16Kbit Serial CMOS EEPROM MICROWIRE™ Synchronous Bus
General Description
FM93C86A is a 16,384-bit CMOS non-volatile EEPROM organized as 1024 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 compatible to many of standard Microcontrollers and Microprocessors. This device offers a pin ORG, using which, the user can select the format of the data 16-bit or 8-bit. If ORG is tied to GND, then 8-bit format is selected, while if ORG is tied to VCC, then 16-bit format is selected. There are 7 instructions implemented on the FM93C86A for various Read, Write, Erase, and Write Enable/Disable operations. This device is fabricated using Semiconductor floating-gate CMOS process for high reliability, high endurance and low power consumption
