Microchip Technology's 93LC46/SN EEPROM

The 93LC46/SN is a high-quality, electrically erasable programmable read-only memory (EEPROM) component manufactured by Microchip Technology. This device is designed for data storage applications where reliable and efficient non-volatile memory is crucial. The 93LC46/SN is part of Microchip's extensive EEPROM product line, which is renowned for its stability and endurance.

This particular EEPROM offers a storage capacity of 1 Kbit, organized as 64 x 16-bit with the 93LC46 variant, making it suitable for storing configuration settings, calibration data, and small application parameters. Its serial interface ensures easy integration into a wide range of microcontroller-based systems, providing a simple and effective way to read and write data.

The 93LC46/SN operates over a voltage range of 2.5V to 5.5V, which allows for compatibility with both 3.3V and 5V logic levels, making it versatile for use in various system designs. It features a self-timed erase and write cycle with automatic erase-before-write capability, ensuring data integrity with minimal software overhead. The typical write cycle time is 5 ms, allowing for quick updates to stored data.

Additional features of the 93LC46/SN include its support for the industry-standard 3-wire serial communication protocol, which consists of Chip Select (CS), Serial Clock (SK), and Serial Data (DI/DO) lines. This EEPROM also provides a sequential read operation, which streamlines the process of accessing multiple data bytes in succession.

For enhanced data protection, the 93LC46/SN includes write protection mechanisms such as a write enable latch and programmable write protect pins. These features prevent accidental data alteration and ensure the integrity of the stored information. The device is offered in an 8-pin SOIC (SN) package, which is suitable for surface-mount technology (SMT) and occupies minimal space on a printed circuit board (PCB).

With its robust design, reliable data retention of over 200 years, and the ability to withstand over 1 million erase/write cycles, the Microchip Technology 93LC46/SN EEPROM is an excellent choice for applications requiring a compact, non-volatile memory solution.
