Product details
Overview
XC2S15-5TQG144C 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 XC2S15-5TQG144C datasheet, pinout, applications, or equivalent options, key selection criteria include I/O voltage compatibility, logic cell count, timing grade (-5), and TQFP-144 mechanical fit in space-constrained industrial PCBs.
Technical Context
The XC2S15-5TQG144C 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 dividers.
Configuration is performed via serial mode using an external PROM or parallel slave mode with microprocessor interface. It includes IEEE 1149.1 JTAG boundary-scan support for testing and in-system programming.

FAQ
What is the core supply voltage requirement for XC2S15-5TQG144C?
The XC2S15-5TQG144C requires a 2.5 V ± 5 % core supply (VCCINT). This voltage powers internal logic and CLBs. Stable regulation and local decoupling capacitors near VCCINT pins are mandatory to meet timing and reliability specifications. The XC2S15-5TQG144C does not support 3.3 V core operation.
Does XC2S15-5TQG144C support JTAG programming?
Yes, the XC2S15-5TQG144C includes full IEEE 1149.1 JTAG boundary-scan support for in-circuit testing and configuration. It uses TDI, TDO, TMS, TCK, and TRTST pins for JTAG access. The XC2S15-5TQG144C can be programmed via JTAG in both configuration and debug modes using standard Xilinx tools.
What configuration methods are supported by XC2S15-5TQG144C?
The XC2S15-5TQG144C supports master serial, slave serial, and slave parallel configuration modes. External PROMs (e.g., XCF02S) are commonly used for master serial boot. In slave parallel mode, a microcontroller writes the bitstream directly to the XC2S15-5TQG144C's data bus. Configuration occurs on power-up or after PROGRAM_B assertion.
Is XC2S15-5TQG144C RoHS compliant?
Yes, the XC2S15-5TQG144C is RoHS compliant and lead-free. The "G" in the part number denotes green (halogen-free) packaging. It meets EU Directive 2011/65/EU requirements and is suitable for environmentally regulated industrial and commercial applications.
Can XC2S15-5TQG144C operate with mixed I/O voltages?
Yes, the XC2S15-5TQG144C supports mixed I/O voltages through its 16 independent I/O banks. Each bank can be set to 3.3 V or 2.5 V independently via VCCO pins. This allows interfacing with multiple voltage domains-for example, 3.3 V sensors and 2.5 V FPGAs-without external level shifters.
