Anvo-Systems’ product line, now being stocked by Mouser Electronics, include both parallel and serial non-volatile SRAM (nvSRAM) solutions. The nvSRAMs combine two proven technologies (CMOS-SRAM and SONOS non-volatile memory) into a new technology that is said to be greater than the sum of its parts in that these products combine properties like speed, reliability, and energy efficiency. Based on standard parallel or serial SPI SRAM pinning, with unrestricted internal SRAM functionality, both fast reads and writes can be executed with the same high speed.
The product range includes the ANV22AA8x parallel 2 Mbit nvSRAMs devices with a non-volatile SONOS storage element included with each memory cell. The devices feature unlimited read/write endurance and fast performance with a 25-nanosecond access time. and unlimited RECALL cycles. The ANV32A62x devices are 64 Kbit serial SRAMs featuring a two-wire serial interface (I²C) and a bi-directional data transfer protocol. The low-power ANV32A62 devices are accessed by a two-wire bus, which can support up to four cascadable devices.
Anvo-Systems’ ANV32E61x and ANV32AA1x serial nvSRAM products feature an SPI interface to ensure reliable storage of data in the event of a sudden power drop or when initiated by a command. The ANV32AA1x series includes the standard nvSRAM double memory architecture of two 1 Mbit arrays, and provides fast access and cycle times and unlimited read and write endurance. To ensure high data accuracy, the devices feature dedicated safety features, such as flash memory that stores the data non-volatile, independent from external power supply. The ANVE32E61x series features 64 Kbit serial SRAMs with unlimited RECALL cycles, page and block rollover options, and hibernate mode for low standby current. Each SRAM features a non-volatile SONOS storage element, with automatic data transfer in the event of power loss or any brown out situation.
