Application Scenarios & Design Considerations

8-BIT MCU WITH SINGLE VOLTAGE FLASH MEMORY, DATA EEPROM, ADC, 5 TIMERS, SPI

Alternative Part Number

  • PIC16F1823-I/P --: 8-bit Flash MCU with comparable pin count and peripherals; widely available and well documented as a functional substitute in many ST7FLIT19 designs.
  • ATtiny84A-PU --: Low-cost 8-bit AVR MCU with similar I/O and memory class; suitable drop-in functional replacement after firmware porting.
  • MSP430G2553IN20 --: Ultra-low-power 16-bit MCU with comparable package and peripheral set; strong alternative when low power and mixed-signal features are required.
