Product details
Overview
XC3020A-7PC84C from AMD is a field-programmable gate array (FPGA) with 2,000 usable gates, 84-pin plastic leaded chip carrier (PLCC) package, 7 ns propagation delay, and 5 V single-supply operation. It serves as a reconfigurable logic fabric in digital control systems for industrial motion controllers.
For engineers reviewing the XC3020A-7PC84C datasheet, pinout, applications, or equivalent options, key selection criteria include gate count, speed grade, I/O count, power supply requirements, and PLCC-84 mechanical compatibility.
Technical Context
This FPGA implements configurable logic blocks (CLBs) and interconnect resources using static RAM-based configuration memory. It supports synchronous design with dedicated clock buffers and global routing resources for timing-critical paths.
Configuration is performed via parallel mode using an external PROM or microcontroller. The device lacks on-chip configuration memory and requires external initialization at power-up.

FAQ
What is the configuration method for XC3020A-7PC84C?
The XC3020A-7PC84C uses parallel mode configuration via an external PROM or microcontroller. It has no on-chip nonvolatile memory, so configuration data must be loaded each power-on cycle. The PROGRAM and INIT pins manage initialization sequence timing and status reporting during this process. XC3020A-7PC84C does not support serial or JTAG configuration modes.
Does XC3020A-7PC84C support mixed-voltage I/O operation?
No, XC3020A-7PC84C operates exclusively from a single 5.0 V ±5% supply and all I/Os are TTL/CMOS-compatible at that voltage. It lacks internal voltage translators or multi-voltage I/O banks. XC3020A-7PC84C requires external level-shifting circuitry to interface with 3.3 V or 2.5 V devices.
What is the maximum operating frequency for XC3020A-7PC84C clock inputs?
The XC3020A-7PC84C supports a maximum system clock frequency of 20 MHz based on its 7 ns propagation delay specification and internal routing delays. This limit applies to the dedicated CLK input driving global clock networks. XC3020A-7PC84C does not specify higher-frequency operation in official timing models.
Is XC3020A-7PC84C RoHS compliant?
No, XC3020A-7PC84C predates RoHS legislation and contains leaded solder in its PLCC package and lead frame. It is classified as non-RoHS-compliant and intended for legacy repair, military, or industrial applications exempt from modern environmental directives. XC3020A-7PC84C documentation does not list Pb-free variants.
Can XC3020A-7PC84C be reprogrammed in-system?
XC3020A-7PC84C supports in-system reprogramming only if the host system provides full parallel configuration access, including PROGRAM, INIT, and data bus control. It lacks dedicated ISP circuitry or JTAG boundary-scan, so reprogramming requires external hardware support. XC3020A-7PC84C does not enable hot-swap or partial reconfiguration.
