8085ah 2 datasheet

Intel 8085 A-2 is 200 ns. It has 80 basic instructions and 246 opcodes. Figure 1 shows the block diagram of Intel 8085A. It consists of three main sections, an arithmetic and logic unit a timing and control unit and several registers. These important sections are described as under. ALU

8085AH-2 systems above 3.9 MHz, the 8085 CLK(OUT) does not satisfy 8237A-5 clock LOW and HIGH time requirements. In this case, an external clock should be used to drive the 8237A-5. DMA OPERATION The 8237A is designed to operate in two major cy-cles. These are called Idle and Active cycles. Each device cycle is made up of a number of states. The Here are the details of the read cycle, from the datasheet, on page 1-25. Keep in mind that t CYC is 320 ns (3 MHz, 8085AH), but could be as short as 167 ns (6 MHz, 8085AH-1). t AD is the total memory access time from the CPU's point of view, from the time the address is stable to when the data must be valid. It is given as 575 ns for the 8085AH. SAB 8085AH-2-P datasheet, cross reference, circuit and application notes in pdf format.

It is a software-binary compatible with the more-famous Intel 8080 with only two minor instructions added to support its added interrupt and serial input/output features. The Intel 8085A is a complete 8 bit parallel Central Processing Unit (CPU). Its instruction set is 100% software compatible with the 8080A microprocessor, and it is designed to improve the present 8080A's performance by higher system speed.
