STM65xx Smart Reset ICs

STMicroelectronics' dual pushbutton Smart Reset IC for manual reset applications

Image of STMicroelectronics' STM65xx Smart Reset™ ICsSTMicroelectronics' STM65xx family of Smart Resets™ consists of low power microprocessor reset circuits designed to provide an extended input delay period on single or dual Smart Reset inputs. A reset is asserted when valid Smart Reset input conditions (combined push button press) and set up time delays are met, with the aim of ensuring a safe reset and eliminating the need for a dedicated reset button. In a typical application, the Smart Reset inputs are connected to the interrupt lines, to allow the control of both the interrupt and the hard reset function. A short push sends an interrupt to the micro, a push longer than the setup time causes a hard reset.

Features Applications
  • Two Smart Reset pushbutton inputs with adjustable delay
  • Programmable reset setup delay (up to 15s):
    • 2-state logic (STM6520)
    • 3-state logic (STM6513, STM6503, STM6504)
    • External capacitor (STM6505, STM6510, STM6522)
  • Low supply current (3 µA typical)
  • Factory-programmed thresholds to monitor Vcc (except STM6520 and STM6522)
  • Power On reset (except STM6520 and STM6522)
  • Single or dual reset outputs (push-pull or open drain)
  • Fixed or programmable reset pulse duration (except STM6520)
  • TDFN-8 package: 2 x 2 x 0.75 mm, 0.5 mm pitch
  • Operating temperature -40°C to 85°C
  • Any application with a manual reset
    • Portable (consumer, industrial, telecom, healthcare)
    • White goods
    • STBs
    • Alarm systems
    • GPS
    • Portable media players
    • Smartphones and PDAs
