CAT25640YI-GT3

onsemi · EEPROM · TSSOP-8

CAT25640YI-GT3 from onsemi, in a TSSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 CS input Chip select input enables the device; a high-to-low transition starts each session and a low-to-high transition ends it, and SO is tri-stated while CS is high.
2 SO tri_state Serial data output shifts data out on the falling edge of SCK in SPI modes (0,0) and (1,1) and is high impedance when CS is high or HOLD is asserted.
3 WP input Write protect input allows all write operations when high; when low with the WPEN bit set to 1, writes to the Status Register are disabled.
4 VSS power_in Ground reference for the device.
5 SI input Serial data input accepts op-codes, addresses and data, and is latched on the rising edge of SCK.
6 SCK input Serial clock input provided by the host to synchronize communication with the device.
7 HOLD input Hold input pauses serial transmission when taken low while SCK is low and resumes when taken high while SCK is low; tie to VCC when not used.
8 VCC power_in Power supply input, 1.8 V to 5.5 V.
