Cypress PSoC NV Configurable Mixed-signal Array

Cypress Semiconductor Corp. (NYSE:CY) recently announced the first device to integrate a non-volatile static random access memory (nvSRAM) and a programmable system on chip. The PSoC® NV family combines the flexible design capabilities of Cypress’s PSoC architecture with an infinite endurance nvSRAM in a single package. PSoC NV devices integrate configurable analog and digital circuits, controlled by an on-chip microcontroller, providing both enhanced design revision capability and component count savings. The secure-store data logging devices target the computing, networking, telecomm, automotive and industrial markets.

Cypress PSoC NV Family of Configurable Mixed-signal ArrayThe PSoC NV family is ideal for applications requiring continuous data logging from sensors, analog, and digital inputs. The devices have a powerful analog front-end that can simultaneously sample up to 8 inputs from sensors and analog sources and store the data in the embedded nvSRAM. Regular operation accesses are directed to an SRAM array and automatically secured into a non-volatile quantum trap cell in case of power failure. This data can be recalled on power up. The data logging capabilities of the PSoC NV family enables field diagnostics and failure mode analysis, helping customers identify problems quickly and reducing system downtime. The devices have a 20-year data retention capability and can perform a host of applications such as voltage monitoring, voltage sequencing, thermal management, on-board diagnostics, power management, fan control, industrial data logging, and sequence-of-events monitoring.
