AT25160B-SSHL-T

Microchip Tech · EEPROM · SOIC-8

AT25160B-SSHL-T from Microchip Tech, 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 Chip Select; the device is selected when CS is low, and when deselected SI data is not accepted and SO stays high-impedance.
2 SO tri_state Serial Data Output; shifts data out and remains in a high-impedance state when the device is not selected, on an invalid opcode, or during hold.
3 WP input Write Protect; when low with the WPEN bit set to one, writes to the status register are inhibited, and when held high normal read and write operations are allowed.
4 GND power_in Ground.
5 SI input Serial Data Input; receives opcodes, addresses and data, MSB first, and is ignored while the device is deselected or in hold.
6 SCK input Serial Data Clock; always an input, with a maximum frequency of 20MHz at 4.5V to 5.5V.
7 HOLD input Suspends serial communication without resetting the sequence; brought low while SCK is low to pause and high while SCK is low to resume.
8 VCC power_in Power supply, 1.8V to 5.5V.
