Hello

Is there a chip that do the HDLC protocol? It gets the packets from the serial line and place at a Rx FIFO ,and get data from Tx FIFO and packetize it and place it on serial line.

Please give IC part number or a circuit that can co this job.

Thanks

hdlc ic

Zilog - HDLC chip, MCU with HDLC
Samsung - MCU(S3C4510 - Arm7) with HDLC
Hitachi - HDLC chip
Infineon - HDLC chip, MCU(C165 UTAH, C165 H) with HDLC
Samsung - MCU(Arm7) with HDLC
AMD - MCU(Am186cc) with HDLC
Motorola - MCU(MC68302 & MPC860 & MPC8260) with HDLC
Rabbit - MCU(R3000) with HDLC
Mindspeed - HDLC chip
infinior - MCU(ims16c - x86 compatible) with HDLC www.infinior.com

Z85C30 & Z85230 - It's popular & best.

Samsung S3C4510 - It's good & cheap.

MPC8260 - It's High-performance & expensive.

hitachi hdlc protocol

Hi

My speed is under 100KHZ (speed is low).

I have a need for HDLC impelementation,The time is critical for me.Is there a solution(a circuit with 74HCXX ICs) with logic ICs that are more available and want less time to find.

Can I implement the HDLC protocol by a C software in 8051 micros for low speed applications?how?

Thanks for your helps.

interface hdlc

HDLC is hardcoding(heavy programming).

flag, NRZ or NRZI, CRC generation, zero insert, etc...

I suggest using HDLC chip or MCU with HDLC.

hdlc arm7

Mindspeed also has some chips which are very powerful on HDLC.

But this chip, now is out of production .....
"we were phasing out AT8993 from the end of last year"
