8-Pin PDIP, 8-Pin EIAJ SOIC, and 8-Pin Leadless Array Package

Description

The AT25HP256/512 provides 262,144/524,288 bits of serial electrically erasable programmable read only memory (EEPROM) organized as 32,768/65,536 words of 8-bits each. The device is optimized for use in many industrial and commercial applications where high-speed, low-power, and low-voltage operation are essential. The AT25HP256/512 is available in a space saving 8-pin PDIP (AT25HP256/512), 8-pin EIAJ SOIC (AT25HP256), and 8-pin Leadless Array (AT25HP256/512) packages. In

addition, the entire family is available in 5.0V (4.5V to 5.5V), 2.7V (2.7V to 5.5V), and 1.8V (1.8V to 3.6V) versions.

The AT25HP256/512 is enabled through the Chip Select pin (CS) and accessed via a 3-wire interface consisting of Serial Data Input (SI), Serial Data Output (SO), and Serial Clock (SCK). All programming cycles are completely selftimed, and no separate ERASE cycle is required before WRITE.

BLOCK WRITE protection is enabled by programming the status register with top ¼, top ½ or entire array of write protection. Separate program enable and program disable instructions are provided for additional data protection.

Hardware data protection is provided via the WP pin to protect against inadvertent write attempts to the status register. The HOLD pin may be used to suspend any serial communication without resetting the serial sequence.
