Product details
Overview
AT17LV512-10CI from Microchip Technology (formerly Atmel) is a 512-Kbit serial EEPROM FPGA configuration memory with industrial-grade temperature operation (–40°C to +85°C), supporting both 3.3V and 5.0V supply, in-system programmability via two-wire bus, and cascading capability via CEO output. It stores bitstream configuration data for SRAM-based FPGAs including Xilinx XC4000/XC5200/Spartan, Altera FLEX/APEX, and Atmel AT40K/AT94K devices.
For engineers reviewing the AT17LV512-10CI datasheet, AT17LV512-10CI pinout, AT17LV512-10CI application, or AT17LV512-10CI equivalent, key selection criteria include industrial temperature rating, 8-lead LAP package compatibility with SOIC footprints, programmable reset polarity, CEO-enabled daisy-chaining, and verified interoperability with major FPGA families' Master Serial mode.
Technical Context
The AT17LV512-10CI implements a serial-access configuration memory architecture synchronized to an external FPGA-provided clock (CLK), with tri-state DATA output controlled by CE and RESET/OE. Its address counter auto-resets on power-up and supports cascaded read-back via CEO output, enabling multi-device configuration chains without external logic.
It operates in two distinct modes: FPGA loading mode (SER_EN = High) and two-wire ISP programming mode (SER_EN = Low). In loading mode, it delivers configuration data directly to FPGA DIN using FPGA CCLK as timing reference; in ISP mode, it accepts programming commands over a dedicated two-wire interface with A2 device selection and internal voltage boosting.
Key Specifications

Pinout & Package
AT17LV512-10CI is packaged in an 8-lead Leadless Array Package (LAP), 6 mm × 6 mm × 1 mm body, pin-compatible with standard 8-lead SOIC footprints. The LAP package offers improved thermal performance (θJA = 135.71°C/W) and space efficiency versus PDIP or SOIC alternatives.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 DATA | I/O (Open-collector bi-directional) | Configuration data output to FPGA DIN; bidirectional during ISP programming; requires external pull-up in loading mode. |
| 2 CLK | Input | System clock input from FPGA CCLK; increments internal address/bit counter; defines configuration timing. |
| 3 RESET/OE | Input | Programmable active-Low reset / active-High output enable; resets address counter and tri-states DATA when asserted. |
| 4 CE | Input (active Low) | Chip enable; enables address counter and DATA driver when low; forces standby mode when high. |
| 5 VCC | Power | 3.3 V or 5.0 V supply; decoupling with 0.2 µF capacitor to GND required for noise immunity. |
| 6 SER_EN | Input | Serial enable; must be tied to VCC for FPGA loading; pulled low to enter two-wire ISP programming mode. |
| 7 CEO (A2) | Output / Input | Chip Enable Output (active Low) for daisy-chaining; also serves as A2 device select during ISP programming. |
| 8 GND | Ground | Reference ground; decoupling capacitor connection point; critical for signal integrity and power stability. |
Key Features
| Feature | Design Value |
|---|---|
| In-System Programmability (ISP) | Enables field firmware updates via two-wire interface without removing the device; eliminates need for socketed programming fixtures. |
| Cascadable CEO Output | Allows daisy-chained configuration of multiple FPGAs or higher-density arrays using single CCLK source and automatic handoff between devices. |
| Programmable Reset Polarity | Supports both active-Low RESET and active-High OE configurations via EEPROM byte programming - matches diverse FPGA pinout conventions. |
| Low-Power Standby Mode | Consumes only 100 µA at 3.3 V (industrial grade); reduces system power draw when configuration is complete and CE is deasserted. |
| Emulation of AT24CXXX EEPROMs | Provides drop-in compatibility with existing serial EEPROM infrastructure for test/debug setups or legacy design reuse. |

FAQ
What is the primary function of the AT17LV512-10CI in an FPGA-based system?
The AT17LV512-10CI serves as a serial configuration memory that stores and delivers bitstream data to SRAM-based FPGAs during power-up or reconfiguration. It operates in Master Serial mode, using the FPGA's CCLK signal to synchronize data transfer via the DATA pin. Its CEO output enables daisy-chaining for multi-FPGA systems, and its industrial temperature rating ensures reliability in demanding environments. The AT17LV512-10CI eliminates the need for external controllers in configuration sequencing.
Does the AT17LV512-10CI support both 3.3 V and 5.0 V operation, and how does this affect system design?
Yes, the AT17LV512-10CI supports both 3.3 V ±10% and 5.0 V ±5% (commercial) or ±10% (industrial) supply voltages. This dual-voltage capability allows direct integration into mixed-signal FPGA platforms - for example, pairing with 5 V legacy peripherals while powering a 3.3 V FPGA core. No level-shifting circuitry is required on the DATA, CLK, or control lines, simplifying board layout and reducing component count. The AT17LV512-10CI maintains full AC/DC specification compliance across both voltage domains.
How does the CEO pin on the AT17LV512-10CI enable cascaded FPGA configuration?
The CEO (Chip Enable Output) pin on the AT17LV512-10CI goes active-Low when its internal address counter reaches the final memory location. In a daisy chain, this CEO signal connects directly to the CE input of the next AT17LV512-10CI (or compatible device), automatically enabling it to begin outputting its stored bitstream. This handoff occurs synchronously with the shared CCLK, eliminating timing skew or external arbitration logic. The AT17LV512-10CI's CEO functionality is validated for use with Xilinx, Altera, and Atmel FPGA families in Master Serial topology.
Can the AT17LV512-10CI be reprogrammed in the field, and what interface is required?
Yes, the AT17LV512-10CI supports in-system programming (ISP) via a two-wire serial interface activated by pulling SER_EN low. During ISP, the device accepts commands and data through the DATA and CLK pins, with A2 (shared with CEO) used for device addressing in multi-device setups. Programming is performed at the same VCC supply voltage - no external high-voltage generator is needed, as internal charge pumps generate required programming voltages. This enables field updates of FPGA configuration without device removal, and the AT17LV512-10CI retains full functionality after 100,000 write cycles.
What package options are available for the AT17LV512-10CI, and why is the 8-lead LAP significant?
The AT17LV512-10CI is offered in the 8-lead Leadless Array Package (LAP), designated 8CN4, measuring 6 mm × 6 mm × 1 mm. This package is pin-compatible with standard 8-lead SOIC footprints, allowing drop-in replacement without PCB redesign. Its leadless construction improves thermal dissipation (θJA = 135.71°C/W) and mechanical robustness in vibration-prone industrial applications. The AT17LV512-10CI's LAP option delivers space savings over PDIP or PLCC alternatives while maintaining compatibility with automated assembly processes.
