Additional System Resources

System Resources, some of which are listed in the previous sections, 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 follow:

■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 may be generated using digital PSoC blocks as clock dividers.

■A multiply accumulate (MAC) provides a fast 8-bit multiplier with 32-bit accumulate, to assist in both 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 are 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.
