Application Scenarios & Design Considerations

5V RANGE 8-BIT MCU WITH 8 TO 32K FLASH/ROM, 10-BIT ADC, 4 TIMERS, SPI, SCI INTERFACE

Alternative Part Number

  • STM8S103K3T6 --: STM8 core 8-bit MCU in the same LQFP32 package with comparable Flash, RAM, and peripherals; a natural migration path from the ST72F series with strong availability.
  • STM8S003K3T6 --: Pin-compatible LQFP32 STM8S value-line MCU with 8 KB Flash and similar I/O count; suitable for cost-sensitive designs replacing the ST72F324B.
  • AT89C51ED2-RLTUM --: 8051-compatible MCU in LQFP44 with comparable 8-bit architecture and Flash; a viable cross-vendor alternative when ST72F supply is constrained, though pinout differs.
  • STM8S207K6T6 --: STM8S series 8-bit MCU in the same LQFP32 package with comparable Flash and peripherals, a natural migration path from ST7.
  • STM8S105K6T6 --: Pin-compatible STM8S 8-bit MCU in LQFP32 with similar memory and I/O, widely used as an ST7 replacement.
  • AT89C51RB2-UL --: Widely available 8-bit 8051-compatible MCU in a similar package with comparable Flash and I/O, usable as a cross-vendor alternative when reworking firmware.
