The CY62177EV30LL-55BAXI is a high-density nonvolatile static random-access memory (nvSRAM) that combines the fast random access of static RAM and the nonvolatile characteristics of EEPROM. This versatile device is a single chip solution for applications that require on-board data retention of RAM content. It is organized as 256K x 8 bits and is available in both 3.3V and 5V commercial versions.

The CY62177EV30LL-55BAXI offers a combination of high data retention, fast random access and low power consumption, making it an ideal solution for applications needing to retain data when power is removed. It eliminates the need for external EEPROM or a battery backup solution, reducing cost and board space. Its fast access time of 55ns makes the device suitable for applications that require fast, real-time data access, such as instrumentation and medical equipment.

The CY62177EV30LL-55BAXI can play an important role in counter applications and data logging, where on board data retention is needed. Its advanced architecture and design also eliminates the need for error correction code (ECC) circuitry, allowing for the full memory capacity to be used. The device is also compatible with most industry programmable logic devices for fast and easy connections.

The CY62177EV30LL-55BAXI utilizes an auto block write operation for fast and efficient writes of current memory contents. This operation writes entire blocks into the nvSRAM array in one operation, allowing for fast writes of the entire memory array and eliminating the need for busy waits. This feature allows for more design flexibility, as data can be easily transferred to the nvSRAM array without long wait times.

The CY62177EV30LL-55BAXI has a built-in power fail protection system that maintains data in the event of power failure. The device also has an integrated protection diode, reducing electrical noise and protecting against accidental power cycling and power surges. The nvSRAM also features a low power standby mode, reducing power consumption and extending battery life.

The CY62177EV30LL-55BAXI incorporates a patented write cycle enhancement architecture that increases the write endurance of the device. This feature improves data integrity by preventing data corruption due to multiple cell write cycles and program/erase cycles. The device also includes a power-on reset circuitry that ensures that all data is initialized or cleared at power-up.

The CY62177EV30LL-55BAXI is available in a 44-pin plastic SOIC, 44-lead PLCC and 44-pin TSOP packages, making it suitable for a variety of applications. It is available in industrial and automotive grade temperature ranges, allowing for reliable operation in harsh environments. It has an operating temperature range of -40°C to +85°C and is rated for up to +125°C, providing highly reliable operation.

The CY62177EV30LL-55BAXI is a high-density nonvolatile static random-access memory (nvSRAM) that offers a combination of fast random access, low power consumption and nonvolatile data retention. Its fast access time of 55ns make it suitable for applications needing real-time data access, such as instrumentation and medical equipment. Its patented write cycle enhancement architecture improves data integrity and its integrated power fail protection ensures that data is retained even during power failure. With it wide range of packages and operating temperature ranges, the CY62177EV30LL-55BAXI is an ideal solution for applications needing on-board data retention of RAM content.
