Application Scenarios & Design Considerations

8-Bit Remote Type MCU

Alternative Part Number

  • PIC12F509-I/P --: 8-bit flash microcontroller in a similar low-pin-count package with comparable I/O and OTP/flash program memory, widely available and easy to port simple control firmware to.
  • ATtiny25V-10PU --: Low-power 8-bit AVR microcontroller with similar small pin count and flash memory, suitable as a functional replacement for simple remote-control and general-purpose applications.
  • EM78P153S --: Low-cost 8-bit OTP microcontroller from a competing vendor with a similar small package and I/O count, commonly used as a drop-in class alternative for Holtek HT48-series designs.
