93AA56AT-I

Microchip Tech · EEPROM · SOT-23-6

93AA56AT-I from Microchip Tech, in a SOT-23-6. 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 DO output Data Out outputs read data synchronously with CLK (TPD after the positive CLK edge) and also indicates Ready/Busy status during erase/write when CS is brought high after TCSL.
2 VSS power_in Ground reference pin for the device.
3 DI input Data In clocks in the Start bit, opcode, address and data synchronously with the CLK input.
4 CLK input Serial Clock synchronizes communication; opcodes, address and data bits are clocked in on the positive edge of CLK, and CLK is a don't care while CS is low.
5 CS input Chip Select: high selects the device and low deselects it into Standby mode, with CS held low for 250 ns minimum (TCSL) between consecutive instructions.
6 VCC power_in Power supply pin; the 93AA56A is specified for 1.8 V to 5.5 V operation.
