Hi All I would like to make a LAN connection to an LPC2106 design. It seems best to use the SPI interface but I don't know much about SPI Ethernet controller support. After checking around I found the Microchip MCP22S80, a 10M device with SPI connection. But, apart from a simple overview data sheet no more information. Question: Has anyone a good suggestion for a device (I would really like 10/100 if possible but 10M will do for starters). Has any one used the MCP22S80 and would they recommend it? Thanks in advance. Cheers Mark Butcher |

Mark, Bit of a tangent, but I got uIP working on the Olimex LPC-E2124 board so it would be possible to get it working on the 2106 too--it's just bit bashing. The E2124 has a 10M CS8900A on it (popular, low-power, easy to drive). As for SPI & Ethernet, I don't have any direct experience. -- Paul Curtis, Rowley Associates Ltd http://www.rowley.co.uk CrossWorks for MSP430, ARM, and (soon) Atmel AVR processors > -----Original Message----- > From: Mark Butcher [mailto:] > Sent: 27 October 2004 22:19 > To: > Subject: [lpc2000] Ethernet controller for LPC2106 > > Hi All > > I would like to make a LAN connection to an LPC2106 design. > It seems best to use the SPI interface but I don't know much > about SPI Ethernet controller support. > > After checking around I found the Microchip MCP22S80, a 10M > device with SPI connection.

SPI is still free and is probably faster that bit banging. Cheers Mark |

Mark, I have not used this chip. I STRONGLY recommend to get the errata sheet and request the unpublished errata from Microchip for this chip. I had a very bad experience with microchip's CAN controller having problems and trying to get Microchip to admit the problems.

Hi Mark, I do not know of any ethernet controller that supports SPI interface. An alternative would be to use the Xport from lantronix. It gives you ethernet connectivity through a serial port. You can use the maxim MAX3100 or MAX3111 to interface the SPI to UART. Regards, Viron. --- Mark Butcher <> wrote: > > Hi All > > I would like to make a LAN connection to an LPC2106 > design.

Hello... I visited Microchip's Web Site, and that SPI to Ethernet device doesn't have even a datasheet... But seems to be an interesting device. What about using an ISA Card?

It also seems as though it will get (or already has) a new name - the ENC28J60. Still haven't found any alternative which is a shame since it a handy way to expand a design without having to add a bus. Regards Mark Butcher |

I think the total cost of the solution would be around $10. Check out these links: http://www.thearmpatch.com/lpc-sbc2.html http://www.phytec.com/sbc/32bit/pclpc229x.htm |

Has any one > used the MCP22S80 and would they recommend it? Hi, You can try the Wiznet W3100 device. This device runs a TCP/IP stack in hardware for up to 4 simultaneous connections. It can be used as an 8 bit peripheral or through an I2C channel. It can do 10/100. Regards Anton Erasmus-- A J Erasmus |
