FEATURES

DESCRIPTION

The X25320 is a CMOS 32768-bit serial E²PROM,

internally organized as 4K x 8. The X25320 features a

•2MHz Clock Rate

•SPI Modes (0,0 & 1,1)

•4K X 8 Bits

Serial Peripheral Interface (SPI) and software protocol

allowing operation on a simple three-wire bus. The bus

— 32 Byte Page Mode

•Low Power CMOS

signals are a clock input (SCK) plus separate data in (SI)

and data out (SO) lines. Access to the device is con-

—<1µA Standby Current

— <5mA Active Current During Write

•2.7V To 5.5V Power Supply

•Block Lock Protection

— Protect 1/4, 1/2 or all of E²PROM Array

•Built-in Inadvertent Write Protection

trolled through a chip select (CS) input, allowing any

number of devices to share the same bus.

The X25320 also features two additional inputs that

provide the end user with added flexibility. By asserting

the HOLD input, the X25320 will ignore transitions on its

inputs, thus allowing the host to service higher priority

— Power-Up/Power-Down protection circuitry

— Write Enable Latch

interrupts. The WP input can be used as a hardwire input to

the X25320 disabling all write attempts to the status

— Write Protect Pin

•Self-Timed Write Cycle

capability of altering 0, 1/4, 1/2 or all of the memory.

— 5ms Write Cycle Time (Typical)

•High Reliability

— Endurance: 100,000 cycles

— Data Retention: 100 Years

The X25320 utilizes Xicor’s proprietary Direct Write™ cell,

providing a minimum endurance of 100,000 cycles

and a minimum data retention of 100 years.

— ESD protection: 2000V on all pins

•8-Lead PDlP Package

•8-Lead SOIC Package

•14-Lead TSSOP Package
