Product Overview
The S5920Q is AMCC’s 32‑bit PCI target bus controller. It bridges local add‑on buses to standard PCI buses, connecting MCUs, DSPs and custom logic to host systems. Supporting local bus speeds up to 40 MHz, it features pass‑through transfer architecture, dual 32‑byte burstable FIFOs and on‑chip mailbox registers. Packaged in 160‑pin PQFP, it is widely used for legacy expansion cards, industrial control boards and data acquisition hardware.
Core Advantages
Flexible Pass‑Through Architecture
Delivers high‑speed direct data transfers between PCI bus and local devices with low latency.
Simplified Local Bus Integration
Enables easy connection of external logic, MCUs and FPGAs to standard PCI host systems.
Integrated Mailbox & Status Registers
Built‑in mailbox and interrupt logic simplify host‑target messaging and status synchronization.
Proven Industrial Reliability
160‑pin PQFP surface‑mount package for stable deployment in industrial and legacy embedded platforms.

Frequently Asked Questions
Q1: What is the main function of S5920Q?
A: It is a 32‑bit PCI target bus controller. It connects local buses, FPGAs or DSPs to PCI host systems via pass‑through architecture.
Q2: What package does S5920Q use?
A: 160‑pin PQFP surface‑mount package.
Q3: Does S5920Q support PCI master mode?
A: No. It is target‑only, no bus master capability.
Q4: What is the difference between S5920Q and QS5920Q?
A: They are totally different chips. S5920Q is PCI controller; QS5920Q is RF device. They are not interchangeable.
Q5: What is the difference between S5920Q and S5920QRC?
A: S5920Q is SnPb lead‑based, RoHS non‑compliant. S5920QRC is RoHS‑compliant lead‑free version. Same die & pinout, only plating difference.
Q6: What are common alternative PCI target controllers?
A: PLX PCI9052, PCI9030. Note: These are pin‑incompatible; hardware and firmware modification is required for substitution.
Q7: What is the power supply requirement for S5920Q?
A: 5.0V core supply. I/O pins are 3.3V tolerant. Pure 3.3V core power is not supported.
Q8: What is the maximum local bus speed for S5920Q?
A: Up to 40 MHz. Supports 8‑bit / 16‑bit / 32‑bit width, independent of PCI clock.
Q9: Is S5920Q still in production?
A: No, it is obsolete (EOL). Only surplus / refurbished stock is available on market.
Q10: What is the difference between S5920 and S5920Q?
A: Same die, different packages. S5920 is PLCC‑68 socket package; S5920Q is 160‑PQFP SMD. Footprints cannot be swapped directly.
Q11: Does S5920Q support external BIOS?
A: Yes, optional external BIOS for custom PCI‑ROM firmware.
Q12: What does the suffix Q mean for S5920Q?
A: Suffix Q indicates 160‑pin PQFP surface‑mount package. No‑Q suffix refers to PLCC‑68 socket version.
