Product details
Overview
AT17LV512A-10PC from Atmel is a 512-Kbit (524,288 × 1-bit) serial FPGA configuration EEPROM designed for Altera FLEX® and APEX™ FPGAs, operating at 3.3V ±10% or 5.0V ±10%, featuring in-system programmability via 2-wire bus, programmable reset polarity, and cascading support for multi-device configurations in industrial (-40°C to +85°C) environments.
For engineers reviewing the AT17LV512A-10PC datasheet, AT17LV512A-10PC pinout, AT17LV512A-10PC application, or AT17LV512A-10PC equivalent, key selection criteria include voltage compatibility (3.3V/5V), industrial temperature rating, cascading capability via nCASC/nCS, standby current ≤100 µA at 3.3V, and pin-compatible availability in 8-lead PDIP and 20-lead PLCC packages.
Technical Context
The AT17LV512A-10PC implements a serial master configuration interface for SRAM-based FPGAs, using DCLK-driven address counting and tri-state DATA output synchronized to RESET/OE and nCS control logic. Its internal oscillator enables autonomous timing during configuration without external clock dependency when SER_EN is high.
It supports daisy-chained operation via nCASC output driving the nCS input of subsequent devices, with programmable reset polarity and write protection via WP1. The device enters low-power standby (<100 µA at 3.3V) when nCS is high and maintains data retention up to 90 years at 85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory density | 524,288 × 1-bit (512 Kbit) - sufficient for mid-range Altera FLEX/APEX FPGA bitstreams |
| Supply voltage | 3.3V ±10% or 5.0V ±10% - dual-voltage support enables drop-in replacement across legacy and modern FPGA systems |
| Operating temperature | -40°C to +85°C - qualified for industrial-grade embedded and telecom infrastructure applications |
| Standby current | ≤100 µA at 3.3V - enables low-power system sleep modes without compromising configuration integrity |

Pinout & Package
AT17LV512A-10PC is available in 8-lead PDIP (8P3) and 20-lead PLCC (20J) packages. Pin functions are validated per Atmel datasheet 2322D–CNFG–07/02, with WP1 and READY present only on this variant (not on smaller-density AT17LV65A/128A/256A).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| DATA | Bi-directional serial I/O | Three-state open-collector output during FPGA configuration; bidirectional for ISP programming |
| DCLK | Configuration clock input/output | Rising edge increments address counter; driven low by device when not actively transferring data |
| RESET/OE | Reset and output enable | Active-low reset resets address counter; active-high OE enables DATA output; polarity programmable |
| nCS | Chip select | Active-low enables counter and DATA driver; determines master/slave role in cascaded chains |
| nCASC | Cascade select output | Active-low signal indicating end-of-data; used to trigger next device in daisy-chain |
| WP1 | Write protect input | Enables memory block protection during ISP; internal pull-down defaults to disabled state |
| READY | Power-on reset indicator | Open-collector output held low during power-up initialization; requires external 4.7 kΩ pull-up |
| SER_EN | Serial programming enable | High during FPGA loading; low to enter 2-wire ISP mode; tied to VCC for non-ISP use |
Key Features
| Feature | Design Value |
|---|---|
| In-system programmability | 2-wire serial interface (SER_EN + DATA/DCLK) eliminates need for dedicated programmers in deployed systems |
| Cascadable architecture | nCASC output directly drives nCS of next device, enabling seamless expansion beyond 512 Kbit without external logic |
| Programmable reset polarity | User-configurable RESET/OE behavior ensures compatibility with diverse FPGA reset schemes (e.g., Altera vs. Xilinx) |
| Low-power standby | 100 µA max ICCS at 3.3V allows integration into battery-backed or energy-constrained FPGA systems |
| Industrial reliability | 90-year data retention at 85°C and 100,000 write cycles meet extended-life requirements for industrial automation controllers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar FPGA configuration memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT17LV512A-10JC | Same 512-Kbit density and pinout, but in 20-lead PLCC (20J) package instead of 8-lead PDIP (8P3); identical electrical specs and timing | Preferred for surface-mount PCBs with space constraints; requires different footprint and reflow profile | Select AT17LV512A-10JC for automated SMT assembly; AT17LV512A-10PC remains optimal for through-hole prototyping or legacy board upgrades |
| EPC1441 | Altera-branded 512-Kbit configuration device; pin-compatible with AT17LV512A in 8P3/20J packages but lacks WP1 and READY pins; no programmable reset polarity | Designed exclusively for Altera toolchain integration; limited to Altera FLEX/APEX families without cross-vendor flexibility | Choose EPC1441 only when locked to Altera Quartus flow and no cascading or ISP is required; AT17LV512A-10PC offers broader FPGA vendor support and field-programmability |
Compared with AT17LV512A-10JC and EPC1441, the AT17LV512A-10PC uniquely combines through-hole PDIP packaging, industrial temperature rating, cascading capability via nCASC, and in-system programmability - making it the only option supporting field-upgradable FPGA configurations in ruggedized industrial hardware.

FAQ
What is the maximum clock frequency supported by AT17LV512A-10PC during FPGA configuration?
The AT17LV512A-10PC supports up to 15 MHz at 3.3V in commercial temperature range and 10 MHz at 3.3V in industrial range (-40°C to +85°C), as specified in the AC Characteristics table. This ensures reliable synchronization with FPGA master serial mode clocks while maintaining setup/hold timing margins for robust bitstream loading.
Does AT17LV512A-10PC support cascading with other configuration EEPROMs?
Yes, AT17LV512A-10PC supports cascading via its dedicated nCASC output pin, which asserts low upon reaching end-of-memory and can directly drive the nCS input of a downstream AT17LV-series device. This enables seamless expansion beyond 512 Kbit without external glue logic or controller intervention.
What package options are available for AT17LV512A-10PC?
AT17LV512A-10PC is offered in two package variants: 8-lead PDIP (8P3) and 20-lead PLCC (20J). The "-10PC" suffix specifically denotes the 8-lead PDIP package with commercial temperature range; the "-10JC" variant uses the same die in PLCC packaging.
How does the programmable reset polarity feature work in AT17LV512A-10PC?
The AT17LV512A-10PC allows users to program the RESET/OE pin's logic polarity during initial programming - selecting whether it functions as active-low RESET or active-high OE. This is implemented by writing four specific EEPROM bytes and ensures compatibility with FPGA families that require opposite reset signaling conventions.
What is the standby current consumption of AT17LV512A-10PC at 3.3V?
AT17LV512A-10PC consumes ≤100 µA in standby mode at 3.3V when nCS is held high, as confirmed in the DC Characteristics table. This ultra-low quiescent current enables integration into power-sensitive systems such as battery-backed industrial controllers or portable FPGA development platforms.
