Product details
Overview
AT17LV512-10SI from Microchip Technology (formerly Atmel) is a 512-Kbit serial FPGA configuration EEPROM designed to store and load bitstreams for SRAM-based FPGAs in industrial environments. It supports dual-voltage operation (3.3V ±10% or 5.0V ±10%), features programmable reset polarity, offers 100,000 write cycles, and provides 90-year data retention at 85°C. It interfaces directly with Xilinx XC4000/XC5200/Spartan, Altera FLEX/APEX, and Atmel AT40K/AT94K FPGAs.
For engineers reviewing the AT17LV512-10SI datasheet, AT17LV512-10SI pinout, AT17LV512-10SI application, or AT17LV512-10SI equivalent, key selection criteria include industrial temperature support (–40°C to +85°C), cascading capability via CEO output, low-power standby current (100 µA at 3.3V), 20-lead PLCC package compatibility, and ISP via two-wire bus with SER_EN control.
Technical Context
The AT17LV512-10SI operates in Master Serial mode, where the FPGA drives CLK and controls CE/RESET/OE to sequence configuration data from its internal address counter. Its CEO output enables daisy-chained configurations by asserting CE of the next device upon completion of readout.
It implements a CMOS EEPROM process with programmable reset polarity (RESET/OE or RESET/OE), write protection via WP1/WP2 pins (available on this variant), and SER_EN-gated two-wire ISP mode. Standby mode is entered when CE is high, reducing ICCS to 100 µA (industrial, 3.3V).

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; supports only 3.3V; no WP1/WP2; CEO pin present but different timing specs | Higher density for larger FPGAs; lacks dual-voltage flexibility and industrial-grade retention | Select when >512 Kbit is required and system operates exclusively at 3.3V |
| Microchip (Atmel) AT17LV010-10JI | 1-Mbit capacity; identical 20-lead PLCC package; same industrial temp, CEO, SER_EN, and WP1/WP2 support | Drop-in PCB replacement with double memory depth; same pinout and timing behavior | Choose for future-proofing or when FPGA bitstream size exceeds 512 Kbit |

FAQ
What is the maximum clock frequency supported by the AT17LV512-10SI during FPGA configuration?
The AT17LV512-10SI supports up to 15 MHz at 3.3 V in commercial conditions and 10 MHz at 3.3 V under industrial conditions (–40°C to +85°C). At 5.0 V, maximum frequency rises to 15 MHz for both commercial and industrial grades. These values are specified in the AC Characteristics tables and define the upper limit for reliable data transfer timing during FPGA master serial loading.
Does the AT17LV512-10SI support cascading with other AT17LV devices?
Yes, the AT17LV512-10SI supports cascading via its CEO (Chip Enable Output) pin, which goes active low when its internal address counter reaches the final memory location. This signal can directly drive the CE input of the next AT17LV device in a daisy chain, enabling seamless expansion beyond 512 Kbit. The CEO feature is confirmed present and functional for AT17LV512/010/002 variants per datasheet Figures 2-4 and 2-5.
What package type is used for the AT17LV512-10SI, and is it RoHS-compliant?
The AT17LV512-10SI uses a 20-lead PLCC (Plastic Leaded Chip Carrier) package, JEDEC MS-018 compliant, with body dimensions 10.0 mm × 10.0 mm × 3.9 mm. It is RoHS-compliant and halide-free, meeting Pb-free and green packaging requirements as confirmed in Section 22.2 "Green Package Options" of the datasheet.
Can the AT17LV512-10SI be programmed in-system, and what interface is required?
Yes, the AT17LV512-10SI supports in-system programming (ISP) using a two-wire serial interface. Programming is enabled by pulling the SER_EN pin low, after which standard two-wire protocol (clock + bidirectional data) is used. No external high-voltage programming supply is needed - all required voltages are generated internally.
What is the data retention specification for the AT17LV512-10SI at industrial temperature?
The AT17LV512-10SI guarantees 90 years of data retention at 85°C for industrial-grade operation. This value is explicitly stated in the "High-reliability" bullet under Features and confirmed in Section 1, "Description", and applies specifically to the AT17LV512/010/002 family members - not extrapolated from lower-density variants.
