Additional System Resources
System Resources, some of which have been previously listed,
provide additional capability useful to complete systems. Addi-
tional 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.
■ Digital clock dividers provide three customizable clock fre-
quencies for use in applications. The clocks can be routed to
both the digital and analog systems. Additional clocks can be
generated using digital PSoC blocks as clock dividers.
■ Multiply accumulate (MAC) provides fast 8-bit multiplier with
32-bit accumulate, to assist in general math and digital filters.
■ The decimator provides a custom hardware filter for digital
signal processing applications including the creation of Delta
Sigma ADCs.
■ The I2C module provides 100 and 400 kHz communication
over two wires. Slave, master, and multi-master modes are
all supported.
■ Low Voltage Detection (LVD) interrupts can signal the appli-
cation 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.
■ An integrated switch mode pump (SMP) generates normal
operating voltages from a single 1.2V battery cell, providing a
low cost boost converter.
PSoC Device Characteristics
