Additional System Resources
System Resources provide additional capability useful for
complete systems. Additional resources include low voltage
detection and power on reset. Brief statements describing the
merits of each system resource are presented below.
■ There is a digital module in CY8C20x34 devices that imple-
ments an I²C slave, SPI slave, or SPI master interface.The I²C
slave mode provides 0 to 400 kHz communication over two
wires. The SPI master and slave modes provide communi-
cation over three or four wires at frequencies of 46.9 kHz to
12 MHz (lower for a slower system clock).
■ Low Voltage Detection (LVD) interrupts signal the application
of falling voltage levels, while the advanced Power On Reset
(POR) circuit eliminates the need for a system supervisor.
■ An internal voltage reference provides an absolute reference
for capacitive sensing.
■ The 3.0V/2.4V/1.8V fixed output, low dropout regulator (LDO)
provides regulation for I/Os. A register controlled bypass mode
enables the user to disable the LDO.
Getting Started
The quickest way to understand PSoC silicon is to read this data
sheet and then use the PSoC Designer Integrated Development
Environment (IDE). This data sheet is an overview of the PSoC
integrated circuit and presents specific pin, register, and
electrical specifications.
For in depth information, along with detailed programming
details, see the Technical Reference Manual for this PSoC
device.
For up-to-date ordering, packaging, and electrical specification
information, see the latest PSoC device data sheets on the web
