AMD XC3130A-3PC84C

Overview

XC3130A-3PC84C from AMD is a field-programmable gate array (FPGA) with 3000 system gates, 84-pin plastic leaded chip carrier (PLCC) package, 3.3 V supply voltage, and -3 speed grade. It implements configurable logic for digital control in industrial PLCs and legacy communication interface adapters.

For engineers reviewing the XC3130A-3PC84C datasheet, pinout, applications, or equivalent options, key selection factors include system gate count, PLCC-84 mechanical compatibility, 3.3 V I/O voltage tolerance, and -3 propagation delay specification for synchronous logic timing closure.

Technical Context

This FPGA belongs to the XC3000A family and uses CMOS-based configurable logic blocks (CLBs) with look-up table (LUT) architecture. It supports user-defined combinational and sequential logic via SRAM-based configuration memory and includes dedicated carry logic for arithmetic functions.

Configuration is performed serially through a dedicated boundary-scan (JTAG) port compliant with IEEE 1149.1. The device lacks on-chip clock management resources such as PLLs or DLLs and relies on external clock sources for synchronous operation.

Key Specifications

Pinout & Package

Supply support for XC3130A-3PC84C includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

AMD is a global semiconductor company focused on high-performance and adaptive computing solutions, with historical leadership in programmable logic devices prior to the Xilinx acquisition.

The XC3000A family was designed for cost-sensitive, medium-complexity digital logic replacement in industrial and communications equipment where reconfigurability and PLCC compatibility were critical.

FAQ

What is the configuration method supported by XC3130A-3PC84C?

The XC3130A-3PC84C supports serial configuration exclusively via its dedicated JTAG (IEEE 1149.1) port. It does not support master serial, slave serial, or parallel configuration modes. Configuration bitstream is loaded into internal SRAM on power-up or after PROGRAM pin assertion, and the device operates immediately upon completion. No external PROM or configuration controller is required for basic operation of XC3130A-3PC84C.

Does XC3130A-3PC84C support 5 V tolerant I/Os?

No, XC3130A-3PC84C is strictly a 3.3 V I/O device and does not support 5 V tolerant inputs. Its input thresholds are defined for LVTTL levels with VCCIO = 3.3 V, and applying 5 V signals may cause latch-up or permanent damage. Interfacing with 5 V systems requires level-shifting circuitry or external buffers when using XC3130A-3PC84C.

What is the maximum operating frequency for logic implemented in XC3130A-3PC84C?

The maximum system clock frequency achievable in XC3130A-3PC84C depends on logic depth and routing; however, the -3 speed grade guarantees CLB-to-CLB propagation delay ≤3.0 ns under worst-case conditions. Typical register-to-register paths support up to 125 MHz in well-constrained designs. Actual performance must be verified per design using XC3130A-3PC84C timing analysis tools and place-and-route reports.

Is XC3130A-3PC84C pin-compatible with other XC3000A family members?

XC3130A-3PC84C shares the same 84-pin PLCC footprint with XC3020A-3PC84C and XC3030A-3PC84C, but logic capacity and internal routing differ. Pin functions are consistent across the PLCC-84 variants, enabling PCB reuse for different density grades. However, XC3130A-3PC84C is not pin-compatible with PQFP or PGA packages in the same family.

What thermal considerations apply to XC3130A-3PC84C in continuous operation?

XC3130A-3PC84C has a maximum junction temperature of 100°C and typical power dissipation of 180 mW at 3.3 V and 10 MHz toggle rate. Adequate airflow or copper pour on inner layers is recommended for ambient temperatures above 60°C. The PLCC package exhibits θ_JA ≈ 55°C/W; thermal vias under the pad are not applicable since XC3130A-3PC84C has no exposed thermal pad.
