STC 8051 MicroControllerSTC8051 series, is a 8-bit single-chip microcontroller with a fully compatible instruction set with industrial-standard 80C51 series microcontroller. There is 64K bytes flash memory embeded for appliaction program, which is shared with In-System-Programming code.In-System- ...
8051 / 8052 Instruction SetAuthor : Craig Steiner Source : 8052.com ACALL: Absolute Call ADD, ADDC: Add Accumulator (With Carry) AJMP: Absolute Jump ANL: Bitwise AND CJNE: Compare and Jump if Not Equal CLR: Clear Register CPL: Complement Register DA: Decimal Adjust DEC: Decrement Register...
The 8051 instruction set allows for instructions of variable length from 1 to 3 bytes. In a single-clock-per-byte-fetch system this means each instruction takes at least as many clocks as it has bytes to execute. The majority of instructions in the AT89LP51RD2/ED2/ID2 fol- low this ...
Q2. What are some of the features of the 8051 microcontroller architecture? Ans:Some of the key features of the 8051 architecture include a simple instruction set, low power consumption, and compact size. It also has a limited amount of memory and peripheral support compared to more modern mic...
M1,M0 : Used for mode selection.Because the Timers of 8051 can be set in 4-different modes. M1 0 0 1 M0 0 1 0 Mode 0 1 2 Operation 13-bit timer mode 8-bit THx + 5-bit TLx (x= 0 or 1) 16-bit timer mode 8-bit THx + 8-bit TLx 8-bit auto reload 8-bit auto reload ...
A range of fast, 8-bit, 8051-compatible microcontrollers that execute the MCS®51 instruction set. Royalty-free; a resource- and cost-effective solution for offloading main processors in complex SoCs.
When set, this allows Timer 2 to be configured as an up/down counter. * User software should not write 1s to reserved bits. These bits may be used in future 8051 family products to invoke new features. In that case, the reset or inactive value of the new bit will be 0, and its ...
The 8051 instruction set allows for instructions of variable length from 1 to 3 bytes. In a single- clock-per-byte-fetch system this means each instruction takes at least as many clocks as it has bytes to execute. The majority of instructions in the AT89LP3240/6440 follow this rule: the...
www.ti.com The microcontroller core is 8051 instruction set compatible. The microcontroller core is an optimized 8051 core that executes up to three times faster than the standard 8051 core, given the same clock source. That makes it possible to run the device at a lower external clock ...
