Product details
Overview
AT17LV512A-10PI from Atmel is a 512-kbit (2,097,152 × 1-bit) FPGA configuration EEPROM designed to store and serially load bitstreams into SRAM-based FPGAs including Altera FLEX® and APEX™, Xilinx Spartan® and Virtex®, and Lucent ORCA® 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 AT17LV512A-10PI datasheet, AT17LV512A-10PI pinout, AT17LV512A-10PI application, or AT17LV512A-10PI equivalent, key selection criteria include industrial temperature support (−40°C to +85°C), 8-lead PDIP package compatibility with Altera EEPROMs, standby current ≤100 µA at 3.3V, and verified cascading operation with nCASC/nCS daisy-chain control.
Technical Context
The AT17LV512A-10PI implements a serial master configuration interface for SRAM FPGAs, using DCLK-driven address counting and DATA output synchronized to rising clock edges. Its RESET/OE pin serves dual roles-active-Low reset and active-High output enable-with polarity programmable during programming.
Cascading is enabled via nCASC (active-Low cascade select output) tied to nCS of the next device, allowing seamless expansion beyond 512 kbits. SER_EN must be held High during FPGA loading; pulling it Low enables 2-wire ISP mode, with internal charge pumps generating programming voltages from VCC alone.

FAQ
What is the operating voltage range for AT17LV512A-10PI?
The AT17LV512A-10PI supports two nominal supply voltages: 3.3V ±10% (3.0V–3.6V) and 5.0V ±10% (4.5V–5.5V), both qualified across the industrial temperature range of −40°C to +85°C. This dual-voltage capability allows direct replacement in legacy 5V FPGA systems and newer 3.3V designs without level-shifting circuitry. The device internally generates required programming voltages during ISP.
Does AT17LV512A-10PI support in-system programming (ISP)?
Yes, AT17LV512A-10PI supports in-system programming via a 2-wire serial interface using the SER_EN and DATA/DCLK pins. When SER_EN is pulled Low, the device enters ISP mode and accepts programming commands directly from a host controller or programmer. No external high-voltage supply is needed - all programming voltages are generated internally from VCC. This enables field firmware updates without removing the device from the PCB.
Which FPGA families is AT17LV512A-10PI compatible with?
AT17LV512A-10PI is explicitly validated for Altera FLEX® and APEX™ FPGAs, Xilinx XC3000™, XC4000™, XC5200™, Spartan®, and Virtex® families, Lucent ORCA® FPGAs, and Motorola MPA1000 devices. Its serial interface and timing parameters align with Master Serial configuration protocols. Compatibility is confirmed in Atmel's Device Selection Guide and supported by pin-for-pin equivalence with Altera EPC1441 for 512-kbit applications.
What is the purpose of the WP1 pin on AT17LV512A-10PI?
The WP1 pin on AT17LV512A-10PI is a write-protect input used during in-system programming to prevent accidental modification of protected memory blocks. It is inactive by default due to an internal pull-down resistor and is only functional when SER_EN is Low. WP1 is exclusive to the AT17LV512A/010A/002A family members and is not present on lower-density variants like AT17LV256A.
How does cascading work with AT17LV512A-10PI in multi-FPGA systems?
Cascading with AT17LV512A-10PI uses the nCASC (pin 7) output, which goes Low when the internal address counter reaches its maximum value. This signal is connected to the nCS (pin 5) input of the next AT17LV512A-10PI or compatible device in the chain. Upon detecting the Low nCS, the downstream device enables its DATA output and begins streaming its stored bitstream - enabling seamless expansion beyond 512 kbits without external control logic.
