Description
The AT25128 provides 131,072 bits of serial electrically erasable programmable read
only memory (EEPROM) organized as 16,384 words of 8 bits each. The device is
optimized for use in many industrial and commercial applications where low power
and low voltage operation are essential. The AT25128 is available in space saving
8-pin PDIP, JEDEC SOIC, and 14-pin and 20-pin TSSOP packages.

... Description (Continued) The AT25128 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 self-timed, and no separate ERASE cycle is required before WRITE. BLOCK WRITE protection is enabled by programming the status register with one of four blocks of write protection ...

... Functional Description The AT25128 is designed to interface directly with the syn- chronous serial peripheral interface (SPI) of the 6805 and 68HC11 series of microcontrollers. The AT25128 utilizes an 8 bit instruction register. The list of instructions and their operation codes are contained in Table 1. All instructions, addresses, and data are trans- ferred with the MSB first ...
