- Hi,
- I am planning a cheap microcontroller system, and the 68306 from Motorola
- is a microcontroller, which is cheap, i can direct connect DRAM to it,
- it has a little amount of peripheral functions (two serial and some
- prallel IO), the right controller for my application. But Motorola is
- going to abandon production of some of there 68k series like 68000, 68008,
- 68681, 68230, does anyone know how it looks with this type of
- microcontroller ? My chip seller told me, sometimes Motorola is going to
- produce some thousands of this chip, deliver them to their distributers,
- so it can be hard to get some if I need some, but Motorola decided, time
- didn't come to produce them. What are the experiences with the
- availibility of these chips ?
- Another question: I have to connect the system to a PC, and the connect
- should not be too slow, that means >= 500kByte/s, and I should use a
- interface, which is easy to install on the PC-side. That means :
- use of
- 1. ethernet or
- 2. arcnet or
- 3. epp capabilities of the parallel port
-
- For point 1 and 2, I have the sources to get infos and drivers, for point
- 3, I am looking for solutions or chips, which I can use. The chips from
- SMC and Cirrus (SMC34C60 and Cl-CD1283, Cl-CD1284) seem to be oversized
- for that application. Has anyone ideas about chips and drivers, the
- basic-software of my system is not fixed, the decision isn't made, whether
- to use OS9, to program some own basic IO-routines for the little middle-
- fast IO-traffic or to use someother stuff.
