The Intel 8085 ("eighty-eighty-five") is an 8-bit microprocessor produced by Intel and introduced in March 1976. [2] It is the last 8-bit microprocessor developed by Intel. It is 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 8253 and 8254 are programmable interval timers (PITs), which perform timing and counting functions using three 16-bit counters. [ 1 ] The 825x family was primarily designed for the Intel 8080 / 8085 -processors, but were later used in x86 compatible systems.
The NEC μCOM series is a series of microprocessors and microcontrollers manufactured by NEC in the 1970s and 1980s. The initial entries in the series were custom-designed 4 and 16-bit designs, but later models in the series were mostly based on the Intel 8080 and Zilog Z80 8-bit designs, and later, the Intel 8086 16-bit design.
The DIN 41612 connector has different pin assignments assigned by various manufacturers, such as Kontron, J&K, ELZET80, Conitec, etc. [3] N8VEM homebrew computing project uses ECB and provides a large number of various ECB cards and a couple of ECB backplanes along with Z80 processor socket shim adapters to allow a great number of retro ...
Intel had already produced 40,000 units of the 8080 at the direction of the sales section before Shima characterized the prototype. After working out some typical last-minute issues, Intel introduced the product in March 1974. [11] It was released a month later as requiring Low-power Schottky TTL (LS TTL) devices. The 8080A fixed this flaw. [14]
Intel produced a CMOS 8085 (80C85) used in battery-powered portable computers, such as the Kyocera-designed laptop from April 1983, also sold by Tandy (as TRS-80 Model 100), Olivetti, and NEC. In following years, however, CMOS versions of the Z80 (from both Zilog and Japanese manufacturers) would dominate this market as well, in products such ...
Below is the full 8086/8088 instruction set of Intel (81 instructions total). [2] These instructions are also available in 32-bit mode, in which they operate on 32-bit registers (eax, ebx, etc.) and values instead of their 16-bit (ax, bx, etc.) counterparts.
The pin layout of the latter completely matched that of Intel's 8080A CPU. In 1986 this CPU received a new part number to conform with the 1980 Soviet integrated circuit designation and became known as the KR580VM80A (КР580ВМ80А), the number it is most widely known by today (the KR580VV51A and KR580VV55A peripheral devices went through ...
