Alternative Part Number

  • STM8S207CBT6 --: STM8 core 8-bit MCU in the same LQFP-48 package with comparable Flash and peripherals; a natural migration path from the ST7 family with strong availability.
  • AT89C51AC3-RLTUM --: 8051-compatible 8-bit MCU in LQFP-44 with similar I/O count and Flash size; widely stocked alternative for legacy 8-bit designs.
  • PIC18F45K22-I/PT --: 8-bit MCU in TQFP-44 with comparable memory and peripheral set; well-supported and readily available substitute for general-purpose control applications.
  • STM8S208RBT6 --: STM8 core MCU in same 44-pin LQFP package with comparable Flash and peripherals; ST's recommended migration path from ST7 family.
  • STM8S207RBT6 --: Pin-compatible STM8S series MCU in LQFP44 with similar memory and I/O count, suitable drop-in replacement after firmware port.
  • ATmega32A-AU --: Widely available 8-bit MCU in 44-pin TQFP with comparable Flash, RAM and peripherals; requires firmware rewrite but offers long-term supply security.
  • MC9S08DZ60MLH --: 8-bit S08 MCU in LQFP64 with similar Flash, RAM, and peripheral set; widely available alternative from another vendor.
  • PIC18F8722-I/PT --: 8-bit MCU in TQFP64 with comparable memory and I/O; a feasible cross-vendor replacement after pin and firmware adaptation.
