Memory IC FAQ

Does the MB85RC512TYPN-GS-AME1 require an acknowledge polling sequence after writing?

No, the device does not require acknowledge polling. It performs high-speed write operations, allowing immediate continuation of communication after the stop condition.

How is the device address configured on the I2C bus?

The device address is determined by the logic levels applied to the external hardware pins A0, A1, and A2. These pins allow up to eight devices to be connected to the same bus.

What is the function of the WP pin?

The Write Protect (WP) pin disables write operations when set to a high level. When low or left open, the memory array remains writable. Reading is always enabled regardless of the WP state.
