CMOS SERIAL E2PROM

S-29530A / 29630A

The S-29530A / 630A series are low power 16K / 32K-bit E2PROM with

a low operating voltage range. They are organized as 1024-word16-bit

and 2048-word16bit, respectively. Each is capable of sequential read,

at which time addresses are automatically incremented in 16-bit blocks.

Standby : 1.0A Max.

Operating : 1.2 mA Max. (VCC=5.5 V)

: 0.4 mA Max. (VCC=2.5 V)

· Wide operating voltage range

Write : 1.8 to 5.5 V

Read : 1.8 to 5.5 V

· Sequential read capable

· Endurance : 106 cycles/word

· Data retention : 10 years
