IC SRAM 16KBIT 150NS 24DIP
The DS1220Y-150+ is a non-volatile static RAM (NVSRAM) manufactured by Maxim Integrated. It combines the functionality of a static RAM with the non-volatile characteristics of an EEPROM, offering data retention even when power is removed.
Here are some key features of the DS1220Y-150+:
1. Density and Organization: The DS1220Y-150+ has a density of 256 kilobits (32 kilobytes) and is organized as 8,192 words by 16 bits. Each word can be individually read from or written to.
2. Non-Volatile Storage: The DS1220Y-150+ utilizes a built-in lithium energy source to maintain data integrity in the absence of power. It allows for data retention for an extended period, typically over 10 years.
3. Byte-Wide Write Capability: The device allows for byte-wide write operations, providing flexibility in modifying specific portions of the memory.
4. High-Speed Access: The DS1220Y-150+ offers fast access times, enabling efficient read and write operations. It has a maximum access time of 150 nanoseconds.
5. Parallel Interface: It features a parallel interface that allows for straightforward interfacing with a microcontroller or other digital systems.
6. Industrial Temperature Range: The DS1220Y-150+ is designed to operate reliably across an industrial temperature range of -40°C to +85°C.
7. DIP Package: The "+ " in the part number indicates the package type, which is a 28-pin dual in-line package (DIP). This package type is commonly used for through-hole mounting and provides ease of use and compatibility with standard socket interfaces.
The DS1220Y-150+ NVSRAM is widely used in applications that require non-volatile memory storage combined with the speed and simplicity of SRAM. Some typical applications include data logging, real-time clocks, parameter storage, and configuration memory.
For detailed information on electrical characteristics, pin configurations, timing diagrams, and recommended operating conditions, I recommend referring to the datasheet and technical documentation provided by Maxim Integrated for the DS1220Y-150+ NVSRAM.
