Application Scenarios & Design Considerations

8-bit microcontroller with single voltage Flash memory, data EEPROM, ADC, Timers, SPI

Alternative Part Number

  • PIC16F1824-I/P --: 8-bit flash MCU with comparable pin count and peripherals; widely available and well documented as a functional substitute in many ST7FLITE25 designs.
  • ATMEGA48PA-PU --: Low-power 8-bit AVR MCU with similar flash, RAM and I/O resources; a common cross-vendor replacement when firmware is ported.
  • STM8S003F3P6 --: ST's own 8-bit MCU family positioned as successor to ST7; similar core architecture and peripheral set, easing migration.
  • MC9S08QG8CDTE --: 8-bit S08 MCU with similar flash size, integrated ADC and timers; suitable functional replacement when porting firmware.
  • PIC16F628A-I/P --: Widely available 8-bit flash microcontroller in DIP-20 with comparable I/O, timers, and peripherals; strong second-source option for ST7FLITE25 designs.
  • ATtiny2313A-PU --: Low-cost 8-bit AVR microcontroller in DIP-20 offering similar flash, RAM, timers, and USART resources for small control applications.
