General Overview:
Device Type: Flash Memory (NOR) Manufacturer: Micron Technology Package Type: FBGA (Fine-pitch Ball Grid Array) Density: 256 Megabits (32 Megabytes) interface : SPI (Serial Peripheral Interface) Operating Voltage: Typically 2.3V to 3.6VPin Functions:
Typically, a Micron SPI NOR flash memory device in a FBGA package may have pins for the following functions:
VCC ( Power Supply) - Pin for the main power supply (typically 2.3V to 3.6V). VSS (Ground) - Pin for ground. SCK (Serial Clock ) - Pin used for the SPI clock signal. MISO (Master In Slave Out) - Pin for data output from the flash memory to the SPI master. MOSI (Master Out Slave In) - Pin for data input to the flash memory from the SPI master. CS (Chip Select) - Pin used to select the device for communication in SPI. WP (Write Protect) - Pin for write protection, preventing accidental write operations. HOLD - Pin for pausing operations (used for pause functionality during SPI communication). RESET - Pin to reset the device. NC (No Connection) - Pins that are not internally connected or used in this specific device.Typical Pinout and Description of FBGA Package:
