FM25L16B-GTR

Infineon · FRAM · SOIC-8

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.
