NXP Semiconductors MKL82Z128VMP7

Overview

MKL82Z128VMP7 from NXP Semiconductors is a 72 MHz ARM® Cortex®-M0+ microcontroller with 128 KB flash, 96 KB SRAM, and hardware cryptographic acceleration for EMV®-compliant payment terminals. It integrates USB full-speed OTG (crystal-less), dual EMVSIM interfaces, 16-bit ADC (11-channel SE/1-channel DP), and FlexIO for peripheral emulation - deployed in smartphone-attach card readers and wearable payment devices.

For engineers reviewing the MKL82Z128VMP7 datasheet, MKL82Z128VMP7 pinout, MKL82Z128VMP7 application, or MKL82Z128VMP7 equivalent, key selection criteria include its 64-pin MAPBGA (5×5 mm, 0.5 mm pitch), -40 to 105°C industrial temperature range, 2.5 µA sleep mode (RTC + SRAM retained), and EMV Level 1 software stack support.

Technical Context

The MKL82Z128VMP7 implements a dual-clock domain architecture: 48 MHz IRC48M for USB timing accuracy and 4 MHz IRC for ultra-low-power run modes. Its low-power operation relies on PMC-controlled six static power modes, including Stop mode at 272 nA with RTC and SRAM retention.

Security is enforced via hardware TRNG, AES128/256, SHA256, RSA, ECC, and DPA-resistant crypto engine, coupled with flash memory protection unit and 128-bit unique chip ID. Peripheral autonomy in low-power states is enabled by LPUART, FlexIO, and ADC operating independently of CPU intervention.

FAQ

What is the package type and pin count of the MKL82Z128VMP7?

The MKL82Z128VMP7 uses a 64-pin MAPBGA package measuring 5 mm × 5 mm with 0.5 mm pitch and maximum height of 1.23 mm. This compact footprint is validated in NXP package drawing 98ASA00420D and supports high-density layouts required for portable payment devices. The MKL82Z128VMP7 exposes 41 GPIOs and dedicated EMVSIM/USB pins within this configuration.

Does the MKL82Z128VMP7 support EMV Level 1 certification out of the box?

Yes, the MKL82Z128VMP7 includes dual EMVSIM modules compliant with ISO/IEC 7816-3 and is supported by an NXP-provided EMV Level 1 software stack. The hardware timing accuracy, built-in CRC, and secure crypto engine enable direct integration into certified payment terminals without external timing or security ICs - though final certification requires third-party lab validation of the full system.

Can the MKL82Z128VMP7 operate USB without an external crystal?

Yes, the MKL82Z128VMP7 features a crystal-less USB full-speed OTG controller that uses its internal 48 MHz IRC oscillator, synchronized to meet USB timing specifications. This eliminates the need for an external 48 MHz crystal and associated load capacitors, reducing BOM cost and PCB area - a key advantage for space-constrained MKL82Z128VMP7 designs like attachable card readers.

What low-power modes are supported by the MKL82Z128VMP7, and what is the lowest current draw?

The MKL82Z128VMP7 supports six flexible low-power modes, including Stop mode at 272 nA with RTC and SRAM retained, and Run mode down to 125 µA/MHz. Its PMC controller enables precise trade-offs between wake latency and current consumption - critical for MKL82Z128VMP7 applications such as battery-powered wearables that must maintain state across weeks of inactivity.

Is there hardware cryptographic acceleration in the MKL82Z128VMP7, and which algorithms does it support?

Yes, the MKL82Z128VMP7 integrates a low-power trusted crypto engine supporting AES128/256, DES, 3DES, SHA256, RSA, and ECC - all with hardware DPA resistance. This offloads computationally intensive operations from the Cortex-M0+ core, reducing active time and power while meeting PCI PTS v6.0 requirements for secure transaction processing in the MKL82Z128VMP7.
