#151990 - P89C669 Obsolete, looking for replacement. |
Got This message from NXP:
"The P89C669 will be discontinued. Orders can be placed till October 2009. The last delivery will be in Dec 2009." As we are using this chip in production I have started looking for a replacement. It is an old project. We started about 13 years ago with a standard 8052 chip. In time the program has grown and we have switched processor a couple of times. It has always been possible to find another 51-derivative with the required spec. Moving to a totally different platform, would cause me a lot of work. Therefore, as first choice, I am looking for another 51. The MX-core has a lot of benefits that I like. But ofcourse there is always bankswitching.... I have found AT89C51RE2, I think it would do the job. Does anyone know about other similar 51-chips? Key requirements, minimum as 669, in terms of: >= 24MHz/6clock = 4MIPS >= 96k Flash >= 2k RAM 2 Uarts I2C, SPI or other synchronus. ISP |
