Product details

Overview

AT17F16-30JI from Microchip Technology (formerly Atmel) is a 16-Mbit (16,777,216 × 1-bit) serial configuration PROM designed to store and deliver FPGA bitstreams in Master Serial mode. It operates at 3.3 V ±10%, supports 33 MHz serial download, features 5 V–tolerant I/O pins, and delivers active current ≤40 mA at 3.6 V/33 MHz - enabling reliable boot-time configuration for Xilinx Virtex®, Spartan®, and Altera FLEX® FPGAs.

For engineers reviewing the AT17F16-30JI datasheet, AT17F16-30JI pinout, AT17F16-30JI application, or AT17F16-30JI equivalent, key selection criteria include industrial temperature range (−40°C to +85°C), 8-lead LAP package compatibility with SOIC footprints, cascading CEO-driven daisy-chain support, and ISP capability via 2-wire bus with SER_EN control.

Technical Context

The AT17F16-30JI implements a serial-access flash memory architecture optimized for FPGA configuration sequencing. Its internal logic includes a programmable address counter, tri-state DATA output controlled by CE and RESET/OE, and page-select logic (PAGESEL[1:0] + PAGE_EN) enabling 4-partitioned 4-Mbit memory mapping.

It supports two distinct operational modes: FPGA configuration mode (SER_EN = High), where CLK drives bitstream delivery synchronized to FPGA CCLK, and In-System Programming mode (SER_EN = Low), using a 2-wire interface with A2 as device select and internal charge-pump programming at 3.3 V only.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory size	16,777,216 × 1-bit (16 Mbit); stores full configuration bitstream for mid-to-high-end SRAM-based FPGAs like Xilinx XC5200 or Virtex.
Supply voltage	2.97 V to 3.63 V; compatible with standard 3.3 V system rails and tolerant of ±10% variation without external regulation.
Max clock frequency	33 MHz (SER_EN = High); enables sub-500 ms configuration time for typical 1–2 Mbit FPGA designs.
Operating temperature	−40°C to +85°C; qualified for industrial environments including factory automation and outdoor telecom equipment.
Write endurance	10,000 write cycles; sufficient for field firmware updates, reconfiguration, and prototyping iterations.
Standby current	≤2 mA (industrial grade); minimizes power impact during FPGA idle or sleep states.
I/O voltage tolerance	5 V tolerant on all inputs (CLK, CE, RESET/OE, PAGE_EN, PAGESEL[1:0], SER_EN); simplifies level-shifting in mixed-voltage systems.

Pinout & Package

AT17F16-30JI is packaged in an 8-lead Leadless Array Package (LAP), 6 mm × 6 mm × 1.04 mm body, pin-compatible with 8-lead SOIC/VOIC footprints. The package uses exposed metal pads for thermal conduction and complies with RoHS, Pb-free, and halide-free requirements.

Pin/Terminal	Circuit Role	Design Meaning
DATA (Pin 1)	Three-state bi-directional data I/O	Drives FPGA DIN during configuration; serves as open-collector bidirectional line for 2-wire ISP programming.
CLK (Pin 2)	Configuration clock input	Synchronized to FPGA CCLK; increments internal address/bit counter and controls serial data timing.
RESET/OE (Pin 3)	Active-Low reset / Active-High output enable	Resets address counter and tristates DATA when low; enables DATA output when high and CE is low.
CE (Pin 4)	Active-Low chip enable	Enables read operation and DATA output when low; forces standby mode (≤2 mA) when high during SER_EN = High.
GND (Pin 5)	Ground reference	Requires 0.2 µF decoupling capacitor to VCC for stable power integrity during high-speed serial reads.
CEO (Pin 6)	Chip enable output	Signals end-of-data by going low; used to cascade multiple AT17F devices by driving CE of next device in chain.
SER_EN (Pin 7)	Serial enable input	Must be high for FPGA configuration; pulled up internally (20 kΩ) - tie to VCC if not used for ISP.
VCC (Pin 8)	Power supply	+3.3 V ±10%; powers all logic and flash array; internal regulator supports 2-wire ISP without external HV.

Key Features

Feature	Design Value
In-system programmability (ISP)	Enabled via 2-wire serial interface (SER_EN = Low), eliminating need for socketed programmers and supporting field firmware updates.
Cascadable configuration	CEO output directly drives CE of next AT17F device, enabling seamless daisy-chain expansion beyond 16 Mbit without external logic.
Page-select configuration	PAGE_EN + PAGESEL[1:0] partition memory into four 4-Mbit pages, allowing dynamic reconfiguration of multi-mode FPGA systems (e.g., test vs. production bitstreams).
5 V–tolerant I/O	All digital inputs accept 0–5 V signals, enabling direct interfacing with legacy 5 V controllers or level-flexible FPGA I/O banks.
Low-power standby	Draws ≤2 mA at 3.6 V while CE = High, reducing system-level quiescent power in always-on embedded platforms.

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 XC18V04	4-Mbit capacity; 3.3 V core; no page-select or ISP; requires external 12 V for programming.	Limited to smaller FPGAs; unsuitable for field updates or multi-image storage.	Select when cost-sensitive, single-image, non-upgradable systems require Xilinx-qualified PROMs.
Microchip (Atmel) AT17F08-30JI	8-Mbit capacity; identical pinout, timing, and feature set except memory depth.	Supports smaller FPGAs (e.g., XC3000, AT40K); insufficient for Virtex or Spartan-II+ bitstreams.	Select when design uses <8 Mbit configuration data and footprint reuse with AT17F16-30JI is required.

Compared with XC18V04, AT17F16-30JI offers 4× memory density, integrated ISP, and page-select flexibility; compared with AT17F08-30JI, it doubles capacity while maintaining identical industrial qualification, package, and timing - making it the optimal upgrade path for scaling FPGA complexity.

FAQ

What is the operating temperature range for AT17F16-30JI?

The AT17F16-30JI is rated for industrial operation from −40°C to +85°C. This range is validated per the Absolute Maximum Ratings and Operating Conditions tables in the official datasheet (3392F–CNFG–2/08), and applies to all electrical specifications including 33 MHz clock operation, 2 mA standby current, and 10,000 write cycles. The "I" suffix explicitly denotes industrial qualification.

Does AT17F16-30JI support in-system programming (ISP)?

Yes, AT17F16-30JI supports ISP via its 2-wire serial interface when SER_EN is driven low. During ISP mode, A2 serves as device-select input, and the internal charge pump enables 3.3 V-only programming - no external high-voltage supply is needed. This capability is confirmed in Section 9 ("Programming Mode") and Pin Description Table 5-1 of the datasheet.

Can AT17F16-30JI be used in a daisy-chain configuration with other AT17F devices?

Yes, AT17F16-30JI supports hardware daisy-chaining using its CEO output pin, which drives the CE input of the next device in the chain. This behavior is defined in Section 5.8 (CEO description) and Section 8 ("Cascading Serial Configuration Devices"), and enables seamless expansion beyond 16 Mbit without external logic or FPGA intervention.

What package type does AT17F16-30JI use, and is it compatible with standard SOIC footprints?

AT17F16-30JI uses the 8-lead Leadless Array Package (LAP), 6 mm × 6 mm × 1.04 mm, specified as package code "8CN4". As stated in Section 19 and Figure 20.1 of the datasheet, it is pin-compatible with 8-lead SOIC and VOIC footprints - enabling drop-in replacement in existing layouts without PCB redesign.

Is AT17F16-30JI RoHS compliant and lead-free?

Yes, AT17F16-30JI is RoHS compliant and offered in green (Pb/halide-free) packaging, as confirmed in Section 19 ("Green Package Options") and the ordering information table. The "J" in the part number denotes the 8CN4 LAP package, and the "I" suffix confirms industrial temperature grade - both fully aligned with RoHS Directive 2011/65/EU requirements.
