CAV25256VE-GT3

onsemi · EEPROM · SOIC-8

CAV25256VE-GT3 from onsemi, 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, overbar in datasheet). Enables the device; must transition high-to-low to start a command and low-to-high to end it. When high, SO is tri-stated and the device is in Standby.
2 SO output Serial Data Output (MISO). Shifts data out on the falling edge of SCK. Tri-stated when CS is high.
3 WP input Write Protect (active-low). When WP is low and the WPEN bit in the Status Register is 1, writes to the Status Register are disabled (hardware write protection).
4 VSS power_in Ground reference for the device.
5 SI input Serial Data Input (MOSI). 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 SPI host. Synchronizes communication between the host and CAV25256. Maximum 10 MHz at VCC = 5 V.
7 HOLD input Hold Transmission Input (active-low). Pauses an in-progress SPI transaction without terminating it; drive HOLD low with SCK low to pause, and back high with SCK low to resume. Tie to VCC directly or via a resistor when unused.
8 VCC power_in Positive supply voltage, 2.5 V to 5.5 V operating range.
