Programming AT89C51 Device ID Error

Question

Even when trying to read the AT89C52, five of which—two new, three removed from working devices—I keep getting a Device IE Error. However, the programmer has read the chip several times and programmed it once. Unfortunately, after this programming, I still get a Device ID error. The programmer correctly programs and reads the 24C16 and 24C01 chips.

The ports and port drivers are good and have been checked several times.

To answer your question about the "Programming AT89C51 Device ID Error" with the "Willar Programmer" for Windows:

It sounds like there could be a few potential issues causing the Device ID error with the AT89C51/52 chips:

1. Chip Compatibility: Make sure that the programmer is fully compatible with the AT89C51/52 microcontrollers. There could be a version of the programmer's software that better supports these chips.

2. Software Configuration: Check the configuration settings in the programming software. Ensure that the settings match the specifications for your specific model of AT89C51/52.

3. Firmware Issue: Sometimes, the programmer's firmware may have bugs. Checking for any available firmware updates and applying them could resolve the issue.

4. Hardware Connection: Re-check the physical connections between the programmer and the microcontroller. A loose connection could cause intermittent issues like the Device ID error.

5. Power Supply: Ensure that the chips are getting the appropriate power supply. A faulty power connection could result in errors.

6. Chip Condition: Since some of the chips are old (removed from working devices), they might have been damaged or worn out. This could cause errors during programming or reading.

7. Programming Algorithm: Ensure that the algorithm used by the programmer matches the requirements for the AT89C51/52. Some older chips might need specific algorithms to be read or programmed correctly.

If none of these solutions work, consulting the documentation for the programmer and reaching out to the manufacturer's support might provide more specific guidance.

Comments

The used chips work fine in the device they were removed from. It appears the programmer is damaged. I've ordered another one, although I don't have much hope for proper operation.
