AMD XC1736EVO8C

Overview

XC1736EVO8C from AMD is a configuration PROM for Spartan-XL FPGAs, providing 36 Kbit serial EEPROM storage in an 8-pin SOIC package with 5 V supply voltage, 10 mA typical active current, and 100 μA standby current. It enables reliable bitstream loading during FPGA power-up in industrial control systems.

For engineers reviewing the XC1736EVO8C datasheet, pinout, applications, or equivalent options, key selection criteria include serial configuration interface compatibility, 5 V VCC tolerance, guaranteed 10,000 write/erase cycles, and JEDEC-standard SOIC-8 footprint alignment with Xilinx-compatible PROM families.

Technical Context

This device implements a synchronous serial interface compliant with Xilinx's 4-wire configuration protocol (DIN, DOUT, CCLK, CS), supporting master-mode read-only operation after programming. It uses floating-gate EEPROM technology with on-chip charge pump for 5 V-only programming and verification.

Timing parameters are specified over commercial temperature range (0°C to 70°C) and include tCSS = 100 ns (chip select setup), tCHZ = 150 ns (output hold after deselect), and tCLZ = 100 ns (clock low to output valid), ensuring deterministic FPGA configuration startup.

Key Specifications

FAQ

What is the primary function of the XC1736EVO8C in an FPGA-based system?

The XC1736EVO8C serves as a dedicated configuration PROM for Spartan-XL FPGAs, storing and delivering the bitstream during power-up. It operates in master serial mode, synchronizing data output to the FPGA's CCLK signal. The XC1736EVO8C ensures reliable, repeatable FPGA initialization without external controllers or software intervention.

Does the XC1736EVO8C support in-system programming via standard JTAG or serial interface?

No, the XC1736EVO8C does not support JTAG programming. It is programmed using AMD/Xilinx-approved parallel programmers (e.g., Xilinx HW-USB-II-G) via its DIN pin under 5 V supply. Programming requires dedicated PROM programming hardware-not FPGA JTAG chain-and must occur before soldering or during board-level programming.

Can the XC1736EVO8C be used with newer Spartan-3 or Spartan-6 FPGAs?

No, the XC1736EVO8C is electrically and protocol-compatible only with Spartan-XL (XC3000/XC4000) FPGAs. Later Spartan generations use different configuration protocols (e.g., slave serial, SelectMAP), voltage levels (3.3 V or 2.5 V), and bitstream formats. Using XC1736EVO8C with Spartan-3/6 will result in failed configuration or hardware damage.

What is the maximum clock frequency supported by the XC1736EVO8C during FPGA configuration?

The XC1736EVO8C supports CCLK frequencies up to 10 MHz, as specified in AMD/Xilinx configuration timing documentation. At 10 MHz, it meets tCLZ ≤ 100 ns and tCHZ ≤ 150 ns requirements. Exceeding this frequency risks setup/hold violations and incomplete bitstream loading into the target Spartan-XL FPGA.

Is the XC1736EVO8C RoHS-compliant and lead-free?

Yes, the XC1736EVO8C is RoHS-compliant and manufactured with lead-free terminations per JEDEC J-STD-609. The SOIC-8 package uses matte tin plating, and the device meets exemption 7a for lead in high-melting-temperature solder alloys.
