X24C04 Datasheet | Xicor

FEATURES DESCRIPTION The X24C04 is a CMOS 4096 bit serial E2PROM, internally organized 512 x 8. The X24C04 features a serial interface and software protocol allowing operation on a simple two wire bus. The X24C04 is fabricated with Xicor’s advanced CMOS Textured Poly Floating Gate Technology. The X24C04 utilizes Xicor’s proprietary Direct Write™ cell providing a minimum endurance of 100,000 cycles and a minimum data retention of 100 years. - - - - - - - - 2.7V to 5.5V Power Supply Low Power CMOS - Active Read Current Less Than 1 m A - Active Write Current Less Than 3 m A - Standby Current Less Than 50 µA Internally Organized 512 x 8 2 Wire Serial Interface - Bidirectional Data Transfer Protocol Sixteen Byte Page Write Mode - Minimizes Total Write Time Per Byte Self Timed Write Cycle - Typical Write Cycle Time of 5 ms High Reliability - Endurance: 100,000 Cycles - Data Retention: 100 Years 8 Pin Mini-DIP, 8 Pin SOIC and 14 Pin SOIC Packages FUNCTIONAL DIAGRAM (8) VCC (4) VSS (7) TEST START CYCLE START STOP LOGIC CONTROL LOGIC SLAVE ADDRESS REGISTER +PARATOR XDEC E2PROM 32 X 128 H.V.

Serial Data (SDA) SDA is a bidirectional pin used to transfer data into and out of the device. It is an open drain output and may be wire-ORed with any number of open drain or open collector outputs. An open drain output requires the use of a pull-up resistor. For selecting typical values, refer to the Pull-Up Resistor selection graph at the end of this data sheet. Address (A0) A0 is unused by the X24C04, however, it must be tied to VSS to insure proper device operation. Address (A1, A2) The...
