XCF32PVOG48C - 32Mb FPGA Config PROM 1.8V 48-TSOP | AMD
MPN： XCF32PVOG48C ⚠ 最後購買機會XCF32PVOG48C 概覽
A Platform Flash configuration PROM is a non-volatile NOR Flash memory device whose primary role is to hold the FPGA bitstream and present it to the target FPGA over a serial or parallel configuration interface. In the broader memory hierarchy it sits under EEPROM and Flash PROM, and above raw NOR Flash, providing a pre-validated, FPGA-aware configuration storage medium. It relieves the system designer of placing a separate boot Flash on the board and is typically the first device in the FPGA configuration chain.
Key electrical features include a 32 Mbit (4 Mbyte) organized as 1-bit-wide serial/parallel PROM, a 1.65 V to 2.0 V operating voltage range with 3.3 V tolerant I/O pins, low-power advanced CMOS Flash technology, an in-system programmable JTAG/IEEE 1149.1 interface, and cascade support for storing larger bitstreams. The 48-pin TSOP provides a compact, surface-mount footprint compatible with standard PCB assembly lines.
Architecturally, the device uses a NOR Flash core tied to a serial/parallel configuration controller, with dedicated CCLK, DIN/DOUT, and CF pins mapping directly to the FPGA configuration port. The 1.8 V internal core reduces power consumption versus 3.3 V PROMs, which is meaningful when the PROM is continuously powered alongside the FPGA.
Typical applications include Xilinx Virtex and Spartan FPGA configuration boot storage, industrial control boards, communications infrastructure, and test/measurement platforms that require reliable field-upgradable bitstream storage. For military and aerospace designs, AMD also offers the XQF32PVOG48M variant in the same family. When designing with this part, ensure that the FPGA configuration mode (serial vs. parallel) and density match the bitstream size, and verify that the JTAG chain supports ISP programming of the PROM.

典型應用
XCF32PVOG48C 適用於 6 應用s: Xilinx Spartan-3 / Spartan-6 FPGA Boot Storage, Industrial Control Board Configuration Memory, Communication Infrastructure (Switch / Router Backplane), Test & Measurement Equipment Firmware Storage, Aerospace / Mil-Quad Form Factor Boards, Legacy Virtex-4 / Virtex-5 FPGA Boot Retrofits.
Xilinx Spartan-3 / Spartan-6 FPGA Boot Storage
The XCF32PVOG48C operates from a 1.65 V to 2.0 V VCC rail that aligns directly with Spartan-3/3E/6 FPGA VCCO supplies, eliminating a level shifter on the configuration bus. Its 32 Mbit capacity comfortably stores the configuration bitstream for any Spartan-3 device variant (XCS400 to XC3S5000 series), and the JTAG-based in-system programming lets the firmware team update PROM contents through the same chain as the FPGA. Cascade support allows two devices to be chained for Spartan-6 LX150/LX45 bitstreams exceeding 32 Mbit.
推薦
Industrial Control Board Configuration Memory
Industrial PLCs and motor-drive controllers use the XCF32PVOG48C to store the FPGA bitstream governing their DSP control loops, with the 1.8 V Platform Flash family offering lower standby current than 3.3 V PROMs for always-on field deployments. The 48-TSOP surface-mount package withstands standard reflow profiles, and the -40 C to +85 C commercial temperature grade covers typical industrial cabinet ambient. The 32 Mbit capacity leaves headroom for future bitstream revisions without redesigning the PCB footprint.
推薦
Communication Infrastructure (Switch / Router Backplane)
Routers and switches use the XCF32PVOG48C as the boot PROM for the line-card supervisor FPGAs handling packet processing and SERDES control. The 1.8 V VCCINT minimizes the always-on power budget on a dense backplane, while 3.3 V-tolerant I/O ports interface directly with multi-voltage FPGA configuration buses without extra components. JTAG ISP programming lets NCM teams service bitstream bugs across a deployed fleet without swapping hardware.
推薦
Test & Measurement Equipment Firmware Storage
Test instruments use the XCF32PVOG48C to store the FPGA bitstream responsible for stimulus generation, DSP capture, and protocol decoding. The 32 Mbit capacity is sufficient for large Virtex-4 LX25/LX40 image-generation bitstreams, and the JTAG re-programmability lets designers ship calibration updates to deployed instruments. Low power consumption keeps thermal budget predictable in sealed industrial chassis.
推薦
Aerospace / Mil-Quad Form Factor Boards
For boards that must double as industrial and MIL-grade builds, the XCF32PVOG48C is the preferred commercial part and the XQF32PVOG48M is the verified military-grade drop-in alternative sharing the identical 48-TSOP footprint. Designs that started with XCF32PVOG48C can be re-certified for harsh environments simply by substituting the XQF variant during line-build, without any PCB rework.
推薦
Legacy Virtex-4 / Virtex-5 FPGA Boot Retrofits
Designers maintaining deployed Virtex-4 LX/LXT and Virtex-5 LX/SXT boards use the XCF32PVOG48C as a 1.8 V low-power replacement for legacy 3.3V Platform Flash PROMs, because both Virtex-4 and the 1.8 V PROM share the same 1.5 V to 3.3 V tolerant configuration interface. This avoids redesigning the configuration pin mapping and reduces standby current on the backplane by ~40 percent.

主要差異化特點
- Exact 32 Mbit density for full Spartan-6 LX16 bitstream storage (對比XCF16PVOG48C)
- Commercial-grade 1.8 V Platform Flash XL with verified drop-in upgrades (對比XQF32PVOG48M)
- Standard 1.65 to 2.0 V VCCINT range matches all Spartan-3/6 VCC rails (對比XCF32PFS48C (LQFP package variant))
設計說明
Estimated: at FPGA configuration when VCC is 1.8 V and the PROM is actively driving CCLK/DOUT at full speed, standby current remains below 25 mA per the AMD Platform Flash datasheet, but it is recommended to power the XCF32PVOG48C from a regulated LDO rail sharing the FPGA VCCO_0 supply. Avoid sourcing its VCCINT directly from a noisy switching converter without a 10 uF ceramic + 0.1 uF decoupling network placed within 5 mm of the pin.
Route the JTAG chain (TDI/TDO/TMS/TCK) as a daisy chain from the FPGA to the XCF32PVOG48C with stub lengths under 30 mm. Place the TSOP on the same board side as the FPGA JTAG header so taps are not interrupted by connectors. Keep CCLK trace matched to 50 ohm impedance when using parallel mode; for serial mode match the impedance but accept a slightly relaxed 65 ohm spec.
Do not confuse the 1.8 V Platform Flash XCF32P family with the 3.3 V Platform Flash XCF32S family - they share the 48-TSOP footprint but are not pin-compatible at the VCC rail and may permanently damage the 1.8 V part. Always verify the 'V' versus 'S' family code in the part number (XCF32PVOG48C versus XCF32PSOG48C) and confirm VCCINTRail before PCB layout checkout.
合規資訊
Lead-free / RoHS-compliant per AMD product page (VOG48C suffix indicates lead-free); AEC-Q100 not applicable because PROM is not an automotive-grade device; choose XQF32PVOG48M for MIL-grade / aerospace qualification.
