low-cost segment-LCD human-machine-interface panels, smart metering, home appliances, industrial control panels, building automation and white-goods user interfaces. The Cortex-M4 plus FPU enables these filters to be implemented efficiently with deterministic execution.
Designers should plan for a 2.7-3.6V supply, a 32.768 kHz watch crystal for accurate RTC, and SWsupport all decoupling. Cap included PCB near the MCU. The datasheet defines maximum pin ratings - exceeding them causes permanent damage.

主な用途
MK30DX128VLL7 の用途: 6 件s: Smart Meter Segment LCD HMI, Home Appliance User Interface Panels, Industrial Control Panels and HMI, Building Automation Thermostats, White Goods Motor-Plus-Display Boards, Medical Segment-LCD Devices.
Smart Meter Segment LCD HMI
The MK30DX128VLL7's integrated SLCD controller (up to 8x40 segments) drives utility-meter displays without external LCD drivers, reducing BOM cost and PCB area for residential electricity, water and gas meters. The 72 MHz Cortex-M4 with FPU computes tariff logic and power-quality metrics while the 32 KB SRAM buffers logging samples. Low-power VLLS modes below 5 uA extend battery life; on-chip 12-bit ADC accurately samples CT/PT inputs. Pin compatibility with the 100-LQFP layout eases mechanical fit in standard meter enclosures.
おすすめ
Home Appliance User Interface Panels
The MK30DX128VLL7 drives segment-LCD user interfaces on washing machines, dishwashers, ovens and refrigerators, integrating the MCU and SLCD bias network on a single chip. The 72 MHz performance handles capacitive-touch decoding, motor-control supervisory logic and segment refresh with deterministic interrupt latency from the Cortex-M4 NVIC. USB device mode supports diagnostic/service interfaces without adding a separate bridge IC. The 100-LQFP package is widely accepted in appliance factories and supports both leaded and lead-free reflow.
おすすめ
Industrial Control Panels and HMI
The MK30DX128VLL7 powers segment-LCD industrial control panels where deterministic real-time response, segment display and CAN connectivity are required in one device. The hardware FPU executes PID loops and signal-processing math at 72 MHz without CPU stalls, while the segment LCD displays setpoints, alarms and status to operators. Integrated FlexCAN enables panel-to-PLC networks on factory floors; USB device mode permits firmware updates via service ports. The 100-LQFP package provides generous pin count for parallel I/O expansion in panel wiring.
おすすめ
Building Automation Thermostats
Commercial and residential thermostats use the MK30DX128VLL7 to drive segment-LCD temperature displays, run PID climate control and read NTC sensors via the 12-bit ADC. The integrated FPU executes floating-point thermostat algorithms efficiently while VLLS power modes drop quiescent current to single-digit microamps for battery-backed operation. CAN or USB connectivity supports integration into building-automation backbones; the 100-LQFP package allows flexible PCB routing for HVAC actuators. Hardware cryptographic acceleration and secure boot features support anti-tamper designs.
おすすめ
White Goods Motor-Plus-Display Boards
In washing-machine, dryer and dishwasher control boards, the MK30DX128VLL7 combines SLCD user interfaces with supervisory control of BLDC or universal motors, replacing a separate display MCU plus a control MCU. The hardware FPU handles field-oriented control math; timers trigger PWM and ADC sampling synchronized to zero-crossings. Segment LCD displays cycle status, errors and timers; FlexCAN links multiple subsystems. Designers appreciate the single-chip integration reducing assembly steps and bill-of-materials.
おすすめ
Medical Segment-LCD Devices
Non-critical medical devices such as blood-pressure monitors, glucose meters and nebulizers use the MK30DX128VLL7 to drive segment-LCD readouts, run measurement algorithms on the Cortex-M4 with FPU and manage battery charging through the on-chip USB controller. The 12-bit ADC acquires sensor signals with adequate resolution for vital-sign displays, while 32 KB SRAM buffers waveform data. The 100-LQFP package fits the form factor of typical handheld medical enclosures and supports both alkaline and rechargeable battery chemistries.

主な差別化要因

- K30 sub-family shared enablement （vs MK20DX128VLL5)
設計ノート
The MK30DX128VLL7 integrates a 1.2 V core LDO driven from VDD (1.71-3.6 V). For best noise performance, place a 4.7 uF bulk + 100 nF decoupling pair within 2 mm of the VDD pins, and a separate 100 nF near each VDD pin if the package exposes multiple. Use the internal reference only when the precision is sufficient; otherwise drive VREFH from an external 2.5-3.0 V reference tied to the ADC accuracy budget.
Route the 32.768 kHz RTC crystal traces symmetrically within 5 mm of the XTAL32 pins with a ground guard on both sides and a clean ground plane reference. Keep digital switching traces away from analog ADC inputs and the VREFH/VREFL pair. Place the segment-LCD COM/SEG signals on the bottom layer when the top layer holds the glass connector, and add stitching vias around the LCD bias charge-pump area.
Do not exceed the absolute maximum VDD of 3.6 V even briefly - the internal voltage regulator does not clamp over-voltage. Configure unused pins as analog inputs with the internal pull disabled to minimize current leakage; floating inputs can draw 10-50 uA each. When entering VLLSx, ensure no DMA is active and clear it of NMI sources or wake-up behavior is undefined.
