Application Scenarios & Design Considerations

8-BIT MCU WITH SINGLE VOLTAGE FLASH MEMORY, DATA EEPROM, ADC, TIMERS, SPI, DALI (DATA BRIEFING)

Alternative Part Number

  • PIC16F1824-I/P --: 8-bit flash MCU with comparable core speed, memory and peripheral set; widely available and pin-compatible in many ST7FLITE25F2B6 socket designs after minor firmware porting.
  • ATMEGA48PA-PU --: Low-power 8-bit AVR MCU with similar flash/SRAM/EEPROM size and I/O count; strong second-source option for designs migrating away from ST7 family.
  • MSP430G2553IN20 --: Ultra-low-power 16-bit MCU with comparable on-chip flash and peripherals; suitable functional replacement where low power consumption is important.
  • ATtiny84A-PU --: Low-cost 8-bit AVR MCU with similar I/O and flash size, suitable drop-in functional replacement for simple control tasks.
  • MC9S08QG8CDTE --: 8-bit S08 core MCU with comparable memory and peripherals, good alternative when ST7 supply is constrained.
