Microchip Technology 93LC56B EEPROM
The 93LC56B is a high-quality Electrically Erasable Programmable Read-Only Memory (EEPROM) device from Microchip Technology, a leading provider of smart, connected, and secure embedded control solutions. This particular EEPROM is part of Microchip's renowned 93XX series, which is designed for storing data that must be preserved during power-down events, such as device configuration or calibration data.
The 93LC56B offers a storage capacity of 2 Kbits with a data word length of 8 or 16 bits selectable via external pins. This flexibility allows designers to choose the appropriate word size for their application, optimizing memory usage. The memory is organized as either 128 x 16-bit words or 256 x 8-bit words, providing versatility for various data storage requirements.
With its wide operating voltage range of 2.5V to 5.5V, the 93LC56B can be used in a multitude of environments and is particularly suited for low-power applications. Its low power consumption extends battery life in portable devices, making it an ideal choice for mobile and wearable technology.
One of the key features of the 93LC56B EEPROM is its self-timed erase and write cycles, which include auto-erase before writing to the memory array. This ensures data integrity and simplifies the programming process. Additionally, the device supports a write cycle time of only 5 ms, enabling quick updates to stored data.
The device communicates via a simple, three-wire serial interface that is SPI compatible, allowing for easy integration into existing designs. It also supports a bus protocol that does not require device polling, which simplifies software development and reduces overhead.
To protect valuable data, the 93LC56B includes hardware write-protect features. The device is available in several packages, including PDIP, SOIC, and TSSOP, providing flexibility for various PCB layouts and space requirements.
Overall, the Microchip Technology 93LC56B EEPROM is a reliable and versatile choice for designers who require a compact, non-volatile memory solution with robust features and a proven track record in the industry.
