6 / 15 page CAT25010, CAT25020, CAT25040 http://onsemi.com 6 Byte Write Once the WEL bit is set, the user may execute a write sequence, by sending a WRITE instruction, a 8−bit address and data as shown in Figure 5. For the CAT25040, bit 3 of the write instruction opcode contains A8 address bit. Internal programming will start after the low to high CS transition. During an internal write cycle, all commands, except for RDSR (Read Status Register) will be ignored. The RDY bit will indicate if the internal write cycle is in progress (RDY high), or the device is ready to accept commands (RDY low). Page Write After sending the first data byte to the CAT25010/20/40, the host may continue sending data, up to a total of 16 bytes, according to timing shown in Figure 6. After each data byte, the lower order address bits are automatically incremented, while the higher order address bits (page address) remain unchanged. If during this process the end of page is exceeded, then loading will “roll over” to the first byte in the page, thus possibly overwriting previously loaded data. Following completion of the write cycle, the CAT25010/20/40 is automatically returned to the write disable state. Figure 5.
