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 H = Sleep mode = Mute
ID code
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.
ID1, ID3 ID2 = High
=Low
ID4 = Equal to IDSW

3.Mute
TE CH
T62M0001A
(1) Easy mode Automatic mute upon changing delay time, cancelling SLEEP mode and power on. (2) u-COM MUTE=H : mute. MUTE=L : automatic mute. Automatic mute : Delay signal before change mode Delay signal after change mode
(a) Upon changing delay time Delay signal
(b) Upon cancel sleep mode Delay signal
Power on (c) Upon power on
4.SLEEP mode
SLEEP data is : H=clock and RAM stop to reduce circuit current (SLEEP mode) L=normal operation
5.System reset
Automatically reset power-on. The reset time is about 120 m second. Delay time is set at 147.5 m second.
