Product details
Overview
AT17LV512-10JI from Microchip Technology (formerly Atmel) is a 512-Kbit serial FPGA configuration EEPROM designed for reliable, in-system programmable storage of SRAM-based FPGA bitstreams. It supports dual-voltage operation (3.3V/5.0V), features cascading CEO output, programmable reset polarity, and operates across -40°C to +85°C industrial temperature range. Used in Xilinx XC4000/XC5200 and Altera FLEX/APEX FPGA systems.
For engineers reviewing the AT17LV512-10JI datasheet, AT17LV512-10JI pinout, AT17LV512-10JI application, or AT17LV512-10JI equivalent, key selection criteria include industrial-grade reliability (90-year data retention at 85°C), 20-lead PLCC package compatibility, cascaded daisy-chain support, low-power standby current (100 µA at 3.3V), and verified interoperability with master serial FPGA configuration protocols.
Technical Context
The AT17LV512-10JI implements a serial EEPROM architecture optimized for FPGA configuration loading via master serial interface, using CLK-driven address incrementing and tri-state DATA output synchronized to CE and RESET/OE control logic. Its CEO output enables automatic handoff between cascaded devices during multi-FPGA or high-density bitstream loading.
It supports two distinct operational modes: FPGA configuration mode (SER_EN = High) and two-wire ISP programming mode (SER_EN = Low), with separate WP1/WP2 write-protection inputs active only during programming. Reset polarity is user-programmable to match FPGA requirements (RESET active-Low/OE active-High default).

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; 3.3V-only; no CEO output; requires external sequencing for cascading | Higher density but lacks native daisy-chain capability; not drop-in for multi-device AT17LV512-10JI chains | Select when single-device 2-Mbit storage suffices and cascading is unnecessary |
| Microchip AT17LV010-10JI | 1-Mbit capacity; identical 20-lead PLCC package; same CEO, SER_EN, and WP1/WP2 pinout | Direct upgrade path for higher-density FPGA configurations without PCB change | Choose when future FPGA bitstream growth exceeds 512 Kbit but PLCC footprint must be retained |

FAQ
What is the maximum clock frequency supported by the AT17LV512-10JI during FPGA configuration?
The AT17LV512-10JI supports a maximum clock frequency of 15 MHz at 3.3V (commercial) and 10 MHz at 3.3V (industrial), and 15 MHz at 5V (commercial/industrial). These values are specified in the AC Characteristics tables and define the upper limit for reliable synchronous bitstream transfer to compatible FPGAs such as Xilinx XC4000/XC5200 and Altera FLEX devices. Exceeding these frequencies may cause data corruption or incomplete configuration.
Does the AT17LV512-10JI support in-system programming (ISP), and what interface is required?
Yes, the AT17LV512-10JI supports in-system programming via a two-wire serial bus activated when SER_EN is driven Low. This mode uses dedicated WP1 and WP2 inputs for block-level write protection and requires an industry-standard programmer (e.g., Atmel ATDH2225 ISP Cable) or compatible tool. During normal FPGA configuration (SER_EN = High), the two-wire interface is disabled and only master-serial signals (CLK, DATA, CE, RESET/OE) are active.
Can the AT17LV512-10JI be used in a daisy-chain configuration with other AT17LV devices?
Yes, the AT17LV512-10JI supports daisy-chaining via its CEO (Chip Enable Output) pin, which asserts Low upon reaching the final memory address. This signal directly drives the CE input of the next AT17LV device in the chain, enabling automatic handoff without external logic. The AT17LV512-10JI is fully compatible with AT17LV128/256/010 devices in cascaded configurations, though AT17LV65 lacks CEO and cannot participate.
What is the data retention specification for the AT17LV512-10JI under industrial operating conditions?
The AT17LV512-10JI guarantees 90 years of data retention at 85°C (industrial temperature grade), as confirmed in the High-reliability section of the datasheet. This applies to the EEPROM memory array after programming and is validated under accelerated life testing. Retention is measured with VCC applied and RESET/OE held inactive; no periodic refresh is required.
Is the AT17LV512-10JI pin-compatible with other packages in the AT17LV family, such as the 8-lead LAP or SOIC variants?
No, the AT17LV512-10JI in 20-lead PLCC is not pin-compatible with 8-lead packages (LAP, PDIP, SOIC) used by AT17LV65/128/256. Per Table 1-1 and Figure 2-4 notes, the 20-lead PLCC pinout is specific to AT17LV512/010/002 devices and includes CEO, WP1, and WP2 pins absent in smaller variants. Migration to 8-lead packages would require PCB redesign and loss of cascading functionality.
