FM25L16B-GTR from Infineon, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | CS | input | Chip Select (active LOW). Activates the device and gates SCK internally; when HIGH, the device enters low-power standby mode, ignores other inputs, and tri-states SO. A falling edge on CS must occur before every opcode. |
| 2 | SO | tri_state | Serial Output (MISO). Data output pin driven only during a read; tri-stated at all other times, including when HOLD is LOW. Data transitions occur on the falling edge of SCK. |
| 3 | WP | input | Write Protect (active LOW). When WPEN = 1 in the Status Register, driving WP LOW inhibits writes to the Status Register (protecting the block-protect bits). Tie to VDD if unused. |
| 4 | VSS | power_in | Ground reference for the device. Must be connected to system ground. |
| 5 | SI | input | Serial Input (MOSI). Data/command input, sampled on the rising edge of SCK and ignored otherwise. Should always be driven to a valid logic level to meet IDD specifications. SI may be tied to SO for a single-wire data interface. |
| 6 | SCK | input | Serial Clock (0 to 20 MHz). All I/O is synchronized to SCK: inputs are latched on the rising edge and outputs are driven on the falling edge. Supports SPI modes 0 and 3. |
| 7 | HOLD | input | HOLD (active LOW). Suspends the current serial operation when driven LOW while SCK is LOW; SCK and CS transitions are ignored during hold. All HOLD transitions must occur while SCK is LOW. Tie to VDD if unused. |
| 8 | VDD | power_in | Power supply input, 2.7 V to 3.6 V (3.3 V typ). Typical standby current 3 uA; active current 0.2 mA at 1 MHz SCK, 3 mA at 20 MHz SCK. |
