Product details
Overview
AT17LV010-10JI from Microchip Technology (formerly Atmel) is a 1-Mbit serial EEPROM FPGA configuration memory, supporting both 3.3V and 5.0V operation, with in-system programmability via two-wire bus, programmable reset polarity, and cascading capability via CEO output. It targets industrial-grade FPGA configuration in SRAM-based systems including Xilinx XC4000/XC5200 and Altera FLEX/APEX platforms.
For engineers reviewing the AT17LV010-10JI datasheet, AT17LV010-10JI pinout, AT17LV010-10JI application, or AT17LV010-10JI equivalent, key selection criteria include industrial temperature range (−40°C to +85°C), 20-lead PLCC package compatibility, CEO-driven daisy-chain support, low-power standby current (100 µA at 3.3V), and verified interoperability with Xilinx Virtex and Altera APEX FPGAs.
Technical Context
The AT17LV010-10JI implements a serial master-configuration interface for SRAM-based FPGAs, using CLK-synchronized DATA output with tri-state control via RESET/OE and CE. Its internal address counter auto-resets on power-up and supports cascaded read-back through CEO assertion when the final bit is transmitted.
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 responds to FPGA-generated CCLK and CE signals; in ISP mode, it accepts serial programming commands while generating internal high-voltage programming pulses without external super-voltage supplies.

FAQ
What is the operating voltage range supported by the AT17LV010-10JI?
The AT17LV010-10JI supports dual-voltage operation: 3.0–3.6 V (±10%) and 4.5–5.5 V (±10% for industrial grade). This allows direct use in both 3.3V and 5V system designs without level-shifting circuitry, and the device automatically adapts its internal logic thresholds based on applied VCC.
Does the AT17LV010-10JI support daisy-chaining with other configuration memories?
Yes, the AT17LV010-10JI supports daisy-chaining via its CEO (Chip Enable Output) pin. When the internal address counter reaches its maximum value, CEO asserts low to enable the CE input of the next AT17LV-series device in the chain. This feature is confirmed for AT17LV010-10JI in the official datasheet and enables scalable configuration for multi-FPGA systems.
What package type is used for the AT17LV010-10JI, and is it pin-compatible with other AT17LV variants?
The AT17LV010-10JI uses a 20-lead PLCC (Plastic Leaded Chip Carrier) package per ordering code "JI". It shares identical pinout and functionality with AT17LV512-10JI and AT17LV002-10JI, but is not pin-compatible with the 8-lead LAP/SOIC/PDIP variants (e.g., AT17LV010-10PC) due to differing pin counts and signal assignments.
Can the AT17LV010-10JI be programmed in-system, and what interface is required?
Yes, the AT17LV010-10JI supports in-system programming (ISP) via a two-wire serial interface activated by pulling SER_EN low. Programming occurs at standard VCC levels (no external high-voltage supply needed), and industry-standard algorithms handle reset polarity configuration and block protection using WP1 and WP2 inputs.
What is the data retention specification for the AT17LV010-10JI under industrial conditions?
The AT17LV010-10JI guarantees 90 years of data retention at 85°C ambient temperature, as specified in the official datasheet for industrial-grade parts. This is validated under accelerated testing and reflects real-world performance in thermally demanding applications such as base station equipment and industrial control cabinets.
