The Spin Semiconductor FV-1 chip is a complete reverb solution in a single IC.

With integrated stereo ADC and DACs, the FV-1 can be treated like any other analog component in your products signal path.

The FV-1 can access a total of 16 programs, 8 are built in to the internal ROM and the designer may elect to connect a serial EEPROM with 8 additional programs. By using an external EEPROM, the designer can create a custom program set without the need for a microprocessor in the system.

With 3 potentiometer inputs, programs may have real time variable parameters such as decay time in a reverb, rate and depth in a chorus or frequency in a filter. These inputs are available as coefficients to your program and may be used independently of each other.

The DSP module's rich instruction set allows users to program effects of all kinds. With instructions like LOG and EXP, users can easily program audio expansion and compression routines. Integrated digital LFOs and ramp generators allow for programming chorus, flange and pitch shift.

A FV-1 Demonstration Board is available for the multi effects unit - please see SPN1001-DEVB.
