AFAIK it needs a parallel programmer and has no interface for ISP or IAP Right, but this is a rather old chip (>10 year). A kitchenware programmer can be built successfully with a snip of experience. Look at Peter Dannegger's work, for example (just you'll need to hunt up a DOS-PC for that... :-( or ask Peter for the communication protocol and write your own PC-side program...). I personally don't like those kitchen table designs. Esp. on this forum I have hardly heard anything positive about them. I'm sure a Galep will program these chips. I have a USB based programmer I got via eBay but due to lack of application i haven't build anything yet with those chips. I personally think it was a bad buy anyway due to lack of ISP/IAP. Which leads to another question: is there a nice small 8051 derivate in DIL available that has only 18 pins but offers ISP/IAP or even UART bootloader? Jan Waclawek said:

- but it has ADC No, it does not. It has a comparator (good for building a slow integrating-type ADC). Thanks for correction - I don't remember the data sheet in all aspects. |
