The ZVP3310B is a monolithic integrated circuit (IC) designed and manufactured by Plessey. It is an analog memory device, specifically a Z-RAM, which is a type of non-volatile random access memory (NVRAM). The ZVP3310B is an 8-kilobit chip with an endurance of 2 million write cycles, a cycle time of 25 µs, and a data retention time of 10 years. It utilizes an NMOS process, is available in PDIP, SOIC, and leadless chip carriers, and has an operating temperature range of -40 to +125°C. The ZVP3310B can be used for applications such as data retention, data buffer, and non-volatile latch storage.
