NXP Semiconductors MKL33Z128VMP4

Overview

MKL33Z128VMP4 from NXP Semiconductors (formerly Freescale) is a 48 MHz ARM® Cortex®-M0+ microcontroller with 128 KB flash, 16 KB SRAM, and integrated segment LCD controller supporting up to 28×8 segments. It delivers 54 µA/MHz in very low power run mode and 1.96 µA in VLLS3 deep-sleep mode (RAM + RTC retained), targeting battery-powered metering and portable HMI devices.

For engineers reviewing the MKL33Z128VMP4 datasheet, MKL33Z128VMP4 pinout, MKL33Z128VMP4 application, or MKL33Z128VMP4 equivalent, key selection criteria include its 64-pin MAPBGA package (5×5 mm, 0.5 mm pitch), 54 GPIOs (including 6 high-drive), 20-channel 16-bit ADC with internal Vref, FlexIO for peripheral emulation, and support for ISO7816 UART - all operating across –40 to 105 °C at 1.71–3.6 V.

Technical Context

The MKL33Z128VMP4 implements an ARM Cortex-M0+ core with Micro Trace Buffer and Bit Manipulation Engine, paired with a configurable MCG-Lite clock system offering 48 MHz HIRC (±0.5%), 8/2 MHz IRC (±3%), and 32 kHz–32 MHz crystal support. Its low-power architecture includes six static power modes, LLS/VLLS entry/exit times under 104 µs, and dedicated low-leakage wakeup unit.

Peripherals are optimized for cost-sensitive HMI: a hardware segment LCD controller (28×8 or 32×4), two low-power UARTs active in VLPS/LLS, FlexIO enabling runtime emulation of IrDA/SPI/I²C/I²S/PWM, and analog subsystem comprising 16-bit 818 ksps ADC, 12-bit DAC, high-speed comparator with 6-bit DAC reference, and 1.2 V internal voltage reference.

FAQ

What is the maximum operating frequency and core type of the MKL33Z128VMP4?

The MKL33Z128VMP4 features an ARM Cortex-M0+ core rated for up to 48 MHz operation. This core delivers efficient real-time performance with low gate count and energy-per-instruction advantage over Cortex-M3/M4. The device achieves this speed using its high-accuracy internal 48 MHz HIRC oscillator (±0.5% tolerance), eliminating need for external crystal in many applications. MKL33Z128VMP4 supports both HIRC and external crystal sources with automatic failover.

Does the MKL33Z128VMP4 support segment LCD displays, and what are the configuration limits?

Yes, the MKL33Z128VMP4 includes a dedicated hardware segment LCD controller supporting up to 28×8 or 32×4 segments. It drives common-electrode LCD glass directly without external driver ICs, reducing BOM cost and PCB space. Configuration is software-controlled via LCD registers, with support for static, 2-, 3-, or 4-mux modes. MKL33Z128VMP4 requires external bias resistors or capacitors per display type, and operates across full temperature range (–40 to 105 °C).

What low-power modes does the MKL33Z128VMP4 offer, and what is the lowest achievable current draw?

The MKL33Z128VMP4 offers six flexible low-power modes: RUN, VLPR, WAIT, STOP, LLS, and VLLS (0/1/3). The lowest current is 1.96 µA in VLLS3 mode with RAM and RTC retained at 3.0 V and 25 °C. In VLLS1 mode, current drops to 0.66 µA (typ) with RTC enabled. All modes maintain GPIO state and allow wake-up via multiple sources including LPTMR, RTC alarm, or external pins. MKL33Z128VMP4 achieves these values without external components.

How many ADC channels and what resolution does the MKL33Z128VMP4 provide?

The MKL33Z128VMP4 integrates a 16-bit successive-approximation ADC with up to 20 input channels (16 single-ended or 4 differential). It samples at up to 818 ksps and includes a high-accuracy internal voltage reference (1.2 V ±1.5%) for stable conversions independent of supply voltage. The ADC supports hardware averaging, continuous conversion, and trigger sources including timers and FlexIO. MKL33Z128VMP4 also provides programmable gain and offset calibration registers.

Is the MKL33Z128VMP4 pin-compatible with other Kinetis KL33 variants, and what package options exist?

The MKL33Z128VMP4 uses a 64-pin MAPBGA (5×5 mm, 0.5 mm pitch) and is not pin-compatible with the 64-LQFP variant MKL33Z128VLH4 due to differing pin assignments and thermal pad configuration. Both share identical peripheral sets and memory map, but require separate PCB layouts. MKL33Z128VMP4 is functionally identical to MKL33Z256VMP4 except for flash size (128 KB vs. 256 KB) and SRAM (16 KB vs. 32 KB); no other electrical or timing differences exist.
