256k nvSRAMs sampled for extended temperature ranges
Non-volatile memory products specialist Anvo-Systems Dresden, has provided samples of the ANV32C81ASE66nvSRAM (non-volatile SRAM) for an extended temperature range of -40 to 105°C and the ANV32C81ASA66nvSRAM even for -40 to 125°C.
Both serial SPI nvSRAMs feature a storage capacity of 256kb and are internally organised as 32k words of 8bits. Each SRAM memory cell integrates a SONOS flash storage element. In the event of an unforeseeable operating voltage drop below a defined value or via a software command, the SONOS technology enables non-volatile storage of all data.
Furthermore, the devices feature high clock rates and unlimited read and write endurance comparable to standard SRAMs. Special security functions, such as Block Write Protection, Write Disable Instruction, Secure READ and Secure WRITE, and reading of the last written address, ensure a high degree of reliability.
The clock rate of the non-volatile memory devices is 66MHz. There is support for SPI Modes 0 and 3. The integrated Power Down functionality (hibernate mode) ensures a low system power consumption.
The ANV32C81ASE66 and ANV32C81ASA66both can be operated with 3.0-3.6V and are delivered in a compact 8 Pin 150 mil SOIC package. The nvSRAMsare suitable for various applications, like industrial automation, robotics, servers, measurement technology, medical devices, building automation, smart metering systems, and for all applications demanding extended temperature ranges.
