Cypress Semiconductor has introduced a new 1 Mbit serial non-volatile static random access memory (nvSRAM) family and new 4 Mbit and 8 Mbit nvSRAMs with an integrated realtime clock (RTC).
Cypress’s nvSRAMs are manufactured on its S8 0,13 micron SONOS (silicon oxide nitride oxide silicon) embedded non-volatile memory technology, enabling high densities and improved access times and performance. nvSRAMs are ideal solutions for applications requiring absolute non-volatile data security such as RAID systems, industrial control and automation (eg, PLCs, motion control, motor drives and robotics), single board computers, POS terminals, eMetering, automotive, medical and data communication systems.
The serial nvSRAM family includes 1 Mb devices in multiple configurations with an industry-standard SPI interface. Available in small-footprint 8-pin DFN and 16-pin SOIC packages, the chips feature operating frequencies up to 40 MHz. They feature access times as low as 20 ns, infinite read, write and recall cycles, and up to 20 years of data retention. The new 4 Mb and 8 Mb devices integrate an RTC that enables time-stamping of critical data for backup and also features a programmable alarm function and watchdog timer.
Cypress’s nvSRAMs are RoHS-compliant and directly replace SRAM, battery-backed SRAM (BBSRAM) and EEPROM devices, offering fast non-volatile data storage without batteries. Data transfers from the SRAM to the device’s non-volatile elements take place automatically at power-down. On power-up, data is restored to the SRAM from the non-volatile memory. Both operations are also available under software control.
The 1 Mb serial nvSRAMs are available in a 128k x eight configuration. The CY14B101Q1 and CY14B101Q2 devices are available in an 8-pin DFN package. The CY14B101P serial device with RTC and the CY14B101Q3 are available in a
16-pin SOIC package. The 4 Mb nvSRAM with RTC comes in 512k x eight (CY14B104K) and 256k x 16 (CY14B104M) configurations. The 8 Mb nvSRAM with RTC comes in 1024k x eight (CY14B108K) and 512k x 16 (CY14B108M) configurations. The 4 Mb and 8 Mb devices are all available in 44-pin and 54-pin TSOP II packages.
