Product details
Overview
MKL82Z128VLK7 from NXP Semiconductors is a 72 MHz ARM® Cortex®-M0+ microcontroller with 128 KB flash, 96 KB SRAM, and hardware cryptographic acceleration, designed for ultra-low-power EMV-compliant payment terminals including smartphone-attach readers and wearable payment devices.
For engineers reviewing the MKL82Z128VLK7 datasheet, MKL82Z128VLK7 pinout, MKL82Z128VLK7 application, or MKL82Z128VLK7 equivalent, key selection criteria include its 80-pin LQFP package, EMV Level 1 software stack support, crystal-less USB OTG controller, 2.5 µA sleep mode (RTC + SRAM retained), and FlexIO-based peripheral emulation capability.
Technical Context
The MKL82Z128VLK7 implements a dual-clock domain architecture: a high-speed system clock (up to 72 MHz via FLL/PLL) for active computation and a dedicated low-leakage 32 kHz RTC domain enabling autonomous wake-up from Stop mode at 272 nA. Its security subsystem integrates a low-power trusted crypto engine supporting AES128/256, SHA256, RSA, and ECC with DPA resistance.
Peripherals operate autonomously in low-power modes: three LPUARTs, two I²C modules (up to 1 Mbps), two SPIs (up to 24 Mbps), and FlexIO (32-channel serial emulation) retain functionality without CPU intervention. The 16-bit ADC (16-channel SE/DP) and dual EMVSIM modules are explicitly validated for ISO/IEC 7816-3 SIM interface compliance.

FAQ
What is the maximum operating frequency of the MKL82Z128VLK7 core?
The MKL82Z128VLK7 features an ARM Cortex-M0+ core rated for up to 72 MHz under standard conditions, with optional high-speed run mode supporting up to 96 MHz using the on-chip PLL or FLL. This frequency is confirmed in the official KL82P121M72SF0 datasheet Rev. 4, Section 2.1.1, and applies specifically to the MKL82Z128VLK7 part number in its 80-pin LQFP package.
Does the MKL82Z128VLK7 support EMV Level 1 certification out of the box?
Yes-the MKL82Z128VLK7 includes dual EMVSIM modules compliant with ISO/IEC 7816-3 and ships with an NXP-provided EMV Level 1 software stack. Its hardware-level EMV interface support, combined with the low-power trusted crypto engine, enables direct integration into PCI PTS v6.0-certified payment terminals without external interface ICs.
What is the lowest power consumption mode supported by the MKL82Z128VLK7 with SRAM and RTC retained?
The MKL82Z128VLK7 achieves 272 nA in Stop mode with both SRAM content and RTC retained, as specified in the KL82P121M72SF0 datasheet Section 5.4.1. This mode disables the CPU and most peripherals while preserving critical state-enabling multi-week battery life in intermittent-use payment devices.
Can the MKL82Z128VLK7 operate USB without an external crystal?
Yes-the MKL82Z128VLK7 integrates a crystal-less USB full-speed OTG controller using an internal 48 MHz IRC oscillator synchronized to USB timing requirements. This eliminates the need for an external 48 MHz crystal, reducing BOM cost and PCB area, and is explicitly validated for MKL82Z128VLK7 in the datasheet Section 2.2.14.
How many general-purpose I/O pins does the MKL82Z128VLK7 provide in its 80-pin LQFP package?
The MKL82Z128VLK7 in the 80-pin LQFP package provides 56 general-purpose I/O pins, as documented in Table 1 (Ordering Information) of the KL82P121M72SF0 datasheet Rev. 4. These are distributed across GPIO ports A–E and include dedicated functions for EMVSIM, USB, QSPI, and FlexIO-leaving 24 pins for user-defined use.
