... SERIAL E PROM DATA AND ADDRESS (SDA) SCL Xicor, 1995, 1996 Patents Pending 7026 3/27/97 T0/C0/D0 SH X24641 400 KHz 2-Wire Serial E DESCRIPTION The X24641 is a CMOS Serial E internally organized The device features a serial interface and software protocol allowing opera- tion on a simple two wire bus. The bus operates at 400KHz all the way down to 1 ...

X24641 DEVICE ADDRESSING Following a start condition, the master must output the address of the slave it is accessing. The first four bits of the Slave Address Byte are the device type identifier bits. These must equal “1010”. The next ...

X24641 Acknowledge Polling The maximum write cycle time can be significantly reduced using Acknowledge Polling. To initiate Acknowledge Polling, the master issues a start condi- tion followed by the Slave Address Byte for a write or read operation. If the ...

X24641 Random Read Random read operation allows the master to access any memory location in the array. Prior to issuing the Slave Address Byte with the R/W bit set to one, the master must first perform a “Dummy” write operation. ...
