Product details
Overview
AT17F080-30CI from Atmel is an 8-Mbit in-system programmable serial configuration PROM designed to store FPGA bitstreams for SRAM-based FPGAs including Xilinx Virtex®, Spartan®, XC4000™, and Altera FLEX® devices. It supports master serial mode configuration, operates at 3.3V ±10%, features 5V-tolerant I/O pins, and delivers up to 33 MHz serial download speed. Its primary role is nonvolatile configuration memory in industrial-grade FPGA systems.
For engineers reviewing the AT17F080-30CI datasheet, AT17F080-30CI pinout, AT17F080-30CI application, or AT17F080-30CI equivalent, key selection criteria include industrial temperature range (–40°C to +85°C), cascading capability via CEO/CE daisy-chain, page-selectable memory partitioning, ISP support via 2-wire bus, and compatibility with legacy AT24CXXX EEPROM interfaces.
Technical Context
The AT17F080-30CI implements a serial flash architecture with internal address counter, tri-state DATA output controlled by RESET/OE and CE, and configurable 4-page memory partitioning via PAGESEL[1:0] and PAGE_EN. Its CEO output enables daisy-chained configuration of multiple FPGAs or larger bitstreams.
It operates in two distinct modes: FPGA configuration mode (SER_EN = High) with 33 MHz max CLK frequency, and 2-wire ISP programming mode (SER_EN = Low) supporting VCC-only programming without external high-voltage sources. The device integrates internal pull-up (20 kΩ on DATA, RESET/OE, SER_EN) and pull-down (30 kΩ on PAGE_EN, PAGESEL[1:0]) resistors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Capacity | 8,388,608 × 1-bit (8 Mbit) - stores full configuration bitstream for high-end SRAM FPGAs like Xilinx Virtex or Altera APEX. |
| Supply Voltage | 3.3 V ±10% - compatible with modern FPGA I/O banks; supports industrial operation from –40°C to +85°C. |
| Max Serial Clock Frequency | 33 MHz - enables fast FPGA configuration startup time; reduces system boot latency. |
| Endurance | 5,000 write cycles - sufficient for development, field updates, and reconfiguration in embedded systems. |
| I/O Tolerance | 5V tolerant inputs - allows direct interfacing with 5V logic or legacy controllers without level shifters. |
| Standby Current | <1 mA - minimizes power consumption during FPGA idle or sleep states. |
| Page Partitioning | 4 configurable pages (00–11) - enables storage and selective loading of multiple FPGA configurations (e.g., firmware variants, test modes). |
Pinout & Package
AT17F080-30CI is available in 8-lead Leadless Array Package (LAP), 6 mm × 6 mm × 1 mm, pin-compatible with 8-lead SOIC/VOIC. This compact surface-mount package supports high-density PCB layouts and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| DATA | Bi-directional open-collector I/O | Serial data path for configuration bitstream output to FPGA DIN; also used as bidirectional line during 2-wire ISP programming. |
| CLK | Input | Drives internal address/bit counter; synchronized to FPGA CCLK; determines configuration timing and maximum 33 MHz download rate. |
| RESET/OE | Input/Output control | Active-Low reset of address counter; active-High output enable for DATA; dual-function pin critical for FPGA handshake and recovery. |
| CE | Input | Chip Enable (active Low); controls DATA driver and counter enable; used for daisy-chaining via CEO-to-CE connection between devices. |
| GND | Power reference | Ground return for all logic and memory circuits; requires 0.2 µF decoupling capacitor near VCC pin. |
| CEO (A2) | Output / Input | Chip Enable Output (active Low when end-of-data reached); also functions as A2 device select during ISP programming (SER_EN = Low). |
| SER_EN | Input | Serial Enable (High = configuration mode; Low = 2-wire ISP mode); must be tied to VCC for normal FPGA boot operation. |
| VCC | Power supply | +3.3 V ±10% supply input; powers internal flash array, logic, and I/O buffers; supports industrial temperature range. |
Key Features
| Feature | Design Value |
|---|---|
| In-System Programmability (ISP) | Enables field firmware updates via 2-wire serial interface without removing device; eliminates need for socketed programming. |
| Cascadable CEO/CE daisy-chain | Allows chaining multiple AT17F080-30CI units to configure multi-FPGA systems or extend total bitstream capacity beyond 8 Mbit. |
| 4-page memory partitioning | Supports independent storage and dynamic selection of up to four FPGA configurations using PAGESEL[1:0] and PAGE_EN, enabling runtime reconfiguration. |
| 5V-tolerant I/O pins | Permits direct connection to 5V microcontrollers, CPLDs, or legacy host systems without external level-shifting circuitry. |
| Emulation of AT24CXXX EEPROMs | Provides drop-in replacement capability for existing AT24C01–AT24C512 designs, simplifying migration to higher-density configuration memory. |

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 XC18V08 | 8-Mbit serial PROM; same 3.3V operation and 33 MHz max clock; lacks PAGE_EN/PAGESEL paging logic and 2-wire ISP mode. | Designed exclusively for Xilinx FPGAs; no Altera or Lucent ORCA® compatibility; no emulation of AT24CXXX protocols. | Select XC18V08 only for pure-Xilinx ecosystems where paging and cross-vendor compatibility are unnecessary. |
| Microchip (Atmel) AT17LV080 | Same 8-Mbit density and LAP/PLCC/TQFP packages; operates at 2.7–3.6 V; identical pinout and ISP capability; rated for commercial temp only (0°C to +70°C). | Not qualified for industrial temperature range; unsuitable for deployments requiring –40°C operation or extended thermal cycling. | Choose AT17LV080 only for cost-sensitive commercial applications where industrial qualification is not required. |
Compared with XC18V08 and AT17LV080, the AT17F080-30CI uniquely combines industrial temperature rating, 4-page memory partitioning, 2-wire ISP, and multi-vendor FPGA compatibility-including explicit support for Altera FLEX®, Xilinx Virtex®, and Lucent ORCA®-making it the only option meeting full legacy system upgrade and field-reprogrammability requirements.

FAQ
What is the operating temperature range for AT17F080-30CI?
The AT17F080-30CI is rated for industrial operation from –40°C to +85°C. This specification is guaranteed per its ordering code suffix "I" and validated in the Absolute Maximum Ratings and Operating Conditions tables of the official datasheet (Rev. 3039G–CNFG). It ensures reliable configuration memory performance in demanding environments such as factory floors or outdoor embedded systems.
Does AT17F080-30CI support daisy-chaining with other configuration PROMs?
Yes, AT17F080-30CI supports daisy-chaining via its CEO (Chip Enable Output) pin, which drives low upon reaching the end of its memory address space. In a cascade, CEO of one AT17F080-30CI connects to CE of the next device, enabling automatic handoff during FPGA configuration. This is explicitly documented in the Cascading Serial Configuration Devices section of the datasheet.
Can AT17F080-30CI replace AT17F040 in an existing design?
Yes - AT17F080-30CI is pin-compatible with AT17F040 in all shared packages (8-lead LAP, 20-lead PLCC), offering double the memory (8 Mbit vs. 4 Mbit) without layout changes. Its identical electrical interface, timing, and command set ensure drop-in functionality, provided the FPGA design accommodates the extended address space.
What programming tools are compatible with AT17F080-30CI?
AT17F080-30CI supports programming via Atmel's ATDH2200E Programming Kit and ATDH2225 ISP Cable, as well as industry-standard third-party programmers that implement the Atmel 2-wire serial programming protocol. The device does not require external high-voltage supplies - all programming voltages are generated internally at 3.3 V.
How does the PAGE_EN and PAGESEL feature work in AT17F080-30CI?
When PAGE_EN is driven high, AT17F080-30CI partitions its 8-Mbit address space into four 2-Mbit pages. PAGESEL[1:0] selects which page is active during serial download (e.g., PAGESEL=00 accesses 00000h–1FFFFh). This enables storage and on-demand retrieval of multiple FPGA configurations - a capability confirmed in Table 2 and the PAGESEL[1:0] pin description of the datasheet.
