CY8CLED08
■ The decimator provides a custom hardware filter for digital
signal processing applications including the creation of Delta
Sigma ADCs.
1.1 Additional System Resources
System Resources, some of which have been previously listed,
provide additional capability useful to complete systems.
Additional resources include a multiplier, decimator, switch mode
pump, low voltage detection, and power on reset. Statements
describing the merits of each system resource are below.
■ TheI2Cmoduleprovides100and400kHzcommunicationover
two wires. Slave, master, and multi-master modes are all
supported.
■ Digital clock dividers provide three customizable clock
frequencies for use in applications. The clocks can be routed
to both the digital and analog systems. Additional clocks can
be generated using digital blocks as clock dividers.
■ Low Voltage Detection (LVD) interrupts can signal the appli-
cation offalling 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.
■ Multiply accumulate (MAC) provides fast 8-bit multiplier with
32-bit accumulate, to assist in general math and digital filters.
■ An integrated switch mode pump (SMP) generates normal
operating voltages from a single 1.2V battery cell, providing a
low cost boost converter.
1.2 EZ-Color Device Characteristics
Depending on your EZ-Color device characteristics, the digital and analog systems can have 16, 8, or 4 digital blocks and 12, 6, or 4
analog blocks. The following table lists the resources available for specific EZ-Color device groups. The device covered by this data
sheet is shown in the highlighted row of the table
