256–16384 bytes 256–4096 bytes The ATmega series features microcontrollers that provide an extended instruction set (multiply instructions and instructions for handling larger program memories), an extensive peripheral set, a solid amount of program memory, as well as a wide range of pins available.
MCS-51-based microcontrollers typically include one or two UARTs, two or three timers, 128 or 256 bytes of internal data RAM (16 bytes of which are bit-addressable), up to 128 bytes of I/O, 512 bytes to 64 KB of internal program memory, and sometimes a quantity of extended data RAM (ERAM) located in the external data space. External RAM and ROM ...
Turbo51 is a compiler for the programming language Pascal, for the Intel MCS-51 (8051) family of microcontrollers. It features Borland Turbo Pascal 7 syntax, support for inline assembly code, source-level debugging, and optimizations, among others. The compiler is written in Object Pascal and produced with Delphi.

The Z80 uses 252 out of the available 256 codes as single byte opcodes ("root instruction" most of which are inherited from the 8080); the four remaining codes are used extensively as opcode prefixes: [46] CB and ED enable extra instructions, and DD or FD select IX+d or IY+d respectively (in some cases without displacement d) in place of HL.
An AT89c2051 microcontroller in circuit. The Atmel AT89 series is an Intel 8051-compatible family of 8 bit microcontrollers (μCs) manufactured by the Atmel Corporation.. Based on the Intel 8051 core, the AT89 series remains very popular as general purpose microcontrollers, due to their industry standard instruction set, their low unit cost, and the availability of these chips in DIL (DIP ...

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.
