I work on plasma etchers at a small semiconductor plant and I’ve got a tool ( Drytek T) that uses an old intel microcontroller in the RF. Looking for Intel ?

Any information that anybody can give me would be greatly appreciated. That means an compatible processor can now execute million instructions per second.

Intel 8751

The operations specified by the most significant nibble are as follows. XRL addressA.

Overflow flagOV. I have explained the 7-segement LED displays in Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at Views Read Edit View history. You have to PROM burner to erase its memory and program it again. This page was last edited on 1 Decemberat This part was available in a ceramic package with a clear quartz window over the microcontrollet of the die so UV microcontdoller could be used to erase the EPROM memory.


Set when banks at 0x08 or 0x18 are in use. JNB bitoffset jump if bit clear.

The is designed as a Harvard architecture with segregated memory Data and Instructions ; it can only execute code fetched microcontoller program memory, and has no instructions to write to program memory.

JNZ offset jump if non-zero. How to Select a Microcontroller for Project. Instruction mnemonics use destinationsource operand order.

ORL addressdata. SJMP offset short jump.

The 8031/8751 microcontroller

It features extended instructions [34] — micocontroller also the microcontgoller guide [35] — and later variants with higher performance, [36] also available as intellectual property IP.

The microcontroller is connected w Instructions are all 1 to 3 bytes long, consisting of an initial opcode byte, followed by up to 2 bytes of operands. The original Intel ran at 12 clock cycles per machine cycle, and most instructions executed in one or two microcontoller cycles.

As we have discussed earlier, that the delay length depends on the 3 factors- a number of clock per machine; b Crystal oscillator valu The absolute memory address is formed by the high 5 bits of the PC and the 11 bits defined by the instruction. Baud Rate is the data transmission rate that determines the symbols per second for serial communication.

They can not be accessed indirectly via R0 or R1; indirect access to those addresses will access the second half of IRAM. Different ways to generate delays in There is also a two-operand compare and jump operation. RRC A rotate right through carry. For the latter, there are explicit instructions to jump on whether or not the accumulator is miicrocontroller. In other projects Wikimedia Commons.

Retrieved 5 January And yes, they are only programable once. We have several suppliers that specialize in very old IC’s that are no longer manufactured and I think I can get several of the original intel ‘s. Retrieved 6 January That means microcontrolle is one time programmable you can’t put anything again into it unless it has an EPROM like window to erase it using UV light.
