Product details
Overview
AT17F16-30JU from Microchip Technology (formerly Atmel) is a 16-Mbit in-system programmable serial configuration PROM designed to store FPGA bitstreams for SRAM-based FPGAs including Xilinx Virtex®, Spartan®, and Altera APEX™ devices. It operates at 3.3 V ±10%, supports up to 33 MHz serial download, delivers 5 V–tolerant I/O pins, and features cascading capability via CEO output. Used in industrial FPGA configuration systems requiring reliable nonvolatile boot memory.
For engineers reviewing the AT17F16-30JU datasheet, AT17F16-30JU pinout, AT17F16-30JU application, or AT17F16-30JU equivalent, key selection criteria include 8-lead LAP package compatibility, industrial temperature range (−40°C to +85°C), 10,000 write-cycle endurance, ISP support via 2-wire bus, and FPGA master serial mode timing compliance.
Technical Context
The AT17F16-30JU implements a serial flash memory architecture with internal address counter, tri-state DATA output, and page-select logic enabling four 4-Mbit partitions when PAGE_EN is asserted. Its control interface (CE, RESET/OE, CLK) directly synchronizes with FPGA CCLK and DIN signals without external controller intervention.
It supports dual operational modes: FPGA configuration mode (SER_EN = High) with 33 MHz max clock and daisy-chain CEO-driven CE handoff; and 2-wire ISP mode (SER_EN = Low) using A2 for device selection and SER_EN/CLK/DATA for programming at 3.3 V only. READY pin provides open-collector power-on reset status indication.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 16,777,216 × 1-bit (16 Mbit) - sufficient for full configuration of mid-range Xilinx XC4000 or Altera FLEX 10K FPGAs |
| Supply voltage | 3.3 V ±10% - compatible with standard FPGA I/O banks and eliminates level-shifting in 3.3 V systems |
| Max clock frequency | 33 MHz (SER_EN = High) - enables sub-500 ms configuration time for typical 1–2 Mbit bitstreams |
| Write endurance | 10,000 cycles - supports field firmware updates and reconfiguration during development and maintenance |
| Operating temperature | −40°C to +85°C - qualified for industrial embedded FPGA applications without derating |
| I/O tolerance | 5 V tolerant inputs - allows direct connection to legacy 5 V control logic without external buffers |
| Standby current | ≤2 mA at 3.6 V - minimizes system power budget during FPGA idle or sleep states |
Pinout & Package
AT17F16-30JU 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 |
|---|---|---|
| 1: DATA | Three-state bidirectional data I/O | Drives FPGA DIN during configuration; used as open-collector bi-directional line during 2-wire ISP programming |
| 2: CLK | Configuration clock input | Synchronizes bitstream readout with FPGA CCLK; must meet tLC/tHC ≥15 ns for 33 MHz operation |
| 3: RESET/OE | Active-low reset / active-high output enable | Resets internal address counter on low pulse; enables DATA driver when high and CE low |
| 4: CE | Active-low chip enable | Enables address counter and DATA output when low; forces standby mode when high (ICCS ≤2 mA) |
| 5: GND | Ground reference | Requires 0.2 µF decoupling capacitor to VCC per datasheet layout recommendation |
| 6: CEO (A2) | Chip enable output / ISP device select | In configuration mode: signals end-of-data to next cascaded PROM; in ISP mode: functions as A2 chip-select input |
| 7: SER_EN | Serial enable input | High = FPGA configuration mode; Low = 2-wire ISP mode; tied to VCC for standard use |
| 8: VCC | Power supply | +3.3 V ±10% supply; includes internal 20 kΩ pull-up resistor |
Key Features

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 XC18V02 | 2-Mbit capacity, 3.3 V only, no 5 V–tolerant I/O, no page-select feature | Targeted for smaller Xilinx FPGAs; lacks cascading CEO and ISP capability | Select when bitstream size ≤2 Mbit and system uses only Xilinx FPGAs with no requirement for field reprogramming |
| Microchip (Atmel) AT17F002-30JU | 2-Mbit version in identical 8-lead LAP package, same industrial temp range and ISP support | Lower density; suitable for AT40K or early XC3000 FPGAs with smaller configuration files | Choose for cost-sensitive designs where 2 Mbit suffices and footprint compatibility with AT17F16-30JU is required for scalability |

FAQ
What is the operating temperature range for AT17F16-30JU?
The AT17F16-30JU is rated for industrial operation from −40°C to +85°C. This specification is confirmed in the Absolute Maximum Ratings and Operating Conditions sections of the official datasheet (3392F–CNFG–2/08). The device maintains full functionality-including 33 MHz serial download, 10,000 write cycles, and proper CEO timing-across this full range without derating. Its 8-lead LAP package supports thermal dissipation consistent with industrial board-level requirements.
Does AT17F16-30JU support in-system programming (ISP)?
Yes, AT17F16-30JU supports in-system programming via a 2-wire serial interface when SER_EN is driven low. In this mode, the device uses DATA and CLK as bidirectional lines, with A2 (CEO pin) serving as device-select input. Programming occurs at 3.3 V only, with internal charge pumps generating required programming voltages. The AT17F Programming Specification (available on Microchip's website) defines protocol details, and compatibility is confirmed with Atmel's ATDH2200E system and third-party programmers.
What FPGA families is AT17F16-30JU explicitly compatible with?
AT17F16-30JU is explicitly listed as compatible with Atmel AT40K/AT94K, Altera FLEX®/APEX™, Lucent ORCA®, Xilinx XC3000/XC4000/XC5200/Spartan®/Virtex®, and Motorola MPA1000 FPGAs. This compatibility is documented in the Features section and validated through timing alignment with Master Serial mode requirements-including CEO handoff, RESET/OE synchronization, and CCLK-driven clocking. No additional glue logic is required for these supported families.
Can AT17F16-30JU be used in a daisy-chain configuration?
Yes, AT17F16-30JU supports daisy-chain configuration via its CEO (Chip Enable Output) pin. When the internal address counter reaches its maximum value (or selected page boundary), CEO goes low and enables the CE input of the next AT17F16-30JU in the chain. This behavior is specified in the Pin Description and Cascading Serial Configuration Devices sections. Up to four devices can be cascaded to support larger bitstreams, with automatic handoff timing verified in AC Characteristics Table 16.1.
What is the purpose of the PAGE_EN and PAGESEL pins on AT17F16-30JU?
PAGE_EN and PAGESEL[1:0] enable 4-page memory partitioning in AT17F16-30JU. When PAGE_EN is high, the 16-Mbit address space is divided into four 4-Mbit pages (00000h–3FFFFh, 40000h–7FFFFh, etc.), selected by PAGESEL[1:0]. This allows storing and selecting distinct FPGA bitstreams for runtime reconfiguration. These pins are inactive when SER_EN is low (ISP mode) and have defined internal pull-down/pull-up resistors per Pin Description section.
