概述

Description

MKW21D512VHA5 is an NXP Freescale Kinetis KW21D family wireless microcontroller. It combines a 32-bit ARM Cortex‑M0+ MCU with an on‑chip 2.4 GHz IEEE 802.15.4/ZigBee/Thread radio, aimed at low‑power IoT and wireless sensor applications. It includes 512 KB of flash memory (and accompanying RAM), multiple GPIOs, timers, ADC/DAC, and common serial peripherals (UART/SPI/I2C), plus various power‑save modes for battery operation. The VHA5 suffix denotes the specific package/temperature variant.

Features

Key features of MKW21D512VHA5 (Kinetis Wireless MCU):
- CPU: ARM Cortex‑M0+ core, up to 48 MHz
- Memory: 512 KB flash, ~128 KB RAM (on‑chip)
- Wireless: integrated 2.4 GHz IEEE 802.15.4 transceiver (ZigBee/Thread/6LoWPAN)
- Security: hardware cryptography (AES/DES, SHA) and RNG
- Peripherals: serial interfaces (UART, I2C, SPI), multiple timers, PWM
- Analog: ADC (and/or DAC as supported by variant)
- Power: low‑power modes with fast wakeup; operates from ~1.8–3.6 V
- Debug/Programming: SWD/JTAG debug support
- Package: VHA5 variant (specific QFN/BGA footprint)
Note: exact RAM size, analog features, and I/O counts vary by package/revision; consult the datasheet for precise specifications.

Package

The MKW21D512VHA5 is supplied in a 48‑pin QFN (LGA-style) package, typically a 6 x 6 mm body.

Pinout
