93LC86CT-I

Microchip Tech · EEPROM · SOIC-8

93LC86CT-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 A high level selects the device and a low level deselects it and forces Standby mode; CS must be low for 250 ns minimum (TCSL) between consecutive instructions.
2 CLK input Serial Clock synchronizes communication with the master, with opcodes, address and data clocked in and data clocked out on the positive edge of CLK.
3 DI input Serial Data Input clocks in the Start bit, opcode, address and data synchronously with CLK.
4 DO tri_state Serial Data Output outputs read data synchronously with CLK (TPD after the positive CLK edge) and provides Ready/Busy status during erase/write, going High-Z if CS is held low through the cycle.
5 VSS power_in Ground reference for the device.
6 ORG input Selects x16 organization when tied to VCC or logic high and x8 when tied to VSS or logic low; it must be tied to a valid logic level (93XX86C only).
7 PE input Program Enable: tied to VCC allows programming and tied to VSS inhibits programming; it cannot be floated (93XX86C only).
8 VCC power_in Power supply; the 93LC86C operates from 2.5 V to 5.5 V.
