25AA320-I/SN

The Serial Electrically-Erasable Programmable Read-Only Memory (EEPROM) on the Atmel® AT25320B/640B has 32,768-/65,536-bits and is divided into 4,096/8,192 words with 8 bits each. The device is prepared for usage in a wide range of industrial and commercial settings where moderate and low-voltage functioning are critical requirements. The 8-lead JEDEC SOIC, 8-lead TSSOP, 8-lead UDFN, 8-lead XDFN, and 8-ball VFBGA packages for the AT25320B/640B are available in compact sizes. A 3-wire interface made up of Serial Data Input (SI), Serial Data Output (SO), and Serial Clock is used to access and enable the AT25320B/640B. (SCK). No further erase cycle is necessary before Write since every programming cycle is fully self-timed. Programming one of the four blocks of write security into the status register activates block write protection. For added data security, separate instructions for programme enable and programme disable are given. The WP pin offers hardware data protection to guard against unintentional write attempts to the status register. Any serial communication can be halted using the HOLD pin without having to restart the serial sequence.

The 24AA512/24LC512/24FC512 (24XX512*) from Microchip Technology Inc. is a 64K x 8 (512 Kbit) Serial Electrically Erasable PROM that can operate over a wide voltage range (1.7V to 5.5V). It was created for cutting-edge, low-power applications including data collection and personal communications. Additionally, this device has a page write capacity of up to 128 bytes of information. Both random and sequential readings up to the 512K barrier are supported by this device. Up to eight devices can share a bus with functional address lines, providing a maximum address space of 4 Mbit. The common 8-pin plastic DIP, SOIJ, SOIC, TSSOP, DFN, and 14-lead TSSOP packaging are also available for this component. The 8-lead Chip Scale package is another option for the 24AA512.
