Low Noise (-90dBV typical) Low Distortion (0.17% typical) Built -in 64 K SRAM Sleep Mode Function Two Control Modes Selection: Easy Mode Using Parallel Data u-COM Mode Using Serial Data Auto-Mute Function Built-in Automatic Reset Circuit Pin Compatible with M65831
Digital Sound Processor With 64K SRAM
Description
T62M0001 is a digital echo/surround processor IC utilizing CMOS technology. Analog signal to T62M0001 is digitized by a built-in A/D converter and then stored in the internal memory. After an adjustable delay time, data in the memory is read and converted back to analog signal via the other D/A converter. With the built-in 64K SRAM, T62M0001 can create very high performance echo/surround sound effect and meet the application of A/V system such as CD player VCD,DVD ....etc.

2.u-COM mode (serial data input)
When the pin EASY/ u - COM = "Low" , then in the u-COM mode. The timing is shown as the diagram below:
H Delay time = Sleep mode
H ID code = Mute
This timing chart shows that delay time is set by serial data from u-COM. DATA signal is latched at the falling edge of SCK signal, the last ten datas are set at the rising edge of REQ signal when ID codes are satisfied.
