Microchip Expands Serial SRAMs With Industry’s Largest and Fastest Devices at 1 Mbit Densities and 80 Mbps Speeds; First at 5V Operation
Two additional family members—the 23LCV512 and 23LCV1024—offer the industry’s most cost-effective options for non-volatile, unlimited-endurance RAM, via battery backup. In fact, with their fast dual-SPI (SDI) throughput of 40 Mbps and low active and sleep currents, these serial NVSRAM devices feature high-speed operation without the high pin counts of parallel NVSRAM, and comparable power consumption to FRAM, all at a fraction of the price. This is beneficial for applications such as meters, black boxes and other data recorders, which require unlimited endurance or instantaneous writes along with non-volatile storage.
“Most embedded applications need more RAM at some point during their design. These new 1 Mbit SRAMs enable designers to fill that gap at a much lower cost than moving to a larger microcontroller or processor, and with lower power consumption, pin counts and cost than parallel SRAM,” said Randy Drwinga, vice president of Microchip’s Memory Products Division. “For applications requiring non-volatile RAM, we’ve also added our first two devices with battery backup, which are significantly lower cost than any other type of non-volatile RAM.”
“The EEPROM market has completely moved to serial interfaces, and the Flash market is rapidly making this transition, due to the higher cost, board space and power consumption of parallel devices. We expect SRAM to follow this trend, and Microchip’s serial SRAM portfolio offers compelling options to the embedded market,” Drwinga added.
