Product details
Overview
MK40DX128ZVLQ10 from NXP is a 32-bit ARM® Cortex®-M4 microcontroller with DSP extension, operating at 100 MHz, featuring 128 KB flash, 32 KB SRAM, and 128 KB FlexMemory (EEPROM-capable), integrated Full-Speed USB 2.0 On-The-Go with device charger detect, and a low-power segment LCD controller supporting up to 320 segments - deployed in blood glucose meters and bike computers.
For engineers reviewing the MK40DX128ZVLQ10 datasheet, MK40DX128ZVLQ10 pinout, MK40DX128ZVLQ10 application, or MK40DX128ZVLQ10 equivalent, key selection criteria include USB OTG capability with DCD, LCD segment count support (40×8/44×4), 100 MHz real-time performance, FlexMemory EEPROM emulation, and LQFP-100 package compatibility for HMI-constrained portable medical and fitness devices.
Technical Context
The MK40DX128ZVLQ10 implements an ARM Cortex-M4 core with hardware floating-point unit and DSP instruction set, enabling efficient signal processing in battery-powered applications. It integrates a dedicated low-leakage wake-up unit, independent RTC, and programmable delay block for deterministic low-power timing control.
Its peripheral suite includes three FlexTimer modules (up to 12 channels total), a 16-bit ADC with PGA, dual DACs (6-bit and 12-bit), and a carrier modulator transmitter for IR remote control - all synchronized via a crossbar-switch DMA controller that supports concurrent multi-master bus access without CPU intervention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MK40DN128VLL10 | Same core, 128 KB flash, but uses LQFP-100 without LCD controller - lacks segment LCD driver and USB DCD | Suitable for non-display applications requiring CAN and higher analog integration | Select when LCD and USB charging detection are unnecessary and CAN bus connectivity is required |
| KL27Z128VLH4 | ARM Cortex-M0+, 48 MHz, 128 KB flash, 16 KB SRAM - lower performance, no USB OTG or LCD controller | Targeted at ultra-low-power sensor nodes without display or USB host capability | Choose for sub-100 µA sleep current and minimal BOM cost where display and USB features are omitted |

FAQ
What is the maximum operating frequency of the MK40DX128ZVLQ10?
The MK40DX128ZVLQ10 operates at a maximum core frequency of 100 MHz using its ARM Cortex-M4 processor with hardware FPU. This clock speed is achieved via the internal PLL locked to an external crystal or internal reference, and it sustains full peripheral functionality including USB OTG and LCD controller operation without throttling.
Does the MK40DX128ZVLQ10 support USB device charger detection?
Yes, the MK40DX128ZVLQ10 includes integrated USB Device Charger Detect (DCD) logic compliant with USB Battery Charging Specification v1.2. It automatically identifies SDP, CDP, and DCP sources and configures appropriate current limits - a feature confirmed in the K40 Family Reference Manual and used in production blood glucose meters.
How much EEPROM-equivalent memory does the MK40DX128ZVLQ10 provide?
The MK40DX128ZVLQ10 provides 32 KB of user-configurable EEPROM emulation within its 128 KB FlexMemory block. This space supports byte-level write/erase operations with built-in wear leveling - verified in the K40 Sub-Family Data Sheet Rev.9 and used for storing calibration data in medical devices.
What LCD segment configurations are supported by the MK40DX128ZVLQ10?
The MK40DX128ZVLQ10 supports up to 320 segments in configurations including 40×8 or 44×4 multiplexing. Its LCD controller allows runtime reassignment of frontplane/backplane pins and includes hardware blink mode - capabilities documented in the K40 LCD Controller chapter and applied in commercial bike computers.
Is the MK40DX128ZVLQ10 pin-compatible with other K40 family members in LQFP-100?
No, the MK40DX128ZVLQ10 is not fully pin-compatible with other K40 LQFP-100 variants such as MK40DN128VLL10 due to differences in peripheral mapping - specifically, LCD segment pins on MK40DX128ZVLQ10 replace certain GPIO and analog functions present on non-LCD derivatives.
