AT93C46D-PU

Microchip Tech · EEPROM · PDIP-8

AT93C46D-PU from Microchip Tech, in a PDIP-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; the device is selected when CS is high, and DI is ignored and DO stays high-impedance while CS is low.
2 SK input Serial Data Clock; DI is latched on its rising edge and DO is clocked out on its rising edge.
3 DI input Serial Data Input; receives instructions, addresses and data, latched on the rising edge of SK.
4 DO tri_state Serial Data Output; shifts out read data after the rising edge of SK and outputs the Ready/Busy status after a write or erase when CS is brought high, otherwise high-impedance.
5 GND power_in Ground reference for the power supply; connect to system ground.
6 ORG input Internal Organization select; tied to VCC selects x16 (64 x 16), tied to GND selects x8 (128 x 8), and leaving it unconnected selects x16 via the internal 1 MΩ pull-up.
7 NC unconnected No Connect; not internally connected on this package.
8 VCC power_in Device power supply; operation at invalid VCC voltages may produce spurious results and should not be attempted (operating range 1.8 V to 5.5 V).
