... SDA bus checking the device type identifier being transmitted. Upon receiving a 1010 code and appropri- ate device select bits, the slave device outputs an acknowledge signal on the SDA line. Depending on the state of the R/W bit, the 24LC32 will select a read or write operation. FIGURE 3-3: ADDRESS SEQUENCE BIT ASSIGNMENTS ...

... Page Write The write control byte, word address and the first data byte are transmitted to the 24LC32 in the same way byte write. But instead of generating a stop condi- tion, the master transmits up to eight pages of eight data bytes each (64 bytes total) which are temporarily stored in the on-chip page cache of the 24LC32 ...

... This is done by sending the word address to the 24LC32 as part of a write operation (R/W bit set to 0). After the word address is sent, the master generates a start condition following the acknowledge. This termi- nates the write operation, but not before the internal address pointer is set ...

... Multiple Devices The device select bits A2, A1, A0 can be used to expand the contiguous address space for up to 256K bits by adding up to eight 24LC32's on the same bus. In this case, software can use A0 of the control byte as address bit A12 address bit A13, and A2 as address bit A14 ...

... PIN DESCRIPTIONS 7.1 A0, A1, A2 Chip Address Inputs The A0..A2 inputs are used by the 24LC32 for multiple device operation and conform to the two-wire bus stan- dard. The levels applied to these pins define the address block occupied by the device in the address map. A particular device is selected by transmitting the corresponding bits (A2, A1, A0) in the control byte (Figure 3-3) ...
