Application Field

The MKL34Z64VLL4 is a highly integrated and robust microcontroller suited for a wide array of embedded applications. MKL34Z is a member of the Kinetis L family that, combined with its 32-bit ARM Cortex-M0+ core and various peripheral features, offers high-end performance without sacrificing power consumption. Its 32-bit processor runs slower clocks than the Cortex-M3, which saves power consumption relative to slightly faster systems. Furthermore, it is suitable for deployment in wearable electronic applications, security systems, and low-cost consumer electronics such as toys and appliances. Also, its low speed means that it can be powered by just one 1.8V power source, which is great for low power solutions.

Working Principle

The MKL34Z64VLL4 microcontroller has a versatile architecture which includes a wide range of functions and peripherals. The ARM Cortex-M0+ core is responsible for instruction fetching and execution, interrupt handling, data prefetching, and the State Configurable Timer (SCT). Additionally, the MKL34Z has a 32-bit timer, fast analogue comparator, variable and complex asynchronous communication, multiple versions of digital/analogue peripherals, and a touch sensing unit. At the heart of the controller, the ARM Cortex-M0+ core provides low-latency, low-power processing with an asynchronous 5-stage pipeline, frequency up to 48 MHz, 1.25 DMIPS/MHz, and 16-bit instructions. In addition, it supports up to 2KB of instruction cache and 512-byte data cache to increase code efficiency and reduce the usage of RAM. The controller also has 4KB each of RAM and EEPROM memory, 16KB of Program Flash, and 16 GPIO pins.

The touch sensing feature of the MKL34Z64VLL4 is especially useful for low-power wearable electronics, medical instruments, and home appliances. It utilizes the Electrostatic Field Sensor (EFS) technology which overcomes the disadvantages of traditional solutions by providing accurate touch sensing, low power operation and a high integration level. It can also detect touches from up to 8 touch points simultaneously and can be used as a substitute for physical buttons. With its low power operation, the MKL34Z64VLL4 makes an efficient solution for wearable devices and home automation solutions.

The MKL34Z64VLL4 can also be used for applications such as communication, industrial automation, and transport automation. In communication applications, the microcontroller is compatible with multiple standards including 802.15.4, ZigBee®, 6LoWPAN, and IPv6. It also provides robust security features via the ARM TrustZone security extension. In industrial automation, the controller features motor control, multi-mode quadrature encoder interfaces (QEI), analog-to-digital converters (ADCs) with 12-bit resolution, I2C, SPI and CAN bus for signal and data transfer. In addition, it has two standard CAN transceivers for compatibility with CAN networks.

The MKL34Z64VLL4 microcontroller makes an ideal embedded solution for a wide range of embedded applications. Drag-and-drop programming, using NXP’s drag-n-drop programming tool, greatly simplifies programming and debugging. Its high integration, low power operation, accuracy, and robust security features make it an ideal choice for a variety of applications.
