AL3201

We make the parts that set creative people free General Description The AL3201 (SCR, or Single Chip Reverb) is a one chip reverb solution that is compact, easy to use, and yet quite powerful. Built-in DRAM eliminates the need for wide bus connections to external RAM, and the choice of built-in programs and a user programmable RAM allows instant usability or custom program design. Features 16 internal ROM programs consisting of halls, rooms, plates, delays, chorus, flange, vocal cancel, and rotary speaker emulation. Serially programmable SRAM (Writable Control Store – WCS) for program development or dynamically changing programs Programs run at 128 instructions per word clock. (6 MIPS @ 48kHz sampling frequency.) 32k location DRAM provides over 0.68s of delay at 48kHz sampling frequency. Internal crystal oscillator circuit eliminates need for discrete external passive components. Internal voltage regulators allow operation at both 5V and 3.3V VDD. Internal 1000pF bypass capacitor to reduce voltage swings at the rails. Applications Personal stereos with reverb functions. Extremely portable guitar effects boxes. Karaoke machines utilizing the vocal cancel program. Hardware reverb effects for computer sound cards. Ambience settings for car stereos.
