DESCRIPTION
The X24042 is a CMOS 4,096 bit serial E²PROM,
internally organized 512 x 8. The X24042 features a
serial interface and software protocol allowing operation
on a simple two wire bus.
The X24042 is fabricated with Xicor’s advanced CMOS
Textured Poly Floating Gate Technology.
The X24042 utilizes Xicor’s proprietary Direct Write^TM
cell providing a minimum endurance of 100,000 cycles
and a minimum data retention of 100 years.
