Product details
Overview
MK40DX256ZVMB10 from NXP is a 32-bit ARM® Cortex®-M4 microcontroller operating at 100 MHz, featuring 256 KB flash, 64 KB SRAM, and 256 KB FlexMemory (EEPROM-emulated), with Full-Speed USB 2.0 On-The-Go and a segment LCD controller supporting up to 320 segments - deployed in portable medical devices like blood glucose meters and bike computers.
For engineers reviewing the MK40DX256ZVMB10 datasheet, MK40DX256ZVMB10 pinout, MK40DX256ZVMB10 application, or MK40DX256ZVMB10 equivalent, key selection considerations include USB OTG device charger detect capability, low-power LCD segment drive (40×8 or 44×4), FlexMemory byte-write EEPROM functionality, and 100 MHz real-time performance with DSP instruction support.
Technical Context
The MK40DX256ZVMB10 implements an ARM Cortex-M4 core with hardware floating-point unit and DSP extensions, enabling efficient signal processing in battery-powered HMI applications. It integrates a dedicated low-leakage wake-up unit, independent RTC, and programmable delay block for deterministic low-power operation.
Its peripheral set includes three FlexTimer modules (up to 12 channels total), carrier modulator transmitter for IR remote control, and a 16-bit ADC with PGA - all synchronized via a crossbar-switch DMA controller that supports concurrent multi-master bus access without CPU intervention.

FAQ
What is the package type and pin count of the MK40DX256ZVMB10?
The MK40DX256ZVMB10 uses a 144-pin MAPBGA package (13 mm × 13 mm, 0.8 mm pitch) with exposed thermal pad. This fine-pitch ball grid array supports high-density routing and superior thermal dissipation for sustained 100 MHz operation in portable devices - a key differentiator from the LQFP variants of the same K40 family.
Does the MK40DX256ZVMB10 support USB Battery Charging (BC) 1.2 specification?
Yes, the MK40DX256ZVMB10 includes hardware-based USB Device Charger Detect (DCD) logic compliant with USB BC 1.2. This enables automatic identification of standard downstream ports, charging downstream ports, and dedicated chargers - allowing MK40DX256ZVMB10-based devices to negotiate optimal charging current without host enumeration delays.
How does FlexMemory work in the MK40DX256ZVMB10, and what is its effective EEPROM capacity?
The MK40DX256ZVMB10 allocates 256 KB of FlexMemory for EEPROM emulation, configurable in segments from 32 bytes to 4 KB. Each segment supports byte-write and sector-erase operations with built-in wear leveling - delivering up to 100,000 write/erase cycles per segment, eliminating need for external EEPROM in applications like calibration storage and usage logging.
Can the MK40DX256ZVMB10 drive a 40×8 segment LCD without external components?
Yes, the MK40DX256ZVMB10's integrated segment LCD controller directly drives up to 320 segments (e.g., 40×8 or 44×4) with internal bias generation and voltage regulation. No external LCD bias IC, charge pump, or resistor networks are required - reducing BOM cost and board area while maintaining compatibility with both 3 V and 5 V LCD panels.
What debug interfaces are supported by the MK40DX256ZVMB10?
The MK40DX256ZVMB10 supports SWD (Serial Wire Debug) and JTAG interfaces via dedicated debug pins. It is fully compatible with ARM Keil MDK, IAR Embedded Workbench, and NXP's CodeWarrior IDE - enabling real-time debugging, flash programming, and boundary-scan testing without requiring additional debug probes beyond standard CMSIS-DAP adapters.
