Pin Function Description
Address Inputs (A18-A31) These pins represent the address bus for accessing memory locations in the device. These are used to select the internal memory location during read or write operations. Data Input/Output (I/O0-I/O7) These pins are the data bus that carry data to and from the memory. They are used for both reading and writing data, with each pin representing one bit of data. Control Pins: CE# (Chip Enable): This is used to activate the memory device. When low, the device is enabled; when high, the device is disabled. WE# (Write Enable): Used to control write operations. A low level enables writing to the memory. OE# (Output Enable): Controls the output of the memory. A low level enables the data output from the device. RESET#: Resets the memory to its initial state. This pin is active low. Power Pins: VCC: Provides the supply voltage (typically 3.3V or 5V). VSS: The ground pin. No Connection Pins (NC) These pins do not connect to anything internally in the device and are reserved.3. 20 Common FAQs for S29AL016J70TFI020 Flash Memory
