CAT25320YI-GT3

onsemi · EEPROM · TSSOP-8

CAT25320YI-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 The chip select input enables or disables the device; CS must go high-to-low before each session and low-to-high to end it, and when CS is high SO is tri-stated and the device is in Standby Mode.
2 SO output The serial data output transfers data out of the device 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 The write protect input allows all write operations when held high, and when tied low with the WPEN status register bit set to 1 it disables writing to the Status Register.
4 VSS power_in Ground reference for the device; DC input voltages must not be lower than -0.5 V with respect to ground.
5 SI input The serial data input accepts op-codes, addresses and data, latched on the rising edge of SCK in SPI modes (0,0) and (1,1).
6 SCK input The serial clock input accepts the clock from the host to synchronize communication between host and device.
7 HOLD input The HOLD input pauses serial communication when taken low while SCK is low (SO tri-stated, SI ignored) and resumes when taken high while SCK is low; when unused it should be tied to VCC directly or through a resistor.
8 VCC power_in Power supply input, rated 1.8 V to 5.5 V per the Features list; voltage on any pin must not exceed VCC + 0.5 V.
