Pin compatibility
NOTES:
1.
indicates identical operation and register setting.
2. Device microcode is not user-programmable; microcode is supplied by Intel Corporation.
3. A clock frequency of 35 MHz is required to obtain maximum bit-rates (60 MHz for CD2481 Rev. B or later
versions).
4. 256 kbps in sync mode, 2304 kbps in async modes. Applies to Revision D and later CD2231.
5. UNIX character processing is available in ASYNC only.
6. Compatibility with all pins except those supporting channels 2 and 3 on other family members. These pins are “no connect”
or must be pulled-up to VCC by a 4.7-ohm resistor on the CD2231.
