NXP Semiconductors MKL82Z128VMC7

Overview

MKL82Z128VMC7 from NXP Semiconductors is a 72 MHz ARM® Cortex®-M0+ microcontroller with 128 KB flash, 96 KB SRAM, hardware asymmetric cryptography, EMV®-compatible ISO7816-3 SIM interfaces, and crystal-less USB OTG-designed for ultra-low-power payment terminals, smartphone-attach readers, and wearable payment devices.

For engineers reviewing the MKL82Z128VMC7 datasheet, MKL82Z128VMC7 pinout, MKL82Z128VMC7 application, or MKL82Z128VMC7 equivalent, key selection criteria include EMV Level 1 software stack support, 2.5 µA sleep mode with RTC + SRAM retention, FlexIO-based peripheral emulation, QSPI expandable code memory, and 85 GPIOs in 121-pin MAPBGA.

Technical Context

The MKL82Z128VMC7 integrates a 72 MHz (up to 96 MHz high-speed run) ARM Cortex-M0+ core with an enhanced NVIC supporting 32 interrupt vectors and 4 priority levels, plus AWIC and LLWU controllers enabling wake-up from Stop, VLPS, and VLLS modes via LPUART, FlexIO, RTC, or EMVSIM peripherals.

Its clock system combines 48 MHz IRC (USB-locked), 4 MHz IRC (VLPR), 32 kHz IRC, 1 kHz LPO, and configurable FLL/PLL with external crystal support (3–32 MHz), allowing dynamic trade-offs between timing accuracy, power, and peripheral availability across six static low-power modes.

FAQ

What is the maximum operating frequency of the MKL82Z128VMC7?

The MKL82Z128VMC7 features an ARM Cortex-M0+ core with a maximum operating frequency of 72 MHz under standard run conditions, and supports up to 96 MHz in high-speed run mode. This frequency is achievable using the on-chip PLL or FLL with appropriate clock source configuration, and is validated across the full –40°C to +105°C temperature range specified for the MKL82Z128VMC7.

Does the MKL82Z128VMC7 support EMV Level 1 certification out of the box?

Yes, the MKL82Z128VMC7 includes dual EMVSIM modules compliant with ISO7816-3 and ships with an NXP-provided EMV Level 1 software stack. The hardware crypto engine and secure boot ROM enable full EMV L1 qualification without external secure elements-making MKL82Z128VMC7 a purpose-built solution for certified payment devices.

What package options are available for the MKL82Z128VMC7?

The MKL82Z128VMC7 is specifically offered in the 121-pin MAPBGA package (8 mm × 8 mm, 0.65 mm pitch). While other variants in the KL82 family use 64- or 100-pin LQFP/MAPBGA packages, only the MKL82Z128VMC7 part number corresponds to the 121-pin MAPBGA configuration per NXP's official ordering information.

Can the MKL82Z128VMC7 operate USB without an external crystal?

Yes, the MKL82Z128VMC7 integrates a crystal-less USB full-speed OTG controller. It uses an internal 48 MHz IRC oscillator synchronized to USB frame timing, eliminating the need for an external 12 MHz crystal and associated passive components-confirmed in the KL82P121M72SF0 datasheet section 2.2.14 for the MKL82Z128VMC7.

How many GPIOs does the MKL82Z128VMC7 provide in its 121-pin MAPBGA package?

The MKL82Z128VMC7 in the 121-pin MAPBGA package provides up to 85 general-purpose I/O pins, as documented in Table 1 of the KL82P121M72SF0 datasheet. These GPIOs support multiple functions including interrupt, high-drive, and analog input capabilities, with full multiplexing control via the IOPORT module.
