Product details
Overview
XC4052XLA-09HQ208C from Xilinx is a high-capacity, 3.3 V Field-Programmable Gate Array (FPGA) featuring 4,598 logic cells, 52,000 typical system gates, 61,952 RAM bits, 352 user I/Os, and support for up to 80 MHz synchronous system clock rates. It implements configurable logic blocks (CLBs) with edge-triggered dual-port RAM, dedicated carry logic, and eight global low-skew clock networks - deployed in PCI-compliant embedded control and data-path acceleration systems.
For engineers reviewing the XC4052XLA-09HQ208C datasheet, pinout, applications, or equivalent options, key selection criteria include its 0.35 µm SRAM process, 3.3 V core voltage with 5 V-tolerant I/Os, HQ208 ceramic quad flat pack package, and compatibility with XC4000X family bitstream tools and configuration modes.
Technical Context
The XC4052XLA-09HQ208C belongs to the XC4000XLA subfamily - a low-voltage, high-performance variant of the XC4000X series built on 0.35 µm SRAM technology. It supports Master Parallel, Slave Serial, and SelectMAP configuration modes, with internal configuration memory loaded via external PROM or microprocessor interface.
Its CLB architecture includes dual 4-input function generators (F/G), a third H-function generator with three inputs, two storage elements configurable as D-type flip-flops (XC4000XLA supports latches only in XC4000XV, not XLA), and programmable I/O buffers with individually controllable slew rate and pull-up/pull-down resistors. Input threshold is fixed at 1.6 V for 3.3 V CMOS/TTL compatibility.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Cells | 4,598 CLBs - determines maximum combinational logic density and routing resource allocation |
| Typical Gate Range | 33,000–100,000 gates - reflects usable logic capacity when mixing logic and RAM resources |
| User I/O Pins | 352 - defines maximum parallel interface width and board-level signal fan-out capability |
| On-Chip RAM Bits | 61,952 bits - enables embedded FIFOs, register files, and dual-port buffer implementation without external memory |
| System Clock Rate | Up to 80 MHz - specifies maximum synchronous operation frequency for timing-critical control paths |
| Core Voltage | 3.3 V ± 0.3 V - mandates compatible power delivery with tight regulation; I/Os tolerate 5 V inputs |
| Process Technology | 0.35 µm SRAM - defines transistor speed, static power consumption, and thermal profile |
Pinout & Package
XC4052XLA-09HQ208C is housed in a 208-pin Ceramic Quad Flat Pack (CQFP) package, designated HQ208. This hermetically sealed, leadless package provides high reliability for industrial and aerospace applications, with 0.5 mm lead pitch and symmetrical pin arrangement optimized for manual and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GCLK0–GCLK7 | Global Clock Inputs | Eight dedicated low-skew clock distribution networks - each drives all CLBs and IOBs with minimal skew for synchronous domain partitioning |
| IO_Lxx | Configurable I/O Banks | 352 bidirectional user pins grouped into banks - each supports independent VCCO (3.3 V), programmable pull-up/down, and slew-rate control |
| PROGRAM | Configuration Reset | Active-low asynchronous input that clears configuration memory and initiates reconfiguration sequence |
| DONE | Configuration Status | Open-drain output indicating successful configuration completion; used for system boot sequencing and FPGA readiness signaling |
| INIT | Initialization Status | Open-drain output active during configuration - asserts low if CRC error or PROM failure occurs |
| M0–M2 | Mode Selection | Three-pin strap to select configuration mode: Slave Serial, Master Serial, Master Parallel, or SelectMAP |
Key Features
| Feature | Design Value |
|---|---|
| SelectRAM™ Memory | Each CLB supports edge-triggered (synchronous) write and dual-port read/write - eliminates external SRAM for FIFOs and buffers |
| Dedicated Carry Logic | High-speed ripple-carry chain across CLBs - reduces arithmetic path delay by up to 50% vs. XC4000 |
| IEEE 1149.1 Boundary Scan | Full JTAG test access port integrated - enables board-level interconnect testing without physical probe points |
| 5 V-Tolerant I/Os | All user I/O pins accept 5 V inputs while operating at 3.3 V core - simplifies mixed-voltage system integration |
| Soft Start-up | Automatic slew-rate limiting on first output activation - prevents ground bounce during power-on initialization |

Equivalent & Alternatives
The following parts are listed as comparable options for similar FPGA-based logic implementation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XC4052XL-09HQ208C | Same logic capacity and pinout, but uses XC4000XL family architecture - lacks XLA-specific low-power optimizations and enhanced configuration security features | Acceptable for non-safety-critical commercial designs where power efficiency is secondary to cost | Select XC4052XL-09HQ208C only if legacy toolchain support for XC4000XL is required and XLA-specific features are unused |
| XC4062XL-09HQ208C | Higher capacity (5,472 CLBs, 62,000 gates), same HQ208 package - requires no PCB change but consumes more power and may need timing closure re-optimization | Suitable when future-proofing for feature expansion or higher gate utilization (>85%) in long-lifecycle programs | Choose XC4062XL-09HQ208C when additional logic headroom is needed for post-silicon firmware updates or added diagnostics logic |
Compared with XC4052XL-09HQ208C and XC4062XL-09HQ208C, the XC4052XLA-09HQ208C delivers optimized static power reduction and improved configuration integrity for mission-critical deployments - making it preferable where thermal management and field reliability outweigh raw gate count.

FAQ
What is the maximum supported configuration mode for XC4052XLA-09HQ208C?
The XC4052XLA-09HQ208C supports Master Parallel, Slave Serial, and SelectMAP configuration modes. Master Parallel mode uses up to 22 address bits for large PROM addressing, while Slave Serial relies on external serial PROM with mode pins M0–M2 set to 001. All modes retain full boundary scan (JTAG) access for debug and verification.
Does XC4052XLA-09HQ208C support dual-port RAM functionality?
Yes, XC4052XLA-09HQ208C supports dual-port RAM in each CLB: two 16x1 function generators can be jointly configured as a 16x1 dual-port RAM with independent read and write ports. This enables simultaneous read/write operations at the same or different addresses - critical for FIFO and buffer applications without external memory.
Is XC4052XLA-09HQ208C pin-compatible with other XC4000X devices?
XC4052XLA-09HQ208C is pinout-compatible with XC4052XL-09HQ208C and XC4062XL-09HQ208C in the same HQ208 package. However, it is not bitstream-compatible with XC4000E or XC4000 families. Pin compatibility enables mechanical interchangeability but requires re-synthesis and place-and-route for functional equivalence.
What is the input voltage threshold specification for XC4052XLA-09HQ208C I/Os?
The XC4052XLA-09HQ208C has a fixed input threshold of 1.6 V, compatible with both 3.3 V CMOS and TTL logic levels. Unlike earlier XC4000 families, this threshold is not globally configurable - it is inherent to the XC4000XLA process and ensures robust noise immunity in mixed-signal environments.
Can XC4052XLA-09HQ208C be used in new designs given its obsolescence status?
Although marked "Product Obsolete or Under Obsolescence" per Xilinx documentation dated May 1999, XC4052XLA-09HQ208C remains available through Aetrix Electronics with traceable, tested inventory for legacy system sustainment. Its use is appropriate for repair, replacement, and long-cycle industrial programs where requalification timelines prohibit migration to newer architectures.
