EEPROM Serial 1/2/4-Kb SPI CAT25010, CAT25020, CAT25040 Description The CAT25010/20/40 are a EEPROM Serial 1/2/4−Kb SPI devices internally organized as 128x8/256x8/512x8 bits. They feature a 16−byte page write buffer and support the Serial Peripheral Interface (SPI) protocol. The device is enabled through a Chip Select (CS) input. In addition, the required bus signals are a clock input (SCK), data input (SI) and data output (SO) lines. The HOLD input may be used to pause any serial communication with the CAT25010/20/40 device. These devices feature software and hardware write protection, including partial as well as full array protection. Features • 20 MHz (5 V) SPI Compatible • 1.8 V to 5.
