TSC2300
SLAS372 — NOVEMBER 2002
OVERVIEW
The TSC2300 is an analog interface circuit for human interface devices. A register-based architecture eases
integration with microprocessor-based systems through a standard SPI bus. All peripheral functions are
controlled through the registers and onboard state machines.
The TSC2300 consists of the following blocks (refer to the block diagram on p. 2):
Touch Screen Interface
Keypad Interface
Battery Monitors
Auxiliary Inputs
Temperature Monitor
Current Output Digital-to-Analog Converter
Audio Codec and Signal Processing
Communication to the TSC2300 is via a standard SPI serial interface. This interface requires that the slave select
signal be driven low to communicate with the TSC2300. Data is then shifted into or out of the TSC2300 under
control of the host microprocessor, which also provides the serial data clock.
Control of the TSC2300 and its functions is accomplished by writing to different registers in the TSC2300. A
simple command protocol is used to address the 16-bit registers. Registers control the operation of the touch
screen A/D converter, keypad scanner, and audio codec.
The result of measurements made will be placed in the TSC2300’s memory map and may be read by the host at
any time. Three signals are available from the TSC2300 to indicate that data is available for the host to read. The
DAV output indicates that an analog-to-digital conversion has completed and that data is available. The KBIRQ
output indicates that an unmasked key on the keypad has been pressed and de-bounced. The PENIRQ output
indicates that a touch has been detected on the touch screen.
A typical application of the TSC2300 is shown in Figure 44.
