Microchip Technology's 93LC46C-E/ST EEPROM

The 93LC46C-E/ST is a high-quality, electrically erasable programmable read-only memory (EEPROM) device from the renowned manufacturer, Microchip Technology. This device is part of the 93XX series EEPROM, which is designed for data storage in a wide range of applications, including industrial, automotive, and consumer electronics.

The 93LC46C-E/ST is a 1Kb (128 x 8 or 64 x 16) serial EEPROM, featuring a user-selectable internal organization of either 128 8-bit words or 64 16-bit words. This flexibility allows designers to choose the best data storage format for their specific application requirements. The device operates at a voltage range of 2.5V to 5.5V, making it suitable for low-power operations and compatible with most microcontroller logic levels.

One of the key features of this EEPROM is its self-timed erase and write cycles, which eliminate the need for external timers and simplify the interfacing process. The typical write cycle time is 5 ms, allowing for efficient data management and fast update times. Additionally, it supports a bidirectional data transfer protocol, which provides a simple and convenient way to read and write data through a serial interface.

The 93LC46C-E/ST comes in a compact 8-pin TSSOP (Thin Shrink Small Outline Package) package, which is ideal for space-constrained applications. It also includes a write-protect pin that ensures data integrity by preventing accidental data overwrites and erasure.

For enhanced data security, the device features a programmable write-protection with varying levels of protection, including full array, half array, or quarter array protection. This allows users to secure critical data while still being able to update other sections of the memory as needed.

Overall, the 93LC46C-E/ST EEPROM from Microchip Technology is an excellent choice for designers looking for a reliable and versatile non-volatile memory solution. Its robust feature set and ease of integration make it suitable for a multitude of applications that require data storage and retrieval without the need for a constant power supply.
