93LC46-I/SN General Description

The 93LC46-I/SN is a serial electrically erasable programmable read-only memory (EEPROM) chip manufactured by Microchip Technology. It has a storage capacity of 1 Kbits organized into 128 bytes of memory. The chip operates at a voltage range of 2.5V to 5.5V and has a maximum clock frequency of 2 MHz.The 93LC46-I/SN features a 3-wire serial interface with a dedicated chip select (CS), data in/out (DI/DO), and clock (SCK) pins for communication with a microcontroller or other devices. This interface allows for easy integration into various embedded systems and applications.The EEPROM chip also includes built-in protection features such as write protection and partial write protection to prevent data corruption or loss. It has a maximum endurance of 1 million erase/write cycles, ensuring reliable and long-lasting performance.The 93LC46-I/SN comes in a small 8-pin SOIC package, making it suitable for space-constrained designs. It operates over a wide temperature range from -40°C to 125°C, making it suitable for industrial and automotive applications.
