UDFN8
MUW3 SUFFIX
CASE 517DH
It features a 64−byte page write buffer and supports both the
2
Standard (100 kHz), Fast (400 kHz) and Fast−Plus (1 MHz) I C
protocol.
Write operations can be inhibited by taking the WP pin High (this
protects the entire memory).
On−Chip ECC (Error Correction Code) makes the device suitable
for high reliability applications.
