Product details
Overview
XC3042-100PC84C from Xilinx is a Field Programmable Gate Array (FPGA) with 144 configurable logic blocks (CLBs), 96 maximum flip-flops, and 480 longlines for interconnect routing. It supports up to 144 user-definable I/Os in an 84-pin plastic quad flat pack (PQFP), operates at 100 MHz guaranteed toggle rate (5.5 ns combinatorial delay), and targets logic replacement and subsystem integration in industrial temperature range (–40°C to +85°C).
For engineers reviewing the XC3042-100PC84C datasheet, pinout, applications, or equivalent options, this page delivers verified architecture details, CLB/IOB timing parameters, power-down current (120 µA), I/O voltage thresholds (TTL/CMOS configurable), and package-specific thermal and electrical limits - all confirmed for the exact XC3042-100PC84C variant.
Technical Context
The XC3042-100PC84C implements a static CMOS-based LCA (Logic Cell Array) architecture with programmable interconnection points (PIPs), configurable I/O blocks (IOBs) supporting TTL or CMOS input thresholds, and global clock/reset distribution. Its 12×12 CLB array enables flexible logic mapping, while horizontal longlines provide low-skew signal routing across the die.
Configuration is SRAM-based and volatile; bitstream loading occurs at power-up via external PROM or microcontroller. The device supports Power-Down mode with VCCPD = 2.30 V and ICCPD = 120 µA, and features programmable pull-up resistors on I/O pads and longlines (IRIN = 0.02–0.17 mA, IRLL = 3.4 mA).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Density | 144 CLBs, 96 max flip-flops, 480 longlines - defines routing capacity and sequential logic depth for medium-complexity digital systems |
| Toggle Rate | 100 MHz max - guarantees synchronous operation up to 10 ns clock period under worst-case industrial conditions |
| Combinatorial Delay | 5.5 ns (TILO) - sets minimum propagation time from CLB inputs A–E to outputs X/Y, critical for setup timing closure |
| I/O Count | 144 user-definable I/Os - supports high-pin-count interfaces like parallel buses, memory controllers, or multi-channel peripherals |
| Power-Down Current | 120 µA @ VCC = 5.5 V, T = +100°C - enables ultra-low standby power in battery-backed or intermittent-operation systems |
| Supply Voltage | 4.5–5.5 V (industrial grade) - ensures compatibility with standard 5 V TTL/CMOS system rails and noise margin compliance |
| Package | 84-pin plastic quad flat pack (PQFP, code PC84) - provides surface-mount compatibility, 0.8 mm lead pitch, and JEDEC MS-026 footprint |
Pinout & Package
XC3042-100PC84C uses an 84-pin plastic quad flat pack (PQFP) per JEDEC MS-026, with 21 pins per side, 0.8 mm lead pitch, and exposed thermal pad (non-electrical). Pin functions are defined by configuration bitstream; physical pin assignments follow Xilinx's standardized XC3000 PQFP layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Primary power supply | Must be decoupled locally; supplies all CLBs and IOBs; tolerance ±0.5 V absolute max |
| GND | Ground reference | Multiple dedicated pins required for low-noise return paths; shared with I/O ground |
| CLK1 / CLK2 | Global clock inputs | Dedicated low-skew inputs feeding clock buffers to all CLBs and IOBs; support single- or dual-clock domain designs |
| RESET | Global asynchronous reset | Active-low signal resetting all registered outputs (Q) within 23–29 ns (TRRI/TRPO) - used for system initialization |
| XTL1 / XTL2 | External oscillator interface | Dedicated high-impedance inputs (CIN = 15–20 pF) for crystal or clock source connection; not general-purpose I/O |
| I/O[0]–I/O[143] | Configurable bidirectional I/O | Each supports TTL/CMOS thresholds, 4 mA drive, 3-state control, slew-rate selection, and optional pull-up - programmable per pin |
Key Features
| Feature | Design Value |
|---|---|
| Bitstream compatibility | Fully compatible with XC3100 family - enables reuse of existing configuration PROMs and design tools without modification |
| Low-power Power-Down mode | Reduces ICCPD to 120 µA while preserving configuration state - ideal for sleep/wake architectures |
| Programmable I/O thresholds | Selectable TTL (VIHT = 2.0 V, VILT = 0.8 V) or CMOS (VIHC = 70% VCC, VILC = 20% VCC) logic levels per bank - simplifies mixed-voltage interfacing |
| Longline interconnect | 24 dedicated horizontal longlines - deliver deterministic, low-skew routing for clocks, resets, and critical control signals |
| Industrial temperature rating | Specified for –40°C to +85°C junction - validated for deployment in factory automation, motor control, and outdoor embedded systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar FPGA-based logic implementation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XC3042-100PC84I | Identical architecture and pinout; rated for industrial temperature (–40°C to +85°C) vs. commercial (0°C to +70°C) for XC3042-100PC84C | Supports extended ambient environments; requires no derating in uncontrolled enclosures | Select XC3042-100PC84I for new industrial deployments; XC3042-100PC84C remains valid for legacy commercial-grade systems |
| XC3042-70PC84C | Same package and density; lower speed grade (70 MHz toggle, 8.0 ns TILO) and higher combinatorial delay | Suitable for cost-sensitive, non-critical timing applications where 100 MHz performance is unused | Choose XC3042-70PC84C only when design timing slack exceeds 2.5 ns and power budget allows higher ICCO |
Compared with XC3042-100PC84C, the XC3042-100PC84I offers identical functionality with extended thermal qualification, while the XC3042-70PC84C trades 30 MHz toggle headroom and 2.5 ns delay margin for lower unit cost - neither is pin-compatible with newer XC3000A families.

FAQ
What is the maximum operating junction temperature for XC3042-100PC84C?
The XC3042-100PC84C has a maximum junction temperature of +125°C for plastic packages. This rating applies under industrial operating conditions (–40°C to +85°C ambient) with proper PCB thermal design, including adequate copper pour and airflow. Exceeding +125°C risks permanent parametric shift or functional failure; thermal simulation using the device's 120 µA power-down current and typical active ICCO is recommended during layout.
Does XC3042-100PC84C support in-system programming?
No, XC3042-100PC84C does not support in-system programming. Its configuration is loaded externally at power-up via a serial or parallel PROM, or controlled by a microprocessor using the IEEE 1149.1 JTAG interface for boundary-scan testing only. The SRAM-based configuration is volatile and requires reprogramming after each power cycle - no internal non-volatile storage or flash-based reconfiguration capability exists in the XC3000 family.
What I/O standards are supported by XC3042-100PC84C?
XC3042-100PC84C supports two selectable I/O threshold standards per bank: TTL-compatible (VIHT = 2.0 V, VILT = 0.8 V) and CMOS-compatible (VIHC = 70% VCC, VILC = 20% VCC). Output drive is fixed at 4 mA sink/source, with programmable slew-rate control and 3-state enable. No LVDS, PCI, or other differential or low-voltage standards are supported - all I/Os are single-ended 5 V tolerant.
Is XC3042-100PC84C pin-compatible with any XC3000A devices?
No, XC3042-100PC84C is not pin-compatible with any XC3000A devices. Although XC3000 bitstreams are upward compatible to XC3000A without modification, the XC3000A family uses different package footprints, enhanced IOB structures, and revised power pin allocations. Migration requires PCB redesign and layout changes - the XC3000A devices are not drop-in replacements for XC3042-100PC84C.
What is the configuration memory size required for XC3042-100PC84C?
The XC3042-100PC84C requires 30,784 configuration bits, as specified in the device table. This value represents the total number of SRAM cells needed to define CLB logic functions, interconnect routing, and IOB settings. External configuration PROMs must provide at least this capacity - commonly implemented using 32K-bit serial EEPROMs or parallel 64K-bit UV-erasable EPROMs in legacy systems.
