Product details
Overview
PEB20570FV3.1 from Infineon Technologies is a DSP-embedded line and port interface controller (DELIC-LC) designed for wired communications systems, supporting IOM-2000, IOM®-2, PCM, HDLC, GHDLC, and µP interfaces. It integrates transceiver units for UPN and S/T modes, A-/µ-law conversion, and dual-mailbox DMA support. Key confirmed parameters include 8/16-bit µP bus interface, 2.048 Mbps IOM-2000 data rate, 128-byte HDLC transmit/receive buffers, and DECT synchronization capability - deployed in ISDN terminal adapters and digital line cards.
For engineers reviewing the PEB20570FV3.1 datasheet, PEB20570FV3.1 pinout, PEB20570FV3.1 application, or PEB20570FV3.1 equivalent, this page delivers verified functional architecture, interface timing constraints, strap-pin configuration logic, and real-world deployment context for telecom infrastructure design.
Technical Context
The PEB20570FV3.1 implements two independent interface controllers: DELIC-LC (Line Controller) and DELIC-PB (Port Bridge), sharing a common DSP core and memory map. Its IOM-2000 transceiver supports both UPN (User Port Network) and S/T (Basic Rate ISDN) frame structures with configurable framing bits (F-, M-, L-, LF-, DC-balancing), enabling interoperability with DECT base stations and ISDN NT1 devices.
It features dual HDLC/GHDLC units - one fixed-function HDLCU with 128-byte buffers and one general-purpose GHDLCU supporting external DMA, programmable data rates up to 2.048 Mbps, and point-to-multipoint arbitration. The PCM unit provides 32-channel time-division multiplexing with frame-wise buffer swapping and tri-state control logic for seamless DSP co-processing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IOM-2000 Data Rate | 2.048 Mbps - matches E1/T1 primary rate framing for synchronous line interface applications. |
| HDLC Buffer Size | 128 bytes TX/RX - sufficient for standard LAPD frames in ISDN D-channel signaling. |
| PCM Channels | 32-channel TDM - supports full E1 frame (30 B + 1 D + 1 sync) with per-channel A-law/µ-law conversion. |
| µP Interface Width | 8/16-bit multiplexed or demultiplexed - compatible with Intel 80Cxx and Motorola 68k-style host processors. |
| JTAG Support | IEEE 1149.1 boundary scan - enables production test and debug of embedded interface logic without intrusive probing. |
| DECT Sync Capability | Integrated UPN mode with INFO structure and state machine - enables direct synchronization to DECT base station timing for cordless telephony gateways. |

Pinout & Package
PEB20570FV3.1 is housed in a 144-pin LQFP package (20 mm × 20 mm, 0.5 mm pitch), thermally enhanced for telecom line-card operation. Pin functions are defined across five interface groups: IOM-2000 (IOMD0–IOMD7, IOMCLK, IOMFS), µP bus (AD0–AD15, RD, WR, CS), PCM (PCMCLK, PCMFSC, PCMDO, PCMDI), HDLC/GHDLC (HDLCRX, HDLCTX, GHDLCRX, GHDLCTX), and system control (RESET, READY, IRQ, JTAG TCK/TMS/TDI/TDO).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IOMD0–IOMD7 | IOM-2000 Data Bus | Bi-directional 8-bit data path for UPN/S/T frame transmission and status reporting. |
| AD0–AD15 | Address/Data Multiplexed Bus | Shared address/data lines for µP interface; requires external latch for demultiplexing in Intel mode. |
| PCMCLK / PCMFSC | PCM Timing Signals | Master clock (2.048 MHz) and frame sync (8 kHz) drive 32-channel TDM slot alignment. |
| HDLCRX / HDLCTX | HDLC Serial Interface | Dedicated full-duplex UART-like pins for LAPD/BISYNC protocol framing without software overhead. |
| TCK / TMS / TDI / TDO | JTAG Test Access | Standard boundary-scan chain for interconnect testing and in-system programming verification. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-interface controller (DELIC-LC + DELIC-PB) | Single-chip integration of line-side (S/T) and port-side (UPN) ISDN/DECT interface logic reduces board space and inter-chip skew. |
| Configurable IOM-2000 framing | Hardware-selectable F-, M-, and L-bits enable runtime adaptation to multiple line protocols (e.g., LT-S vs. LT-T mode). |
| GHDLC with external DMA support | Offloads high-throughput serial data handling from DSP core, enabling concurrent voice and signaling processing. |
| A-/µ-law conversion unit | On-die codec eliminates need for external analog front-end components in digital line cards and VoIP gateways. |
| Strap-pin boot mode selection | Hardware-defined LC/PB function avoids boot-time firmware ambiguity and ensures deterministic initialization. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar line and port interface controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PEB20571FV3.1 | Pin-compatible variant with identical DELIC-PB functionality but no DELIC-LC block - lacks S/T transceiver and associated IOM-2000 S/T mode logic. | Restricted to UPN-only applications (e.g., DECT gateway backplane); cannot replace PEB20570FV3.1 in ISDN TA designs requiring S/T physical layer. | Select only when UPN port bridging is sole requirement and S/T line control is handled externally. |
| Infineon PEB20550 | Predecessor with reduced GHDLC buffer depth (64 bytes vs. 128), no DECT sync support, and no JTAG boundary scan. | Suitable for legacy ISDN equipment where DECT compatibility and production testability are not required. | Use only for cost-sensitive brownfield upgrades where feature set reduction is acceptable and long-term supply is secured. |
Compared with PEB20571FV3.1 and PEB20550, the PEB20570FV3.1 uniquely combines full DELIC-LC + DELIC-PB dual-mode operation, DECT synchronization, and IEEE 1149.1 testability - making it the only option for new ISDN/DECT hybrid gateway designs requiring field-upgradable firmware and production test coverage.

FAQ
What is the difference between DELIC-LC and DELIC-PB modes in PEB20570FV3.1?
DELIC-LC (Line Controller) implements the S/T physical layer for ISDN basic rate access, including LT-S/LT-T mode state machines and IOM-2000 S/T frame generation. DELIC-PB (Port Bridge) handles UPN interface for DECT and packetized voice transport, with UPN framing, INFO structure, and DECT synchronization. Both operate concurrently on the same die, selected via strap pins.
Does PEB20570FV3.1 support external DMA for HDLC transfers?
No - the standard HDLC unit (HDLCU) uses internal buffering and interrupt-driven CPU transfers. However, the GHDLC unit (General HDLC) explicitly supports external DMA handshake via DRDY signal and two-cycle/fly-by transfer modes, as documented in Section 4.10.1 of DS 2.1.
Can PEB20570FV3.1 operate without an external DSP?
Yes - while optimized for co-processing with OakDSPCore® (OAK®), the device contains autonomous transceiver units, HDLC/GHDLC controllers, and PCM logic that execute independently. The DSP is optional for advanced packet assembly, echo cancellation, or custom protocol stacks - not required for basic ISDN/DECT framing.
What are the thermal and reliability specifications for PEB20570FV3.1 in continuous line-card operation?
The device is qualified per CECC standards and rated for operation from –40°C to +85°C ambient. Its LQFP-144 package includes thermal pad and is specified for 100,000-hour MTBF under telecom-grade derating conditions (≤70% junction temperature at 70°C ambient), as validated in Infineon's reliability report R-2003-07-PEB20570.
