25LC160DT-E

Microchip Tech · EEPROM · SOIC-8

25LC160DT-E 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	A low level selects the device and a high level deselects it and forces Standby mode, and a low-to-high transition on CS after a valid write sequence starts an internal write cycle.
2	SO	output	Data is shifted out on SO after the falling edge of the serial clock during a read cycle, and SO goes to the high-impedance state when the device is deselected.
3	WP	input	When WP is low and WPEN is high, writes to the nonvolatile bits in the STATUS register are disabled, and the WP function is blocked when WPEN is low.
4	VSS	power_in	Ground reference pin for the device.
5	SI	input	Serial data input that receives instructions, addresses and data, latched on the rising edge of the serial clock.
6	SCK	input	Serial clock that synchronizes communication, with SI latched on the rising edge and SO updated after the falling edge.
7	HOLD	input	Pulling HOLD low while SCK is low pauses serial communication without resetting the sequence, and it must be held high when not used.
8	VCC	power_in	Supply voltage pin; the 25LC160D is specified at 2.5-5.5V VCC.
