Cypress MicroSystems announces programmable System-on-Chip (PSoC) devices for portable, flash-based applications, including remote sensors, handheld instruments, and portable consumer electronics. PSoC devices are high-performance, field-programmable, mixed-signal arrays for high-volume embedded-control functions. With a typical sleep current of 3 μA, with all power supervisory functions turned on, PSoC offers low system power consumption. PSoC's sleep-mode specification includes operation of all power supervisory functions, including power-on reset (POR), which ensures that the part only starts to operate when power is within operating limits; brown-out detection (BOD), which insures that the part shuts down safely when power is not within preset limits; low-voltage detection (LVD), which alerts the processor that power is failing; sleep timer, which wakes the part periodically to perform time-critical functions; and watchdog timer (WDT), which resets the processor if it is not properly executing code. PSoC CY8C26x family devices draw 3 μA in sleep mode with all power supervisory functions turned on, for a total power consumption of 10 μW.
