Product details
Overview
AT17LV512-10PC from Atmel is a 512-Kbit (524,288 × 1-bit) serial EEPROM FPGA configuration memory supporting both 3.3V and 5.0V operation, featuring in-system programmability via two-wire bus, programmable reset polarity, and cascading capability via CEO output for multi-FPGA systems. It targets SRAM-based FPGA configuration in industrial control and communications infrastructure.
For engineers reviewing the AT17LV512-10PC datasheet, AT17LV512-10PC pinout, AT17LV512-10PC application, or AT17LV512-10PC equivalent, key selection factors include its 512-Kbit density, dual-voltage support, CEO-driven daisy-chain capability, low-power standby mode (100 µA industrial), and compatibility with Xilinx XC4000/XC5200 and Altera FLEX/APEX families.
Technical Context
The AT17LV512-10PC implements a serial master-mode configuration interface synchronized to an external FPGA CCLK signal, using CE, RESET/OE, and SER_EN to manage address counter enablement, reset behavior, and ISP entry. Its CEO output enables hardware-level chaining of multiple configurators without external logic.
It supports programmable reset polarity (active-low RESET or active-high OE), write protection via WP1/WP2 inputs during programming, and operates across -40°C to +85°C industrial temperature range with 90-year data retention at 85°C. The device uses internal charge-pump circuitry for programming at standard VCC levels.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 524,288 × 1-bit (512 Kbit) - sufficient to configure mid-density SRAM FPGAs like Xilinx Spartan or Altera FLEX10K. |
| Supply voltage | 3.3V ±10% or 5.0V ±10% - enables drop-in use in legacy 5V and modern 3.3V FPGA systems without level-shifting. |
| Max clock frequency | 15 MHz at 3.3V (commercial) - supports fast configuration loading aligned with FPGA CCLK timing budgets. |
| Standby current | 100 µA (industrial, 3.3V) - minimizes system power draw during FPGA idle or sleep states. |

Pinout & Package
AT17LV512-10PC is available in 8-lead PDIP (8P3) package, measuring 0.300" wide with 0.100" lead pitch, compatible with standard through-hole PCB assembly and socketing. Pinout matches industry-standard 8-pin serial EEPROM layout with dedicated CEO output for cascading.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 DATA | I/O bidirectional open-collector | Serial data path for configuration bitstream transfer to FPGA DIN; tri-stated when CE or RESET/OE inactive. |
| 2 CLK | Input | Driven by FPGA CCLK; increments internal address counter on rising edge during configuration read. |
| 3 RESET/OE | Input | Programmable polarity input controlling address counter reset (active-low) and DATA output enable (active-high). |
| 4 CE | Input | Chip enable (active-low); disables counters and forces standby mode when high, reducing current to 100 µA. |
| 5 GND | Power | Ground reference; requires 0.2 µF decoupling capacitor near VCC pin per design guidelines. |
| 6 CEO | Output | Chip Enable Output (active-low); signals end-of-data to next cascaded AT17LV device in daisy-chain topology. |
| 7 SER_EN | Input | Serial enable (high during normal config, low to enter two-wire ISP mode); tied to VCC in non-programming applications. |
| 8 VCC | Power | 3.3V or 5.0V supply input; accepts ±10% tolerance, enabling robust operation across voltage rail variations. |
Key Features
| Feature | Design Value |

FAQ
What is the memory capacity and organization of the AT17LV512-10PC?
The AT17LV512-10PC provides 524,288 × 1-bit (512 Kbit) of serial EEPROM storage, organized as a linear bitstream for sequential FPGA configuration loading. It does not support byte-addressable random access; data is read out in strict serial order starting from address zero upon power-up or RESET/OE assertion.
Does the AT17LV512-10PC support in-system programming, and how is it enabled?
Yes, the AT17LV512-10PC supports in-system programming via a two-wire serial interface. Programming mode is entered by driving the SER_EN pin low while applying valid VCC; DATA and CLK then serve as bidirectional serial bus lines. Standard industry programmers (e.g., Atmel ATDH2225 ISP Cable) or FPGA-controlled sequences can perform writes.
How does the CEO pin function in a daisy-chained configuration using multiple AT17LV512-10PC devices?
The CEO pin of the AT17LV512-10PC goes active-low when its internal address counter reaches the final bit. In a daisy chain, this CEO signal drives the CE input of the next AT17LV512-10PC, enabling its DATA output automatically-ensuring continuous bitstream flow without FPGA intervention or external timing logic.
What are the supported operating voltage ranges and temperature grades for the AT17LV512-10PC?
The AT17LV512-10PC operates from 3.0V to 3.6V or 4.5V to 5.5V (±10% at 5V), supporting both 3.3V and 5.0V systems. The "-10PC" suffix denotes commercial grade (0°C to +70°C); industrial variants (e.g., AT17LV512-10PI) extend operation to -40°C to +85°C with identical electrical specs except for increased standby current.
Can the AT17LV512-10PC be used with Xilinx Virtex FPGAs, and what interface signals are required?
Yes, the AT17LV512-10PC is explicitly compatible with Xilinx Virtex FPGAs in Master Serial mode. Required connections are: AT17LV512-10PC DATA → FPGA DIN, CLK ← FPGA CCLK, CE ← FPGA INIT_B (or dedicated CE control), RESET/OE ← FPGA PROGRAM_B, and CEO → CE of next device if cascading.
