OVERVIEW
The S24VP04 is a 4K-bit serial E²PROM memory inte-
grated with a precision V_CC sense circuit. The sense
circuit will disable write operations whenever V_CC falls
below the V_LOCK voltage. It is fabricated using SUMMIT’s
advanced CMOS E²PROM technology and is suitable for
both 3 and 5 volt systems.
The S24VP04 is internally organized as 512 x 8. It fea-
tures the I²C serial interface and software protocol allow-
ing operation on a simple two-wire bus.
