DESCRIPTION

GP522

The GP522 is a single memory controller chip, designed as an

array of resistors used to control functions of any signal

processing integrated circuit. Controller consists of eight

digitally programmable resistors and one switch. The GP522

can be programmed by any programmer supporting

communication standard for programmable devices P/N

30381-00.
