Product details
Overview
XC3042-125PQ100C from Xilinx is a 12×12 configurable logic block (CLB) Field Programmable Gate Array with 144 user I/Os, 96 flip-flops, and guaranteed 125 MHz maximum toggle rate. It implements combinational and sequential logic using static CMOS memory cells, supports TTL/CMOS input thresholds, and operates at 4.75–5.25 V in commercial temperature range (0°C to +70°C) for embedded control and digital subsystem integration.
For engineers reviewing the XC3042-125PQ100C datasheet, pinout, applications, or equivalent options, key selection criteria include CLB count (144), I/O count (144), -125 speed grade timing (TCKO = 4.5 ns, TPID = 7.0 ns), power-down current (120 µA), and PQ100 package compatibility with standard PCB layout practices.
Technical Context
The XC3042-125PQ100C implements a fine-grained, SRAM-based FPGA architecture with dedicated global clock and reset distribution networks. Its CLBs contain dual function generators (F/G), flip-flops with synchronous reset, and programmable interconnect points (PIPs) enabling flexible routing of signals across horizontal longlines and local interconnects.
Configuration is performed via serial bitstream loading through dedicated configuration pins (e.g., DIN, CCLK, PROG). The device supports both registered and direct I/O paths, slew-rate controlled outputs, and programmable input thresholds (TTL or CMOS), with timing validated per MIL-M-38510/605 test methodology under worst-case operating conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

FAQ
What is the maximum guaranteed toggle frequency of the XC3042-125PQ100C?
The XC3042-125PQ100C has a maximum guaranteed toggle frequency of 125 MHz, corresponding to its -125 speed grade designation. This value is validated under worst-case commercial operating conditions (VCC = 4.75 V, TJ = +85°C) and reflects the highest clock rate at which all CLB flip-flops can reliably toggle. The XC3042-125PQ100C achieves this performance with a CLB K-to-Q delay (TCKO) of 4.5 ns and input setup time (TDICK) of 3.0 ns.
Does the XC3042-125PQ100C support in-system reconfiguration?
Yes, the XC3042-125PQ100C supports in-system reconfiguration via its serial configuration interface using DIN, CCLK, and PROG pins. Configuration bitstream loading occurs synchronously to CCLK, allowing dynamic logic updates without power cycling. The XC3042-125PQ100C retains full SRAM-based configuration memory, enabling fast reprogramming in under 100 ms depending on bitstream size and clock frequency.
What are the I/O voltage threshold options supported by the XC3042-125PQ100C?
The XC3042-125PQ100C supports programmable input thresholds: TTL-compatible (VIHT = 2.0 V min, VILT = 0.8 V max) and CMOS-compatible (VIHC = 70% VCC min, VILC = 20% VCC max). These thresholds are configured per I/O bank during bitstream generation and allow direct interfacing with 5 V TTL, LVTTL, and CMOS logic families without external level shifters - critical for mixed-signal system integration.
Is the XC3042-125PQ100C pin-compatible with other XC3042 speed grades?
Yes, the XC3042-125PQ100C is fully pin-compatible with all other XC3042 variants in the PQ100 package, including XC3042-100PQ100C and XC3042-70PQ100C. All share identical pin assignments, power/ground distribution, configuration interface signals (DIN, CCLK, PROG), and I/O pad layout - enabling drop-in replacement for timing validation or cost optimization without PCB revision.
What is the power-down supply current (ICCPD) specification for the XC3042-125PQ100C?
The XC3042-125PQ100C has a specified power-down supply current (ICCPD) of 120 µA at VCC = 5.25 V and TJ = +85°C, measured with PWRDWN asserted low and no active loads. This ultra-low ICCPD enables extended standby operation in power-sensitive applications. Special product codes (e.g., SPC0107) can further reduce ICCPD to 3 µA at 3.2 V and 25°C for ultra-low-power variants.
