47L04-I

Microchip Tech · Pre-ordered MCUs · SOIC-8

47L04-I 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 VCAP passive Capacitor input connected to the internal power bus; connect a CVCAP capacitor for Auto-Store, or tie to VCC (with Auto-Store disabled via ASE bit = 0) if no capacitor is used.
2 A1 input Chip address select input compared with client address Chip Select bits for up to four devices on one bus; internally pulled down to VSS if left unconnected.
3 A2 input Chip address select input compared with client address Chip Select bits for up to four devices on one bus; internally pulled down to VSS if left unconnected.
4 VSS power_in Ground.
5 SDA bidirectional Open-drain serial data pin for addresses and data, requiring a pull-up resistor to VCC (typical 10 kΩ for 100 kHz, 2 kΩ for 400 kHz and 1 MHz).
6 SCL input Serial clock input used to synchronize data transfer to and from the device.
7 HS input Hardware Store/Event Detect input that initiates a Hardware Store when driven high for THSPW time and sets the EVENT bit; internally pulled down to VSS if left unconnected.
8 VCC power_in Power supply; 2.7V-3.6V range for the 47L04.
