FEATURES 2.7V to 5.5V Power Supply Low Power CMOS —Active Read Current Less Than 1mA —Active Write Current Less Than 3mA —Standby Current Less Than 1∝A Internally Organized 8192 x 8 New Programmable Block Lock Protection —Software Write Protection —Programmable hardware Write Protect Block Lock (0, 1/4, 1/2, or all of the E2PROM array)
DESCRIPTION 2 The X24645 is a CMOS 65,536-bit serial E PROM, internally organized 8192 x 8. The X24645 features a
serial interface and software protocol allowing operation on a simple two wire bus.
Two device select inputs (S1, S2) allow up to four devices to share a common two wire bus. A Write Protect Register at the highest address location, 1FFFh, provides three new write protection features: Software Write Protect, Block Write Protect, and Hardware Write Protect. The Software Write

Protect feature prevents any nonvolatile writes to the X24645 until the WEL bit in the write protect register is
set. The Block Write Protection feature allows the user to individually write protect four blocks of the array by
