Hardware description

6 Hardware description

The TWR-KL43Z is a T ower MCU Module featuring the MKL43Z256VLH4 — a Kinetis microcontroller
with USB 2.0 full-speed device controllers in a 64-LQFP package. It is intended for use in the Freescale
T ower System but can operate standalone. An on-board OpenSDA debug circuit provides a SWD interface
and a power supply input through a single USB mini-AB connector.

The block diagram of the TWR-KL43Z board is presented in Figure 3.

6.2 Microcontroller

The TWR-KL43Z is a T ower MCU module featuring the MKL43Z256VLH4 —a Kinetis microcontroller
with USB 2.0 full-speed device controller and segment LCD controller in a 64 LQFP package. It is
intended for use in the Freescale Tower System but can operate standalone. An on-board debug circuit,
OpenSDA, provides a SWD interface and a power supply input through a single USB mini-AB connector ,
as well as serial to USB and CDC class compliant UART interface.

Table 1. Features of MKL43Z256VLH4

Feature Description

Ultra-low-power - 10 low-power modes with power and clock gating for optimal peripheral activity and

recovery times. Stop current s of <190 nA (VLLS0), run currents of <280 uA/MHz, 4 s wake-up
from Stop mode

- Full memory and analog operation down to 1.71V for extended battery life

- Low-leakage wake-up unit with up to eight internal modules and eight pins as wake-up
sources in low-leakage stop (LLS)/very low-leakage stop (VLLS) modes

- Low-power timer for continual system operation in reduced power states
