Sales Briefcase
  • STNRG devices are a part of the STNRG family of STMicroelectronics® digital devices designed for advanced power conversion applications.

    The STNRG improves the design of the successful STLUX™ family, now integrated in a wide range of LED driver architectures, to support industrial power conversion applications such as PFC+LLC, interleaved LC DC/DC, interleaved PFC for smart power supplies as well as the full bridge for pilot line drivers for electric vehicles.

    Key Features

    • Up to 6 programmable PWM generators (SMED - “State Machine Event Driven”)
      • 10 ns event detection and reaction
      • Max.1.3 ns PWM resolution
      • Single, coupled and two coupled operational modes
      • Up to 3 internal/external events per SMED
    • 4 analog comparators
      • 4 internal 4-bit references
      • Up to 4 external references
      • Less than 50 ns propagation time
      • Continuous comparison cycle
      • Configurable hysteresis voltage levels
    • ADCs (up to 8 channels)
      • 10-bit precision, with operational amplifier to extend resolution to 12-bit equivalent
      • Sequencer functionality
      • Input impedance: 1 MΩ
      • Configurable gain value: x1 and x4
    • Integrated microcontroller
      • Advanced STM8® core with Harvard architecture and 3-stage pipeline
      • Max. fCPU: 16 MHz
    • Memories
      • Flash and E2PROM with read while write (RWW) and error correction code (ECC)
      • Program memory: 32 Kbytes Flash; data retention 15 years at 85 °C after 10 kcycles at 25 °C
      • Data memory: 1 Kbyte true data E2PROM; data retention:15 years at 85 °C after 100 kcycles at 85 °C
      • RAM: 6 Kbytes
    • Clock management
      • Internal 96 MHz PLL
      • Low power oscillator circuit for external crystal resonator or direct clock input

    • Reset and supply management
      • Multiple low power modes (wait, slow, auto- wakeup, Halt) with user definable clock gating
      • Low consumption power-on and power- down reset
    • I/O
      • Multifunction bidirectional GPIO with highly robust design, immune against current injection
      • Fast digital input DIGIN, with configurable pull-up
    • Communication interfaces
      • UART asynchronous with SW flow control and bootloader support
      • I2C master/slave fast-slow speed rate
