AT88SC0204CA-SH-T 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 | NC | unconnected | No connect pin on the 8-lead SOIC/PDIP pinout. |
| 2 | NC | unconnected | No connect pin on the 8-lead SOIC/PDIP pinout. |
| 3 | NC | unconnected | No connect pin on the 8-lead SOIC/PDIP pinout. |
| 4 | GND | power_in | Ground pin. |
| 5 | SDA/IO | bidirectional | Open-drain bidirectional serial data pin that needs an external pull-up resistor to VCC, which sets the rise time and so the maximum read frequency. |
| 6 | SCL/CLK | input | Serial clock input. Synchronous data is clocked on the positive edge when writing and on the negative edge when reading. The asynchronous T=0 protocol uses it as the carrier frequency f, with 1 ETU = 372/f. |
| 7 | NC | unconnected | No connect pin on the 8-lead SOIC/PDIP pinout. |
| 8 | VCC | power_in | Positive supply input, 2.7V to 3.6V, supplied by the host. |
