Product details
Overview
AT17LV010A-10PI from Atmel is a 1-Mbit (1,048,576 × 1-bit) FPGA configuration EEPROM designed for serial loading of SRAM-based FPGAs including Altera FLEX® and APEX™, Xilinx Spartan® and Virtex®, Lucent ORCA®, and Motorola MPA1000 devices. It operates at 3.3V (±10%) or 5.0V (±10% industrial), supports in-system programming via 2-wire bus, and features programmable reset polarity and cascading capability for multi-device configurations.
For engineers reviewing the AT17LV010A-10PI datasheet, AT17LV010A-10PI pinout, AT17LV010A-10PI application, or AT17LV010A-10PI equivalent, key selection criteria include industrial temperature range (-40°C to +85°C), TQFP/PLCC/PDIP package compatibility, 100,000 write cycles endurance, 90-year data retention at 85°C, and support for daisy-chained FPGA configuration with nCASC-driven auto-handoff.
Technical Context
The AT17LV010A-10PI implements a serial-access configuration memory architecture synchronized to DCLK rising edges, with address counter control governed by RESET/OE and nCS logic states. Its internal oscillator enables autonomous timing during power-up, and SER_EN toggles between FPGA loading mode (High) and 2-wire ISP programming mode (Low).
It supports cascaded operation via open-collector nCASC output that drives nCS of the next device in chain, and includes dual write-protection mechanisms: WP1 (dedicated input on 512K+/010/002 variants) and WP (pin-shared on smaller densities). The READY signal provides power-on reset status indication with external pull-up.

Pinout & Package
AT17LV010A-10PI is available in 32-lead TQFP (32A), 20-lead PLCC (20J), and 8-lead PDIP (8P3) packages. Pin assignments are identical across all three packages per family design, enabling hardware reuse across prototyping (PDIP), volume production (TQFP), and legacy-compatible (PLCC) implementations.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| DATA | Bi-directional serial I/O | Three-state open-collector output during configuration; bidirectional for 2-wire ISP programming; connects directly to FPGA DIN. |
| DCLK | Configuration clock input/output | Rising edge increments address counter; driven by FPGA DCLK in master mode; outputs Low when disabled or in reset. |
| RESET/OE | Active-Low reset / Active-High output enable | Resets address counter and tri-states DATA when Low; polarity programmable to match FPGA reset logic (default: active-Low reset). |
| nCS | Chip select input (active Low) | Enables counter and DATA output when Low; determines master/slave role in cascade chain based on reset timing. |

FAQ
What is the maximum configuration clock frequency supported by AT17LV010A-10PI?
The AT17LV010A-10PI supports up to 15 MHz at 5V industrial supply and 10 MHz at 3.3V industrial supply. These values are specified in the AC Characteristics table under FMAX and reflect guaranteed timing margins for reliable bitstream delivery to SRAM FPGAs. Exceeding these frequencies may result in configuration errors or metastability on the DATA line.
Does AT17LV010A-10PI require an external programmer for initial configuration loading?
No, AT17LV010A-10PI supports in-system programming via its 2-wire serial interface (SER_EN and DATA pins), eliminating the need for external programmers in most deployments. Industry-standard programmers like Atmel's ATDH2225 ISP Cable or compatible tools can be used, but for production, SER_EN is typically tied to VCC and configuration occurs automatically at power-up from the stored bitstream.
How does the nCASC pin function in a daisy-chained configuration with multiple AT17LV010A-10PI devices?
In a daisy chain, the nCASC output of one AT17LV010A-10PI goes Low after its final bit is transferred, which drives the nCS input of the next AT17LV010A-10PI device Low - enabling its DATA output and address counter. This handoff is automatic and requires no external logic, allowing seamless expansion of total configuration memory capacity across multiple devices.
What is the purpose of the READY pin on AT17LV010A-10PI, and how should it be used?
The READY pin on AT17LV010A-10PI is an open-collector output driven Low during power-on reset and released (high-impedance) once VCC stabilizes. It must be pulled up externally (e.g., 4.7 kΩ to VCC) to generate a clean logic-high signal. This signal can synchronize FPGA startup or enable downstream power rails only after the configurator is fully operational.
Can AT17LV010A-10PI be used with both 3.3V and 5V FPGA systems?
Yes, AT17LV010A-10PI is explicitly rated for dual-supply operation: 3.3V ±10% or 5.0V ±10% (industrial). Its VIH/VIL thresholds and output drive strength are validated across both voltages, and it maintains full functionality - including cascading, ISP, and reset polarity programming - regardless of selected VCC. This eliminates level-shifting requirements in mixed-voltage FPGA systems.
