Intel produced a series of development systems for the 8080 and 8085, known as the MDS-80 Microprocessor System. The original development system had an 8080 processor. Later 8085 and 8086 support was added including ICE (in-circuit emulators). It is a large and heavy desktop box, about a 20" cube (in the Intel corporate blue color) which ...
The PIA is most commonly packaged in a 40 pin DIP package. The PIA is designed for glueless connection to the Motorola 6800 style bus , and provides 20 I/O lines, which are organised into two 8-bit bidirectional ports (or 16 general-purpose I/O lines) and 4 control lines (for handshaking and interrupt generation).
40 pin DIP The KR580VM80A ( Russian : КР580ВМ80А ) is a Soviet microprocessor , a clone of the Intel 8080 CPU . [ 1 ] [ 2 ] Different versions of this CPU were manufactured beginning in the late 1970s, the earliest known use being in the SM1800 computer in 1979.
The 8255 is a member of the MCS-85 family of chips, designed by Intel for use with their 8085 and 8086 microprocessors and their descendants. [1] It was first available in a 40-pin DIP and later a 44-pin PLCC packages. [2] It found wide applicability in digital processing systems and was later cloned by other manufacturers.
Closeup of the pins of a pin grid array The pin grid array at the bottom of prototype Motorola 68020 microprocessor The pin grid array on the bottom of an AMD Phenom X4 9750 processor that uses the AMD AM2+ socket. A pin grid array (PGA) is a type of integrated circuit packaging. In a PGA, the package is square or rectangular, and the pins are ...
The instruction set architecture (ISA) that the computer final version (SAP-3) is designed to implement is patterned after and upward compatible with the ISA of the Intel 8080/8085 microprocessor family. Therefore, the instructions implemented in the three SAP computer variations are, in each case, a subset of the 8080/8085 instructions.
Among the first of the AVR line was the AT90S8515, which in a 40-pin DIP package has the same pinout as an 8051 microcontroller, including the external multiplexed address and data bus. The polarity of the RESET line was opposite (8051's having an active-high RESET, while the AVR has an active-low RESET ), but other than that the pinout was ...
40-pin DIP National Semiconductor 's SC/MP (pronounced scamp ) for Simple Cost-effective Micro Processor , is an early 8-bit microprocessor which became available in April 1976. It was designed to allow systems to be implemented with the minimum number of additional support chips .
