Product details
Overview
AT17LV010-10PI from Atmel is a 1-Mbit (1,048,576 × 1-bit) serial EEPROM FPGA configuration memory supporting both 3.3V and 5.0V operation, featuring in-system programmability via two-wire bus, programmable reset polarity, and cascading capability via CEO output for multi-FPGA systems. It targets industrial-grade FPGA configuration in SRAM-based logic designs.
For engineers reviewing the AT17LV010-10PI datasheet, AT17LV010-10PI pinout, AT17LV010-10PI application, or AT17LV010-10PI equivalent, key selection criteria include industrial temperature range (−40°C to +85°C), 8-lead PDIP package compatibility, CEO-enabled daisy-chain support, low-power standby current (≤100 µA at 3.3V), and verified interoperability with Xilinx XC4000/Virtex and Altera FLEX/APEX families.
Technical Context
The AT17LV010-10PI implements a serial master-mode configuration interface synchronized to FPGA CCLK, using CE, RESET/OE, and SER_EN to control address counter enablement, output tri-state behavior, and ISP mode entry. Its CEO output enables hardware-cascaded read-back across multiple devices without external logic.
It supports dual-voltage operation (3.3V ±10% or 5.0V ±5%/±10%), features programmable reset polarity stored in EEPROM, and includes write-protection inputs (WP1, WP2) active only during programming - not during FPGA loading. The device uses internal charge-pump circuitry for programming at standard VCC.
Key Specifications

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 XC18V01 | 1-Mbit serial PROM; supports only 3.3V operation; no CEO output; no WP1/WP2; different pinout (SOIC-8) | Lacks cascading capability and dual-voltage support - unsuitable for mixed-voltage or multi-FPGA systems | Select only if system is strictly 3.3V and uses single FPGA with SOIC-8 footprint |
| Microchip (Atmel) AT17LV002-10JI | 2-Mbit capacity; identical pinout, voltage, temperature, and feature set - direct upgrade path | Provides double configuration storage for larger FPGAs or dual-bitstream redundancy | Choose when future FPGA upgrades require >1 Mbit or fault-tolerant dual-image storage |
Compared with XC18V01, AT17LV010-10PI offers industrial temperature support, CEO-based daisy chaining, and 3.3V/5.0V flexibility - enabling broader system integration. Versus AT17LV002-10JI, it delivers optimal cost/performance for 1-Mbit FPGA configurations without over-provisioning memory.

FAQ
What is the maximum clock frequency supported by AT17LV010-10PI during FPGA configuration?
The AT17LV010-10PI supports up to 15 MHz at 3.3V under commercial conditions and 10 MHz at 3.3V under industrial conditions. At 5.0V, it operates up to 15 MHz commercially and 12.5 MHz industrially. These values are specified in the AC Characteristics tables and reflect guaranteed timing margins for reliable bitstream delivery to Xilinx and Altera FPGAs.
Does AT17LV010-10PI support cascading with other AT17LV devices, and how is it implemented?
Yes, AT17LV010-10PI supports hardware cascading via its CEO (Chip Enable Output) pin. When the device reaches its final address, CEO asserts low and enables the CE input of the next AT17LV device in the chain. This daisy-chain mechanism requires no FPGA logic or external control - making it ideal for multi-FPGA systems like telecom line cards or modular I/O controllers.
Can AT17LV010-10PI be programmed in-system, and what interface is required?
Yes, AT17LV010-10PI supports in-system programming (ISP) via a two-wire serial interface. Programming is enabled by pulling SER_EN low, then using CLK and DATA lines with standard I²C-like protocol. No high-voltage programming supply is needed - all voltages are generated internally from VCC, allowing field updates without removing the device from the PCB.
What is the purpose of the RESET/OE pin on AT17LV010-10PI, and is its polarity configurable?
The RESET/OE pin on AT17LV010-10PI serves dual functions: active-Low reset and active-High output enable. Its logic polarity is fully programmable in EEPROM - allowing users to configure it as either RESET/OE or RESET/OE to match specific FPGA boot requirements. This eliminates hardware redesign when migrating between FPGA families with differing reset conventions.
Which FPGA families are explicitly compatible with AT17LV010-10PI according to the official documentation?
AT17LV010-10PI is explicitly documented as compatible with Atmel AT6000/AT40K/AT94K, Altera FLEX/APEX, Lattice ORCA, and Xilinx XC3000/XC4000/XC5200/Spartan/Virtex families. Compatibility is based on verified Master Serial mode timing, pin mapping, and configuration sequence - not generic SPI or serial PROM emulation.
