In the event of power failure, the nvSRAM automatically saves a copy of the data, protecting it for over 20 years
The 256 kb STK14C88C and 1 Mb STK14CA8C nvSRAMs are qualified in 32 pins 300 mil dual-in-line ceramic packages for MIL-PRF-38535 QML-Q specifications (-55°C to 125°C) and industrial standards (-40°C to 85°C). Both 5 V and 3 V versions support boot code, data logging and calibration data storage for aerospace, communications and navigation systems, in addition to industrial furnaces and railroad control systems.
The incorporation of nvSRAM technology combines high-performance SRAM with best-in-class SONOS non-volatile technology. Under normal operating conditions, nvSRAM acts similarly to a conventional asynchronous SRAM. In the event of a power failure, a nvSRAM automatically saves a copy of the SRAM data into non-volatile memory, where the data is protected for over 20 years.
“The new generation of nvSRAMs extends Infineon’s leadership in charge trap memories,” said Helmut Puchner, VP Fellow of Aerospace and Defense, at Infineon Technologies LLC. “These QML-Q and high-reliability, industrial-qualified devices in our expanded nvSRAM family demonstrate our commitment to deliver solutions for harsh operating environments that require high performance, high-reliability memories.”
The 256 kb STK14C88C and 1 Mb STK14CA8C nvSRAMs can be ordered now from Infineon Technologies.
