1 TWR-K40X256 and TWR-K40X256-KIT Overview
The TWR-K40X256 is a Tower Controller Module compatible with the Freescale Tower System. It can
function as a stand-alone, low-cost platform for the evaluation of the Kinetis K30 and K40 family of
microcontroller (MCU) devices. The TWRPI-SLCD segment LCD daughter card is included as part of the
TWR-K40X256.
The TWR-K40X256 features the Kinetis K40 low-power microcontroller based on the ARM® Cortex™-
M4 architecture with USB 2.0 full-speed OTG and segment LCD display controllers. The K40X256
includes 256Kbytes of program flash storage and an additional 256Kbytes of FlexMemory non-volatile
storage that can be used as additional program flash memory, data flash, or variable size/endurance
EEPROM.
The TWR-K40X256 is available as a stand-alone product or as a kit (TWR-K40X256-KIT) with the Tower
Elevator Modules (TWR-ELEV) and the Tower Serial Module (TWR-SER). The TWR-K40X256 can also be
combined with other Freescale Tower peripheral modules to create development platforms for a wide
variety of applications. Figure 1 provides an overview of the Freescale Tower System.
