NXP Semiconductors MK10DX128VMB7

Overview

MK10DX128VMB7 from NXP Semiconductors (formerly Freescale) is a Kinetis K10-series ARM Cortex-M4 microcontroller with DSP extension, designed for embedded control applications requiring mixed-signal integration and low-power operation. It features 128 KB flash, 16 KB SRAM, operates from 1.71–3.6 V, supports –40 to 105°C ambient temperature, and delivers up to 72 MHz core performance. It is used in industrial sensor nodes and motor control interfaces where analog acquisition, real-time timing, and CAN communication are critical.

For engineers reviewing the MK10DX128VMB7 datasheet, MK10DX128VMB7 pinout, MK10DX128VMB7 application, or MK10DX128VMB7 equivalent, key selection considerations include its dual 16-bit SAR ADCs with integrated PGA, 12-bit DAC, CAN 2.0B interface, eight-channel PWM timer, and support for 10 low-power modes - all in an 81-pin MAPBGA package.

Technical Context

The MK10DX128VMB7 implements a 32-bit ARM Cortex-M4 core with DSP instructions and no FPU. Its clock system includes a 3–32 MHz main crystal oscillator, 32 kHz RTC oscillator, and multi-purpose clock generator supporting multiple PLL configurations. Memory subsystem comprises 128 KB on-chip flash with error correction, 16 KB SRAM, and FlexMemory support enabled via the 'X' flash type flag.

Peripheral integration includes two SPI, two I²C, four UART, one I²S, and one Controller Area Network (CAN) module compliant with ISO 11898-1. Analog subsystem contains two independent 16-bit SAR ADCs (each with programmable gain amplifier up to ×64), a 12-bit DAC, three analog comparators (each with 6-bit DAC and programmable reference), and a hardware CRC module for data integrity verification.

FAQ

What is the maximum operating frequency of the MK10DX128VMB7?

The MK10DX128VMB7 supports a maximum core clock frequency of 72 MHz, achieved using the internal PLL 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 voltage. The MK10DX128VMB7 achieves this speed while maintaining full peripheral functionality including dual ADCs, CAN, and DMA - making it suitable for deterministic real-time control applications.

Does the MK10DX128VMB7 include a hardware floating-point unit (FPU)?

No, the MK10DX128VMB7 implements the ARM Cortex-M4 core with DSP extensions but does not include a hardware floating-point unit (FPU). Its 'D' designation in the part number (MK10D…) confirms DSP instruction support only. Applications requiring intensive floating-point math must use software libraries or consider F-series variants like MK10DF128VMB7, which explicitly include the FPU. The MK10DX128VMB7 remains optimal for fixed-point control, filtering, and sensor processing where DSP acceleration suffices.

What analog peripherals are integrated into the MK10DX128VMB7?

The MK10DX128VMB7 integrates two independent 16-bit SAR ADCs, each with a programmable gain amplifier (PGA) supporting gains from ×1 to ×64; a 12-bit DAC; three analog comparators (each with a built-in 6-bit DAC and programmable reference input); and a precision voltage reference module. These resources enable high-fidelity sensor signal acquisition, closed-loop analog output control, and comparator-based event triggering - all without external signal conditioning components. This analog integration is fully supported in the MK10DX128VMB7 silicon revision.

Is the MK10DX128VMB7 pin-compatible with other K10 family members?

The MK10DX128VMB7 uses the 81-pin MAPBGA (MB) package and shares pin assignments with other K10 devices in the same package variant, such as MK10DX64VMB7 and MK10DX256VMB7. However, pin compatibility does not guarantee full functional or register-level compatibility - differences in flash size, RAM, and peripheral enablement require firmware validation. The MK10DX128VMB7 pinout is defined in K10P81M72SF1 Rev. 2, Section 8.2, and must be verified against target PCB layout before substitution.

What low-power modes does the MK10DX128VMB7 support, and what is the lowest achievable current draw?

The MK10DX128VMB7 supports 10 distinct low-power modes, including VLLS1, VLLS2, and VLLS3. In VLLS3 mode with RTC running from VBAT and minimal wakeup sources enabled, the MK10DX128VMB7 draws as little as 1.9 μA at –40 to 25°C (typical) and 28.1 μA at 105°C. This ultra-low leakage is achieved via selective clock gating, retention of critical registers, and optimized SRAM power domains - enabling multi-year operation from coin-cell batteries in always-on monitoring applications.
