SPI Serial E ²PROM with Block Lock ^™Protection

FEATURES

DESCRIPTION

The X25170 is a CMOS 16384-bit serial E2PROM,

internally organized as 2K x 8. The X25170 features a

•5MHz Clock Rate

•SPI Modes (0,0 & 1,1)

•2K 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

—<1µA standby current

—<5mA active current

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

number of devices to share the same bus.

•2.5V To 5.5V Power Supply

•Block Lock Protection

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

The X25170 also features two additional inputs that

provide the end user with added flexibility. By asserting

•Built-In Inadvertent Write Protection

—Power-up/power-down protection circuitry

the HOLD input, the X25170 will ignore transitions on its

inputs, thus allowing the host to service higher prior-

—Write enable latch

—Write protect pin

•Self-Timed Write Cycle

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

to the X25170 (disabling all write attempts to the

status register), thus providing a mechanism for limiting end

user 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 X25170 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
