| Seriously I also have to ask what you actually want to 'do' with the value
obtained. The 675, is only an 8pin chip. With the supply pins, and a pulse input to detect speed, you don't have many pins ... |

| Yes, but not unless he writes to the memory.
The read instruction on a real chip, will work without WREN. As I say though people are reporting that you cannot read from the Proteus chip until ... |

| I'd try another memory device. Originally you attached it to an 877, a 5 volt PIC, so it could easily now be defective.
Your 'link' didn't work for me, came back '404' Jay Sorry, corrected |

| You are still not showing a crystal in the circuit. Also the ENVREG pin needs
to be tied to Vdd. Also look at Figure 2-1. This shows the minimum connections required for the PIC to work. You need ... |

| OK, you're using Proteus NOT real parts ???
THAT explains it.. as we all KNOW Proteus is full of bugs, errors and faulty DRCs. You should be aware that if you used real hardware, connected as shown ... |

| No.
You have to send a read command first. The read command is 0x03. Then you then have to send a 24bit address (A19 to 23 are don't care), so 19 bits that matter. Then you send one more byt ... |

| That processor is not better. Minimum voltage for the processor is 4.2V.
Maximum voltage for the memory is 3.6V. They cannot both operate from the same supply voltage and so will not have compatibl ... |

| You really should get a current PIC as the 877 is obsolete and NOT suggested for use anymore. the 16F18877 is one possible upgrade..less money, more features INCLUDING being able to run at 3 volts. TH ... | |
