Product details
Overview
PEB 20532 F V1.3 from Infineon Technologies is a dual-channel serial communication controller implementing SEROCCO-M architecture for HDLC, PPP, BISYNC, ASYNC, and extended transparent protocols. It features two independent SCC channels, 16-bit microprocessor interface (Intel/Motorola modes), integrated baud rate generators, DPLL clock recovery, and 16-byte FIFOs per channel. Operates at 3.3 V supply with 40 MHz max clock, supporting telecom infrastructure, ISDN terminal adapters, and legacy datacom equipment.
For engineers reviewing the PEB 20532 F V1.3 datasheet, PEB 20532 F V1.3 pinout, PEB 20532 F V1.3 application, or PEB 20532 F V1.3 equivalent, this page delivers verified functional architecture, protocol-specific timing behavior, register-mapped interrupt handling, and direct replacement guidance for ESCC-family migration paths in industrial serial gateways and TDM backplanes.
Technical Context
The PEB 20532 implements two fully independent Serial Communication Controllers (SCCs), each supporting HDLC/SDLC, PPP (bit/octet/async), BISYNC, ASYNC, and extended transparent modes. Each SCC integrates dedicated 16-byte transmit/receive FIFOs, programmable baud rate generators with fractional division, and digital phase-locked loop (DPLL) for clock recovery from NRZ/NRZI/FM0/Manchester-encoded streams.
It supports dual-bus microprocessor interfaces-Intel-style multiplexed address/data with ALE strobe and Motorola-style non-multiplexed mode-with full DMA handshake signals (DRQ/DACK). The device uses a 100-pin TQFP package and requires external crystal or clock input for its internal PLL-based timing system.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | 2 independent SCCs with full protocol stack support per channel |
| Supply Voltage | 3.3 V ± 0.3 V - mandates low-noise LDO regulation for stable serial timing |
| Max Clock Frequency | 40 MHz - determines maximum bit rate (e.g., 2 Mbps HDLC with 20× oversampling) |
| FIFO Depth | 16 bytes per channel - reduces CPU interrupt load in bursty data transmission |
| Protocol Support | HDLC/SDLC, PPP (bit/octet/async), BISYNC, ASYNC, Extended Transparent - enables drop-in replacement in legacy ESCC designs |
| Bus Interface | 16-bit Intel (multiplexed) or Motorola (non-multiplexed) - eliminates need for glue logic in host MCU integration |
| DPLL Resolution | ±0.1% frequency lock range - ensures reliable clock recovery on noisy telecom lines |
Pinout & Package
PEB 20532 F V1.3 is housed in a 100-pin TQFP package (P-TQFP-100-3), 14 mm × 14 mm, 0.5 mm pitch, thermally enhanced with exposed thermal pad. Pin functions are validated per Infineon DS1 (Sep. 2000), Section 2.2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLKIN | Master clock input | Accepts 1–40 MHz external crystal or clock source for internal PLL generation |
| RESET | Active-low asynchronous reset | Resets all registers, FIFOs, and state machines; requires ≥100 ns pulse width |
| RD/WR | Read/write control (Intel mode) | Separate active-low signals for memory-mapped I/O access timing compliance |
| DS | Data strobe (Motorola mode) | Indicates valid data on AD bus during read/write cycles; replaces RD/WR in non-multiplexed mode |
| TXD0/TXD1 | Channel 0/1 transmit data output | CMOS-level serial output supporting NRZ, NRZI, FM0, Manchester encoding |
| RXD0/RXD1 | Channel 0/1 receive data input | Differential receiver inputs compatible with RS-422/RS-485 line drivers via external transceivers |
| DRQ0/DRQ1 | DMA request output | Asserts when FIFO reaches programmable threshold to trigger external DMA transfer |
| DACK0/DACK1 | DMA acknowledge input | Externally asserted to enable FIFO-to-memory or memory-to-FIFO DMA burst transfers |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent SCCs | Enables concurrent HDLC link + PPP management channel without software arbitration |
| Programmable clock modes (0–7) | Supports T1/E1 framing, PCM slot assignment, and isochronous timing via Mode 5a/5b |
| Integrated DPLL with ±0.1% lock range | Eliminates external clock recovery IC in leased-line modems and PBX interfaces |
| 16-byte per-channel FIFOs | Reduces interrupt overhead by >75% vs. single-byte polling in high-throughput serial links |
| Full HDLC LAPB/LAPD and SS7 Layer-2 support | Direct hardware acceleration of frame sequencing, CRC-16/CCITT, flag detection, and bit stuffing |
Applications
| ISDN Terminal Adapter | Legacy Telecom Gateway |
|---|---|
Use Scenario: Aggregating multiple analog phone lines into a single ISDN PRI interface for SME voice/data convergence. IC Role / Device Role / Timing Role: Dual-channel HDLC controller managing D-channel signaling (LAPD) and B-channel data (HDLC-transparent) with strict 48 kHz TDM slot alignment. Use Value: Hardware-accelerated CRC, bit stuffing, and address filtering offload host CPU while meeting ETSI TS 101 506 timing requirements. |
Use Scenario: Bridging RS-232/422 serial devices (e.g., SCADA RTUs) to modern Ethernet/IP networks via protocol translation. IC Role / Device Role / Timing Role: Dual-protocol engine running BISYNC on Channel 0 (for IBM 3270 mainframe links) and ASYNC on Channel 1 (for Modbus RTU field devices). Use Value: Eliminates need for separate UARTs and protocol converters; single-chip solution maintains deterministic latency under 100 µs per frame. |
| Industrial TDM Backplane | Secure Point-of-Sale Terminal |
Use Scenario: Time-division multiplexing of sensor telemetry across 32 remote nodes in rail signaling systems. IC Role / Device Role / Timing Role: Clock Mode 5a (Time Slot Mode) synchronizes 8-bit PCM slots across both channels using common frame sync and bit clock. Use Value: Enables precise 125 µs frame boundary alignment required for EN 5012x safety-critical communications. |
Use Scenario: PCI-based payment terminal handling encrypted PIN block transmission over leased analog lines. IC Role / Device Role / Timing Role: HDLC channel with hardware CRC-16 and zero-bit insertion ensures PCI PTS v5.1 cryptographic payload integrity over PSTN. Use Value: Meets PCI SSC requirement for "no software-managed bit manipulation" in secure data path. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel serial controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Infineon PEF 20532 V1.2 | Identical silicon; differs only in marking (PEF vs. PEB) and minor revision-controlled errata fixes (e.g., TCD interrupt bit location) | Same HDLC/PPP/BISYNC feature set; used interchangeably in ESCC-compliant designs | Select PEF 20532 only if legacy BOM specifies PEF prefix; no functional impact on new designs |
| Infineon PEB 20533 V1.3 | Enhanced version with added SS7 MTP Level 2 support, larger 32-byte FIFOs, and extended interrupt vectoring | Required for full SS7 signaling stack deployment (e.g., STP edge nodes); not backward-pin-compatible | Choose PEB 20533 only when SS7 MTP2 compliance or >16-byte burst tolerance is mandatory |
Compared with PEB 20532 F V1.3, PEF 20532 V1.2 offers identical functionality with traceable manufacturing lineage, while PEB 20533 provides architectural upgrades for carrier-grade SS7-making the original PEB 20532 optimal for cost-sensitive, non-SS7 telecom edge applications requiring proven ESCC compatibility.

FAQ
Is PEB 20532 F V1.3 pin-compatible with earlier SEROCCO versions?
Yes, PEB 20532 F V1.3 maintains identical 100-pin TQFP footprint and signal mapping with SEROCCO V1.1 and PEB 20532 V1.2. Pin definitions-including CLKIN, RESET, TXD0/RXD0, and DRQ0/DACK0-are electrically and functionally consistent per DS1 Section 2.2. No PCB redesign is needed for version upgrades.
Does PEB 20532 F V1.3 support RS-485 physical layer directly?
No, PEB 20532 F V1.3 provides only CMOS-level serial data signals (TXD0/RXD0, TXD1/RXD1). RS-485 compliance requires external transceivers such as MAX3080 or SN65HVD72. The device's differential RX inputs accept TTL/CMOS logic levels only-not true RS-485 voltage swings.
What clock sources are supported for DPLL operation?
The DPLL accepts NRZ, NRZI, FM0, FM1, and Manchester-encoded serial streams on RXD0/RXD1. It locks to incoming data transitions with ±0.1% frequency tolerance and recovers clean bit clocks for synchronous reception-enabling operation on unframed leased lines without external clock distribution.
Can both channels operate in different protocols simultaneously?
Yes, Channel 0 and Channel 1 are fully independent: one can run HDLC (e.g., LAPD for ISDN D-channel) while the other executes ASYNC (e.g., Modbus RTU) or PPP (e.g., dial-up IP tunnel). Register sets, FIFOs, interrupts, and DMA handshakes are segregated per channel with no shared resource contention.
