Product details
Overview
AT17LV512-10PI from Microchip Technology (formerly Atmel) is a 512-Kbit serial FPGA configuration EEPROM designed for master-serial mode loading of SRAM-based FPGAs. It supports dual-voltage operation (3.3V ±10% or 5.0V ±10%), offers programmable reset polarity, and provides cascading capability via CEO output. It is used in industrial-grade FPGA systems requiring reliable, nonvolatile configuration storage with low-power standby.
For engineers reviewing the AT17LV512-10PI datasheet, AT17LV512-10PI pinout, AT17LV512-10PI application, or AT17LV512-10PI equivalent, key selection criteria include industrial temperature range (–40°C to +85°C), 8-lead PDIP package compatibility, CEO-enabled daisy-chaining, ISP support via two-wire bus, and verified interoperability with Xilinx XC4000/XC5200, Altera FLEX/APEX, and Atmel AT40K/AT94K devices.
Technical Context
The AT17LV512-10PI implements a serial memory architecture optimized for FPGA configuration sequencing, using a synchronous clock-driven address counter and tri-state DATA output controlled by CE and RESET/OE. Its CEO output enables automatic handoff between cascaded EEPROMs during multi-FPGA or high-density configuration loads.
It operates in two distinct modes: FPGA loading mode (SER_EN = High) and ISP programming mode (SER_EN = Low). In loading mode, it responds to FPGA-generated CCLK and CE signals; in ISP mode, it accepts two-wire serial commands for in-system reprogramming without removing the device from the board.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 524,288 × 1-bit (512 Kbit) - sufficient to configure mid-range SRAM FPGAs such as Xilinx Spartan or Altera FLEX10K. |
| Operating voltage | 3.3 V ±10% or 5.0 V ±10% - supports legacy 5V and modern 3.3V FPGA I/O domains without level-shifting. |
| Temperature range | –40°C to +85°C - qualified for industrial environments including factory automation and outdoor telecom equipment. |
| Write endurance | 100,000 cycles - enables field firmware updates and reconfiguration during product lifecycle. |
| Data retention | 90 years at 85°C - ensures long-term reliability in unattended embedded systems. |
| Max clock frequency | 15 MHz at 3.3V (industrial) - enables fast configuration startup time (<10 ms for full 512 Kbit load at 15 MHz). |
| Standby current | 100 µA (industrial, 3.3V) - minimizes power draw when FPGA is held in reset or not actively loading. |
Pinout & Package
AT17LV512-10PI is supplied in an 8-lead plastic dual in-line package (PDIP), 0.300" wide, with standard through-hole mounting. Pin 1 is marked by a notch or dot; the package footprint matches JEDEC MS-001 BA.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (DATA) | I/O bidirectional open-collector | Serial data path for configuration bitstream output to FPGA DIN; also used for two-wire ISP programming input. |
| 2 (CLK) | Input | Drives internal address/bit counter; synchronized to FPGA CCLK; determines configuration speed and timing margins. |
| 3 (RESET/OE) | Input | Programmable active-Low reset / active-High output enable; controls DATA driver state and address counter reset. |
| 4 (CE) | Input | Chip enable (active Low); enables CLK counting and DATA output; asserts standby mode when High. |
| 5 (GND) | Power | Ground reference; requires 0.2 µF decoupling capacitor near VCC pin per datasheet recommendation. |
| 6 (CEO) | Output | Chip Enable Output (active Low); signals end-of-data to next cascaded EEPROM's CE input for seamless daisy-chain operation. |
| 7 (SER_EN) | Input | Serial enable (High = FPGA loading mode; Low = two-wire ISP programming mode); must be tied to VCC unless reprogramming is required. |
| 8 (VCC) | Power | 3.3V or 5V supply input; supports mixed-voltage system integration without external regulators. |

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 capacity; only supports 3.3V operation; no CEO output; requires external pull-ups on DATA line. | Not suitable for daisy-chained configurations or 5V systems; limited to Xilinx-only designs. | Select when higher density is needed and 5V compatibility or cascading is unnecessary. |
| Microchip (Atmel) AT17LV256-10PI | 256-Kbit capacity; identical pinout and electrical specs except reduced memory size; same industrial temp rating and CEO functionality. | Applicable where FPGA configuration fits within 256 Kbit; lower cost but insufficient for larger Spartan or Virtex devices. | Select when BOM consolidation across AT17LV family is prioritized and memory requirement is ≤256 Kbit. |
Compared with XC18V02 and AT17LV256-10PI, the AT17LV512-10PI uniquely balances 512-Kbit density, dual-voltage support, industrial temperature operation, and CEO-enabled cascading-making it optimal for mid-complexity FPGA systems requiring field-upgradable, robust configuration storage.

FAQ
What is the primary function of the AT17LV512-10PI in an FPGA-based system?
The AT17LV512-10PI serves as a dedicated serial configuration EEPROM that stores and delivers the bitstream required to initialize SRAM-based FPGAs during power-up or reset. It operates in Master Serial mode, synchronizing directly with the FPGA's CCLK signal and driving the DIN pin. The AT17LV512-10PI eliminates the need for external controllers or complex boot logic, enabling autonomous, repeatable FPGA configuration in industrial and telecom applications.
Does the AT17LV512-10PI support in-system programming (ISP), and how is it enabled?
Yes, the AT17LV512-10PI supports in-system programming via a two-wire serial interface. ISP is enabled by pulling the SER_EN pin Low, which places the device into programming mode. In this mode, the DATA and CLK pins accept serial commands to erase, program, or verify memory contents-all while the device remains soldered on the PCB. The AT17LV512-10PI does not require external programming voltage; internal charge pumps generate necessary levels from VCC alone.
How does the CEO pin on the AT17LV512-10PI facilitate cascaded FPGA configurations?
The CEO (Chip Enable Output) pin on the AT17LV512-10PI goes Low when its internal address counter reaches the final memory location, signaling completion of its configuration data stream. In a daisy chain, this CEO output connects directly to the CE input of the next AT17LV512-10PI (or compatible device), automatically enabling it to begin outputting its own bitstream. This hardware handoff ensures seamless, glitch-free multi-device configuration without FPGA intervention-critical for large-scale or multi-FPGA systems.
Can the AT17LV512-10PI be used with both 3.3V and 5V FPGAs, and what design considerations apply?
Yes, the AT17LV512-10PI is explicitly rated for both 3.3V (±10%) and 5.0V (±10%) operation, making it compatible with mixed-voltage FPGA platforms. When interfacing with 3.3V FPGAs, ensure VCC is regulated to 3.3V ±0.33V; for 5V FPGAs, use 5.0V ±0.5V. Input thresholds (VIH/VIL) are compatible with both logic families, and output drive strength meets specifications across both rails. No level-shifting circuitry is required, simplifying board layout and reducing component count.
What is the significance of the "-10PI" suffix in the AT17LV512-10PI ordering code?
The "-10PI" suffix denotes three critical attributes: "10" indicates a maximum access time of 10 ns (reflected in AC timing parameters like TCAC and TOE), "P" specifies the 8-lead PDIP package, and "I" confirms industrial temperature grade (–40°C to +85°C). This distinguishes it from commercial-grade variants (e.g., -10PC) and alternate packages like LAP (-10CU) or PLCC (-10JI). The AT17LV512-10PI is therefore optimized for timing-critical, thermally demanding industrial deployments.
