Does any one experience in the use of SPI serial EEPROM X25020 from Xicor? I had got so many problems on such I.C. Is there any other bands that will be more reliable? I had got 50% of the faulty I.C. in different circuities.
there are a number of makers of serial spi eeproms: microchip, st, catalyst.
However, a failure rate that high is very likely to be either incorrect circuit design or impropper handling. If a company had that high a defect rate, they would be out of business in short order.
