This manual introduces the TWR‑K40X256 Tower Module, a stand‑alone or kit‑based development platform for Kinetis K30/K40 microcontrollers. It describes the module’s features, including the MK40X256VMD100 MCU, segment LCD plug‑in, accelerometer, LEDs, touch pads, and expansion connectors.
The document details hardware sections such as clocking, system power, debug interfaces (OSJTAG and Cortex Debug+ETM), connector pin‑outs, jumper settings, and tower‑elevator connections, along with reference documents and getting‑started guidance.
| Microcontroller | MK40X256VMD100 (ARM Cortex‑M4) |
|---|---|
| Core Frequency | 100 MHz maximum |
| Program Flash | 256 KB |
| Operating Voltage | 1.71 V – 3.6 V |
| Package | 144‑lead MAPBGA, 13 mm × 13 mm |
It uses the MK40X256VMD100, a 32‑bit ARM Cortex‑M4 core device.
Power is supplied from a 5.0 V source via the USB mini‑B connector, a low‑dropout regulator then provides 3.3 V to the MCU.
The module provides an on‑board OSJTAG circuit and an external Cortex Debug+ETM connector for debugging.
The Primary and Secondary Elevator connectors on the module provide the interface to Tower elevator boards.
