Product details
Overview
PEB20534H10-V21 from Infineon Technologies is a DMA-supported quad-channel serial communication controller (DSCC4) designed for high-reliability datacom and telecom infrastructure. It integrates four independent SCC cores, PCI and local bus interfaces, dual central FIFOs (8 KB TX/RX), and a programmable DMA controller. Supports HDLC/SDLC, PPP, LAPB/LAPD, and transparent modes with full-duplex operation up to 8 Mbps per channel - deployed in HSSI DCE/DTE adapters and general data multiplexing systems.
For engineers reviewing the PEB20534H10-V21 datasheet, PEB20534H10-V21 pinout, PEB20534H10-V21 application, or PEB20534H10-V21 equivalent, key selection criteria include multi-protocol SCC flexibility, PCI 2.1 compliance, hardware-accelerated HDLC framing, deterministic interrupt latency under 1.2 µs, and support for synchronous serial (SSC) and general-purpose port (GPP) expansion.
Technical Context
The DSCC4 implements four fully independent Serial Communication Controller (SCC) cores, each with dedicated transmit/receive FIFOs, baud rate generators, clock recovery (DPLL), and protocol state machines for HDLC, SDLC, PPP, and transparent modes. All SCCs share a unified DMA engine and central 8 KB transmit/receive FIFO memory space.
It features dual host interface options: PCI 2.1-compliant bus (33 MHz, 32-bit) and configurable de-multiplexed/multiplexed local bus (LBI) supporting big/little-endian byte swapping, programmable wait states, and ready-signal arbitration. The Multi-Function Port (MFP) integrates SSC, GPP, and LBI interrupt generation with vectorized servicing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Protocol Support | HDLC/SDLC, PPP (bit/octet/asynchronous), LAPB/LAPD, Extended Transparent - enables interoperability with legacy telecom framing standards and modern packetized links. |
| Max Data Rate per SCC | 8 Mbps - supports E1/T1 line-rate framing and HSSI adapter applications without external rate-limiting logic. |
| DMA Engine | Descriptor-based, hold-bit and last-address control modes - eliminates CPU polling overhead and enables zero-copy transfers between host memory and SCC FIFOs. |
| Central FIFO Size | 8 KB total (4 KB TX + 4 KB RX) - buffers bursty traffic across all four channels, reducing interrupt frequency and improving throughput predictability. |
| PCI Interface | PCI 2.1 compliant, 33 MHz, 32-bit address/data - ensures plug-and-play integration into standard x86 and PowerPC-based communications platforms. |
| SCC Clock Recovery | Digital Phase-Locked Loop (DPLL) with ±100 ppm tolerance - maintains frame synchronization on noisy or jittered serial streams without external clock conditioning. |
| Interrupt Latency | <1.2 µs worst-case - guarantees timely response to frame end, CRC error, or buffer threshold events in real-time protocol stacks. |
Pinout & Package
PEB20534H10-V21 is housed in a 256-pin PQFP (Plastic Quad Flat Package) with 0.5 mm pitch, thermally enhanced for sustained operation in telecom line cards and network interface modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PCI_AD[31:0] | PCI Address/Data Multiplexed Bus | Carries time-multiplexed address and data during PCI transactions; requires external latch for demultiplexing in non-burst mode. |
| PCI_C/BE[3:0]# | PCI Command/Byte Enable | Defines transaction type (I/O read/write, memory read/write) and active byte lanes - critical for correct register and FIFO access mapping. |
| PCI_CLK | PCI System Clock Input | 25–33 MHz reference driving all PCI interface timing; must meet PCI 2.1 setup/hold requirements for reliable enumeration. |
| SCC_TxCLK[3:0] | Per-Channel Transmit Clock Input | Independent clock source per SCC for synchronous transmission; supports external or internal BRG-derived timing. |
| SCC_RxCLK[3:0] | Per-Channel Receive Clock Input | Enables synchronous or asynchronous receive operation; DPLL locks to incoming stream when used in recovered-clock mode. |
| GPP_IO[7:0] | General Purpose Port I/O | Configurable 8-bit bidirectional port for status signaling, modem control (RTS/CTS/CD), or custom peripheral interfacing. |
Key Features
| Feature | Design Value |
|---|---|
| Quad SCC Architecture | Four independent, register-compatible serial controllers sharing DMA and FIFO resources - enables concurrent multi-protocol link handling (e.g., two HDLC + one PPP + one transparent) without software contention. |
| Hardware HDLC Framing | On-the-fly flag detection, bit stuffing, CRC-16/32 generation/checking, and address field filtering - offloads 100% of Layer-2 framing from host CPU. |
| Programmable Local Bus (LBI) | Supports multiplexed/de-multiplexed modes, 8/16/32-bit data width, and configurable wait states - simplifies integration with legacy DSPs, microcontrollers, or ASICs lacking PCI. |
| Synchronous Serial Control (SSC) | Full-duplex SPI-like interface with programmable clock polarity/phase - enables direct connection to external PHYs, codec ICs, or FPGA-based line interfaces. |
| Vectorized Interrupt System | Priority-encoded, channel-specific interrupt vectors for SCC, DMA, FIFO, and MFP events - eliminates software polling and enables deterministic ISR dispatch. |
Applications
| HSSI DCE Adapter | HSSI DTE Adapter |

Equivalent & Alternatives
The following parts are listed as comparable options for similar multi-protocol serial controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Intel 82536 | Single-channel HDLC controller with integrated T1/E1 framer; no PCI interface or DMA engine. | Limited to point-to-point T1/E1 line termination; lacks multi-protocol flexibility and quad-channel concurrency. | Select when only one high-integrity T1 link is required and host-side DMA is already implemented. |
| Motorola MC68360 | Integrated PowerPC core + dual SCCs + QUICC engine; requires full embedded firmware development. | Targeted at standalone communications processors; not a drop-in replacement for host-attached PCI designs. | Choose for deeply embedded, firmware-controlled gateways where real-time OS and protocol stack porting are acceptable. |
Compared with Intel 82536 and MC68360, PEB20534H10-V21 uniquely delivers quad-channel protocol agility, PCI-native integration, and hardware-accelerated framing in a single chip - making it optimal for host-based telecom line cards requiring scalable, low-CPU-overhead serial connectivity.

FAQ
Does PEB20534H10-V21 support PCI Express?
No. PEB20534H10-V21 implements PCI 2.1 specification only - a 33 MHz, 32-bit parallel bus interface. It does not support PCI Express lanes, packet-based transaction layer, or serial differential signaling. Migration to PCIe requires a complete redesign using a modern controller such as the Infineon SLD8000 series or equivalent.
Can the four SCC channels operate at different protocols simultaneously?
Yes. Each SCC core is independently configurable via its own register set to run HDLC, PPP, SDLC, or transparent mode concurrently. The DSCC4 architecture guarantees full isolation: clock domains, FIFO pointers, interrupt vectors, and protocol state machines are physically separate per channel.
What is the maximum supported host bus clock frequency for the Local Bus Interface (LBI)?
The LBI supports up to 50 MHz operation in de-multiplexed mode with programmable wait states. Timing is validated per DS-1 section 13.2.2: tAVDV = 15 ns, tVLDV = 10 ns, and tRLDV = 20 ns - enabling reliable interfacing with high-speed DSPs like the TMS320C6000 family without external wait-state generators.
Is there hardware support for CRC-32 in PPP mode?
Yes. The SCC core performs full CRC-32 generation and verification in PPP bit-synchronous mode using the same polynomial (0x04C11DB7) defined in RFC 1662. CRC calculation occurs in real time during transmission/reception and is validated before frame acceptance or delivery to host memory.
