Product details
Overview
SAF82532N10V32A from Siemens AG is an Enhanced Serial Communication Controller (ESCC2) IC supporting HDLC/SDLC, asynchronous, and BISYNC serial protocols with dual-channel operation, 64-byte FIFOs per channel, and selectable out-of-band flow control in ASYNC mode. It integrates a programmable baud rate generator with enhanced resolution, DPLL-based clock recovery, and DMA-capable parallel microprocessor interface for Intel 80x86 and Motorola 68k families.
For engineers reviewing the SAF82532N10V32A datasheet, SAF82532N10V32A pinout, SAF82532N10V32A application, or SAF82532N10V32A equivalent, key selection criteria include dual-channel HDLC framing support, 80-pin MQFP package compatibility, V3.2 firmware feature set (e.g., extended TIMR register, RSTA/ISR0 interrupt enhancements), and ESCC2 system integration with SAB 80188/80286/68000-series processors.
Technical Context
The SAF82532N10V32A implements two independent serial channels sharing a common 16-bit parallel bus interface, each with dedicated 64-byte transmit/receive FIFOs, CRC-16/CRC-32 engines, and configurable HDLC flag detection. Its DPLL supports clock recovery from NRZ-encoded streams at up to 2.048 Mbps per channel.
It supports three operational modes-HDLC/SDLC, asynchronous, and BISYNC-with mode-specific register sets (CCR4 introduced in V3.x for ASYNC/BISYNC), selectable in-band/out-of-band flow control, and programmable timer registers (TIMR) enabling precise timing for protocol timeouts and frame intervals.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Serial Protocols | HDLC/SDLC, Asynchronous (ASYNC), BISYNC - enables interoperability with legacy telecom, industrial control, and point-of-sale systems. |
| FIFO Depth | 64 bytes per channel - reduces CPU interrupt overhead and supports burst data transfers without loss. |
| Max Data Rate | 2.048 Mbps per channel - sufficient for E1/T1 line interface and high-speed modem applications. |
| Baud Rate Generator | Enhanced resolution BRG (V3.x) - allows fine-grained baud rate tuning with ±0.1% accuracy over wide frequency ranges. |
| Microprocessor Interface | 16-bit parallel bus, Intel/Motorola mode select - direct connection to SAB 80188, 80286, 68000-series CPUs without glue logic. |
| Clock Recovery | Digital Phase-Locked Loop (DPLL) - recovers synchronous clock from incoming serial stream, eliminating external clock source dependency. |
| Package | P-MQFP-80 (Plastic Metric Quad Flat Package, 80 pins) - surface-mount compatible with standard reflow profiles and IPC-7351B footprint. |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AD0–AD15 | Address/Data Multiplexed Bus | Bi-directional 16-bit bus for register access and data transfer; time-multiplexed address/data in Intel mode. |
| RD, WR, CS0, CS1 | Control Signals | Read/write strobes and chip selects for memory-mapped I/O interfacing with host CPU. |
| TxD0, TxD1 | Transmit Data Outputs | Differential or single-ended serial outputs per channel; configured via MODE register for NRZ/NRZI encoding. |
| RxD0, RxD1 | Receive Data Inputs | Serial inputs with integrated DPLL clock recovery; support both synchronous and asynchronous reception. |
| RTS0/1, CTS0/1, CD0/1 | Modem Control | Hardware handshaking signals per channel; RTS/CTS enable flow control, CD monitors carrier presence. |
| CLK, XTAL1, XTAL2 | Timing Inputs | External clock input or crystal oscillator connection; supports 1–20 MHz crystal for internal timing generation. |
| INT0, INT1 | Interrupt Outputs | Open-drain interrupt requests per channel; level-sensitive, maskable via ISR0/ISR1 registers. |
| RESET | Asynchronous Reset | Active-low global reset that clears all registers and resets FIFOs and state machines. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent serial channels | Enables simultaneous HDLC and ASYNC communication on one die - reduces board space and inter-chip latency in multi-protocol gateways. |
| Selectably enhanced BRG resolution (V3.2) | Supports non-standard baud rates (e.g., 1.8432 Mbps) with <±0.1% error - critical for custom telecom framing and legacy terminal emulation. |
| Extended TIMR register functionality | Configurable 16-bit timer with reload and interrupt capability - used for HDLC keep-alive timeout, ASYNC break detection, and protocol-level watchdogs. |
| Out-of-band flow control (V3.x) | Hardware RTS/CTS assertion per channel - eliminates XON/XOFF byte interference in binary data streams (e.g., firmware updates, encrypted payloads). |
| Shared flags and cyclic transmission mode | Enables continuous HDLC flag transmission during idle periods - maintains link synchronization in leased-line applications without requiring external clock sources. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial communication controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Z85230 | Single-channel ESCC with 32-byte FIFOs; no DPLL; supports only HDLC/ASYNC (no BISYNC). | Limited to point-to-point HDLC links; unsuitable for multi-protocol gateways requiring BISYNC legacy support. | Select when cost sensitivity outweighs dual-channel and BISYNC requirements. |
| SCC68070 | Motorola-native 16-bit SCC; 16-byte FIFOs; no enhanced BRG or V3.x TIMR extensions. | Requires external clock recovery circuitry; lacks selectable out-of-band flow control and extended register set. | Prefer for existing 68k-based designs where software compatibility with legacy SCC drivers is mandatory. |
Compared with Z85230 and SCC68070, SAF82532N10V32A uniquely delivers dual-channel HDLC/ASYNC/BISYNC convergence, DPLL clock recovery, and V3.2 firmware features - making it the only option for new designs requiring mixed-protocol, clock-autonomous serial infrastructure in telecom and industrial edge nodes.

FAQ
What microprocessor buses does SAF82532N10V32A support?
The SAF82532N10V32A supports both Intel-style (80x86) and Motorola-style (68k) parallel bus interfaces via mode-select pins. It operates in multiplexed AD0–AD15 mode with RD/WR/CS controls, and is verified for direct interfacing with SAB 80188, 80286, MC68000, and MC68020 processors per the 07.96 User's Manual.
Does SAF82532N10V32A support automatic clock recovery from serial data?
Yes - it integrates a Digital Phase-Locked Loop (DPLL) that recovers synchronous clock signals directly from NRZ-encoded HDLC/SDLC streams at rates up to 2.048 Mbps per channel. This eliminates the need for external clock sources or separate clock recovery ICs in line-interface applications.
What is the function of the CCR4 register introduced in V3.2?
The Channel Configuration Register 4 (CCR4) was added in V3.2 to extend ASYNC and BISYNC mode configuration, enabling selective activation of enhanced features including in-band flow control transparency, extended break detection, and DMA-triggered transmit start conditions - not available in earlier revisions.
Is SAF82532N10V32A RoHS-compliant?
No - SAF82532N10V32A was manufactured prior to RoHS Directive 2002/95/EC implementation and contains leaded solder terminations and Pb-in-glass frit in the ceramic packaging. It is intended for legacy repair, military, or industrial applications exempt from RoHS compliance requirements.
