ON Semiconductor CAT1161WI-28-GT3 EEPROM

The CAT1161WI-28-GT3 is a high-performance, 16-Kb serial electrically erasable PROM (EEPROM) memory component from ON Semiconductor, a leader in energy-efficient innovations. This EEPROM device is designed to provide a robust and reliable non-volatile memory solution for a wide range of applications, from industrial and automotive systems to consumer electronics and smart devices.

Operating on a single supply voltage ranging from 2.5V to 6.0V, the CAT1161WI-28-GT3 offers a versatile power range to accommodate various system requirements. The device features a 16,384-bit serial EEPROM, organized as 2048 words of 8 bits each, which allows for efficient data storage and management within a compact footprint.

One of the key features of this EEPROM is its I²C serial interface, which supports standard (100 kHz), fast (400 kHz), and fast-plus (1 MHz) I²C protocol. This ensures high-speed data transfer and compatibility with a wide array of microcontrollers and processors. The CAT1161WI-28-GT3 also incorporates a hardware write protection pin (WP), which provides an additional layer of security by preventing accidental data alteration during operation.

The endurance of the CAT1161WI-28-GT3 is impressive, with the capability to withstand over one million write cycles and a data retention period of over 100 years. These characteristics make it an ideal choice for applications requiring frequent data updates and long-term data preservation.

ON Semiconductor has integrated several safety features into the CAT1161WI-28-GT3, including a built-in error correction code (ECC) mechanism that ensures data integrity by detecting and correcting single-bit errors. Additionally, the device automatically times out during write operations, preventing data corruption in the event of power interruptions or system malfunctions.

The CAT1161WI-28-GT3 comes in a compact 8-lead SOIC package, making it suitable for space-constrained applications. Its industrial temperature range of -40°C to +85°C guarantees stable operation under harsh environmental conditions, further extending its applicability across various market segments.

In summary, the CAT1161WI-28-GT3 from ON Semiconductor is a highly reliable and versatile EEPROM solution that combines performance, durability, and security features to meet the demands of modern electronic systems.
