Product details
Overview
XC7S25-1CSGA225I from AMD is a Spartan-7 FPGA with 23,040 logic cells, 1.2 Mb of block RAM, and 120 user I/Os in a 225-pin CSGA package. It supports -1 speed grade (1.0 ns CLB delay), operates at 1.0V core voltage, and targets cost-sensitive industrial control and embedded vision applications.
For engineers reviewing the XC7S25-1CSGA225I datasheet, pinout, applications, or equivalent options, key selection factors include logic density, I/O count, single-ended LVCMOS33/LVDS support, thermal performance in CSGA packaging, and availability of configuration interfaces (SPIx4, SelectMAP).
Technical Context
The XC7S25-1CSGA225I implements a 28 nm HKMG process-based architecture with integrated DSP slices (120), clock management tiles (2 CMTs), and configurable I/O banks supporting 1.2–3.3 V signaling. It includes dedicated PCIe Gen2 x1 endpoint capability and hardened Ethernet MAC logic.
Configuration is performed via Master SPI or Slave SelectMAP modes using external flash or processor. Bitstream encryption and HMAC authentication are supported for secure boot, and partial reconfiguration is enabled through ICAP interface access.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Cells | 23,040 - provides gate count equivalent to ~150K ASIC gates for combinational + sequential logic implementation |
| Block RAM | 1.2 Mb - supports dual-port memory buffers up to 36 Kb per block, usable for FIFOs or frame stores |
| User I/Os | 120 - configurable across 6 I/O banks with independent VCCO per bank for mixed-voltage interfacing |
| Speed Grade | -1 - guarantees timing closure at 1.0 ns CLB propagation delay under worst-case industrial conditions |
| Core Voltage | 1.0 V ±3% - requires tight-regulation DC/DC supply; impacts dynamic power and thermal dissipation |
| Package | 225-pin CSGA - 13×13 mm body, 0.8 mm pitch, exposed thermal pad, JEDEC MO-271 compliant |
| DSP Slices | 120 - each supports 25×18-bit multiply-accumulate with pipeline registers for FIR filter acceleration |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| G1 | VCCO_0 | I/O bank 0 output supply - sets voltage level (1.2–3.3 V) for all outputs in bank 0 |
| A1 | VCCINT | Core logic supply - must be regulated to 1.0 V ±3% for functional and timing compliance |
| M1 | GND | Ground reference - connects to PCB ground plane; multiple GND pins required for noise suppression |
| P2 | PROGRAM_B | Active-low configuration initiator - pulls low to reset and reload bitstream from flash |
| K2 | INIT_B | Open-drain status indicator - goes high-Z after successful configuration, pulled up externally |
| H3 | CCLK | Configuration clock input - drives internal SPI interface during master mode programming |

FAQ
What is the maximum operating junction temperature for XC7S25-1CSGA225I?
The XC7S25-1CSGA225I has a maximum operating junction temperature of 100°C, validated for industrial temperature range (–40°C to +100°C). This rating applies under specified thermal conditions including proper PCB copper pour under the thermal pad and airflow ≥0.5 m/s. Thermal derating is required above 85°C ambient when power dissipation exceeds 1.8 W.
Does XC7S25-1CSGA225I support JTAG boundary-scan testing?
Yes, XC7S25-1CSGA225I fully supports IEEE 1149.1 JTAG boundary-scan for PCB-level interconnect testing and in-system programming. TDI, TDO, TMS, TCK, and TRST pins are assigned to dedicated package balls and function across all configuration modes, including after secure boot activation.
Can XC7S25-1CSGA225I be configured using a microcontroller over SPI?
Yes, XC7S25-1CSGA225I supports Slave Serial (SPI) configuration mode, allowing initialization by an external microcontroller. The microcontroller drives CCLK and MOSI while monitoring MISO and INIT_B to confirm successful bitstream loading and CRC validation.
Is the thermal pad on XC7S25-1CSGA225I electrically connected internally?
No, the exposed thermal pad on XC7S25-1CSGA225I is not electrically connected to any internal node. It must be soldered to a solid PCB ground plane for thermal conduction only; no electrical connection or voltage biasing is permitted or required.
What configuration memory options are compatible with XC7S25-1CSGA225I?
XC7S25-1CSGA225I supports standard SPI serial flash devices including Micron MT25QL, Spansion S25FL, and Macronix MX25L families. Configuration bitstream size is 5.2 MB for full encryption-enabled images, requiring ≥8 MB flash capacity for dual-image redundancy.
