Description

The SFXG33PR501 is an electronic component model belonging to the product category of IC Chips. It is a combination of a 64 Kbit nonvolatile static random access memory (nvSRAM) and a full-featured Real Time Clock (RTC) integrated in a monolithic integrated circuit with a serial SPI interface. The memory is organized as 8 K words of 8 bits each. The SFXG33PR501 utilizes the QuantumTrap technology, making it the world's most reliable nonvolatile memory. It provides infinite read and write cycles, while the QuantumTrap cells ensure highly reliable nonvolatile storage of data.
