Anvo-Systems Dresden GmbH, who specialise in non-volatile memory products have expanded their product portfolio with the 64Kb ANV32E61ASA66. A non-volatile SRAM (nvSRAM) with Serial Peripheral Interface (SPI). The memory device enables storage of all data in the event of an unforeseeable operating voltage drop increasing security of a modern industrial system. The non-volatile data retention of ten years ensures high system reliability.
The non-volatile SRAM is specified for the Automotive temperature range of -40°C to +125°C. The memory device is suitable for innovative applications demanding extended temperatures, like industrial automation, robotics, industrial IoT based systems, building automation, smart metering, and black boxes.
For the space-saving integration, the memory device is available in a compact, RoHS compliant 8 pin 150mil SOIC package.
The nvSRAM features a storage capacity of 64Kb and is internally organized as 8 k words of 8 bits. Each SRAM memory cell integrates a SONOS flash storage element. In the event of sudden operating voltage drop, the SONOS technology enables non-volatile storage of all data in the PowerStore operation. On power up, the data are automatically restored in the SRAM. The ANV32E61ASA66 features a clock rate of 66MHz and unlimited read & write endurance comparable to standard SRAMs. Special security functions, such as Block Write Protection, Secure READ and Secure WRITE, ensure a high degree of reliability.
The integrated power down functionality (Hibernate Mode) ensures low system power consumption in standby mode. The serial SPI nvSRAM can be operated with 3.0V to 3.6V.
