OVERVIEW
The XL9020 is a cost effective 2,048-bit, nonvolatile,
serial E2PROM designed to directly connect with serial
interface. It is fabricated using EXEL's advanced CMOS
E2PROM technology. The XL9020 provides external
read/write memory arranged as 128 registers of 16 bits
each. Four 8-bit instructions control the operation of the
device, which include read, write, write enable and write
disable. The READY/BUSY pin indicates the status of the
device when polled during the WRITE operation. The data
output pin (DO) also indicates the status of the device
during self-timed nonvolatile programming cycle. To pro-
tect against inadvertent writes, the WRITE instruction is
accepted only while the chip is in the write enabled state.
After the initiation of the write cycle, if Chip Select (CS) is
brought into LOW state, while SK is low, the DO pin will
indicate the READY/BUSY status of the chip.
