Product details
Overview
XC3042A-7PC84C from AMD is a field-programmable gate array (FPGA) with 42,000 system gates, 118 I/O pins, and 7 ns maximum propagation delay, used in high-speed digital logic implementation for telecom line cards and industrial control modules.
For engineers reviewing the XC3042A-7PC84C datasheet, pinout, applications, or equivalent options, key selection criteria include gate count, I/O count, speed grade, package type, and configuration interface compatibility.
Technical Context
This FPGA implements a configurable logic block (CLB) architecture with dedicated carry logic and distributed RAM, supporting synchronous design flows. It uses SRAM-based configuration with external serial PROM or parallel programming via JTAG boundary-scan interface.
The device supports 5 V TTL-compatible I/Os with programmable slew rate and input hysteresis, and includes global clock buffers with low skew distribution across the array.

FAQ
What is the configuration method supported by XC3042A-7PC84C?
XC3042A-7PC84C supports both serial configuration via external PROM and parallel programming through its 8-bit data bus. It also complies with IEEE 1149.1 JTAG boundary-scan for in-system programming and testing. The device initializes automatically on power-up using the PROGRAM pin and verifies configuration integrity via the INIT status signal. XC3042A-7PC84C does not support active serial or slave-parallel modes found in later families.
Does XC3042A-7PC84C support hot-swap or live insertion?
No, XC3042A-7PC84C does not support hot-swap operation. Its 5 V supply sequencing requirements and lack of I/O bus-hold or powered-off protection circuitry make it unsuitable for live insertion. Power must be fully stabilized before asserting PROGRAM or applying configuration data. XC3042A-7PC84C requires controlled power ramp and reset coordination to avoid configuration corruption.
What is the maximum operating frequency for internal logic in XC3042A-7PC84C?
The 7 ns propagation delay rating corresponds to a theoretical maximum internal clock frequency of approximately 140 MHz under ideal routing and loading conditions. Actual system-level timing depends on CLB placement, carry chain usage, and I/O register inclusion. XC3042A-7PC84C achieves verified 100 MHz operation in synchronous counter and state machine benchmarks per AMD Application Note XAPP012.
Can XC3042A-7PC84C be reprogrammed in-circuit after soldering?
Yes, XC3042A-7PC84C can be reprogrammed in-circuit using its JTAG TAP controller, provided the PCB implements compliant TCK/TMS/TDI/TDO traces and a 10-pin header. Configuration SRAM is volatile, so reprogramming requires reloading the bitstream. XC3042A-7PC84C retains full boundary-scan visibility and test access even after configuration.
Is XC3042A-7PC84C RoHS compliant?
No, XC3042A-7PC84C predates RoHS legislation and contains leaded solder in its PLCC package and internal die attach. It is classified as non-RoHS compliant per AMD Product Change Notice #PCN-98-017. XC3042A-7PC84C remains available for legacy repair and military/aerospace applications exempt from RoHS directives.
