The IC has the largest memory among the digital delay series. As it’s design is aimed at high performance, it is best suited to provide radio cassette tape recorders and miniature unit audio system with quality echo function. Being pin patible with the M65830CP / FP and M65843AP / FP, the M65831AP / FP is suitable for upgrading the series. Outline Features - Built-in input / output filters, A-D and D-A conver ters, and memory realize a delay system with only a single chip - Capable of posing low-noise and low-distortion delay system at low cost by ADM system (No=-92d B typ, THD=0.5% typ) - Control mode selections available from 2 kinds : easy mode using parallel data and microputer mode using serial data - Sleep mode can be selected to stop IC functions - Built-in automatic reset circuit Outline 24P4 (AP) 2.54mm pitch 600mil DIP (13.0mm X 31.1mm X 3.8mm) REMENDED OPERATING CONDITIONS Supply voltage range Rated supply voltage VCC,VDD=4.5 to 5.5V VCC,VDD=5.0V Outline 24P2W-A(AFP) 1.27mm pitch 450mil SOP (8.4mm X15.0mm X2.0mm) SYSTEM CONFIGURATION VOCAL CUT HPF LPF HPF KEY CONTROL BASS CTL NORM SEARCH BASS VISS VISS MIC1 MIC AMP MIC2 MIC AMP MIC VOL MIX MIC VOL M65381AP/FP MIX ECHO ECHO VOL MITSUBISHI...
