Product details

Overview

AT17F080A-30QC 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 33 MHz serial download speed, features 5.0V-tolerant I/O pins, operates at 3.3V ±10%, and is qualified for industrial temperature range (–40°C to +85°C). It enables single-device multi-bitstream reconfiguration in systems using Altera Stratix/Cyclone or Atmel AT40K/AT94K FPGAs.

For engineers reviewing the AT17F080A-30QC datasheet, AT17F080A-30QC pinout, AT17F080A-30QC application, or AT17F080A-30QC equivalent, key selection criteria include cascading capability via nCASC, page-selectable memory partitioning (PAGE_EN/PAGESEL), ISP programming via 2-wire bus, standby current ≤3 mA, and compatibility with FPGA master serial configuration protocols.

Technical Context

The AT17F080A-30QC implements a dedicated serial configuration interface with DCLK output and DATA bidirectional open-collector I/O, enabling direct connection to FPGA DIN/DCLK pins without external logic. Its internal address counter auto-resets on power-up and RESET/OE assertion, and it supports four-page memory partitioning when PAGE_EN is high.

It integrates low-power CMOS FLASH technology with 100,000 write cycles endurance and embeds on-chip voltage generation for 3.3V-only programming-no external VPP required. The device enters low-power standby (<3 mA) when nCS is high and SER_EN is high, and supports daisy-chain cascading via nCASC-to-nCS interconnection across multiple devices.

Pinout & Package

AT17F080A-30QC is packaged in a 20-lead Plastic J-Leaded Chip Carrier (PLCC), designated as package code "J" per Atmel ordering nomenclature. This JEDEC MS-018 AA-compliant package measures 9.78 mm × 9.78 mm × 3.81 mm and features gull-wing leads with 1.27 mm pitch.

Pin/Terminal	Circuit Role	Design Meaning
DCLK	Three-state clock output	Drives FPGA DCLK input; outputs clock during configuration, functions as input only during ISP mode (SER_EN = Low).
DATA	Open-collector bi-directional I/O	Drives FPGA DIN during configuration; used for 2-wire ISP programming; requires external pull-up for proper logic levels.
nCS	Active-low chip select input	Enables address counter and DATA driver when low; forces standby mode when high (with SER_EN = High); ignored during ISP.
RESET/OE	Combined reset and output enable	Active-low reset clears address/bit counters; active-high OE enables DATA output driver when nCS is low.
nCASC	Cascade select output	Goes low when internal address counter reaches max value; used to chain multiple AT17FxxxA devices in daisy-chain configuration.
PAGE_EN	Page enable input	When high, partitions 8-Mbit address space into four 2-Mbit pages; enables selective bitstream loading without full reprogramming.
PAGESEL[1:0]	Page select inputs	Binary-encoded address bits selecting one of four 2-Mbit pages (00–11); inactive when PAGE_EN = Low.
SER_EN	Serial enable input	Must be high for FPGA configuration; pulled high internally; driven low to enter 2-wire ISP programming mode.
READY	Open-collector reset indicator	Driven low during power-on reset; released (high-impedance) when internal initialization completes; requires external 4.7 kΩ pull-up.
VCC / GND	Power supply and ground	VCC = 3.3V ±10%; 0.2 μF decoupling capacitor recommended between VCC and GND for noise immunity.

Key Features

Feature	Design Value
Page-selectable memory architecture	Four independent 2-Mbit pages selectable via PAGE_EN and PAGESEL[1:0], enabling rapid system reconfiguration by loading alternate bitstreams without erasing entire memory.
In-system programmability (ISP)	2-wire serial programming interface (SER_EN low) allows field updates using ATDH2225 cable or third-party programmers-no socket removal required.
FPGA master serial mode compliance	Direct pin-to-pin interface with Altera Cyclone/Stratix and Atmel AT40K/AT94K FPGAs; no external controller needed for automatic power-up configuration.
Cascadable configuration chain	nCASC output drives nCS of next device in chain, supporting multi-FPGA systems or configurations exceeding 8 Mbit capacity with seamless handoff timing.
5.0V-tolerant I/O with 3.3V core	Allows interoperability with mixed-voltage systems-e.g., 5V FPGA mode pins or microcontroller GPIOs-without level translators or voltage dividers.

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 XC18V08PC44C	8-Mbit serial PROM; 3.3V operation; no page-select or cascading nCASC output; requires external 12V VPP for programming.	Limited to Xilinx FPGA ecosystems; lacks built-in page partitioning and daisy-chain signaling; higher programming complexity.	Choose when targeting Xilinx-only designs and legacy toolchains; avoid if multi-FPGA or field-upgrade capability is required.
Microchip (Atmel) AT17F080A-30JU	Identical electrical and functional specification; same 20-lead PLCC package but with green (lead-free/halogen-free) finish instead of standard Sn finish.	No functional difference; differs only in RoHS compliance status and surface finish-no impact on thermal, mechanical, or electrical performance.	Select AT17F080A-30JU for new designs requiring full RoHS compliance; AT17F080A-30QC remains valid for legacy Sn-finish assembly lines.

Compared with XC18V08PC44C, AT17F080A-30QC offers integrated page selection and cascading, reducing system-level logic and enabling flexible bitstream management; versus AT17F080A-30JU, it provides identical functionality with conventional Sn lead finish-ideal for backward-compatible manufacturing transitions.

FAQ

What is the primary function of the AT17F080A-30QC in an FPGA-based system?

The AT17F080A-30QC serves as a dedicated serial configuration PROM that stores and delivers FPGA bitstreams during power-up or reconfiguration events. It interfaces directly with the FPGA's master serial pins (DIN, DCLK), eliminating the need for external controllers. Its 8-Mbit capacity supports complex SRAM-based FPGAs such as Altera Cyclone IV or Atmel AT94KAL, and its built-in page-select logic enables multi-bitstream storage for system flexibility.

Does the AT17F080A-30QC support in-system programming (ISP), and how is it implemented?

Yes, the AT17F080A-30QC supports in-system programming via a 2-wire serial interface activated when SER_EN is driven low. Programming occurs at 3.3V only-no external high-voltage supply is needed-as internal circuitry generates required programming voltages. Compatible tools include the Atmel ATDH2225 ISP cable and third-party programmers listed in the AT17FxxxA Programming Specification. This enables field updates without removing the device from the PCB.

How does the PAGE_EN and PAGESEL[1:0] functionality work in the AT17F080A-30QC?

When PAGE_EN is high, the AT17F080A-30QC divides its 8-Mbit address space into four 2-Mbit pages. PAGESEL[1:0] selects which page is active during serial download-00 selects 00000h–1FFFFh, 01 selects 20000h–3FFFFh, etc. When PAGE_EN is low, the full 8-Mbit space (00000h–7FFFFh) is used contiguously. This allows a single AT17F080A-30QC to store and rapidly switch between up to four distinct FPGA configurations without reprogramming.

Can multiple AT17F080A-30QC devices be connected in a daisy-chain configuration, and what is required?

Yes, AT17F080A-30QC devices support daisy-chain cascading using the nCASC output and nCS input. When the first device reaches its final address, nCASC goes low, enabling the nCS input of the next device in the chain. This allows sequential loading of larger bitstreams across multiple FPGAs or expansion beyond 8 Mbit. Each device must have SER_EN tied high, and nCASC of device N connects to nCS of device N+1; RESET/OE should be shared for synchronized reset.

What are the key timing parameters that affect FPGA configuration speed using the AT17F080A-30QC?

The AT17F080A-30QC supports up to 33 MHz serial clock (DCLK) frequency, enabling fast configuration loads. Critical AC parameters include TCAC (DCLK to DATA delay ≤30 ns), TOE (OE to DATA delay ≤55 ns), and TLC/THC (DCLK low/high time ≥15 ns each). These ensure setup/hold timing margins are met for FPGA DIN sampling. For reliable operation, FPGA DCLK input must meet these timing windows-verified in the AC Characteristics table of the Atmel-2823E datasheet.
