Product details
Overview
PEB20320H-V34 from Infineon Technologies is a multichannel HDLC protocol controller IC supporting up to 32 full-duplex PCM data channels at 2048/4096/1544/1536 Kbit/s, performing layer-2 HDLC/V.110/X.30 framing and transparent DMI mode transmission up to 38.4 Kbit/s, with CRC-16/32 generation/checking and zero-bit insertion per channel - deployed in ISDN D-channel controllers and digital PABX host interfaces.
For engineers reviewing the PEB20320H-V34 datasheet, PEB20320H-V34 pinout, PEB20320H-V34 application, or PEB20320H-V34 equivalent, key selection criteria include serial interface timing compliance (Intel/Motorola bus modes), time-slot concatenation flexibility for H0/H11/H12 superchannels, shared memory descriptor management, and boundary-scan test support per IEEE 1149.1.
Technical Context
The PEB20320H-V34 implements a dedicated HDLC protocol engine with per-channel programmable bit processing: automatic flag detection/stuffing, interframe fill handling, and configurable CRC-16 or CRC-32 with transparent CRC option. It supports dynamic time-slot allocation across non-consecutive PCM frames for ISDN H0 (384 Kbit/s), H11 (1536 Kbit/s), and H12 (1920 Kbit/s) superchannels.
Its dual-mode microprocessor interface operates in Intel 80C86-compatible or Motorola 68000-compatible timing, with DMA priority arbitration and boundary-scan test unit compliant with IEEE 1149.1. Data flow is managed via shared memory descriptors - transmit/receive descriptors contain buffer pointers, length, status, and control flags - enabling host processor coexistence with up to four MUNICH32 devices on one PCM highway.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Protocol Support | HDLC, V.110, X.30, LAPD, SDLC, LAPB, DMI Modes 0–2 - enables interoperability with ISDN basic rate access and legacy telecom equipment. |
| Max Channels | 32 independent full-duplex data channels - allows centralized D-channel control for up to 32 ISDN BRI lines or multiplexed terminal aggregation. |
| PCM Highway Rates | 2048 Kbit/s (CEPT/E1), 4096 Kbit/s, 1544 Kbit/s (T1), 1536 Kbit/s - supports global telephony infrastructure standards without external rate adaptation logic. |
| CRC Options | CRC-16 or CRC-32 per channel, with transparent CRC mode - ensures frame integrity verification matching specific protocol stack requirements. |
| Time-Slot Flexibility | Concatenation of any non-consecutive time slots into superchannels - enables H0 (384 Kbit/s), H11 (1536 Kbit/s), H12 (1920 Kbit/s) ISDN configurations. |

Pinout & Package
PEB20320H-V34 is housed in a P-MQFP-160-1 package: 160-pin plastic metric quad flat pack with 0.65 mm lead pitch, body size 24 × 24 mm, and standard JEDEC MO-137AC footprint - suitable for high-density telecom PCB layouts requiring thermal and signal integrity control.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLKIN | Master clock input | Accepts 16.384 MHz or 32.768 MHz reference for internal PLL - determines PCM frame timing and HDLC bit-rate accuracy. |
| RESET | Asynchronous active-low reset | Initializes all registers, clears descriptor queues, and forces default configuration - required before host software initialization. |
| INT | Interrupt request output | Open-drain signal asserted on channel event (e.g., frame complete, error, descriptor exhausted) - enables efficient host interrupt-driven I/O. |
| RD/WR | Read/write strobe (Intel mode) | Controls direction of data transfer on AD[15:0] bus - synchronizes host read/write cycles with internal register or memory access. |
| DS/AS | Data strobe/address strobe (Motorola mode) | Separates address setup from data transfer timing - ensures correct latching in 68000-based systems. |
| TxD0–TxD31 | Transmit data outputs | 32 parallel serial data outputs - each mapped to an individual HDLC channel's transmit path after framing and CRC insertion. |
| RxD0–RxD31 | Receive data inputs | 32 parallel serial data inputs - each feeds independent HDLC receive engine for flag detection, CRC checking, and de-framing. |
| TSI[7:0] | Time slot identification bus | 8-bit bus indicating current PCM time slot index - used by host to correlate channel activity with physical time-slot position on highway. |
Key Features
| Feature | Design Value |
|---|---|
| Per-channel HDLC bit processing | Independent flag detection/stuffing, zero-bit insertion, and CRC-16/32 generation/checking - eliminates need for external protocol offload logic per channel. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar multichannel HDLC protocol controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Infineon PEB20321H-V34 | Same MUNICH32 core but with updated revision (V3.4a), minor errata fixes, and extended AC timing margins. | Identical functional scope; intended for new designs requiring latest characterization data and wafer lot traceability. | Select when sourcing new production builds requiring documented revision control and latest electrical validation. |
| Intel 82530 SA | Single-chip HDLC controller with 4 channels, integrated UARTs, and PCI interface - lacks time-slot concatenation and PCM highway support. | Suitable for PC-based communications cards or low-channel-count modems, not for ISDN D-channel aggregation or E1/T1 line cards. | Choose only for cost-sensitive, low-channel-count applications where PCM highway integration is unnecessary. |
Compared with PEB20320H-V34, the PEB20321H-V34 offers identical functionality with enhanced production traceability and tighter AC specs, while the Intel 82530 SA provides PCI-native integration at the expense of scalability and PCM infrastructure compatibility.

FAQ
What bus interface modes does PEB20320H-V34 support?
The PEB20320H-V34 supports both Intel 80C86-compatible and Motorola 68000-compatible microprocessor bus timing. In Intel mode, RD/WR strobes control data transfer; in Motorola mode, DS/AS signals separate address and data phases. Both modes use the same AD[15:0] multiplexed address/data bus and share identical register mapping and descriptor structure.
Does PEB20320H-V34 support ISDN H11 and H12 superchannels?
Yes - the device supports concatenation of arbitrary non-consecutive PCM time slots to form H0 (384 Kbit/s), H11 (1536 Kbit/s), and H12 (1920 Kbit/s) superchannels. This is implemented via programmable time-slot assignment registers that map physical slots to logical channels independently for transmit and receive paths, meeting ITU-T I.430/I.431 requirements.
How is memory managed between host processor and PEB20320H-V34?
Memory is shared via a dual-port RAM architecture: the host writes transmit descriptors and buffers into designated memory regions, and the PEB20320H-V34 reads them autonomously during DMA transfers. Similarly, received data is written into host-allocated buffers with status flags updated in receive descriptors - enabling lock-free, interrupt-driven data flow without CPU polling overhead.
Is boundary scan test supported on PEB20320H-V34?
Yes - the device integrates a fully compliant IEEE 1149.1 boundary scan test unit with TAP controller, instruction register, and boundary-scan cell chain covering all primary I/O pins. Test access is provided via TCK, TMS, TDI, and TDO pins, enabling interconnect testing, stuck-at fault detection, and in-system programming verification per JTAG standard.
