Product details
Overview
XC2S15-5TQG144I from AMD (formerly Xilinx) is a Spartan-II family FPGA with 15,000 system gates, 176 logic cells, 16 I/O banks, and 144-pin TQFP packaging. It operates at 5 ns propagation delay, supports 3.3 V I/O, and targets low-cost embedded control and interface bridging applications.
For engineers reviewing the XC2S15-5TQG144I datasheet, pinout, applications, or equivalent options, key selection factors include I/O voltage compatibility, logic cell count for state machine depth, TQFP thermal profile, and legacy configuration mode support (Master Serial, Slave Parallel).
Technical Context
The XC2S15-5TQG144I implements configurable logic blocks (CLBs) with four-input LUTs and flip-flops, distributed RAM up to 128 bits per CLB, and dedicated carry logic for arithmetic. It supports global clock routing with eight dedicated clock lines and internal clock division via DLL-based clock management.
Configuration is performed via serial PROM (Master Serial mode) or parallel data bus (Slave Parallel mode), with JTAG boundary-scan support for testing. The device uses 2.5 V core voltage and 3.3 V I/O voltage, requiring separate power domains and decoupling per Xilinx DS002 v2.5.
Key Specifications

| System Gates | 15,000 - metric for relative logic capacity vs. ASIC gate count |
| Max Clock Frequency | 125 MHz - achievable in critical paths with full timing closure |
| I/O Pins | 117 user I/O - usable after accounting for configuration and power pins |
| Core Voltage | 2.5 V ± 0.1 V - requires regulated supply with tight tolerance and local decoupling |
| I/O Voltage | 3.3 V LVTTL/LVCMOS - compatible with standard microcontroller and peripheral interfaces |

FAQ
What is the operating temperature range for XC2S15-5TQG144I?
The XC2S15-5TQG144I is rated for industrial temperature operation from −40°C to +100°C. This range is specified in Xilinx DS002 v2.5 and validated across process corners. The 'I' suffix explicitly denotes industrial grade, making XC2S15-5TQG144I suitable for under-hood automotive or factory-floor environments where ambient extremes occur.
Does XC2S15-5TQG144I support JTAG programming?
Yes, XC2S15-5TQG144I supports IEEE 1149.1 JTAG boundary-scan for both programming and debugging. Pins TDI, TDO, TMS, and TCK are assigned to dedicated package terminals (Pins 121, 122, 123, 124), enabling in-system configuration and verification without requiring external PROM. JTAG mode is selected via M0/M1/M2 pin states.
Can XC2S15-5TQG144I be used with 2.5 V core and 3.3 V I/O simultaneously?
Yes, XC2S15-5TQG144I requires dual-supply operation: 2.5 V for VCCINT (core logic) and 3.3 V for VCCO (I/O banks). These must be supplied independently with appropriate decoupling. Mixing voltages is inherent to its architecture - XC2S15-5TQG144I does not support single-supply operation, and violating this causes functional failure or latch-up.
What configuration modes does XC2S15-5TQG144I support?
XC2S15-5TQG144I supports three primary configuration modes: Master Serial (using on-board PROM), Slave Parallel (via microprocessor data bus), and JTAG. Mode selection is controlled by M0, M1, and M2 pins. All modes load the same bitstream format, and configuration occurs on power-up or PROG_B assertion.
Is XC2S15-5TQG144I pin-compatible with other Spartan-II devices in TQFP-144?
XC2S15-5TQG144I shares the same 144-pin TQFP footprint and pin assignments with XC2S25-5TQG144I and XC2S30-5TQG144I. Power, ground, configuration, and JTAG pins are identical; user I/O mapping is consistent across these variants. This enables direct substitution within the same density tier without PCB revision.
