The device is optimized for use in many industrial and commercial applications where low power and low voltage operation are essential. The AT59C11/22/13 is available in space saving 8-pin PDIP and 8-pin EIAJ SOIC packages. The AT59C11/22/13 is enabled through the Chip Select pin (CS), and accessed via a 4-wire serial interface consisting of Data Input (DI), Data Output (DO), and Clock (CLK). Upon receiving a READ instruction at DI, the address is decoded and the data is clocked out serially on the data output pin DO, the WRITE cycle is completely selftimed and no separate ERASE cycle is required before WRITE. The WRITE cycle is only enabled when the part is in the ERASE/WRITE ENABLE state. Ready/Busy status can be monitored upon completion of a programming operation by polling the Ready/Busy pin. The AT59C11/22/13 is available in 5.0V ± 10%, 2.7V to 5.5V and 2.5V to 5.5V versions.
