标题: Read/verify problem PC48F4400P0VB0E [打印本页]

作者: Test 时间: 2023-9-16 17:09 标题: Read/verify problem PC48F4400P0VB0E

Unfortunately, I'm unable to read and verify PC48F4400P0VB0E (BGA64) with adapter XG-BGA64P2-1.0mm
Each time of verify I have errors with different addresses (about 50~70 differences).
I send T56, adapter and IC to my supplier. Supplier checked IC on own T56 with adapter and also have random errors.
Maybe it makes sense to decrease clock speed in algo xxxP30 BGA64P (proposal from supplier)?

This problem occurs on some chips and it is difficult to find the cause. My chip test did not show this error.

In my previous post about PC28F256P30BF (BGA64) I bought few ICs and I have same problem with new ICs.

My PC48F4400P0VB0E perfectly works with ARM CPU and vxworks OS, but doesn't work well with T56? Is it possible?

I confirm what the author of the post wrote. On different chips, different adapters, different T56 programmers, a reading error appears for the "xxxP30 BGA64P" algorithm.
This is not due to a chip defect.
PC48F4400P0VB0E works successfully in the device, but when working with T56 a reading problem appears.
PC28F256P30BF was successfully read and programmed on the RT809H programmer. The T56 with this chip also has reading errors.
The reading problem occurs with bytes whose contents are FF.

Dear Admin, I'm ready to buy your ICs (few pcs + shipping) to use it with my T56, adapter and ARM motherboard without any errors!
