Product details
Overview
AT17F080A-30QI from Microchip Technology (formerly Atmel) is an 8-Mbit FPGA configuration PROM designed for serial master-mode loading of SRAM-based FPGAs including Altera Stratix/Cyclone/APEX and Atmel AT40K/AT94K devices. It delivers 3.3V output capability, 5.0V-tolerant I/O pins, fast 33MHz serial download speed, and supports in-system programming via 2-wire bus. It operates across -40°C to +85°C industrial temperature range.
For engineers reviewing the AT17F080A-30QI datasheet, AT17F080A-30QI pinout, AT17F080A-30QI application, or AT17F080A-30QI equivalent, key selection criteria include cascading support via nCASC, four-page memory partitioning (PAGE_EN/PAGESEL), low-power standby current (<3mA), ISP compatibility with ATDH2225 cable, and dual-package availability (8-pad LAP / 20-lead PLCC).
Technical Context
The AT17F080A-30QI implements a serial flash memory architecture optimized for FPGA configuration boot sequences. Its control logic directly interfaces with FPGA DCLK, DIN, and mode pins without external controllers, using RESET/OE and nCS to manage address counter enablement and DATA output tri-state behavior during power-up and cascade handoff.
It supports two operational modes: FPGA configuration mode (SER_EN = High), where DCLK is output-driven and DATA is three-state open-collector, and 2-wire ISP programming mode (SER_EN = Low), enabling in-circuit reprogramming at 3.3V with internal charge-pump voltage generation. PAGE_EN and PAGESEL[1:0] configure 2MB/page partitioning for multi-bitstream storage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 8,388,608 × 1-bit (8 Mbit) nonvolatile flash storage for full FPGA bitstream retention |
| Supply Voltage | 3.3V ±10% (2.97–3.63V); enables direct interface with 3.3V FPGA I/O banks |
| Operating Temperature | -40°C to +85°C industrial grade; validated for embedded control and communications equipment |
| Serial Clock Frequency | Up to 33MHz download speed; reduces FPGA configuration time versus slower PROMs |
| Write Endurance | 100,000 program/erase cycles; supports field firmware updates and design iteration |
| Standby Current | <3mA at 3.3V when nCS = High and SER_EN = High; minimizes system power during idle |

Pinout & Package
AT17F080A-30QI is available in 20-lead PLCC (package code J) - designated as 20J per Microchip documentation. Pin functions are electrically identical across package variants; this section reflects the 20-lead PLCC configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| DCLK | Configuration clock output | Drives FPGA DCLK input; outputs synchronized clock during configuration; input during ISP mode |
| DATA | Bi-directional open-collector data line | Drives FPGA DIN during config; used for 2-wire ISP data; requires external pull-up |
| nCS | Chip select input (active low) | Enables address counter and DATA driver when low; forces standby when high (SER_EN = high) |
| RESET/OE | Reset input / output enable | Active-low reset clears address/bit counters; active-high enables DATA output when nCS is low |
| nCASC | Cascade select output | Goes low when internal counter reaches max address; triggers next device in daisy-chain |
| PAGE_EN | Page enable input | Activates 4-page memory partitioning (2MB/page); must be low for linear 8MB addressing |
| PAGESEL[1:0] | Page select inputs | Binary-select one of four 2MB pages when PAGE_EN = high; no effect otherwise |
| SER_EN | Serial enable input | High = FPGA config mode; Low = 2-wire ISP programming mode; internal pull-up provided |
| READY | Power-on reset indicator | Open-collector output driven low during POR; released after reset completion (requires 4.7kΩ pull-up) |
| VCC / GND | Power supply / reference | 3.3V supply with recommended 0.2μF decoupling capacitor between VCC and GND |
Key Features
| Feature | Design Value |
|---|---|
| Four-page memory partitioning | Enables storage and selective retrieval of up to four independent FPGA bitstreams using PAGE_EN and PAGESEL[1:0] |
| Cascadable nCASC output | Automatically chains multiple AT17F080A-30QI devices by asserting nCASC low at end-of-data to enable next device's nCS |
| In-system programmability (ISP) | Supports field reprogramming via 2-wire serial interface using ATDH2225 cable-no socket removal required |
| 5.0V-tolerant I/O | Accepts 5V logic inputs while powered from 3.3V, simplifying integration with legacy 5V peripherals or level-shifting circuits |
| Low-power standby mode | Draws <3mA when nCS = high and SER_EN = high-critical for battery-backed or energy-sensitive systems |

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 density, 3.3V operation, but lacks PAGE_EN/PAGESEL page-select feature and nCASC cascade signaling | Designed specifically for Xilinx FPGAs; limited third-party FPGA compatibility compared to AT17F080A-30QI | Choose XC18V08 only for Xilinx-only designs where page partitioning and cross-vendor cascade are unnecessary |
| Microchip (Atmel) AT17F080A-30JU | Identical electrical and functional specification; differs only in lead finish (Sn, lead-free/halogen-free) and packaging marking (JU vs QI) | No functional difference; both rated for -40°C to +85°C industrial operation | AT17F080A-30JU is a drop-in replacement with identical pinout and timing-select based on RoHS compliance requirements and distributor stock |
Compared with XC18V08, AT17F080A-30QI offers broader FPGA vendor support and hardware page management; versus AT17F080A-30JU, it shares full functionality but carries a different industrial-grade marking suffix indicating qualified sourcing and traceability for OEM production.

FAQ
What is the maximum serial clock frequency supported by AT17F080A-30QI during FPGA configuration?
The AT17F080A-30QI supports a maximum serial clock frequency of 33MHz during FPGA configuration operations. This value is specified under "Fast Serial Download Speeds up to 33MHz" in the official datasheet and enables rapid bitstream loading to reduce system boot time. The AT17F080A-30QI maintains timing compliance at this rate across its full industrial temperature range (-40°C to +85°C) with appropriate PCB layout and termination.
Does AT17F080A-30QI support in-system programming (ISP), and what interface is required?
Yes, AT17F080A-30QI supports in-system programming via a 2-wire serial interface activated by pulling SER_EN low. Programming is performed at 3.3V with internal charge-pump circuitry generating required programming voltages-no external high-voltage supply needed. Compatible tools include the Atmel ATDH2225 ISP cable and third-party programmers supporting the AT17FxxxA protocol. The AT17F080A-30QI retains full ISP capability regardless of package variant.
How does the PAGE_EN and PAGESEL[1:0] feature work in AT17F080A-30QI?
When PAGE_EN is driven high, the 8-Mbit address space of AT17F080A-30QI is divided into four 2-Mbit pages. PAGESEL[1:0] selects which page is active during serial configuration download-00 selects 00000h–1FFFFh, 01 selects 20000h–3FFFFh, etc. If PAGE_EN remains low, the device operates in linear 8-Mbit mode (00000h–7FFFFh). This feature allows a single AT17F080A-30QI to store and selectively load up to four distinct FPGA configurations.
Can AT17F080A-30QI be used in a daisy-chain configuration with other configuration PROMs?
Yes, AT17F080A-30QI supports hardware daisy-chaining via its nCASC output and nCS input. When the internal address counter reaches its maximum value (or selected page boundary), nCASC goes low, enabling the nCS input of the next AT17F080A-30QI (or compatible device) in the chain. This allows seamless expansion beyond 8 Mbit without external logic-verified in the datasheet's Cascading Serial Configuration Devices section.
What is the purpose of the READY pin on AT17F080A-30QI, and how should it be used?
The READY pin on AT17F080A-30QI is an open-collector output driven low during power-on reset and released (high-impedance) upon completion. It provides hardware confirmation that internal logic initialization is complete and the device is ready to accept configuration commands. A 4.7kΩ pull-up resistor is recommended. System designers use READY to synchronize FPGA startup or delay host controller access until AT17F080A-30QI is fully operational.
