AMD XC4052XLA-09HQ208I

Overview

XC4052XLA-09HQ208I from Xilinx is a high-capacity, 3.3 V Field-Programmable Gate Array (FPGA) featuring 4,598 logic cells, 52,000 typical gates, and 61,952 on-chip RAM bits. It supports synchronous system clock rates up to 80 MHz, includes eight global low-skew clock networks, and delivers PCI compliance for -2 and faster speed grades. It is used in legacy embedded control, industrial interface bridging, and reconfigurable digital signal processing subsystems.

For engineers reviewing the XC4052XLA-09HQ208I datasheet, pinout, applications, or equivalent options, key selection criteria include confirmed CLB count (1,936), I/O count (352), 0.35 µm SRAM process node, HQ208 ceramic PGA package, and support for edge-triggered dual-port RAM per CLB - all critical for timing-critical FPGA migration and long-life industrial design continuity.

Technical Context

The XC4052XLA-09HQ208I belongs to the XC4000XLA family - a low-voltage, high-performance variant of the XC4000X series built on 0.35 µm SRAM technology. Its architecture features configurable logic blocks (CLBs) with three function generators (F/G/H), dual flip-flops or latches per CLB, and dedicated carry logic enabling >150 MHz internal performance.

It implements hierarchical interconnect with enhanced routing capacity versus XC4000E, including 22 additional vertical and 12 horizontal lines per CLB row/column, plus early-clock capture latches in IOBs for precise input synchronization. The device supports master/slave serial and byte-parallel configuration modes with 22-bit addressing in Master Parallel mode.

Key Specifications

Pinout & Package

FAQ

What is the maximum system clock frequency supported by XC4052XLA-09HQ208I?

The XC4052XLA-09HQ208I supports synchronous system clock rates up to 80 MHz, verified for -2 speed grade operation. This rating applies to fully constrained, place-and-routed designs meeting setup/hold timing across worst-case voltage and temperature corners. Internal paths can exceed 150 MHz, but system-level performance depends on I/O timing, clock distribution skew, and PCB layout integrity. The XC4052XLA-09HQ208I achieves this via dedicated early-clock buffers and low-skew global networks.

Is XC4052XLA-09HQ208I pin-compatible with other XC4000X devices?

Yes - XC4052XLA-09HQ208I is pinout-compatible with XC4052XL-09HQ208I and XC4052EX-09HQ208I, sharing identical 208-pin HQ208 ceramic PGA mechanical and electrical pin mapping. However, it is not bitstream-compatible with XC4000 or XC4000E families due to architectural enhancements including expanded routing, latch-capable CLBs, and updated configuration logic. The XC4052XLA-09HQ208I retains backward compatibility only at the physical layer.

Does XC4052XLA-09HQ208I support JTAG boundary scan?

Yes, XC4052XLA-09HQ208I integrates IEEE 1149.1-compliant boundary scan logic with dedicated TCK, TMS, TDI, and TDO pins. This enables in-system programming, interconnect testing, and visibility into internal register states during debug. The boundary scan chain covers all user I/Os and major internal nodes, and is accessible via standard JTAG controllers without requiring external programming hardware beyond a compliant adapter. Configuration and readback operations also leverage this infrastructure.

Can XC4052XLA-09HQ208I be configured using serial PROMs?

Yes, XC4052XLA-09HQ208I supports Master Serial configuration mode, where it actively clocks data from a standard 3.3 V serial PROM (e.g., Xilinx XC18V00 series). The device drives the PROM's clock and reads configuration bits synchronously. Mode pins (M0–M2) must be set to '101' for Master Serial operation. This method requires no external controller and enables autonomous power-on initialization - a key feature for unattended industrial systems relying on the XC4052XLA-09HQ208I.

What type of RAM functionality does XC4052XLA-09HQ208I provide in its CLBs?

XC4052XLA-09HQ208I supports three RAM configurations per CLB: 16x1 single-port (level-sensitive or edge-triggered), 32x1 single-port, and 16x1 dual-port (edge-triggered only). Each CLB's F and G function generators act as 16-bit look-up tables that can be repurposed as RAM. Dual-port mode enables simultaneous read and write to independent addresses - essential for FIFOs and ping-pong buffering. All RAM is synchronous, initialized at configuration time, and retains data only while powered. The XC4052XLA-09HQ208I delivers 61,952 total RAM bits across 1,936 CLBs.
