ATmega328. ATmega328P in 28-pin narrow dual in-line package (DIP -28N) ATmega328P in 32-pin thin quad flat pack (TQFP -32) Die of ATmega328P. The ATmega328 is a single- chip microcontroller created by Atmel in the megaAVR family (later Microchip Technology acquired Atmel in 2016). It has a modified Harvard architecture 8-bit RISC processor core.
ATmega328 P in 28-pin narrow dual in-line package (DIP -28N). It is commonly found on Arduino boards. AVR is a family of microcontrollers developed since 1996 by Atmel, acquired by Microchip Technology in 2016. These are modified Harvard architecture 8-bit RISC single-chip microcontrollers.
The Zilog Z80 is an 8-bit microprocessor designed by Zilog that played an important role in the evolution of early computing. Software-compatible with the Intel 8080, it offered a compelling alternative due to its better integration and increased performance. The Z80 boasted fourteen registers compared to the 8080's seven, along with additional ...
An 8-bit register can store 2 8 different values. The range of integer values that can be stored in 8 bits depends on the integer representation used. With the two most common representations, the range is 0 through 255 (2 8 − 1) for representation as an binary number, and −128 (−1 × 2 7) through 127 (2 7 − 1) for representation as two's complement.
The Intel 8080 ("eighty-eighty") is the second 8-bit microprocessor designed and manufactured by Intel. It first appeared in April 1974 and is an extended and enhanced variant of the earlier 8008 design, although without binary compatibility. [3] The initial specified clock rate or frequency limit was 2 MHz, with common instructions using 4, 5 ...
Motorola 68000. MOS 6502. The 6800 (" sixty-eight hundred ") is an 8-bit microprocessor designed and first manufactured by Motorola in 1974. The MC6800 microprocessor was part of the M6800 Microcomputer System (latter dubbed 68xx[ 1 ]) that also included serial and parallel interface ICs, RAM, ROM and other support chips.
Instructions per second. Instructions per second (IPS) is a measure of a computer 's processor speed. For complex instruction set computers (CISCs), different instructions take different amounts of time, so the value measured depends on the instruction mix; even for comparing processors in the same family the IPS measurement can be problematic.
Motorola 6809. The Motorola 6809 (" sixty-eight-oh-nine ") is an 8-bit microprocessor with some 16-bit features. It was designed by Motorola 's Terry Ritter and Joel Boney and introduced in 1978. Although source compatible with the earlier Motorola 6800, the 6809 offered significant improvements over it and 8-bit contemporaries like the MOS ...
