Description

The AM93LC86 is the 16384-bit non-volatile serial EEPROM. The AM93LC86 provides efficient non-volatile read/write memory arranged as 1024 words of 16 bits each when the ORG Pin is connected to VCC and 2048 words of 8 bits each when it is tied to ground. The instruction set includes read, write, and write enable/disable functions. The data out pin (DO) indicates the status of the device during the self-timed non-volatile programming cycle.

The self-timed write cycle includes an automatic erase-before-write capability. Only when AM93LC86 is in the write enable state and proper Vcc operation range is the write instruction accepted and thus to protect against inadvertent writes. Data is written in 16 bits per write instruction into the selected register. If chip select (CS) is brought high after initiation of the write cycle, the data output (DO) pin will indicate the read/busy status of the chip.

The AM93LC86 is available in space-saving 8-lead PDIP, SOP and TSSOP packages.
