Product details
Overview
XC1736EPC20C from AMD is a 36-kbit serial PROM configured as 4,096 × 8, operating at 5 V with access time of 20 ns, used for FPGA configuration storage in Xilinx Spartan and Virtex families.
For engineers reviewing the XC1736EPC20C datasheet, pinout, applications, or equivalent options, key selection criteria include 5 V supply compatibility, 20 ns read access timing, serial (SPI-like) interface architecture, and industrial temperature range support.
Technical Context
This device implements a CMOS-based serial configuration memory with single 5 V supply operation and TTL-compatible I/O. It uses a 3-wire interface (CLK, DATA, CE) and supports sequential read mode for fast bitstream loading.
The XC1736EPC20C features built-in power-on reset circuitry and data retention exceeding 20 years. Its internal address counter enables automatic incrementing during read cycles without external address management.

FAQ
What is the primary function of the XC1736EPC20C in FPGA-based systems?
The XC1736EPC20C serves as a non-volatile serial PROM storing FPGA configuration bitstreams. During power-up, it delivers the stored bitstream to the target FPGA via a 3-wire interface. The XC1736EPC20C ensures repeatable, deterministic initialization without requiring external programming hardware each time.
Does the XC1736EPC20C support 3.3 V operation?
No, the XC1736EPC20C is specified exclusively for 5.0 V ±10% operation. It is not rated for 3.3 V supply and may fail to initialize or exhibit data corruption if operated outside its 4.5–5.5 V range. Systems migrating to lower voltages require alternatives such as the XCF04SVO20C or AT25DF041A-SH-B.
Can the XC1736EPC20C be used with modern Xilinx FPGA families?
The XC1736EPC20C was designed for Xilinx Spartan and Virtex families introduced before 2003. Its 36 kbit capacity is insufficient for Spartan-3 and later devices. While electrically compatible in legacy sockets, the XC1736EPC20C cannot hold modern bitstreams - newer FPGAs require at least 1 Mbit of configuration memory.
What is the pin compatibility status between XC1736EPC20C and XC1764EPC20C?
The XC1736EPC20C and XC1764EPC20C share identical 20-pin DIP packaging and pinout, including CE, CLK, Q0–Q7, A0–A7, VCC, and VSS. However, XC1764EPC20C contains 64 kbit (8,192 × 8) memory and requires different address decoding for full capacity utilization.
How does the XC1736EPC20C handle power-on initialization?
The XC1736EPC20C integrates internal power-on reset circuitry that holds outputs in high-impedance state until VCC stabilizes above 4.5 V. This prevents spurious data output during power ramp-up. Once stable, the device remains ready for read commands without external reset sequencing - a key feature of the XC1736EPC20C.
