Notes:
1. Output designates data output from the device.
2. Byte Address or Column Address (CA) only requires CA[11:0], CA[15:12] are considered as dummy bits.
3. Page Address (PA) requires 16 bits. PA[15:6] is the address for 128KB blocks (total 1,024 blocks), PA[5:0]
is the address for 2KB pages (total 64 pages for each block).
4. Logical and Physical Block Address (LBA & PBA) each consists of 16 bits. LBA[9:0] & PBA[9:0] are
effective Block Addresses. LBA[15:14] is used for additional information.
5. Status Register Addresses:
Status Register 1 / Protection Register:
Status Register 2 / Configuration Register:
Status Register 3 / Status Register:
Addr = Axh
Addr = Bxh
Addr = Cxh
6. Dual SPI Address Input (CA15-8 / 2 and CA7-0 / 2) format:
IO0 = x, x, CA10, CA8, CA6, CA4, CA2, CA0
IO1 = x, x, CA11, CA9, CA7, CA5, CA3, CA1
7. Dual SPI Data Output (D7-0 / 2) format:
IO0 = D6, D4, D2, D0, ……
IO1 = D7, D5, D3, D1, ……
8. Quad SPI Address Input (CA15-8 / 4 and CA7-0 / 4) format:
IO0 = x, CA8,
IO1 = x, CA9,
IO2 = x, CA10, CA6,
IO3 = x, CA11, CA7,
CA4,
CA5,
CA0
CA1
CA2
CA3
9. Quad SPI Data Input/Output (D7-0 / 4) format:
IO0 = D4, D0, ……
IO1 = D5, D1, ……
IO2 = D6, D2, ……
IO3 = D7, D3, ……
10. All Quad Program/Read commands are disabled when WP-E bit is set to 1 in the Protection Register.
11. For all Read operations in the Continuous Read Mode, once the /CS signal is brought to high to terminate
the read operation, the device will still remain busy for ~5us (BUSY=1), and all the data inside the Data
buffer will be lost and un-reliable to use. A new Page Data Read instruction must be issued to reload the
correct page data into the Data Buffer.
12. For all Read operations in the Buffer Read Mode, as soon as /CS signal is brought to high to terminate the
read operation, the device will be ready to accept new instructions and all the data inside the Data Buffer
will remain unchanged from the previous Page Data Read instruction.
