ON Semiconductor's CAT28C17AW-20 EEPROM

The CAT28C17AW-20 is a high-performance 16-Kbit Parallel Electrically Erasable Programmable Read-Only Memory (EEPROM) component designed and manufactured by ON Semiconductor. This versatile memory chip offers a robust storage solution for a wide array of applications that require data retention even when power is removed. It is an ideal choice for system configuration, hardware calibration data storage, and product identification, among other uses.

Featuring a 16,384-bit (2K x 8) non-volatile memory array, the CAT28C17AW-20 ensures data integrity and retention for a minimum of 100 years. The device operates over a wide voltage range of 4.5V to 5.5V, making it compatible with many standard microcontrollers and digital systems. With an access time of 200 nanoseconds, it provides quick data retrieval, enhancing overall system performance.

The EEPROM is organized as 256 pages of 64 bytes each, allowing for efficient page-write operations. The CAT28C17AW-20 also supports a byte-write capability, providing flexibility for applications that require frequent updates of small data elements. The page-write feature significantly improves the write performance by allowing multiple bytes to be written in a single operation.

One of the key features of this device is its hardware and software write protection. The CAT28C17AW-20 includes a write enable (WE) pin and a write protect (WP) pin, which prevent accidental data alteration. Additionally, the chip supports a software data protection scheme that requires a specific sequence of commands to be issued before any write operation can be executed, further safeguarding the stored data.

Designed for reliability, the CAT28C17AW-20 is packaged in a 32-pin plastic DIP (Dual In-line Package), ensuring easy integration into various circuit board layouts. This packaging also provides durability and a long operational lifespan, which is crucial for industrial and commercial applications that demand consistent performance over extended periods.

In summary, the CAT28C17AW-20 from ON Semiconductor is a dependable and flexible EEPROM solution that offers high-speed data access, low-power consumption, and robust data protection features. Its durability and ease of integration make it an excellent choice for designers and engineers looking for a reliable non-volatile memory component.
