在本节中，我们将看到 Intel 8080 MPU 和 Intel 8085 MPU 之间的一些差异。
Intel 8080 微处理器是 8085 的前身。两者都是由 Intel 设计和制造的，两者都是 8 位微处理器。
英特尔 8080 微处理器于 1974 年 4 月发布，英特尔 8085 微处理器于 1976 年推出。8085 与 8080 微处理器非常接近，但存在一些细微的变化和修改。
8080和8085微处理器的区别：
| Sr.No. | 8080 microprocessor | 8085 microprocessor |
|---|---|---|
| 1 | There is 8 dedicated pins are there as Data bus (D0 to D7). | There is multiplexed 8 bit data pins are present for data bus (AD0 to AD7). |
| 2 | There is 16 address pins are present (A0 to A15). | There is 8 pins Higher order Address bus (A8 to A15) and 8 multiplexed address bus (AD0 to AD7), and the Address Latch Enable (ALE) pins are present. |
| 3 | The power supply voltage is +5, -5 and +12 volts. | The power supply is only +5 volts. |
| 4 | Single Interrupt pins are there (INT). | With INT, there are four more interrupt pins (TRAP, RST7.5, RST6.5, RST5.5). |
| 5 | Serial Communication facility is not present. | The Serial Communication facility is present with SID, SOD Pins and RIM, SIM instructions. |
| 6 | Additional chips for Clock and system controlling is needed. | No additional chips are needed for clock and system controlling tasks. |
| 7 | It consists of 5 flags (Sign Flag, Zero Flag, Auxiliary Carry Flag, Parity Flag, Carry Flag). | It also consists of 5 flags (Sign Flag, Zero Flag, Auxiliary Carry Flag, Parity Flag, Carry Flag). |
| 8 | Processor speed is upto 3.1 MHz. | Processor speed is upto 6 MHz. |
| 9 | 8080 requires 8224 clock oscillator as well as 8228 system controller to operates. | 8085 is functional with only latches and gates. |
| 10 | 8080 supports upto 256 Input/Output(I/P) ports. | 8085 also supports upto 256 Input/Output(I/P) ports. |
