Single-chip system integrates non-volatile SRAM

The PSoC® NV family integrates the flexibility of the Programmable System-on-Chip (PSoC) architecture with nonvolatile nvSRAM technology. This provides a flexible platform for designing non-volatile systems that require unlimited read, write and recall endurance - such as data logging.

PSoC devices integrate configurable analogue and digital circuits, controlled by an on-chip microcontroller. This provides the capability to quickly revise designs and cut component count. The PSoC NV family, in particular, provides this advantage for applications that require continuous data logging from analogue and digital inputs. PSoC NV devices feature a powerful analogue front-end that can sample up to eight inputs and simultaneously store sample data in the embedded nvSRAM.

Operation accesses are directed to an SRAM array and automatically secured into a nonvolatile quantum-trap cell. This data can be recalled on power-up, protecting the system against power failure. The data-logging capabilities of the PSoC NV family enable field diagnostics and failure-mode analysis, helping to identify system problems and reduce system downtime.

The devices offer 20-year data retention and can perform a host of functions such as voltage monitoring, voltage sequencing, thermal management, on-board diagnostics, power management, fan control, industrial data logging, and sequence-of-events monitoring.
