Microchip Introduces New Serial SRAM and Serial NVSRAM Devices

Microchip Technology serial SRAM and serial NVSRAM

Microchip Technology announced six new devices. Four of the devices are the 23A1024, 23LC1024, 23A512 and 23LC512 serial SRAM. The other two devices are the 23LCV512 and 23LCV1024 serial NVSRAM. Prices start at $1.16 each for the four volatile devices in 10,000-unit quantities. The 23A1024 and 23LC1024 are available now for sampling and volume production. The 23A512 and 23LC512 will be available for sampling and volume production in October of this year. The two non-volatile, unlimited-endurance RAM are priced at $1.32 each in 10,000-unit quantities. Sampling and volume production of the non-volatile devices will begin in October.

Microchip’s new serial SRAM devices feature the industry’s largest densities and speeds. They are also the first devices with 5V operation, which remains prevalent in automotive and industrial applications. Speeds of up to 80 Mbps are achieved via the quad-SPI, or SQI, protocol, providing the zero write-cycle times with near instantaneous data movement needed for offloading graphics, data buffering, data logging, displays, math, audio, video and other data-intensive functions.

The 23LCV512 and 23LCV1024 feature fast dual-SPI (SDI) throughput of 40 Mbps and low active and sleep currents. The serial NVSRAM devices include high-speed operation without the high pin counts of parallel NVSRAM. They also offer comparable power consumption to FRAM, but at a fraction of the price. The serial NVSRAM devices are ideal for applications such as meters, black boxes and other data recorders, which require unlimited endurance or instantaneous writes along with non-volatile storage.

All six devices from the serial SRAM family are available in 8-pin SOIC, TSSOP and PDIP packages. The density options are 512 Kbits and 1 Mbit.
