Memory
CG7902AAT is a type of non-volatile battery-backed SRAM memory module, created by a company called Princeton Technology Corporation. The module is most often used in non-standard sized systems, like the automotive instrumentation and industrial control markets. It offers a standard no-latency memory addressing scheme, meaning that all non-volatile reads and writes take place without any wait time.
The module is composed of up to 4 Kilobit SRAM modules in a standard DIMM package, utilizing a single 5V power supply. The SRAMs themselves are organized into two 16-bit words per memory address, for a maximum of 512 addressable memory locations. It has an asynchronous read-write DMA interface, so that reads and writes are independent of the processor. This is ideal for applications that require frequent memory access, such as for monitoring or logging.
The first use of the CG7902AAT was in automotive instrumentation, where it found a home in speedometers, tachometers, and other gauges. Its no-latency memory addressing scheme was particularly useful in these applications, allowing for faster refresh cycles and a more responsive user experience. Its use in industrial control applications also lends itself to its non-volatile nature. It can be used in systems where its frequently powered-off or restarted, ensuring no loses due to power outages or crashes.
The most common use of this SRAM module is in non-standard sized systems, such as ATMs or gaming machines. Its size and low power requirements make it an ideal choice for these applications, which often have limited space to dedicate to memory modules. It offers a good balance between size and performance in these types of applications.
In summary, the CG7902AAT is a non-volatile battery-backed SRAM memory module, most often used in non-standard sized systems, like the automotive instrumentation and industrial control markets. It offers a standard no-latency memory addressing scheme, and an asynchronous read-write DMA interface, making it ideal for applications that require frequent memory access. Its size and low power requirements also make it a good choice for non-standard sized systems, where space and power are at a premium.
