Product details
Overview
AT17LV020-10JI from Microchip Technology (formerly Atmel) is a 2-Mbit serial EEPROM FPGA configuration memory in 20-pin PLCC packaging, 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 AT17LV020-10JI datasheet, AT17LV020-10JI pinout, AT17LV020-10JI application, or AT17LV020-10JI equivalent, key selection criteria include 3.3V operation, industrial temperature range (−40°C to +85°C), PLCC-20 package compatibility, READY pin for power-up synchronization, and in-system programmability via 2-wire bus.
Technical Context
The AT17LV020-10JI implements a serial-access, nonvolatile memory architecture optimized for FPGA configuration loading in Master Serial Mode, where the FPGA's CCLK drives the EEPROM's CLK input and DATA output feeds the FPGA's DIN. It uses internal address counters synchronized to CE and RESET/OE control signals, with programmable reset polarity enabling flexible system-level reset coordination.
It supports cascading via CEO output to enable multi-FPGA daisy-chain configurations or extended memory capacity, and includes a system-friendly open-collector READY pin that asserts low during power-on reset and releases upon stable VCC - directly interfacing with FPGA INIT/CON logic without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 2,097,152 × 1 bit - sufficient to configure single Xilinx XC4000 or multiple smaller FPGAs in Master Serial Mode |
| Supply voltage | 3.3 V ±10% - compatible with 3.3V FPGA I/O domains and eliminates level-shifting requirements |
| Operating temperature | −40°C to +85°C - qualified for industrial environments without derating |
| Max clock frequency | 12.5 MHz (commercial), 7.5 MHz (industrial) - sets upper bound on configuration speed in synchronous serial load |
| Standby current | 0.2 mA - enables low-power system sleep states while retaining configuration data |
| Reset polarity | Programmable active-high or active-low - allows direct interface with FPGA INIT/CON pins under diverse reset architectures |
| Interface protocol | 2-wire serial (SER_EN-controlled) - enables in-system reprogramming without removing device from PCB |
Pinout & Package
Package: 20-lead Plastic J-leaded Chip Carrier (PLCC-20), surface-mount, JEDEC MS-026 compliant, with 0.5-inch body width and 0.05-inch lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| DATA (Pin 13) | Bi-directional serial I/O | Drives FPGA DIN during configuration; used for 2-wire programming when SER_EN = Low |
| CLK (Pin 4) | Input clock | Synchronizes internal address/bit counter; driven by FPGA CCLK in Master Serial Mode |
| RESET/OE (Pin 6) | Programmable control input | Resets internal address counter when asserted; polarity configurable per EEPROM byte |

| CEO (Pin 14) | Cascade enable output | Asserts Low after last bit read to enable next EEPROM in daisy chain |
| READY (Pin 15) | Open-collector status indicator | Signals stable VCC to FPGA - driven Low during power-on reset, tri-stated thereafter |
| SER_EN (Pin 17) | Serial programming enable | Must be High for FPGA configuration; Low enables 2-wire ISP mode |
| VCC (Pin 20) | Power supply | 3.3V ±10% nominal; powers all logic and EEPROM array |
| GND (Pin 10) | Ground reference | Reference for all I/O and internal circuitry; requires local 0.2 µF decoupling |
Key Features
| Feature | Design Value |
|---|---|
| In-system programmability | Enables field firmware updates via 2-wire bus without socket removal or dedicated programmer hardware |
| Cascadable CEO output | Allows daisy-chaining multiple AT17LV020-10JI devices to support larger FPGAs or multi-device systems |

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-only; no programmable reset polarity; no READY pin; no cascading CEO | Limited to Xilinx FPGA ecosystems; lacks system-level power sequencing support | Select when targeting Xilinx-only designs and requiring tighter integration with Xilinx tools |
| Microchip AT17LV010-10JI | 1-Mbit density; otherwise identical pinout, voltage, temperature, and feature set | Suitable only for smaller FPGAs (e.g., XC3000, early XC4000) with sub-1Mbit bitstreams | Select when configuration image fits in 1 Mbit and cost optimization is prioritized over future scalability |
Compared with XC18V02 and AT17LV010-10JI, the AT17LV020-10JI uniquely combines industrial temperature support, programmable reset polarity, READY pin for power sequencing, and CEO-based cascading - making it the only option among the three that supports robust, multi-vendor FPGA configuration in harsh environments with upgrade path flexibility.

FAQ
What is the primary function of the AT17LV020-10JI in an FPGA-based system?
The AT17LV020-10JI serves as a dedicated serial configuration memory that stores and loads bitstream data into Field Programmable Gate Arrays during power-up or reconfiguration. Its 2-Mbit capacity supports Xilinx XC4000/XC5200/Spartan, Altera FLEX®, and ORCA® FPGAs in Master Serial Mode. The AT17LV020-10JI interfaces directly with FPGA CCLK and DIN pins, eliminating need for external controllers or parallel memory buses.
How does the READY pin on the AT17LV020-10JI improve system reliability?
The READY pin is an open-collector output that remains low during power-on reset and transitions to high-impedance once VCC stabilizes within specification. This provides FPGA logic with a deterministic power-good signal to coordinate configuration start time, preventing metastability or partial configuration errors. A 4.7 kΩ pull-up resistor is recommended. The AT17LV020-10JI READY functionality removes dependency on external supervisor ICs in industrial designs.
Can the AT17LV020-10JI be reprogrammed in-circuit, and what interface is required?
Yes, the AT17LV020-10JI supports in-system programming (ISP) via a 2-wire serial interface activated by pulling SER_EN low. Programming occurs at normal VCC (3.3V) without external high-voltage supplies - internal charge pumps generate required programming voltages. Industry-standard programmers or Microchip's ATDH2200E system can perform ISP. The AT17LV020-10JI retains full read/write capability throughout its endurance rating of 100,000 cycles.
What is the significance of programmable reset polarity on the AT17LV020-10JI?
Programmable reset polarity allows the AT17LV020-10JI's RESET/OE pin to be configured as either active-high or active-low via internal EEPROM bytes - matching diverse FPGA INIT/CON signaling conventions without external inverters. This ensures correct address counter reset timing during FPGA abort/restart sequences. The AT17LV020-10JI supports both Condition 1 (CON-driven CE+RESET/OE) and Condition 2 (separate CON and INIT connections) per Atmel application notes.
Is the AT17LV020-10JI pin-compatible with other members of the AT17 family?
Yes, the AT17LV020-10JI uses the standard 20-pin PLCC (20J) package and shares identical pinout, signal definitions, and electrical characteristics with AT17C020-10JI, AT17LV010-10JI, and other AT17-series configurators. This enables direct substitution across voltage grades (3.3V vs. 5V) and densities (1-Mbit vs. 2-Mbit) without PCB changes - a key design advantage documented in Atmel's ordering information tables.
