Application Scenarios & Design Considerations

LOW SPEED USB 8-BIT MCU WITH 3 ENDPOINTS, FLASH OR ROM MEMORY, LVD, WDG, 10-BIT ADC, 2 TIMERS, SCI, SPI

Alternative Part Number

  • STM8S003F3P6 --: Pin-compatible 8-bit MCU from ST's STM8 family with similar Flash/RAM and peripherals; a common drop-in upgrade path when the ST7 is unavailable.
  • PIC16F628A-I/P --: Widely available 8-bit MCU with comparable I/O count, timers, and Flash size; a practical cross-vendor substitute for legacy ST7 designs.
  • AT89C4051-24PU --: Low-cost 8051-core 8-bit MCU with similar pin count and memory footprint, suitable as a functional replacement in simple control applications.
  • PIC16F1824-I/ST --: Comparable 8-bit MCU in TSSOP20 with similar I/O count, Flash, and integrated peripherals; requires firmware port but is a strong functional alternative.
  • ATtiny84A-SSU --: Small 8-bit MCU in SOIC-14 with similar low pin count and peripheral set; suitable for cost-sensitive designs needing a functional equivalent with firmware changes.
