FM93CS66
Description
FM93CS66 is a 4096-bit CMOS non-volatile EEPROM organized as 256 x 16-bit array. This device features
MICROWIRE interface which is a 4-wire serial bus with chipselect (CS), clock (SK), data input (DI) and data output (DO) signals. This interface is patible to many of standard Microcontrollers and Microprocessors. FM93CS66 offers programmable write protection to the memory array using a special register called Protect Register. Selected memory locations can be protected against write by programming this Protect Register with the address of the first memory location to be protected (all locations greater than or equal to this first address are then protected from further change). Additionally, this address can be “permanently locked” into the device, making all future attempts to change data impossible. In addition this device features
“sequential read”, by which, entire memory can be read in one cycle instead of multiple single byte read cycles. There are 10 instructions...
