CY7C1353S-100AXCT application field and working principle

CY7C1353S-100AXCT, categorized as Memory, is a synchronous SRAM chip manufactured by Cypress MicroSystems Inc. It is ideal for industrial applications requiring an associative memory function, such as robots, controllers, and medical equipment, because of its high-speed operation and low-power features.

The chip features organized memory spaces of 32, 36, 64 or 128 words with individual word length selection up to 32 bits. CY7C1353S-100AXCT is operated with a single clock cycle per word and provides low voltage operation at 3.3V/5V. It also offers access time of 10ns/20ns and fast write time of 15ns/25ns. Additional features include 8K refresh cycles and read/write organizations.

Working Principle

CY7C1353S-100AXCT contains two memory blocks divided into the write memory block and the read memory block. The write memory block is designed to write data to the chip, while the read memory block is designed to read data. Both memory blocks are organized as 32 words by 32 bits and 64 bits. The chip can be configured as single words, four words, eight words or sixteen words.

The chip operates in one clock cycle per word – write and read. It is also capable of bursting the data over multiple clock cycles. The chip has several selectable input pins to control the data flow, allowing it to support the configurable write and read protocol. The chip contains a burst control logic to manage the bursting data flow.

The chip also supports data pre-fetching and post-fetching. Data pre-fetching means the data is fetched from the memory block before it is requested. Data post-fetching means the data is fetched from the memory block after it is requested. The chip contains two separate logic circuits for data pre-fetching and data post-fetching.

The chip also supports the associative memory function. The associative memory function allows the user to search for specific data by providing a specific key. The associative memory function helps to reduce the memory usage and minimize data duplication.

CY7C1353S-100AXCT also supports various error correction coding (ECC) features for extra reliability. The ECC features include single error correction, double error detection and error correction (SERDC) code and on-chip ECC protection. The SERDC code is used to detect single bit errors in the data and the on-chip ECC protection is used to detect and correct multiple bit errors.

Conclusion

CY7C1353S-100AXCT is a SRAM chip manufactured by Cypress MicroSystems Inc. It is suitable for industrial applications requiring an associative memory function, such as robots, controllers, and medical equipment, due to its high-speed operation and low-power features. It can be configured as a single word, four words, eight words or sixteen words. It supports various features such as data pre-fetching, post-fetching and burst control. It also supports associative memory and error correction coding.
