It is rated from -40°C to 105°C and operates from a 1.71 V to 3.6 V supply. The 80-LQFP package exposes 70 I/O lines, plus a 16-channel 16-bit ADC and a single 12-bit DAC. ## 48 MHz Cortex-M0+ — what the clock buys you At 48 MHz, this core handles deterministic control loops, Modbus polling, and basic signal processing without a cache or FPU. The Cortex-M0+ is a single-cycle I/O and interrupt-response architecture. 128 KB of Flash is the mid-density option in the KL1x family — enough for a full bootloader, a Modbus or CANopen stack, and a moderate application layer. The 16 KB RAM supports a handful of large buffers or a small RTOS heap. ## Industrial temperature range — deployment context The 105°C upper limit covers self-heating inside a sealed enclosure; the -40°C floor handles cold-start in northern-climate installations. The 1.71 V minimum supply ensures the MCU stays operational as a battery pack nears end-of-discharge. ## On-chip peripherals and connectivity The 16-channel 16-bit ADC samples at sufficient rate for multi-sensor acquisition; the single 12-bit DAC handles one analog output channel. Brown-out detect, low-voltage detect, power-on reset, and a watchdog timer are integrated — no external supervisor needed for basic safety monitoring.","metaTitle":"NXP MKL15Z128VLK4R Kinetis KL1 MCU, 48MHz Cortex-M0+, 128KB Flash","metaDescription":"NXP MKL15Z128VLK4R 32-bit ARM Cortex-M0+ MCU at 48MHz, 128KB Flash, 16KB RAM, 70 I/O, -40°C to 105°C, 80-LQFP.
