1 Overview
The Tower LCD Module (TWR‐LCD) adds a side mounting TFT QVGA Display to the Freescale Tower
System. It can be used with a wide variety of Tower Processor Modules through a SPI and/or external
bus interface (EBI).
The TWR‐LCD features a 3.2” QVGA TFT LCD Display with touch sensitive overlay, 5‐way navigation
control, MicroSD Card slot, dedicated MCF51JM microcontroller, and a Piezo Buzzer for audible
feedback. The LCD Display Controller is accessible to the dedicated MCF51JM microcontroller through
the SPI. The LCD Display Controller is also accessible to any capable Tower MCU module utilizing either
the SPI or the EBI. A block diagram for the TWR‐LCD is shown in the figure below.
