Application Scenarios & Design Considerations

Z8 CMOS OTP Microcontrollers

Alternative Part Number

  • AT89C4051-12PU --: 8051-compatible 8-bit MCU in 20-pin DIP with similar 12 MHz operation, widely available and a common drop-in replacement for small Z8 designs.
  • PIC16F628A-I/P --: Popular 18-pin DIP 8-bit MCU with comparable I/O and clock speed, easy to source and well supported for legacy Z8 replacement.
  • AT89S4051-12PU --: 8051-core 20-pin DIP MCU with in-system programming and similar performance class, suitable as a functional substitute.
  • AT89C2051-12PU --: 8-bit 8051-compatible MCU in 20-pin DIP with 2KB flash, commonly used as a drop-in replacement for small Z8 microcontrollers in legacy designs.
  • AT89S52-24PU --: 40-pin DIP 8051-compatible MCU with 8KB flash and more I/O, suitable when extra resources are needed to replace the Z86E08 series.
