Microchip Tech · Pre-ordered MCUs · PDIP-8
23K256-I 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 input: a low level selects the device, a high level deselects it and forces Standby mode, and SO goes high-impedance when deselected. |
| 2 | SO | tri_state | Serial Data Output: data is shifted out after the falling edge of the serial clock, and it goes high-impedance when CS is high or HOLD is low. |
| 3 | NC | unconnected | No connection; shown as NC on the package diagram and not listed in the pin function table. |
| 4 | VSS | power_in | Ground. |
| 5 | SI | input | Serial Data Input: receives instructions, addresses and data, latched on the rising edge of the serial clock. |
| 6 | SCK | input | Serial Clock input: synchronizes communication, latching SI on the rising edge and updating SO after the falling edge, with a maximum clock of 20 MHz. |
| 7 | HOLD | input | Hold input: pulled low (while SCK is low) to pause serial communication without resetting the sequence, and it must be held high when not in use. |
| 8 | VCC | power_in | Supply voltage: 2.7V to 3.6V for the 23K256, with an absolute maximum of 4.5V. |
