Product details
Overview
MKL34Z64VLH4 from NXP Semiconductors (formerly Freescale) is a 48 MHz ARM Cortex-M0+ microcontroller with 64 KB flash, 8 KB SRAM, segment LCD controller, and ultra-low-power operation down to 0.23 µA in VLLS0 mode. It integrates dual UARTs, two I²C, two SPI, 12-bit ADC, analog comparator with 6-bit DAC, six-channel TPM, real-time clock, and SWD debug interface - designed for battery-powered human-machine interface applications including smart meters and portable medical devices.
For engineers reviewing the MKL34Z64VLH4 datasheet, MKL34Z64VLH4 pinout, MKL34Z64VLH4 application, or MKL34Z64VLH4 equivalent, key selection considerations include its 64-pin LQFP package, 1.71–3.6 V operating voltage, -40°C to +105°C temperature range, segment LCD support up to 47×8, and verified low-power run mode current of 192 µA at 4 MHz.
Technical Context
The MKL34Z64VLH4 implements an ARM Cortex-M0+ core with Bit Manipulation Engine and Micro Trace Buffer, paired with a multi-mode clock system featuring MCG supporting FEI, FBE, BLPI, and VLPR configurations. Its power architecture includes nine low-power modes - from VLPR (Very-Low-Power Run) to VLLS0 (Very-Low-Leakage Stop Mode 0) - with sub-µA retention and 4.5 µs wakeup from VLPS.
Peripheral integration centers on mixed-signal capability: a 12-bit SAR ADC with configurable sample time and hardware averaging, CMP with programmable reference and integrated 6-bit DAC, and a dedicated segment LCD controller supporting 384 segments via 47 frontplanes/8 backplanes or 204 segments via 51 frontplanes/4 backplanes - all optimized for direct glass drive without external bias circuitry.
