Latest HDLC Capable Processors

kris1 — Fri, 15 Jun 2018 05:12:34 GMT

Hi everyone,

I'm having trouble finding recent processors that support HDLC. My current project uses the 8306 but it looks like that one has already been on the market for a while so I'm concerned about longevity with a new design.

The 8555E looks great as far as CPU speed, but also looks a bit dated and development boards seem to be obsolete.

I saw some threads about the UCC and that possibly being able to do HDLC? Does that mean there are other processors which support it which just may not advertise it.

I appreciate everyone's help. I have extensive embedded background but am looking to do my first design with NXP/Freescale. Primary criteria is longevity and an available development board.

Regards,

Kris

Have a great day,

The latest processors with PowerPC core and QE engine are the T-series processors

https://www.nxp.com/products/processors-and-microcontrollers/applications-processors/qoriq-platforms/t-series:QORIQ-POWER-ARCHITECTURE

For example T1023/24 (2xe5500 core) and T1013/14(single e5500 core) have 2 UCCs for HDLC and Transparent protocols up to 50 Mbps full-duplex; 256 channels of HDLC/Transparent per UCC (UMCC). It will be available till April 2029. The same HDLC support you can find on the T1040/42 (till 2027).

Also you can check the P-series processors. For example P1025/P1016 (e500 core) have 4 UCCs and will be available till December 2024.
