Microchip Tech · Pre-ordered Chips · SOIC-8

93LC56 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: a high level selects the device and a low level deselects it and forces Standby mode, and CS must be low for 250 ns minimum (TCSL) between consecutive instructions.
2	CLK	input	Serial Data Clock that synchronizes communication with the master, clocking opcode, address and data in on the positive edge, with a clock frequency of up to 2 MHz at VCC ≥ 4.5V and 1 MHz otherwise.
3	DI	input	Serial Data Input used to clock in the Start bit, opcode, address and data synchronously with the CLK input.
4	DO	tri_state	Serial Data Output that outputs data synchronously with CLK (TPD max 400 ns) in Read mode, gives Ready/Busy status during erase/write, is High-Z otherwise, and needs a pull-up resistor to read the Ready signal if status is checked after the cycle.
5	VSS	power_in	Ground.
6	ORG	input	Memory Configuration: tied to VCC selects x16 organization and tied to VSS selects x8, and it may be floated only for clock speeds of 1 MHz or less in x16 organization.
7	NU	unconnected	Not Utilized.
8	VCC	power_in	Power supply, with DC characteristics specified for VCC = 2.5V to 5.5V and an absolute maximum of 6.5V.
