NXP Semiconductors MKL46Z256VMP4

Overview

MKL46Z256VMP4 from NXP Semiconductors (formerly Freescale) is a 48 MHz ARM Cortex-M0+ microcontroller in 64-pin MAPBGA package, featuring 256 KB flash, 32 KB SRAM, USB 2.0 On-The-Go with on-chip transceiver, segment LCD controller (up to 47×8), and ultra-low-power operation down to 0.23 µA in VLLS0 mode. It targets battery-powered HMI, portable medical devices, and industrial sensor nodes requiring robust low-power performance and integrated analog peripherals.

For engineers reviewing the MKL46Z256VMP4 datasheet, MKL46Z256VMP4 pinout, MKL46Z256VMP4 application, or MKL46Z256VMP4 equivalent, key selection criteria include its 4 MHz VLPR mode operation, 16-bit SAR ADC with 366 µA adder in STOP mode, 12-bit DAC, dual UART + I²C + SPI interfaces, and verified 64-pin 5×5 mm MAPBGA (pitch 0.5 mm) mechanical compatibility.

Technical Context

The MKL46Z256VMP4 implements a single-core ARM Cortex-M0+ processor with Bit Manipulation Engine and Micro Trace Buffer for debug visibility. Its clock system integrates MCG with FEI/FBE/BLPI/BLPE modes, supporting crystal oscillators from 32 kHz to 32 MHz and internal reference clocks at 4 MHz or 32 kHz.

Power management includes nine low-power modes-VLPR, VLPS, LLS, STOP, and four VLLS variants-with independent clock gating, dynamic voltage scaling, and full state retention at ≤2 µA. The USB module operates in full/low-speed OTG mode with integrated 5 V-to-3.3 V regulator and on-chip transceiver compliant with USB 2.0 specification.

FAQ

What is the maximum operating frequency of the MKL46Z256VMP4 core?

The MKL46Z256VMP4 features an ARM Cortex-M0+ core rated for up to 48 MHz operation in normal run mode. This frequency is supported across the full 1.71–3.6 V supply range and –40°C to +105°C ambient temperature. In very-low-power run (VLPR) mode, the core operates up to 4 MHz to minimize active current while retaining full SRAM and register state.

Does the MKL46Z256VMP4 include a USB transceiver?

Yes, the MKL46Z256VMP4 integrates a full-/low-speed USB 2.0 On-The-Go controller with an on-chip transceiver and a 5 V-to-3.3 V regulator. This eliminates the need for external PHY components and simplifies board design for USB device or host functionality, as confirmed in the KL46P121M48SF4 datasheet Section 3.8.1.

What package type and dimensions does the MKL46Z256VMP4 use?

The MKL46Z256VMP4 is packaged in a 64-pin MAPBGA (MP) with 5 mm × 5 mm body size, 1.23 mm height, and 0.5 mm ball pitch. Its mechanical outline matches JEDEC MO-277, and package drawing 98ASA00420D1 confirms land pattern and solder mask requirements for reliable assembly.

Can the MKL46Z256VMP4 drive a segment LCD display directly?

Yes, the MKL46Z256VMP4 includes a dedicated segment LCD controller supporting up to 47 frontplanes and 8 backplanes (376 segments) or 51 frontplanes and 4 backplanes (204 segments). It provides internal charge pump, resistor bias network, and frame rate control - enabling direct drive of common LCD glass without external driver ICs.

What is the lowest power consumption mode available on the MKL46Z256VMP4?

The MKL46Z256VMP4 achieves its lowest active current in Very Low-Leakage Stop Mode 0 (VLLS0), with typical current draw of 0.23 µA at 3.0 V and 25°C when PORPO = 1. In this mode, the device retains full SRAM and register contents, supports RTC operation, and wakes in ≤124 µs - making it ideal for multi-year battery applications.
