Product details
Overview
PEB20321H-V22 from Infineon Technologies is a multichannel network interface controller for HDLC protocol handling, implementing the MUNICH32X architecture with PCI and local bus interfaces. It supports up to 32 HDLC channels, operates at 66 MHz PCI clock, integrates dual DMA controllers, and delivers deterministic latency for telecom access equipment.
For engineers reviewing the PEB20321H-V22 datasheet, PEB20321H-V22 pinout, PEB20321H-V22 application, or PEB20321H-V22 equivalent, key selection criteria include HDLC channel count, PCI 2.2 compliance, LBI master/slave arbitration capability, and IOM-2 B/D-channel timing alignment in ISDN terminal adapters.
Technical Context
The PEB20321H-V22 implements a dedicated HDLC protocol engine with hardware CRC-16/CCITT generation and verification per channel, supporting synchronous serial framing (TMB/TMR/TMA) and V.110/X.30 adaptation layers. Its PCI interface complies with Revision 2.2 and supports memory-mapped I/O with byte/word/dword access.
The device integrates two independent DMA engines - one for PCI-to-local bus transfers and another for LBI peripheral data movement - with descriptor-based buffer management and interrupt coalescing. The IOM-2 interface provides native B-channel (64 kbps) and D-channel (16 kbps) framing synchronized to PCM timeslots.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| HDLC Channels | 32 independent channels with per-channel address filtering and CRC-16 engine |
| PCI Interface | 32-bit, 33/66 MHz, PCI Rev 2.2 compliant with configuration space registers |
| LBI Width | 16-bit multiplexed or demultiplexed local bus with programmable wait states |
| IOM-2 Support | Full B-channel (64 kbps), D-channel (16 kbps), and monitor channel timing alignment |
| Serial PCM Core | 8-bit or 16-bit time-slot assignment with bit-shift capability for T1/E1 framing |
| Interrupt Sources | 16-level prioritized interrupt vectoring with per-channel, per-interface, and DMA completion flags |
| Operating Voltage | 3.3 V ± 0.3 V core and I/O supply; 5 V tolerant on selected LBI control pins |
Pinout & Package
PEB20321H-V22 is housed in a 176-pin TQFP package (P-TQFP-176-1), thermally enhanced with exposed thermal pad. Pin functions are grouped into PCI interface (AD[31:0], C/BE[3:0]#, PAR, FRAME#, TRDY#, STOP#), LBI interface (LAD[15:0], LWR#, LRD#, LCLK, LRDY), SSC/IOM-2 (SCLK, SDATA, SFRM, MX, MR), and power/ground (VCCIO, VCCINT, GND).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AD[31:0] | PCI Address/Data Multiplexed Bus | Time-multiplexed 32-bit address and data path; requires external latch for demultiplexing |
| LAD[15:0] | Local Address/Data Bus | 16-bit bidirectional bus supporting both multiplexed and demultiplexed modes via LMODE pin |
| SCLK / SDATA / SFRM | Synchronous Serial Control Interface | Master-clock-driven serial interface for connecting to line interface units (LIUs) or codec devices |
| MX / MR | IOM-2 Monitor Channel Signals | Provide real-time monitoring of B/D-channel activity without disrupting primary data flow |
| RESET# | Asynchronous Active-Low Reset Input | Initiates full internal register reset and disables all interfaces until deasserted and stabilized |
Key Features
| Feature | Design Value |
|---|---|
| Per-Channel HDLC Engine | Hardware CRC-16, flag detection, bit stuffing/unstuffing, and address recognition eliminate host CPU overhead |
| Dual DMA Architecture | Separate PCI-to-LBI and LBI-peripheral DMA engines enable concurrent high-throughput data movement |
| IOM-2 Native Timing | On-chip clock dividers and phase-aligned frame sync ensure precise B/D-channel slot placement in E1/T1 systems |
| Descriptor-Based Buffer Management | Linked-list descriptors with ownership bits allow zero-copy packet processing and dynamic buffer allocation |
| LBI Master/Slave Arbitration | Programmable priority and mailbox registers enable deterministic multi-peripheral control without external logic |

Equivalent & Alternatives
The following parts are listed as comparable options for similar multichannel HDLC controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PEF20321H-V22 | Same die, identical functionality; differs only in CECC qualification and extended temperature screening | Required for military/aerospace programs requiring CECC-90000 compliance | Select when extended temp range (-40°C to +105°C) and radiation-hardened test flow are mandatory |
| PEB20320H-V21 | Lacks TMA/V.110 support, reduced LBI DMA bandwidth, no IOM-2 monitor channel (MX/MR) | Suitable for basic ISDN TA designs without V.110 bridging or real-time monitoring needs | Choose only for cost-sensitive legacy upgrades where V.110 and monitor features are unused |
Compared with PEF20321H-V22, the PEB20321H-V22 offers identical feature set with commercial-grade screening, while PEB20320H-V21 omits critical protocol extensions and monitoring capability required for next-generation access gateways.

FAQ
Does PEB20321H-V22 support PCI-X or PCIe?
No. The PEB20321H-V22 implements PCI Local Bus Specification Revision 2.2 only, operating at 33 MHz or 66 MHz in 32-bit mode. It lacks PCI-X arbitration enhancements and has no PCIe physical layer or transaction layer logic. Systems requiring PCIe must use a bridge IC or select a newer-generation controller.
What is the maximum number of HDLC channels that can operate simultaneously at full rate?
All 32 HDLC channels can operate concurrently at full rate-each supporting up to 2.048 Mbps (E1) or 1.544 Mbps (T1) with independent CRC, address filtering, and interrupt generation. Throughput is limited by PCI bus bandwidth and host DMA efficiency, not by internal channel arbitration.
Is external memory required for descriptor tables or frame buffers?
Yes. Descriptor tables, receive/transmit buffers, and protocol state storage reside in external host memory. The PEB20321H-V22 contains only internal configuration and status registers-not packet RAM. Host system must allocate coherent memory regions accessible via PCI or LBI.
Can the IOM-2 interface be used without the PCM core?
No. The IOM-2 interface depends on the Serial PCM Core for clock derivation, frame synchronization, and time-slot mapping. Disabling the PCM core disables IOM-2 operation. Both blocks are functionally coupled and share the same clock domain and configuration registers.
