AMD XC4036XL-1BG432I

Overview

XC4036XL-1BG432I from Xilinx is a Field-Programmable Gate Array (FPGA) with 36,000 system gates, 432-ball BGA package, -1 speed grade (10 ns CLB delay), and I-grade industrial temperature range (-40°C to +100°C); used in high-reliability embedded control and interface bridging applications.

For engineers reviewing the XC4036XL-1BG432I datasheet, pinout, applications, or equivalent options, key selection criteria include CLB count, I/O voltage compatibility (3.3 V LVTTL/LVCMOS), configuration mode support (Master Serial, Slave Parallel), and JTAG boundary-scan compliance per IEEE 1149.1.

Technical Context

The XC4036XL-1BG432I implements a hierarchical architecture with Configurable Logic Blocks (CLBs), Input/Output Blocks (IOBs), and interconnect resources. It supports in-system reconfiguration via SelectMAP or serial PROM and includes dedicated carry logic for arithmetic functions.

Configuration is performed through JTAG, Master Serial, or Slave Parallel modes. The device uses SRAM-based configuration memory and requires external configuration PROM or processor-controlled loading for power-up initialization.

Key Specifications

Pinout & Package

XC4036XL-1BG432I is housed in a 432-ball Fine-Pitch Ball Grid Array (FBGA) package with 1.0 mm ball pitch, 27 × 27 array, and standard JEDEC MO-205AC footprint. Thermal pad on underside requires solder paste stencil design for reliable heat dissipation.

FAQ

What is the configuration voltage requirement for XC4036XL-1BG432I?

The XC4036XL-1BG432I requires 3.3 V for both core logic and I/O banks. It does not support 2.5 V or 1.8 V I/O standards. Configuration PROMs must deliver 3.3 V-compatible serial data, and all VCCO pins must be supplied at 3.3 V to ensure proper IOB operation and signal integrity. The XC4036XL-1BG432I datasheet specifies absolute maximum ratings and recommended operating conditions for each power domain.

Does XC4036XL-1BG432I support partial reconfiguration?

XC4036XL-1BG432I supports dynamic reconfiguration via Slave Parallel mode, allowing selected CLB columns to be reloaded while other logic remains operational. This capability is implemented using internal configuration access ports and requires external controller coordination. Full partial reconfiguration tools were not natively supported in early XC4000XL design flows, but hardware-level functionality is present in the XC4036XL-1BG432I silicon.

What JTAG instructions are supported by XC4036XL-1BG432I?

The XC4036XL-1BG432I implements IEEE 1149.1 JTAG instructions including SAMPLE/PRELOAD, EXTEST, INTEST, IDCODE, USERCODE, and BYPASS. It also supports CONFIG_IN and CONFIG_OUT for configuration bitstream access. These instructions enable boundary-scan testing, device identification, and in-circuit programming. The XC4036XL-1BG432I JTAG TAP controller is fully compliant with the standard and documented in Xilinx Application Note XAPP151.

Is XC4036XL-1BG432I RoHS compliant?

XC4036XL-1BG432I is not RoHS compliant. It contains lead in the solder balls of its 432-ball FBGA package and falls under the RoHS exemption for high-melting-temperature solders (Annex III, 7a). Xilinx documentation confirms Pb content in the BG432 package for this device family, and no lead-free variant was released for the XC4000XL series.

What is the maximum operating frequency of XC4036XL-1BG432I CLBs?

The XC4036XL-1BG432I -1 speed grade guarantees a maximum CLB propagation delay of 10 ns, corresponding to a theoretical maximum toggle rate of 100 MHz under ideal routing and loading conditions. Actual system clock frequencies depend on design topology, place-and-route results, and I/O timing constraints. Synthesis reports for XC4036XL-1BG432I designs typically achieve 60–85 MHz for register-to-register paths in typical implementations.
