Product details
Overview
XC1704LPC44I from Xilinx is a one-time programmable (OTP) configuration PROM designed to store 4,194,304-bit FPGA bitstreams for Xilinx XC4000XV and XCV series FPGAs in Master Serial mode. It operates at 3.0–3.6 V, supports cascading via CEO/CE daisy-chain, features programmable reset polarity, and delivers 45 ns CLK-to-data delay with 10 mA active supply current.
For engineers reviewing the XC1704LPC44I datasheet, pinout, applications, or equivalent options, key selection criteria include industrial temperature range (–40°C to +85°C), 44-pin PLCC package compatibility, 3.3 V-only operation, cascading support for multi-FPGA systems, and guaranteed 20-year data retention.
Technical Context
The XC1704LPC44I functions as a synchronous serial memory interface: its internal address counter increments on each rising CLK edge when CE and OE are active, outputting configuration data on the DATA pin aligned to CCLK from the master FPGA. The RESET/OE pin-programmable as active-high or active-low-resets the counter and places DATA in high-impedance state.
In cascaded configurations, the CEO output of this device drives the CE input of the next PROM; TCAC max = 45 ns ensures timing compliance with XCV400E/XCV600E FPGAs. Standby mode is entered when CE = High, reducing ICCS to 350 µA with DATA held high-Z regardless of OE state.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory capacity | 4,194,304 bits - stores full configuration bitstream for XCV400E (2.5 Mbit) and XCV600E (3.96 Mbit) FPGAs |
| Supply voltage | 3.0–3.6 V - compatible only with 3.3 V FPGA systems; VPP must be tied to VCC during read operation |
| Operating temperature | –40°C to +85°C - qualified for industrial environments without derating |
| CLK-to-data delay (TCAC) | 45 ns max - enables reliable configuration at up to 14.8 MHz CCLK (67 ns min period) |
| Active supply current | 10 mA max - low power consumption during FPGA configuration burst |
| Standby supply current | 350 µA max - achieved when DATA pin is pulled to VCC or GND |
| Data retention | 20 years - guaranteed non-volatile storage without refresh or backup power |
Pinout & Package
XC1704LPC44I is housed in a 44-pin Plastic Chip Carrier (PLCC) package with 0.050" lead pitch and JEDEC MS-026 compliant footprint. Pin 1 is located at the index corner; pins 11–17, 19–20, 22–23, 25–26, 28–30, 32–33, 35–36, 39, and 42 are no-connects.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 6, 7, 9, 10, 18, 21, 24, 27, 29, 31, 34, 37, 38, 40, 41, 43, 44 | No-connect | Internally unconnected; must remain floating or grounded per PCB layout best practice |
| 3 | RESET/OE | Dual-function pin: programmable as active-High RESET or active-Low OE; drives FPGA INIT for synchronized counter reset |
| 5 | CE | Chip Enable: High disables address counter and forces DATA into high-Z; driven by FPGA DONE or LDC |
| 8 | CEO | Chip Enable Output: goes Low after terminal count to enable next PROM in daisy chain |
| 12 | DATA | Serial data output: connects directly to FPGA DIN; high-Z when CE or OE inactive |
| 13 | CLK | Configuration clock input: driven by FPGA CCLK; rising edge advances address counter |
| 24, 31 | GND | Ground reference: both pins must be connected to system ground plane for noise immunity |
| 37 | VCC | 3.3 V power supply: requires local 0.1 µF ceramic decoupling capacitor |
| 41 | VPP | Programming voltage: tied to VCC during normal operation; floating or incorrect voltage causes undefined behavior |
Key Features

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XC1704LVQ44C | Same 4,194,304-bit capacity and 44-pin footprint, but commercial temperature range (0°C to +70°C) and VQFP package | Suitable for lab-grade or non-industrial deployments; lacks industrial qualification and PLCC mechanical robustness | Select when cost sensitivity outweighs environmental ruggedness and board-level rework tolerance is acceptable |
| XC1702LPC44I | 2,097,152-bit capacity (half size), identical 44-pin PLCC, industrial temp, same 3.3 V supply and AC timing specs | Matches smaller FPGAs like XCV200E (1.3 Mbit); insufficient for XCV400E/XCV600E full configuration | Choose only if target FPGA configuration size ≤ 2 Mbit; verify bitstream fit before design-in |

FAQ
What is the maximum configuration clock frequency supported by XC1704LPC44I?
The XC1704LPC44I supports a minimum clock period (TCYC) of 67 ns, enabling a maximum configuration clock frequency of 14.8 MHz. This is validated for industrial temperature range operation and aligns with the CCLK specifications of XCV400E and XCV600E FPGAs. Timing assumes proper load conditions (50 pF) and valid VIH/VIL levels.
Can XC1704LPC44I be used with 5 V FPGAs?
No, XC1704LPC44I is a 3.3 V-only device (VCC = 3.0–3.6 V) and is not compatible with 5 V FPGA families such as XC4000E or XC5200 series. It is intended exclusively for Xilinx 3.3 V FPGAs including XC4000XV, XCV, and XCV-E families. Using it with 5 V systems risks damage or undefined behavior.
How is the RESET/OE polarity configured for XC1704LPC44I?
The RESET/OE polarity of XC1704LPC44I is programmed during device programming using Xilinx Alliance/Foundation software or third-party programmers supporting XC1700L algorithms. The default is active-High RESET, but active-Low is preferred for direct connection to FPGA INIT. Polarity inversion is performed in the programmer interface-not via external circuitry.
Is VPP required to be externally driven during normal operation of XC1704LPC44I?
No-during normal read operation, VPP must be connected directly to VCC. Leaving VPP floating or applying incorrect voltage causes unpredictable, temperature-dependent operation and may prevent successful configuration. VPP is only used during programming (with +12.5 V) and is not an active signal in system runtime.
Does XC1704LPC44I support daisy-chaining with other PROM families?
XC1704LPC44I supports daisy-chaining only with other XC1700E/EL/L series PROMs (e.g., XC1701L, XC1702L, XC17512L) due to matched CEO timing (TOCK ≤ 30 ns) and compatible CE/CLK/data handshaking. It is not interoperable with XC18V00 or Platform Flash families, which use different control protocols and voltage levels.
