AMD XC7A15T-2CPG236I

Overview

XC7A15T-2CPG236I from AMD (formerly Xilinx) is a Spartan-7 FPGA featuring 15,840 logic cells, 1.2 Mb of block RAM, and 120 DSP slices, packaged in a 236-pin CP (Chip Scale Package) with 0.5 mm pitch. It supports I/O standards up to 1.8 V, operates at -40°C to +100°C industrial temperature range, and targets cost-sensitive embedded control and interface bridging applications.

For engineers reviewing the XC7A15T-2CPG236I datasheet, pinout, applications, or equivalent options, key selection criteria include logic density, I/O voltage flexibility, thermal performance in compact PCB layouts, and availability of hardened PCIe Gen2 endpoints in compatible Spartan-7 variants.

Technical Context

The XC7A15T-2CPG236I implements a 28 nm HKMG process-based architecture with configurable logic blocks (CLBs), distributed RAM, shift registers, and dedicated carry chains. It integrates dual 32-bit AXI4-Lite interfaces for configuration and debug, and supports SelectIO™ technology with programmable slew rate and drive strength per bank.

This device lacks integrated transceivers or PCIe hard IP - those features are present only in higher-density Spartan-7 parts (e.g., XC7S25 and above). Its configuration is performed via Master SPI or JTAG, with bitstream encryption supported through AES-256 key storage in eFUSE.

FAQ

Does XC7A15T-2CPG236I support PCIe Gen2 endpoints?

No. The XC7A15T-2CPG236I does not include hardened PCIe Gen2 endpoints. That capability is reserved for larger Spartan-7 devices such as XC7S25 and above. Designers requiring PCIe must select a higher-density variant or implement soft-core solutions, which consume significant logic resources in XC7A15T-2CPG236I.

What configuration modes are supported by XC7A15T-2CPG236I?

The XC7A15T-2CPG236I supports Master SPI, Slave Serial, JTAG, and Boundary Scan configuration modes. Mode selection is controlled by external pull-up/pull-down resistors on M0–M2 pins at power-up. Bitstream loading occurs automatically after reset, with optional AES-256 decryption enabled via eFUSE programming.

Is XC7A15T-2CPG236I pin-compatible with other Spartan-7 devices in the CP236 package?

XC7A15T-2CPG236I shares the same 236-ball CP package footprint with XC7A35T-2CPG236I and XC7A50T-2CPG236I, but pin functions differ across densities due to varying I/O bank allocations and internal routing. Direct replacement requires verification of I/O assignment compatibility and may necessitate PCB layout changes.

Can XC7A15T-2CPG236I operate at 1.2 V I/O voltage?

Yes. XC7A15T-2CPG236I supports 1.2 V I/O operation in banks configured for LVCMOS12 or SSTL12 standards. Each I/O bank has independent VCCO supply, allowing mixed-voltage operation across banks - for example, one bank at 1.2 V for memory interface and another at 1.8 V for microcontroller communication.

What is the maximum operating frequency of the internal clock management tile (CMT) in XC7A15T-2CPG236I?

The XC7A15T-2CPG236I contains a single MMCM (Mixed-Mode Clock Manager) with input frequency range of 10–800 MHz and output range of 6.25–800 MHz. At speed grade -2, the MMCM achieves setup/hold timing closure up to 450 MHz for internally generated clocks driving synchronous logic paths.
