 		 #132945 - 4k... Where?
Responding to: ???'s previous message
Richard Erlacher said:

These work fine for "keeping things running" or adding enhancements quite painlessly. They have 16 or 64 KB FLASH for code space and aon on-board 4KB XRAM, which can be mapped into either code or data space.




Since Dallas was kind enough to send me a DS89C450, I have the Datasheet right here. It says 1k MOVX SRAM in the summary. Where are you getting 4k?


Also... This is a $20 part in small quantities. Hardly low cost.


Atmel's AT89S52 is $2.
