Product details

Overview

AT17F080-30JU from Microchip Technology (formerly Atmel) is an 8-Mbit FPGA configuration PROM designed for serial master-mode loading of SRAM-based FPGAs. It delivers 8,388,608 × 1-bit storage, supports up to 33 MHz serial download clock, operates at 3.3 V ±10%, features 5.0 V-tolerant I/O pins, and is packaged in a 20-lead PLCC for industrial temperature range (−40°C to +85°C).

For engineers reviewing the AT17F080-30JU datasheet, AT17F080-30JU pinout, AT17F080-30JU application, or AT17F080-30JU equivalent, this device serves as a nonvolatile, in-system programmable configuration memory for Xilinx Virtex®, Spartan®, Altera FLEX®/APEX™, and Lucent ORCA® FPGAs - with cascading support, page-select capability, and ISP via 2-wire bus.

Technical Context

The AT17F080-30JU implements a serial flash-based architecture optimized for FPGA bitstream delivery in Master Serial mode. Its control logic synchronizes with FPGA CCLK, uses CE and RESET/OE to manage address counter reset and DATA output enable, and supports daisy-chained configurations via CEO-to-CE interconnection.

It integrates dual operational modes: SER_EN = High enables standard FPGA configuration readout with 33 MHz max clock; SER_EN = Low activates 2-wire ISP programming using internal charge-pump voltage generation. Page-select logic (PAGE_EN + PAGESEL[1:0]) partitions the 8-Mbit address space into four 2-Mbit pages for multi-bitstream reconfiguration.

FAQ

What is the primary function of the AT17F080-30JU in an FPGA-based system?

The AT17F080-30JU functions as a serial configuration PROM that stores and delivers FPGA bitstreams during power-up or reconfiguration. It interfaces directly with SRAM-based FPGAs (e.g., Xilinx Virtex®, Altera APEX™) in Master Serial mode, using CLK, DATA, CE, and RESET/OE signals. Its 8-Mbit capacity supports complex FPGA designs, and its PLCC package enables socketed deployment for prototyping and field updates. AT17F080-30JU eliminates the need for external controllers during configuration.

Does the AT17F080-30JU support in-system programming (ISP), and how is it enabled?

Yes, the AT17F080-30JU supports ISP via a 2-wire serial interface. ISP is activated by driving the SER_EN pin low, which places the device into programming mode and repurposes A2 as a chip-select input. Programming occurs at 3.3 V only, with internal charge-pump circuitry generating required voltages - no external high-voltage supply is needed. Standard industry programmers (e.g., ATDH2200E, ATDH2225) and third-party tools support this mode. AT17F080-30JU retains full configuration functionality when SER_EN is high.

How does the page-select feature of the AT17F080-30JU improve system flexibility?

The AT17F080-30JU divides its 8-Mbit memory into four 2-Mbit pages using PAGE_EN and PAGESEL[1:0] inputs. When PAGE_EN is high, users can select any page to load independently - enabling runtime switching between different FPGA configurations (e.g., test vs. production, sensor A vs. sensor B). This eliminates the need to reprogram the entire device for minor updates. AT17F080-30JU maintains full backward compatibility with flat-address operation when PAGE_EN is held low.

Can the AT17F080-30JU be used in daisy-chain configurations, and what pin enables this?

Yes, the AT17F080-30JU supports daisy-chaining via its CEO (Chip Enable Output) pin. After completing its own bitstream delivery, CEO goes low and automatically enables the CE input of the next AT17F080-30JU (or compatible device) in the chain. This enables seamless cascaded configuration of multiple FPGAs or expansion beyond 8 Mbit. The CEO pin is electrically compatible with CE inputs across the AT17F family, and AT17F080-30JU's timing specifications guarantee reliable handoff under 33 MHz operation.

What are the key electrical differences between the AT17F080-30JU and the AT17F080-30CU?

The AT17F080-30JU and AT17F080-30CU share identical memory density (8 Mbit), timing (33 MHz max clock), voltage (3.3 V ±10%), I/O tolerance (5 V), and functional features (page select, ISP, cascading). Their sole difference is packaging: AT17F080-30JU uses a 20-lead PLCC for socketed or through-hole assembly, while AT17F080-30CU uses an 8-pad LAP for compact surface-mount layouts. Both are RoHS-compliant with Sn finish and rated for −40°C to +85°C. AT17F080-30JU is selected when mechanical robustness or legacy footprint compatibility is required.
