2-WIRE CMOS SERIAL E²PROM
FOR DIMM SERIAL PRESENCE DETECT
S-34C02A
S-34C02A is a 2-wired serial E²PROM for DIMM Serial
Presence Detect which operates with low current
consumption and the wide range operation. The S-34C02A
has the capacity of 2K-bit and the organization of 256
words × 8-bit, is able to Page Write and Sequential Read.
S-34C02A has Hardware Protect and Software Protect.
Hardware Protect inhibits Write to all memory area by
connecting the WP pin to V_CC. Software Protect inhibits
Write in 50% of the lower address (the address 00h to 7Fh)
in all memory area by inputting command when the WP pin
is connected to GND or left open.
