MKL34Z64VLL4

The Kinetis KL34 sub-family is a Cortex-M0+ based microcontroller running at 48 MHz, designed for high efficiency and compatible with all other Kinetis L family and Kinetis K3x family devices. It is a general-purpose microcontroller featuring a segment LCD and ultra-low power consumption, providing developers with an ideal entry-level 32-bit solution. The sub-family offers two package options: a 64-pin LQFP (LH) package measuring 10×10×1.4 mm with 0.5 mm pin pitch, and a 100-pin LQFP (LL) package measuring 14×14×1.4 mm with 0.5 mm pin pitch, including part numbers MKL34Z64VLH4 and MKL34Z64VLL4.
