Product Overview
1.1
Outline
CW6632B is a highly integrated system on chip for Bluetooth v3.0 with Enhanced Data Rate (EDR). This SOC is
backward-compatible with Bluetooth 2.1, 2.0 and 1.2 systems. The Bluetooth chip supports a data rate of
1M/2M/3Mbps. It has SSOP28 packaging, stereo audio output with AUX input, and external flash. It integrates an
abundant amount of peripherals (full-duplex UART, SPI, SD, IIC (FM function)), and audio interface. In addition, this
SOC supports audio playback from SD, USB.
