AT25080B-SSHL-T

Microchip · EEPROM · SOIC-8

AT25080B-SSHL-T from Microchip, 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 SPI Chip Select, active-low. A high-to-low transition enables the device; a low-to-high transition ends the current instruction and puts the SO output into high-impedance.
2 SO output Serial Data Output. Data is shifted out on the falling edge of SCK; high-impedance when CS is deasserted.
3 WP input Write Protect, active-low. When low, all write operations to the status register are inhibited, providing hardware protection of the block-protection bits.
4 GND power_in Ground reference for the device supply and all I/O signals.
5 SI input Serial Data Input. Instructions, addresses, and data are shifted in on the rising edge of SCK, MSB first.
6 SCK input Serial Clock. Provides the timing reference for SPI transfers. Supports up to 20 MHz at VCC = 4.5-5.5 V, 10 MHz at 2.5-5.5 V, and 5 MHz at 1.8-5.5 V.
7 HOLD input Suspends serial input, active-low. When low with CS also low, the current SPI operation is paused without resetting the serial sequence; SO goes high-impedance and SI/SCK are ignored.
8 VCC power_in Positive supply voltage, 1.8 V to 5.5 V. Typical supply current is 7.5 mA read / 4.0 mA read+write at 5 V, 20 MHz; standby current is <0.1 uA at 1.8 V.
