Supervisory Circuit w/Serial E²PROM

FEATURES

DESCRIPTION

• Low Vcc Detection and Reset Assertion

—Reset Signal Valid to Vcc=1V

• Save Critical Data With Block Lock^TMProtection

—Block Lock^TMProtect 0, 1/4, 1/2 or all of

Serial E²PROM Memory Array

• In Circuit Programmable ROM Mode

• Long Battery Life With Low Power Consumption

—<1µA Max Standby Current

—<5mA Max Active Current during Write

—<400µA Max Active Current during Read

• 1.8V to 3.6V, 2.7V to 5.5V and 4.5V to 5.5V Power

Supply Operation

• 2MHz Clock Rate

• Minimize Programming Time

—32 Byte Page Write Mode

—Self-Timed Write Cycle

—5ms Write Cycle Time (Typical)

• SPI Modes (0,0 & 1,1)

These devices combines two popular functions, Supply

Voltage Supervision and Serial E²PROM Memory in one

package. This combination lowers system cost, reduces

board space requirements, and increases reliability.

The user’s system is protected from low voltage condi-

tions by the devices low Vcc detection circuitry. When

Vcc falls below the minimum Vcc trip point, the system is

reset. RESET/RESET is asserted until Vcc returns to

proper operating levels and stabilizes.

The memory portion of the device is a CMOS Serial

E²PROM array with Xicor’s Block Lock^TMProtection. The

array is internally organized as x 8.The device features a

Serial Peripheral Interface (SPI) and software protocol

allowing operation on a simple four-wire bus.

The device utilizes Xicor’s proprietary Direct Write^TMcell,

providing a minimum endurance of 100,000 cycles per

sector and a minimum data retention of 100 years.

• Built-in Inadvertent Write Protection

—Power-Up/Power-Down Protection Circuitry

—Write Enable Latch

—Write Protect Pin

• High Reliability

• Available Packages

—14-Lead SOIC (X2564X)

—14-Lead TSSOP (X2532X, X2516X)

—8-Lead SOIC (X2532X, X2516X)
