Although the 32 I/O pins of a typical 8051 microprocessor provide a complex set of capabilities, we'll focus on the 8051 data bus and associated control signal as shown in Figure 1.

The 8051 is an accumulator-based design with 255 instructions. A basic instruction cycle takes 12 clocks; however, Dallas Semiconductor redesigned the instruction-execution circuitry to reduce the ...

The device (CY7C68013A) integrates an 8051 microprocessor, a serial-interface engine, USB 2.0 transceiver, FIFO, and a general programmable interface.

OneEighty Software has created a Java virtual machine that can run on cheap $1 processors such as the venerable, yet popular, 8051. Called Origin-J, the software is aimed at bringing Java to low cost ...

The MCS 151 and 251 cores are binary-code-compatible with the 8051. (The 251 has additional instructions.) The 151 maintains the 80C51 accumulator-based core compatibility, and the 251 is a ...
