■ Two multiply accumulates (MACs) provide fast 8-bit multipliers
with 32-bit accumulate, to assist in both general math and
digital filters.
■ Decimator provides a custom hardware filter for digital signal
processing applications including creation of Delta Sigma
ADCs.
■ The I2C module provides 100 and 400 kHz communication over
two wires. Slave, master, multi-master modes are supported.
■ Low Voltage Detection (LVD) interrupts signal the application
of falling voltage levels, while the advanced POR (Power On
Reset) circuit eliminates the need for a system supervisor.
■ An internal 1.3V reference provides an absolute reference for
the analog system, including ADCs and DACs.
■ Versatile analog multiplexer system.
Getting Started
To understand the TrueTouch device, read this data sheet and
use the PSoC Designer Integrated Development Environment
(IDE). This data sheet is an overview of the PSoC integrated
circuit and presents general silicon and electrical specifications.
For in depth touchscreen application information, including
touchscreen specific specifications, read the touchscreen user
module data sheet that is supported by this specific device.
TrueTouch Device Characteristics
Depending on the TrueTouch device selected for a touchscreen
application, characteristics and capabilities of each device
change. Table 1 lists the touchscreen sensing capabilities
available for specific TrueTouch devices. The TrueTouch device
covered by this data sheet is highlighted in this table.

Development Tools
PSoC Designer is a Microsoft® Windows based, integrated
development
environment
for
the
Programmable
System-on-Chip™ (PSoC) devices. The PSoC Designer IDE
and application runs on Windows NT 4.0, Windows 2000,
Windows Millennium (Me), or Windows XP (see Figure 3 on page
5)
PSoC Designer helps the customer to select an operating config-
uration for the PSoC, write application code that uses the PSoC,
and debug the application. This system provides design
database management by project, an integrated debugger with
In-Circuit Emulator, in-system programming support, and the
CYASM macro assembler for the CPUs.
PSoC Designer also supports a high level C language compiler
developed specifically for the devices in the family.
