Product details
Overview
XC3142-3TQ100C from Xilinx is a high-performance Field Programmable Gate Array (FPGA) with 3,000 logic gates, 144 Configurable Logic Blocks (12 × 12 array), 96 user I/Os, and guaranteed 1.55–4.1 ns logic delays. It operates at 3.3 V, supports TTL/CMOS input thresholds, and integrates full-system logic in a single TQFP-100 package for embedded control and digital signal routing.
For engineers reviewing the XC3142-3TQ100C datasheet, pinout, applications, or equivalent options, key selection criteria include its 3.3 V operation, 96-user-I/O count, 12×12 CLB architecture, Soft Startup slew-rate limiting, and bitstream compatibility with XC3000A/L and XC3100A families.
Technical Context
The XC3142-3TQ100C implements a static-memory-based FPGA architecture with perimeter I/O Blocks (IOBs), a core array of 144 CLBs, and hierarchical interconnect resources including general-purpose grids, direct interconnects, and horizontal longlines. Each CLB contains dual flip-flops, five logic inputs (A–E), programmable clock inversion, and a 32×1 look-up table supporting two 4-variable functions or one 5-variable function.
Configuration is loaded via serial or parallel mode into distributed SRAM cells; on-chip initialization logic enables automatic power-up loading from external PROMs (e.g., XC17XX series). IOBs support registered/direct I/O paths, programmable 3-state control, slew-rate limiting, passive pull-up, and dual-clock-edge programmability per die edge.

Equivalent & Alternatives
The following parts are listed as comparable options for similar FPGA applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XC3042A-100PQ100C | 5 V supply, 100-pin PQFP, 1.5–7 ns logic delay, no Soft Startup or configuration error checking | Requires level-shifting for 3.3 V systems; lacks power-up noise mitigation for dense I/O boards | Select only when legacy 5 V infrastructure mandates compatibility and ground bounce risk is mitigated externally |
| XC3142A-3TQ100C | Same package and pinout; differs in speed grade (–3 vs –4), with higher toggle rate (370 MHz vs 320 MHz) and tighter logic delay (1.55 ns vs 1.7 ns) | Suitable for margin-critical high-speed control loops where sub-0.2 ns path reduction improves timing closure | Prefer when design targets >35 MHz system clock and requires maximum timing headroom without layout change |
Compared with XC3042A-100PQ100C, XC3142-3TQ100C delivers 3.3 V operation, built-in Soft Startup, and configuration integrity checking-reducing external BOM count and improving reliability in new designs. Against XC3142A-3TQ100C, it trades minor speed margin for verified production availability and broader temperature-grade validation.

FAQ
What is the maximum system clock frequency supported by XC3142-3TQ100C?
The XC3142-3TQ100C supports system clock speeds over 85 MHz, with guaranteed flip-flop toggle rates up to 370 MHz. Its 1.55–4.1 ns logic delay range and low-skew clock distribution network enable reliable operation at 85 MHz in typical PCB layouts with controlled impedance routing and proper decoupling.
Does XC3142-3TQ100C support in-system reconfiguration?
Yes, XC3142-3TQ100C supports in-system logic changes via serial or parallel configuration modes. The device can reload its configuration bitstream dynamically without power cycle, enabling field-upgradable functionality and adaptive hardware behavior-provided external PROM or processor interface meets timing requirements for PROGRAM and INIT handshaking.
Is XC3142-3TQ100C pin-compatible with XC3042A devices?
No-XC3142-3TQ100C uses a 3.3 V I/O architecture and TQFP-100 package, while XC3042A uses 5 V operation and PQFP-100. Though both have 100 pins and similar I/O count, voltage mismatch and differing power pin assignments (VCCO/VCCINT vs single VCC) prevent direct pin-to-pin replacement without schematic and layout revision.
What development tools are required to program XC3142-3TQ100C?
XC3142-3TQ100C requires Xilinx Foundation Series or Alliance Series software (v2.x–v3.x), which provides schematic capture, automatic place-and-route, logic/timing simulation, and bitstream generation. Configuration is performed via JTAG boundary-scan or dedicated serial/parallel programming interfaces using XC17XX PROMs or microcontroller-controlled loading.
How does the Soft Startup feature of XC3142-3TQ100C improve system reliability?
The Soft Startup feature in XC3142-3TQ100C automatically limits output slew rate during initial power-up, preventing simultaneous switching noise (SSN) and ground bounce across its 96 I/Os. This eliminates need for external slew-rate resistors or staggered power sequencing, reducing EMI and improving signal integrity in dense PCB environments-especially critical for mixed-signal medical or industrial systems.
