CAT25640 Datasheet | onsemi

EEPROM Serial 64-Kb SPI CAT25640 Description The CAT25640 is a EEPROM Serial 64- Kb SPI device internally organized as 8Kx8 bits. This Features a 64- byte page write buffer and supports the Serial Peripheral Interface (SPI) protocol. The device is enabled through a Chip Select (CS) input. In addition, the required bus signals are clock input (SCK), data input (SI) and data output (SO) lines. The HOLD input may be used to pause any serial munication with the CAT25640 device. The device Features software and hardware write protection, including partial as well as full array protection. Features - 20 MHz (5 V) SPI patible - 1.8 V to 5.5 V Supply Voltage Range - SPI Modes (0,0) & (1,1) - 64- byte Page Write Buffer - Self- timed Write Cycle - Hardware and Software Protection - Block Write Protection - Protect 1/4, 1/2 or Entire EEPROM Array - Low Power CMOS Technology - 1,000,000 Program/Erase Cycles - 100 Year Data Retention - Industrial and Extended Temperature Range - SOIC, TSSOP 8- lead and UDFN 8- pad Packages - This Device is Pb- Free, Halogen Free/BFR Free, and Ro HS pliant HOLD SCK VSS Figure 1.
