93LC86-I

Microchip Tech · EEPROM · SOIC-8

93LC86-I 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 into Standby mode, and CS must be low for at least 250 ns (TCSL) between consecutive instructions.
2 CLK input Serial Clock that synchronizes communication, clocking opcode, address and data bits in and data bits out on the positive edge, and is a don't-care when CS is low.
3 DI input Serial Data Input used to clock in the Start bit, opcode, address and data synchronously with CLK.
4 DO tri_state Serial Data Output that outputs read data synchronously with CLK and gives Ready/Busy status during erase/write while CS is high, and is high-Z otherwise.
5 VSS power_in Ground.
6 ORG input Memory organization select: tied to VCC selects x16, tied to VSS selects x8, and an internal pull-up selects x16 when left unconnected.
7 PE input Program Enable: floated or tied to VCC allows programming, tied to VSS inhibits programming, and an internal pull-up enables programming when left floating.
8 VCC power_in Power supply, +2.5V to +6.0V operating range (7.0V absolute maximum).
