Product details
Overview
SAB82532H10V32A from Siemens AG is an Enhanced Serial Communication Controller (ESCC2) IC designed for high-reliability HDLC/SDLC, asynchronous, and BISYNC serial protocol handling in embedded telecom and industrial control systems. It supports dual-channel operation, 64-byte transmit/receive FIFOs per channel, selectable enhanced-resolution baud rate generator (BRG), and hardware flow control with XON/XOFF and out-of-band RTS/CTS. Used in legacy base station controllers interfacing with SAB 80188 or MC 68000 microprocessors.
For engineers reviewing the SAB82532H10V32A datasheet, SAB82532H10V32A pinout, SAB82532H10V32A application, or SAB82532H10V32A equivalent, key selection criteria include dual-channel HDLC framing support, DPLL-based clock recovery, programmable interrupt priority, DMA interface compatibility, and P-MQFP-80 package integration with 80-pin footprint.
Technical Context
The SAB82532H10V32A implements a dual-channel, multi-protocol serial controller with independent HDLC/SDLC, ASYNC, and BISYNC mode support per channel. Each channel features CRC-32 generation/checking, automatic flag insertion/deletion, bit-stuffing, and receive address filtering - all configurable via dedicated status/control registers including CCR4, TIMR, and RFC.
It integrates a Digital Phase-Locked Loop (DPLL) for clock recovery in synchronous modes, supports both Siemens/Intel and Motorola bus timing protocols, and provides full interrupt cascading capability for multi-processor systems. The V3.2 revision adds selectable enhanced BRG resolution, extended RSTA/ISR0 register functionality, and new RFIFO control bits (DXS) for ASYNC mode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Protocol Support | Dual-channel HDLC/SDLC, ASYNC, and BISYNC - enables simultaneous point-to-point and multipoint link layer processing in telecom infrastructure. |
| FIFO Depth | 64 bytes TX/RX per channel - reduces CPU overhead by minimizing interrupt frequency during burst data transfers. |
| Baud Rate Generator | Selectably enhanced resolution BRG - allows precise timing alignment with legacy T1/E1 line rates and custom serial clocks. |
| Interrupt Architecture | Programmable priority levels and cascading support - ensures deterministic response in real-time multi-peripheral systems. |
| DMA Interface | Direct memory access support with ADMA compatibility - offloads large-frame transfers from host CPU without polling. |
| Clock Recovery | Integrated DPLL with ±1.5% lock range - eliminates external clock synthesizers for synchronous line interfaces. |
| Flow Control | XON/XOFF (in-band), RTS/CTS (out-of-band), and DXS-controlled RFIFO - enables robust handshaking across noisy industrial RS-232/422 links. |
Pinout & Package
Package: P-MQFP-80 (Plastic Metric Quad Flat Package, 80 pins, 0.65 mm pitch, 12 mm × 12 mm body).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLK | Master Clock Input | Accepts 1–20 MHz crystal or external clock; drives internal DPLL and BRG for all serial channels. |
| XTAL1/XTAL2 | Crystal Oscillator Terminals | Supports fundamental-mode quartz crystals up to 20 MHz; internal oscillator circuitry enables standalone clock source. |
| RD/WR | Read/Write Control | Active-low strobes for Siemens/Intel bus mode; defines data transfer direction on shared data bus. |
| CS0/CS1 | Chip Select Inputs | Enable decoding of ESCC2 register space within 64 KB I/O map; supports dual-device addressing. |
| INT0/INT1 | Channel Interrupt Outputs | Open-drain, active-low signals indicating channel-specific events (RX ready, TX empty, error flags). |
| RxD0/TxD0 | Channel 0 Serial I/O | Differential or single-ended RX/TX lines supporting RS-232/422 physical layer with external transceivers. |
| RxD1/TxD1 | Channel 1 Serial I/O | Independent second serial port with identical electrical characteristics and protocol stack as Channel 0. |
| RTS0/CTS0 | Channel 0 Flow Control | Hardware handshaking pair enabling automatic transmitter enable/disable based on receiver buffer status. |
Key Features
| Feature | Design Value |
|---|---|
| Dual Independent Channels | Each channel operates autonomously in HDLC, ASYNC, or BISYNC mode with separate FIFOs, registers, and interrupts. |
| CRC-32 Engine | Hardware-accelerated frame checksum generation and verification per channel - eliminates software CRC overhead. |
| Programmable BRG Resolution | V3.2-enhanced BRG supports 16-bit divisor with fractional adjustment - achieves <±0.1% baud error at 19.2 kbps. |
| Receive Address Filtering | Configurable 8-bit address match logic with mask register - enables selective frame acceptance in multi-drop networks. |
| Extended Transparent Mode | Full 8-bit byte transparency with zero-bit insertion suppression - preserves binary payload integrity in modem/data-fax applications. |

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 |
|---|---|---|---|
| Z8536 | Single-channel Zilog ESCC; no DPLL; 32-byte FIFO; older BRG architecture. | Limited to point-to-point HDLC only; lacks ASYNC/BISYNC flexibility and dual-port concurrency. | Choose when cost sensitivity outweighs channel count and clock recovery needs. |
| SCC68070 | Motorola 68k-compatible serial controller; 16-byte FIFO; no CRC-32; software-managed flow control. | Requires tight coupling with 68000 CPU; no autonomous HDLC framing; higher CPU load for protocol handling. | Prefer only in legacy 68k-based designs where peripheral compatibility is mandatory. |
Compared with Z8536 and SCC68070, the SAB82532H10V32A delivers superior integration through dual-channel independence, hardware CRC-32, DPLL clock recovery, and V3.2-enhanced BRG - making it uniquely suited for space-constrained, multi-protocol telecom edge nodes.

FAQ
What bus interface standards does the SAB82532H10V32A support?
The SAB82532H10V32A natively supports both Siemens/Intel-style and Motorola-style parallel bus timing protocols. It uses CS0/CS1, RD/WR, and address lines A0–A5 to decode its 64-register map, with timing compliant to Intel 8086/80188 and Motorola 68000 specifications as verified in Section 11.4.1 of the V3.2 User's Manual.
Does the SAB82532H10V32A support automatic HDLC flag detection and bit-stuffing?
Yes - the device performs fully autonomous HDLC frame processing including flag (0x7E) detection, zero-bit insertion/deletion, CRC-32 generation and checking, and address field filtering. These functions are implemented in hardware and require no CPU intervention during normal frame transmission or reception.
Can the SAB82532H10V32A operate with a single external crystal for both channels?
Yes - the CLK input accepts a single master clock (1–20 MHz), and XTAL1/XTAL2 terminals support direct connection of a fundamental-mode quartz crystal. Both channels derive timing from this common source, and the integrated DPLL allows synchronous mode operation without requiring two independent clock sources.
Is the SAB82532H10V32A RoHS-compliant or lead-free?
No - the SAB82532H10V32A is a legacy 1996-era component manufactured prior to RoHS legislation. Its packaging contains leaded solder finish and halogenated materials, as confirmed in the original Siemens safety notice stating "components may contain dangerous substances." It is intended for repair, legacy replacement, or non-consumer industrial use only.
