MICROCHIP ZL38005QCG1

The ZL38005 is a hardware platform designed to support advanced acoustic echo canceller (with noise reduction) firmware applications available from Microsemi. These applications are resident in external memory and are downloaded by the ZL38005 resident boot code during initialization. The ZL38005 Advanced Acoustic Echo Canceller with Noise Reduction platform integrates Microsemi’s Voice Processor (ZVP) DSP Core with a number of internal peripherals. These peripherals include the following: Two independent  CODECs Two PCM ports - ST BUS, GCI, McBSP or SSI operation An I²S interface port A 2048 tap Filter Co-processor (LMS, FIR and FAP realizations) Two Auxiliary Timers and a Watchdog Timer 11 GPIO pins A UART interface A Slave SPI port and a Master SPI port A timing block that supports master and slave operation An IEEE - 1149.1 compatible JTAG port The DSP Core can process up to four 8-bit audio channels, two 16-bit audio channels or two 8-bit and one 16-bit audio channel. These audio channels may originate and terminate with the  CODECs, or be communicated to and from the DSP Core through the PCM ports or the I²S port.
