CAV25128VE-GT3

onsemi · EEPROM · SOIC-8

CAV25128VE-GT3 from onsemi, in a SOIC-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 Active-low chip select input that enables the device; when high, SO is tri-stated and the device is in standby, and each session needs a high-to-low transition at start and low-to-high at end.
2 SO tri_state Serial data output that 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 during hold.
3 WP input Write protect input; when held low with the WPEN bit set to 1, writing to the Status Register is disabled, and all writes are allowed when it is high.
4 VSS power_in Ground.
5 SI input Serial data input that accepts op-codes, addresses and data, latched on the rising edge of SCK in SPI modes (0,0) and (1,1).
6 SCK input Serial clock input from the host used to synchronize communication, with a maximum frequency of 10 MHz.
7 HOLD input Active-low hold input that pauses serial transmission when taken low with SCK low and resumes when taken high; tie to VCC when not used.
8 VCC power_in Power supply, 2.5 V to 5.5 V.
