DS1245Y-85

Memory

The DS1245Y-85 is a non-volatile semiconductor memory that is characterized by its use of static RAM (or SRAM) technology. The device uses a multiplexer to switch between static memory and static Flash memory, allowing the device to store and instantly recall data without a power source. It is a versatile storage solution for any electronic application that requires data retention capabilities, such as consumer electronics, industrial instrumentation, automotive, medical, and consumer applications.

Features

The DS1245Y-85 provides two flash sector data storage areas with a total memory capacity of 85KB. The device is available in a number of standard speed grades, ranging from 15ns to 90ns. It features Parallel and Serial I/O modes for fast data transfers. The device includes power-saving circuitry, allowing it to operate with a low standby current consumption of 25µA. Also, the device is available in three different packages: 8-pin, 14-pin, and 20-pin.

Application Fields

The DS1245Y-85 is ideally suited for applications that require large data storage and fast memory access. It can be used in a wide range of applications, such as consumer electronics, industrial instrumentation, automotive, medical and consumer applications. This device can also be used to store and retrieve large data sets, such as in digital audio and video recorders, data loggers, and other data-intensive applications.

Working Principle

The DS1245Y-85 works as an electronic storage device. When power is applied to the device, static memory and static flash memory cells are connected through a multiplexer to allow for data storage. When a write signal is received, the static RAM is used to temporarily store the incoming data until it is permanently stored in the static flash memory. When a read signal is received, the multiplexer switches the static RAM out of the circuit and the static flash memory is used to access the previously stored data. As the device requires no persistent power supply to maintain the stored data, the device is ideal for battery-powered systems where data retention is essential.

Conclusion

The DS1245Y-85 is a versatile and powerful non-volatile semiconductor memory which offers both static RAM and static Flash memory, allowing for superior data storage and instant data recall. With features such as low power consumption, multiple I/O modes and various speed grades, this device is suitable for a variety of applications, including consumer electronics, industrial instrumentation, automotive, medical and consumer applications. Its efficient working principle makes it ideal for battery-powered systems, ensuring the device can consistently retain data even when power is absent.
