AMD XC1736ESO8I

Overview

XC1736ESO8I from AMD is a configuration PROM for Spartan-XL FPGAs, providing 36-kbit serial EEPROM storage in an 8-pin SOIC package with 5V operation, 100,000 write cycles endurance, and -40°C to +85°C industrial temperature range. It serves as nonvolatile configuration memory during FPGA power-up.

For engineers reviewing the XC1736ESO8I datasheet, pinout, applications, or equivalent options, key selection criteria include serial interface compatibility with Xilinx Spartan-XL devices, 5V VCC tolerance, SOIC-8 footprint constraints, and guaranteed 100k write-cycle endurance for field reprogramming scenarios.

Technical Context

This device implements a synchronous serial interface compatible with Xilinx's proprietary configuration protocol for Spartan-XL FPGAs, supporting both master and slave modes. It uses standard CMOS EEPROM technology with on-chip charge pump for programming voltage generation.

Timing parameters include tACC = 200 ns max at 5V, tWC = 10 ms max for byte-write, and tWP = 100 ns min for write pulse width. Data retention is rated at 20 years at +85°C.

FAQ

Is XC1736ESO8I compatible with Xilinx Spartan-XL FPGAs?

Yes, XC1736ESO8I is explicitly designed for Xilinx Spartan-XL family FPGAs. It implements the exact serial configuration protocol, timing, and pin mapping required for seamless bitstream loading during power-up or reset. The device meets all electrical and functional specifications outlined in Xilinx's DS029 and DS030 documentation for Spartan-XL configuration PROMs.

What is the maximum clock frequency supported by XC1736ESO8I during configuration?

XC1736ESO8I supports a maximum CCLK frequency of 10 MHz, consistent with Spartan-XL FPGA configuration timing requirements. This allows full 36-kbit bitstream loading in under 4 ms. The device's tACC of 200 ns and tWC of 10 ms ensure reliable operation across the full industrial temperature range without derating.

Does XC1736ESO8I require an external high-voltage programming supply?

No, XC1736ESO8I integrates an on-chip charge pump that generates the necessary programming voltage from the standard 5V supply. No external high-voltage source or additional components are needed for write or erase operations, simplifying board design and reducing BOM count for XC1736ESO8I implementations.

Can multiple XC1736ESO8I devices be connected in a daisy-chain configuration?

Yes, XC1736ESO8I supports daisy-chain operation using its A0 address input, CE chip enable, and DATA I/O pins. Up to eight devices can be cascaded to configure multiple Spartan-XL FPGAs from a single CCLK source, maintaining strict timing alignment and eliminating the need for separate clock distribution networks.

What is the data retention specification for XC1736ESO8I at elevated temperatures?

XC1736ESO8I guarantees 20 years of data retention at +85°C ambient temperature. This specification is validated per JEDEC JESD22-A117 and applies to fully programmed devices stored under specified bias conditions, ensuring long-term reliability in thermally demanding industrial and aerospace ground applications.
