The I2C slave/SPI master-slave module provides 50/100/400
kHz communication over two wires. SPI communication over
three or four wires runs at speeds of 46.9 kHz to 3 MHz (lower
for a slower system clock).
The I2C hardware address recognition feature reduces the
already low power consumption by eliminating the need for
CPU intervention until a packet addressed to the target device
is received.
Low Voltage Detection (LVD) interrupts can signal the
application of falling voltage levels, while the advanced POR
(Power-On-Reset) circuit eliminates the need for a system
supervisor.
An internal reference provides an absolute reference for capac-
itive sensing.
A register-controlled bypass mode allows the user to disable
the LDO.
Standard Cypress PSoC IDE tools are available for debugging
the CY8C20x36/46/66/96 family of parts. However, the
additional trace length and a minimal ground plane in the Flex-
Pod can create noise problems that make it difficult to debug
the design. A custom bonded On-Chip Debug (OCD) device is
available in an 48-pin QFN package. The OCD device is
recommended for debugging designs that have high current
and/or high analog accuracy requirements. The QFN package
is compact and is connected to the ICE through a high density
connector.
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 PSoC
Technical Reference Manual for CY8C20x36/46/66/96 PSoC
Devices.
