Product details
Overview
AT17LV020-10JC from Microchip Technology (formerly Atmel) is a 2-Mbit serial EEPROM FPGA configuration memory in 20-pin PLCC package, operating at 3.3V ±10%, supporting Master Serial Mode configuration of Xilinx XC4000/XC5200/Spartan/Virtex, Altera FLEX®, and ORCA® FPGAs with programmable reset polarity and cascading capability.
For engineers reviewing the AT17LV020-10JC datasheet, AT17LV020-10JC pinout, AT17LV020-10JC application, or AT17LV020-10JC equivalent, key selection considerations include 3.3V operation, PLCC-20 packaging, 12.5 MHz max clock frequency (commercial), READY pin for power-up synchronization, and in-system programmability via 2-wire bus.
Technical Context
The AT17LV020-10JC implements a serial-access EEPROM architecture optimized for FPGA configuration loading in Master Serial Mode, where the FPGA's CCLK drives the device's CLK input and DATA output feeds the FPGA's DIN. Its internal address counter advances on each CLK edge and resets upon active RESET/OE assertion.
It supports two configuration interface modes: Condition 1 (FPGA CON drives both CE and RESET/OE, requiring active-High reset polarity) and Condition 2 (FPGA CON drives CE, INIT drives RESET/OE, requiring active-Low reset polarity), with programmable polarity eliminating external inverters. Cascading uses CEO to chain multiple devices for larger configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 2,097,152 × 1 bit - sufficient to configure Xilinx XC4000, XC5200, Spartan, and Virtex FPGAs in single-device mode. |
| Supply voltage | 3.3 V ±10% - compatible with 3.3V FPGA I/O domains and low-power system designs. |
| Max clock frequency | 12.5 MHz (commercial), 7.5 MHz (industrial/military) - sets upper bound on configuration speed and timing margin for CCLK-driven loading. |
| Standby current | 0.2 mA at 3.3V - enables ultra-low power retention during FPGA idle or sleep states. |
| Reset polarity | Programmable active-High or active-Low - allows direct interface with FPGA INIT/CON pins without external logic. |
| READY function | Open-collector indicator driven Low during power-on reset - synchronizes FPGA configuration start with stable VCC. |
| Interface protocol | 2-wire serial bus for in-system programming - enables field updates without removing device from PCB. |
Pinout & Package
AT17LV020-10JC is housed in a 20-lead Plastic J-leaded Chip Carrier (PLCC) package, RoHS-compliant and rated for commercial temperature range (0°C to +70°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| DATA (Pin 13) | Bi-directional I/O | Three-state open-collector output during configuration; bidirectional data path during 2-wire ISP programming. |
| CLK (Pin 4) | Input | Drives internal address/bit counter; synchronized to FPGA CCLK for deterministic bit-stream delivery. |
| RESET/OE (Pin 6) | Input | Programmable polarity input that resets address counter and enables DATA driver when asserted with CE. |
| CE (Pin 8) | Input | Chip Enable controlling read access and standby entry; high level forces <0.2 mA standby current. |
| CEO (Pin 14) | Output | Chip Enable Output used to cascade multiple AT17LV020-10JC devices; asserts Low after final bit read. |
| READY (Pin 15) | Output | Open-collector power-good indicator; driven Low during internal POR, released when VCC stabilizes. |
| SER_EN (Pin 17) | Input | Serial Enable; must be High for FPGA configuration, Low to enter 2-wire ISP programming mode. |
| VCC (Pin 20) | Power | 3.3V ±10% supply; powers all internal logic and EEPROM array; requires local 0.2 µF decoupling. |
| GND (Pin 10) | Ground | Reference return path; must be connected to system ground plane with low-inductance layout. |
Key Features
| Feature | Design Value |
|---|---|
| In-system programmability | Enables field reprogramming via 2-wire bus without device removal, reducing maintenance downtime and enabling firmware updates. |
| Cascadable CEO output | Allows daisy-chaining multiple AT17LV020-10JC units to support larger FPGA configurations or multi-FPGA systems without external glue logic. |
| Programmable reset polarity | Eliminates need for external inverters by allowing user to match FPGA INIT/CON signal polarity (active-High or active-Low) via EEPROM byte programming. |
| System-friendly READY pin | Provides hardware-synchronized power-up signal to FPGA, ensuring configuration begins only after VCC reaches valid operating range. |
| Low-power standby mode | Draws only 0.2 mA at 3.3V when CE is high, minimizing system power budget during FPGA idle or partial-reconfiguration pauses. |
Applications
| Industrial PLC Configuration | Xilinx Spartan-Based Edge AI Controller |

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 serial PROM; 3.3V operation; no READY pin; fixed active-Low reset; not in-system programmable. | Limited to Xilinx-only ecosystems; lacks cascading CEO and programmable reset polarity. | Select when using only Xilinx FPGAs and requiring lowest BOM cost without field update capability. |
| Microchip (Atmel) AT17LV010-10JC | 1-Mbit density; identical PLCC-20 package, 3.3V supply, and pinout; same AC/DC specs except memory size. | Suitable only for smaller FPGAs (e.g., XC3000, AT40K); insufficient for XC4000+ or Spartan-II+ families. | Select when configuration image fits within 1 Mbit and board layout reuse of PLCC-20 footprint is required. |
Compared with XC18V02 and AT17LV010-10JC, the AT17LV020-10JC uniquely combines 2-Mbit capacity, programmable reset polarity, READY signaling, and cascading CEO-enabling robust, vendor-flexible, and field-upgradable FPGA configuration in industrial and telecom environments.

FAQ
What is the operating voltage range for AT17LV020-10JC?
The AT17LV020-10JC operates at 3.3 V ±10%, meaning its valid supply range is 2.97 V to 3.63 V. This matches standard 3.3V FPGA I/O rails and ensures compatibility with industrial power supplies meeting tight tolerance requirements. The device draws only 0.2 mA in standby at this voltage, making it suitable for low-power embedded systems. AT17LV020-10JC does not support 5V operation-use AT17C020-10JC for 5V systems.
How does the READY pin function in AT17LV020-10JC?
The READY pin on AT17LV020-10JC is an open-collector output that is actively driven Low during internal power-on reset and tri-stated (released) once VCC stabilizes within specification. It provides hardware-level synchronization so the FPGA delays configuration until power is valid. A 4.7 kΩ pull-up resistor is recommended on this pin. Unlike general-purpose reset signals, READY reflects only the AT17LV020-10JC's internal POR state-not system-wide reset conditions.
Can AT17LV020-10JC be programmed in-circuit?
Yes, AT17LV020-10JC supports in-system programming (ISP) via its 2-wire serial interface when SER_EN is pulled Low. Programming occurs at the normal VCC supply (3.3V), with all high-voltage generation handled internally-no external VPP required. Industry-standard programmers compatible with Atmel's ATDH2200E protocol can reprogram AT17LV020-10JC without removal from the PCB, enabling field updates and configuration revisions.
What FPGA families is AT17LV020-10JC officially compatible with?
AT17LV020-10JC is explicitly validated for Xilinx XC3000, XC4000, XC5200, Spartan®, and Virtex® FPGAs; Altera FLEX® devices; Lucent ORCA® FPGAs; and Atmel AT6000 and AT40K series. Compatibility is based on Master Serial Mode timing, pin mapping, and configuration protocol alignment-not just voltage matching. It is not qualified for newer 7-series or UltraScale FPGAs, which require different configuration architectures.
What is the purpose of the CEO pin on AT17LV020-10JC?
The CEO (Chip Enable Output) pin on AT17LV020-10JC enables daisy-chain cascading of multiple configuration EEPROMs. After the last bit is read, CEO goes Low, disabling the current device's DATA output and enabling the next device's DATA driver in the chain. This allows seamless expansion beyond 2 Mbit-for example, configuring large Virtex FPGAs or multi-FPGA systems-without external logic or microcontroller intervention. CEO behavior is defined in the AT17LV020-10JC datasheet AC characteristics table.
