2M BIT SPI NOR FLASH

VER 1.1

Notes:

Data bytes are shifted with Most Significant Bit first. Byte fields with data in parenthesis “( )” indicate

data output from the device.

The Status Register contents and Device ID will repeat continuously until /CS terminates the

instruction.

At least one byte of data input is required for Page Program, Dual Page Program, Quad Page

Program and Program Security Registers, up to 256 bytes of data input. If more than 256 bytes of data

are sent to the device, the addressing will wrap to the beginning of the page and overwrite previously

sent data.

Write Status Register (01h) can also be used to write Status Register-1&2, see section Write Status

Security Register Address:

Security Register 1

A23-16 = 00h

A15-9 = 0001000

A8-0 = byte address

Security Register 2

A23-16 = 00h

A15-9 = 0010000

A8-0 = byte address

Security Register 3

A23-16 = 00h

A15-9 = 0011000

A8-0 = byte address

Dual SPI address input format:

IO0 = A22, A20, A18, A16, A14, A12, A10, A8, A6, A4, A2, A0, M6, M4, M2, M0

IO1 = A23, A21, A19, A17, A15, A13, A11, A9, A7, A5, A3, A1, M7, M5, M3, M1

Dual SPI data output format:

IO0 = (D6, D4, D2, D0)

IO1 = (D7, D5, D3, D1)

Quad SPI address input format:

IO0 = A20, A16, A12, A8, A4, A0, M4, M0

IO1 = A21, A17, A13, A9, A5, A1, M5, M1

IO2 = A22, A18, A14, A10, A6, A2, M6, M2

IO3 = A23, A19, A15, A11, A7, A3, M7, M3

Quad SPI data output format:

IO0 = (D4, D0, …..)

IO1 = (D5, D1, …..)

IO2 = (D6, D2, …..)

IO3 = (D7, D3, …..)

10.

Fast Read Quad I/O data output format:

IO0 = (x, x, x, x, D4, D0, D4, D0)

IO1 = (x, x, x, x, D5, D1, D5, D1)

IO2 = (x, x, x, x, D6, D2, D6, D2)

IO3 = (x, x, x, x, D7, D3, D7, D3)
