PRELIMINARY DATA SHEET
DESCRIPTION
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.
