AT88SC0204CA-SH-T

Microchip Tech · Security Verification / Encryption ICs · SOIC-8

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.
