Manual for CPI-WAM002/XX-X
1. Description
CPI’s CPI-WAM002/XX-X audio module is a cost-effective and low-power solution optimized for
wireless transmission of high-
quality digital audio. We use TI’s CC8520/CC8530 IC (Digital I2S I/O) and
CC8521/CC8531 (USB full speed I/O) IC which includes a robust built-in wireless audio transmission
protocol and can control selected external audio devices.
The wireless range is up to 100 meters line of sight with an external PA (TI CC2590). Utilizing
numerous coexistence mechanisms allows CPI-WAM002/XX-X to avoid interfering with, or being
interfered by other 2.4GHz radio systems. Therefore, CPI-WAM002/XX-X has excellent anti-WiFi
performance. CPI-WAM002/XX-X operates autonomously, and can be used with or without an external
MCU. An external host processor can be connected through SPI and control some aspects of its
operation.
Combined with the easy-to-use configuration tool and application reference designs,
CPI-WAM002/XX-XX wireless audio module ensures flexibility, cost-efficiency and a fast
time-to-market.
