EEPROM Memory IC: Microchip 25LC160AT-I/SN - A 16K SPI Bus Serial EEPROM Solution

In the realm of non-volatile memory, Serial EEPROMs play a pivotal role in storing critical data in embedded systems. The Microchip 25LC160AT-I/SN stands out as a reliable and efficient 16Kbit serial EEPROM component, leveraging the ubiquitous SPI Bus serial interface for straightforward communication with microcontrollers and processors.

This IC provides 2 Kbytes of byte-alterable memory, organized as 256 x 8 bits. Its key strength lies in its simple interfacing. The SPI-compatible bus supports clock frequencies up to 10 MHz, enabling high-speed data read and write operations, which is crucial for applications requiring frequent and fast access to configuration parameters or data logs. The device features hardware write protection via the WP (Write Protect) pin, safeguarding memory contents from unintended writes. Furthermore, it employs an advanced self-timed write cycle, which automatically handles the internal programming timing, simplifying software overhead. The block write protection can be set to protect none, quarter, half, or the entire array.

Housed in a space-saving 8-lead SOIC (SN) package, it is ideal for compact PCB designs. With an extensive voltage range from 2.5V to 5.5V and low power consumption, it is suited for a wide array of applications, including industrial controls, automotive systems, consumer electronics, and smart meters for storing calibration data, user settings, and event histories. Its high reliability and endurance of 1,000,000 erase/write cycles per sector and data retention of over 200 years make it a robust choice for long-term deployments.

ICGOODFIND: The Microchip 25LC160AT-I/SN is a quintessential SPI Serial EEPROM offering a perfect blend of simplicity, performance, and non-volatile reliability for modern electronic designs.
