How to Flash P89C52X2BN MCU?

Hi all,

I need to program two old MCUs: P89C52X2BN and P89C52RD2.

For the P89C52RD2, I understand it supports ISP via serial. But not known how to active and ISP/IAP protocol?

For the P89C52X2BN, How do I flash it? Does it need a parallel programmer? If need, how protocol and how to active flash mode?

I'm mainly looking for the official programming documentation for these two chips (especially the X2BN), so I can reference the correct flash programming interface and timing. If you have the datasheet's programming section or a link, please share.

Thanks!

Hello

I apologize for the inconveniences this might cause you, The P89C52 family is no longer manufactured and because of this is no longer supported, the information for this family is no longer available.

If it could work for you there is this information for the 89C51; Important: I can't confirm or test whenever this information work and/or apply for the 89C52.

In-circuit and In-application programming of the 89C51Rx+/Rx2/66x microcontrollers

Re: How to Flash P89C52X2BN MCU?Sorry, XSP6100N is far too costly, equivalent to 6-12 months of an average person's wages. Therefore I will read the Docs and try to flash it myself. XSP6100N can do, But I cannot afford it, Thanks.Re: How to Flash P89C52X2BN MCU?This AN can be used for P89C5xRx2, But missing P89C5xX2, This AN is the correct type of document, But it's just missing P89C5xX2. Thanks!
