X24256A8I-1.8 数据手册

Preliminary

256K

X24256

32K x 8 Bit

400KHz 2-Wire Serial E²PROM

FEATURES

DESCRIPTION

• 400KHz 2-Wire Serial Interface

—Schmitt Trigger Input Noise Suppression

—Output Slope Control for Ground Bounce

Noise Elimination

The X24256 is a CMOS Serial E²PROM, internally

organized 32K x 8. The device features a serial inter-

face and software protocol allowing operation on a

simple two wire bus.

• Longer Battery Life With Lower Power

—Active Read Current Less Than 1mA

—Active Write Current Less Than 3mA

—Standby Current Less Than 1µA

• 1.8V to 3.6V, 2.5V to 5.5V and 4.5V to 5.5V Power

Supply Versions

Two device select inputs (S –S ) allow up to four

devices to share a common two wire bus.

These pins have internal pull downs, so they are read

as LOW if not connected.

A WP pin, when pulled HIGH prevents any nonvolatile

writes to the array. When not connected WP is pulled

LOW, so the device is not normally protected.

• 64 Byte Page Write Mode

—Minimizes Total Write Time Per Word

• Internally Organized 32K x 8

• Bidirectional Data Transfer Protocol

• Self-Timed Write Cycle

—Typical Write Cycle Time of 5ms

• High Reliability

Xicor E²PROMs are designed and tested for applica-

tions requiring extended endurance. Inherent data

retention is greater than 100 years.

—Endurance: 100,000 Cycles

—Data Retention: 100 Years

• 8-Lead XBGA

• 8-Lead SOIC

• 14-Lead TSSOP
