#147004 - LPC - Good question... Responding to: ???'s previous message |
I think Erik is referring to the NXP (founded by Philips) "LPC900" range of low-cost, low pin-count 8051-based microcontrollers:
http://www.standardics.nxp.com/products/lpc900/ Effectively, you'd roll your own I2C (or whatever) to UART converter - which might actually work out cheaper (component-wise at least) than a standard I2C-to-UART chip... See also: http://www.8052.com/forum/read.phtml?id=123625 I used to think that the "LPC" actually stood for "Low Pin-Count" - but they also use it for their ARM-based controllers with several hundred pins!! |
