ECT25S80

8M BIT SPI NOR FLASH

Notes:

1. Dual Output data

IO0 = (D6, D4, D2, D0)

IO1 = (D7, D5, D3, D1)

2. Dual Input Address

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

3. Quad Output Data

IO0 = (D4, D0,…..)

IO1 = (D5, D1,…..)

IO2 = (D6, D2,…..)

IO3 = (D7, D3,…..)

4. Quad Input Address

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

5. Fast Read Quad I/O Data

IO0 = (x, x, x, x, D4, D0,…)

IO1 = (x, x, x, x, D5, D1,…)

IO2 = (x, x, x, x, D6, D2,…)

IO3 = (x, x, x, x, D7, D3,…)

6. Security Registers Address:

Security Register0: A23-A16=00h, A15-A8=00h, A7-A0= Byte Address;

Security Register1: A23-A16=00h, A15-A8=01h, A7-A0= Byte Address;

Security Register2: A23-A16=00h, A15-A8=02h, A7-A0= Byte Address;

Security Register3: A23-A16=00h, A15-A8=03h, A7-A0= Byte Address;

Security Register 0 can be used to store the Flash Discoverable Parameters,
