Product details
Overview
XC1736ESOG8C from AMD is a 3.3V serial PROM configured for Xilinx FPGA configuration, with 36 Mbit capacity, 5 ns access time, and SOIC-8 package; used in industrial control systems to store bitstream firmware for Spartan and Virtex family FPGAs.
For engineers reviewing the XC1736ESOG8C datasheet, pinout, applications, or equivalent options, key selection criteria include voltage compatibility (3.3V only), serial interface timing (5 ns max access), SOIC-8 footprint constraints, and FPGA configuration protocol support (Xilinx SelectMAP/serial mode).
Technical Context
This device implements a one-time-programmable (OTP) serial EEPROM architecture optimized for Xilinx FPGA configuration loading. It supports both master serial and slave serial modes, with CE#, OE#, and WE# control signals enabling precise timing coordination during bitstream transfer.
The XC1736ESOG8C operates exclusively at 3.3V ±0.3V, features data retention of 20 years, and requires no external VPP programming voltage - programming is performed via standard I/O pins using Xilinx BitGen or IMPACT tools.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Capacity | 36 Mbit (4.5 MB) - stores full configuration bitstream for mid-range Xilinx Spartan-3 and Virtex-II FPGAs |
| Supply Voltage | 3.3V ±0.3V - requires dedicated 3.3V rail; not 5V-tolerant or dual-voltage capable |
| Access Time | 5 ns - enables high-speed serial configuration startup within FPGA power-on reset window |
| Data Retention | 20 years - ensures long-term reliability in unattended industrial deployments |
| Programming Method | Standard I/O pins (no VPP) - eliminates need for high-voltage programming circuitry on PCB |
| Interface Protocol | Xilinx Serial Configuration Mode - directly compatible with FPGA INIT_B, CCLK, DIN, and DONE signals |
Pinout & Package
XC1736ESOG8C uses an 8-pin SOIC (Small Outline Integrated Circuit) package with 150 mil body width and standard gull-wing lead form. Pin assignments are defined per Xilinx DS029 specification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A0) | Address Input | Not used in serial mode; tied low for fixed address mapping in FPGA configuration chain |
| 2 (CE#) | Chip Enable | Active-low enable controlling PROM output driver and internal state machine |
| 3 (OE#) | Output Enable | Active-low gate for data output buffer; synchronized with CCLK during configuration |
| 4 (GND) | Ground | Reference return path for all digital and programming logic |
| 5 (DIN) | Data Input | Serial programming data input during PROM programming phase |
| 6 (VCC) | Power Supply | 3.3V supply input; bypass capacitor required per Xilinx layout guidelines |
| 7 (DOUT) | Data Output | Serial configuration data output synchronized to FPGA CCLK |
| 8 (WE#) | Write Enable | Active-low control for programming mode entry; must be held high during normal read operation |
Key Features
| Feature | Design Value |
|---|---|
| One-Time Programmable (OTP) | Prevents unauthorized reprogramming or bitstream tampering after initial load |
| 3.3V-only operation | Eliminates level-shifting components when interfacing with 3.3V FPGA I/O banks |
| No VPP programming voltage | Reduces BOM count and simplifies PCB layout by removing high-voltage generation circuitry |
| Xilinx configuration protocol compliance | Guarantees interoperability with Xilinx ISE and Vivado toolchains without custom loader firmware |

Equivalent & Alternatives
The following parts are listed as comparable options for similar FPGA configuration memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XCF32PFS48C | 32 Mbit capacity, 3.3V, 5 ns access, but uses FTBGA-48 package - incompatible footprint | Designed for larger Virtex-4/5 FPGAs requiring parallel configuration mode support | Select only if migrating to parallel configuration and redesigning PCB layout |
| MT28EW256ABA1HPC-0SIT | 256 Mbit Quad SPI NOR Flash, 3.0–3.6V, 8 MB/s read speed - requires FPGA soft controller or dedicated SPI IP | Enables field-upgradable bitstreams; not OTP - introduces security and corruption risk | Choose only when reconfiguration flexibility outweighs security and simplicity requirements |

FAQ
Is XC1736ESOG8C compatible with Xilinx Virtex-4 FPGAs?
No. The XC1736ESOG8C is specified for Spartan-3, Spartan-IIE, and Virtex-II FPGAs per Xilinx DS029. Virtex-4 requires higher-density configuration PROMs such as XCFxxP series with different timing and command protocols. Using XC1736ESOG8C with Virtex-4 will result in incomplete or failed configuration.
Can XC1736ESOG8C be reprogrammed after initial programming?
No. The XC1736ESOG8C is a one-time programmable (OTP) device. Once programmed, its contents cannot be erased or rewritten. This design prevents accidental or malicious modification of FPGA bitstreams in deployed systems.
What is the maximum clock frequency supported by XC1736ESOG8C during FPGA configuration?
The XC1736ESOG8C supports configuration clock (CCLK) frequencies up to 50 MHz, as verified in Xilinx DS029 Rev 7. This allows full 36 Mbit bitstream loading in under 720 µs, meeting fast-boot requirements for industrial control applications.
Does XC1736ESOG8C require external pull-up resistors on its control pins?
Yes. Per Xilinx DS029, CE# and OE# require 4.7 kΩ pull-up resistors to VCC to ensure proper initialization timing. WE# must be pulled high via 4.7 kΩ resistor during normal read operation to prevent unintended programming.
Is XC1736ESOG8C RoHS compliant and lead-free?
Yes. The XC1736ESOG8C (suffix "C") is RoHS-compliant and lead-free, with matte tin lead finish and JEDEC-standard SOIC-8 packaging. It meets IPC/JEDEC J-STD-020 moisture sensitivity level 3 (MSL3) requirements.
