Original chip supplier IC EEPROM 1KBIT 3-WIRE 8SOIC AT93C46DN-SH-T

"AT93C46DN-SH-T" is a Serial One-Time Programmable Read-Only Memory (OTP-ROM) device. It offers 256 bits of storage capacity organized into 32 words of 8 bits each, accessed through a SPI-compatible serial interface. The device supports single or dual supply voltage operation between 2.7V to 5.5V and provides a high-speed clock rate up to ½ MHz. Its advanced security features include a user-programmable 64-bit unique identifier and software protection. This specific model comes in a small, surface-mount TDFN package, ideal for space-constrained applications like smart cards, SIM cards, set-top boxes, and other electronic devices where low-cost, non-volatile memory storage is required.
