... The CAT25010/20/ 1K/2K/4K Bit SPI Serial CMOS EEPROM internally organized as 128x8/256x8/ 512x8 bits. Catalyst’s advanced CMOS Technology substantially reduces device power requirements. The CAT25010/20/40 features a 16-byte page write buffer. The device operates via the SPI bus serial interface and is enabled though a Chip Select (CS). In addition to the ...

... CAT25010/20/40. Input data is latched on the rising edge of the serial clock for SPI modes (0, 0 & 1, 1). Serial Output SO is the serial data output pin. This pin is used to transfer data out of the CAT25010/20/40. During a read cycle, data is shifted out on the falling edge of the serial t t ...

... Chip Select the Chip select pin. CS low enables the CAT25010/ 20/40 and CS high disables the CAT25010/20/40. CS high takes the SO output pin to high impedance and forces the devices into a Standby Mode (unless an internal write operation is underway) The CAT25010/ 20/40 draws ZERO current in the Standby mode. A high to low transition required prior to any sequence being initiated ...

... The part is selected by pulling CS low. The 8-bit read instruction is transmitted to the CAT25010/20/40, followed by the 8-bit address for CAT25010/20/40 (for the 25040, bit 3 of the read data instruction contains address A8). After the correct read instruction and address are sent, the data stored in the memory at the selected address is shifted out on the SO pin ...

... Note: Dashed Line= mode (1, 1) – – – – – The CAT25010/20/40 powers Write Disable state. Prior to any write instructions, the WREN instruction must be sent to CAT25010/20/40. The device goes into Write enable state by pulling the CS low and then clocking the WREN instruction into CAT25010/20/40. ...
