Product details
Overview
AT17LV002-10TQU from Microchip Technology (formerly Atmel) is a 2-Mbit FPGA configuration EEPROM designed to store and serially load bitstream data into SRAM-based FPGAs in Master Serial mode. It supports 3.3V and 5.0V operation, features programmable reset polarity, cascading via CEO output, and operates across -40°C to +85°C. Used in industrial FPGA-based control systems requiring reliable, nonvolatile configuration storage.
For engineers reviewing the AT17LV002-10TQU datasheet, AT17LV002-10TQU pinout, AT17LV002-10TQU application, or AT17LV002-10TQU equivalent, key selection criteria include its 2-Mbit density, 44-lead TQFP package, cascading capability, dual-voltage support, and compatibility with Xilinx, Altera, and Atmel FPGA families.
Technical Context
The AT17LV002-10TQU implements a serial EEPROM architecture optimized for FPGA configuration loading, using a synchronous serial interface driven by the FPGA's CCLK signal. Its internal address counter advances on CLK edges, and DATA output is tri-stated during reset or CE high, enabling clean daisy-chain operation.
It supports In-System Programming (ISP) via 2-wire serial bus when SER_EN is low, and includes write protection via WP1 and RESET/OE polarity programming. The CEO output enables automatic handoff to the next device in a cascaded chain, critical for multi-FPGA or high-density configuration systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 2,097,152 × 1-bit (2 Mbit), sufficient to configure mid-range Xilinx Spartan or Altera Cyclone FPGAs. |
| Supply Voltage | 3.0 V to 5.5 V - supports both 3.3V and 5.0V system rails without level-shifting. |
| Operating Temperature | -40°C to +85°C - qualified for industrial environments with no derating required. |
| Max Clock Frequency | 10 MHz at 3.3V / 15 MHz at 5.0V - matches typical FPGA CCLK timing budgets for fast configuration. |
| Write Endurance | 100,000 cycles - enables field reprogramming of FPGA configurations during development and maintenance. |
| Data Retention | 90 years at 85°C - ensures long-term reliability in unattended embedded deployments. |
| Standby Current | 350 µA at 3.3V - minimizes power draw when CE is high and FPGA is idle. |
Pinout & Package
AT17LV002-10TQU is housed in a 44-lead Thin Quad Flat Package (TQFP), 10.0 mm × 10.0 mm × 1.0 mm body, 0.80 mm lead pitch, RoHS-compliant (Sn finish). Pinout conforms to Figure 1-1 (44-lead TQFP) in Atmel-2321J datasheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| DATA | Three-state bidirectional data I/O | Open-collector output during FPGA configuration; used for serial data transfer and ISP programming. |
| CLK | Input clock | Synchronized to FPGA CCLK; increments internal address counter and controls bit timing. |
| RESET/OE | Programmable active-low reset / output enable | Resets address counter and tri-states DATA; polarity configurable during programming. |
| CE | Chip Enable (active low) | Enables read operation and output driver; high state forces low-power standby mode. |
| CEO | Chip Enable Output (active low) | Signals end-of-data to next cascaded AT17LV device; essential for multi-device chains. |
| READY | Open-collector reset status indicator | Drives low during power-on reset; released when internal initialization completes (requires 4.7kΩ pull-up). |
| SER_EN | Serial Enable input | High = normal FPGA configuration mode; low = enables 2-wire ISP programming. |
| VCC / GND | Power supply pins | Supports 3.3V or 5.0V operation; requires 0.2 µF decoupling capacitor per VCC–GND pair. |
Key Features
| Feature | Design Value |
|---|---|
| In-System Programmability (ISP) | Enables field updates via 2-wire serial bus without removing the device, reducing service downtime. |
| Cascadable CEO output | Allows seamless daisy-chaining of multiple AT17LV devices to support larger FPGA configurations or multi-FPGA boards. |
| Programmable reset polarity | Permits matching FPGA reset logic (active-high or active-low) without external inverters or board redesign. |
| Dual-voltage compatibility | Eliminates need for voltage translators in mixed 3.3V/5.0V systems, simplifying power domain interfacing. |
| Write protection (WP1) | Hardware-enforced block-level protection prevents accidental overwrite of critical configuration sectors during ISP. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar FPGA configuration memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Xilinx XC18V02 | 2-Mbit density, 3.3V-only supply, 8-pin SOIC or PLCC packaging; lacks CEO cascade output and ISP capability. | Designed exclusively for Xilinx FPGAs; not compatible with Altera or Atmel FPGA families. | Select when using only Xilinx devices and board space constraints favor smaller packages. |
| Microchip (Atmel) AT17LV002-10JU | Same 2-Mbit density and functionality, but in 20-lead PLCC package; identical electrical specs and timing. | Preferred for through-hole prototyping or legacy PLCC-based designs; no CEO pin remapping required. | Choose for manual assembly, test fixtures, or backward compatibility with existing PLCC footprints. |
Compared with XC18V02 and AT17LV002-10JU, the AT17LV002-10TQU offers superior flexibility via its 44-lead TQFP footprint (enabling higher I/O routing density), built-in CEO cascade support, and full 3.3V/5.0V dual-rail operation - making it optimal for new industrial and telecom designs requiring scalability and interoperability.

FAQ
What is the memory organization of the AT17LV002-10TQU?
The AT17LV002-10TQU contains 2,097,152 bits organized as 2,097,152 × 1-bit. It does not support byte-wide access; data is read serially, one bit per CLK edge, aligned to FPGA configuration protocol requirements. This structure optimizes silicon area and timing for FPGA bitstream loading rather than random-access memory usage.
Does the AT17LV002-10TQU support In-System Programming (ISP)?
Yes, the AT17LV002-10TQU supports ISP via its 2-wire serial interface when SER_EN is pulled low. Programming occurs at the same VCC supply voltage (3.3V or 5.0V); no external high-voltage programming signal is needed. Internal charge pumps generate required programming voltages, enabling field updates without device removal.
Can the AT17LV002-10TQU be used in a daisy-chain configuration?
Yes, the AT17LV002-10TQU supports daisy-chaining via its CEO (Chip Enable Output) pin. When the device finishes transmitting its entire bitstream, CEO goes low, enabling the CE input of the next AT17LV device in the chain. This allows seamless expansion beyond 2 Mbit without external sequencing logic.
What is the purpose of the READY pin on the AT17LV002-10TQU?
The READY pin on the AT17LV002-10TQU is an open-collector output that drives low during power-on reset and releases (goes high-impedance) once internal initialization completes. It provides a hardware handshake to delay FPGA startup until the EEPROM is ready, preventing configuration errors due to premature CCLK assertion.
Is the AT17LV002-10TQU compatible with Xilinx and Altera FPGAs?
Yes, the AT17LV002-10TQU is explicitly compatible with Xilinx XC3000/XC4000/XC5200/Spartan/Virtex families and Altera FLEX/APEX devices, as confirmed in the Atmel-2321J datasheet. Its timing parameters, pin functions, and serial protocol align directly with Master Serial configuration modes defined by both vendors.
