EPC16QI100TBAC 概要

The Altera EPC16QI100TBAC is a 16-Mbit in-system programmable Enhanced Configuration Device designed as a single-chip, high-speed configuration solution for high-density SRAM-based FPGAs. Built on a flash-memory architecture divided into a configuration controller and a flash array, it delivers stored configuration bitstreams through the Altera Passive Parallel Synchronous (PPS) and Passive Parallel Asynchronous (PPA) configuration modes, supporting all modern Altera FPGA families including Stratix, Cyclone, and Arria series devices.

What is an Enhanced Configuration Device? An Enhanced Configuration Device (EPC) is a non-volatile flash-memory companion IC that stores FPGA configuration bitstreams and delivers them to the target FPGA at power-up or under host control. It replaces older discrete EPROM + micro-controller boot-prom designs with a single chip that integrates the configuration controller, flash array, and interface logic, reducing BOM count and simplifying multi-FPGA system bring-up.

Key features of the EPC16QI100TBAC include 16 Mbits (2 Mbytes) of storage, support for up to eight configuration pages selectable via PGM[2..0] pins, dynamic in-system reconfiguration, 3.3V single-supply operation, and a 100-pin PQFP package. The page-mode feature allows designers to store up to eight distinct FPGA images and switch between them at runtime, enabling field upgrades, A/B redundancy, and multi-persona hardware platforms.

The architecture separates configuration control logic from the flash array, allowing data compression (up to 15-30% density gain depending on FPGA family) and built-in error detection. The IC supports JTAG (IEEE 1149.1) boundary-scan and programming, plus a 4-pin passive serial interface option. Configuration clock rates up to 40 MHz in synchronous mode minimize FPGA wake-up time for fast-boot applications.

Typical applications include Altera/Intel Stratix, Cyclone, and Arria FPGA boot memory, telecom line cards requiring remote firmware upgrades, industrial controllers with multi-image fallback, broadcast video processing platforms, and military/aerospace systems requiring multi-persona reconfigurable hardware. The wide-pitch 100-pin PQFP package is suitable for production through-hole soldering and is often chosen for legacy or high-reliability assemblies where BGA is undesirable.

When designing with the EPC16QI100TBAC, ensure the 3.3V supply rail is decoupled with 0.1 µF and 10 µF capacitors placed within 5 mm of the power pins, and follow Altera's configuration waveform timing diagrams for nSTATUS, nCONFIG, and CONF_DONE handshaking. For multi-page designs, allocate PGM[2..0] to GPIO outputs on a host MCU or CPLD to allow runtime page selection. The IC is rated for the industrial temperature range and is lead-free.

🖥️

Altera/Intel Cyclone Series FPGA Boot Memory

The EPC16QI100TBAC is the canonical boot-PROM companion for Altera Cyclone III and Cyclone IV FPGAs, providing 16 Mbit (2 Mbyte) of non-volatile configuration storage. With 3.3V single-supply operation, it connects directly to the Cyclone MSEL[2..0]-configured Passive Parallel Synchronous (PPS) interface and streams configuration data at up to 40 MHz DCLK, achieving <100 ms wake-up times for fast-boot industrial control applications. The 16 Mbit capacity comfortably fits Cyclone III EP3C40/EP3C80 and Cyclone IV EP4CE40/EP4CE55 bitstreams even with compression disabled. Designers should strap MSEL pins for AS or PPS mode and follow Altera's configuration waveform timing diagrams for nSTATUS/nCONFIG/CONF_DONE handshaking.

🌐

Telecom Line Card with Remote Firmware Upgrade

Telecommunications line cards built on Altera Stratix III/IV or Arria GX FPGAs use the EPC16QI100TBAC to support remote field upgrades. The on-chip 8-page memory architecture (selectable via PGM[2..0]) allows an A/B redundancy scheme: one page holds the current production image, a second holds a staged upgrade, and a third holds a known-good golden image for fallback if a remote upgrade is interrupted. A host CPU writes the new image to a spare page over JTAG or SPI, asserts the PGM bits to switch, and triggers nCONFIG to reload. The 100-pin PQFP package withstands the -40C to +85C industrial temperature range required by ETSI EN 300 019 telecom ambient specifications.

🏭

Industrial Multi-Persona Reconfigurable Hardware

Programmable Logic Controllers (PLCs) and industrial test platforms that need to host multiple FPGA personalities on a single board leverage the EPC16QI100TBAC's 8-page capability to switch between operation modes in the field. Up to eight distinct FPGA bitstreams - for example, a motor-control image, a vision-processing image, and a communications-protocol image - can be stored simultaneously and selected via three GPIO pins driven by a host MCU. Compared with smaller 1-Mbit or 4-Mbit EPC parts, the EPC16QI100TBAC's 16 Mbit capacity accommodates the largest persona without compression. The 100-pin PQFP's through-hole-friendly lead pitch supports hand-soldered rework on legacy industrial boards where BGA is not acceptable.

📺

Broadcast Video Processing Platforms

Broadcast video routers and SDI/HDMI processing cards built on Altera Arria GX FPGAs require reliable configuration memory that can hold multi-format firmware. The EPC16QI100TBAC stores up to 16 Mbit of configuration data, sufficient for Arria GX EP1AGX20/EP1AGX35 bitstreams including soft-core CPU subsystems. Its in-system programmability via JTAG (IEEE 1149.1) means broadcast OEMs can apply field updates without removing cards from the chassis. The dynamic page-mode reconfiguration also enables runtime switching between HD and UHD processing pipelines in the same hardware, a common requirement in modern broadcast infrastructure.

✈️

Military/Aerospace Multi-Mission Reconfigurable Systems

Defense and aerospace platforms such as unmanned aerial vehicle (UAV) avionics and electronic-warfare subsystems use the EPC16QI100TBAC to support multi-mission reconfigurability. Up to eight mission-specific FPGA images (ISR, EW, communications) can be stored in the 16 Mbit flash array and selected by mission profile via PGM[2..0], enabling a single hardware platform to be re-tasked in the field without physical swap. The -40C to +85C industrial temperature range meets MIL-STD-810 environmental requirements for many deployed platforms. The wide-pitch PQFP-100 package is also preferred for high-shock/vibration environments where fine-pitch BGA solder joints are a reliability concern.

🔧

Test & Measurement Instrumentation with Multi-FPGA Setup

Automated Test Equipment (ATE) and bench-top instruments built around multiple Altera FPGAs use the EPC16QI100TBAC as a single-chip multi-FPGA configuration store. Because the EPC can cascade configuration data to multiple FPGAs in daisy-chain mode, one EPC16QI100TBAC can boot a chain of two or three FPGAs, eliminating the need for per-FPGA boot PROMs and reducing BOM cost. The 16 Mbit density supports the largest test-instrument firmware images, and the JTAG interface allows production-line programming and post-assembly verification. The 100-pin PQFP is well suited to bench-instrument PCBs that prioritize reworkability over board density.

💊

Medical Imaging Device FPGA Configuration

Medical imaging systems such as ultrasound carts, CT scanners, and digital X-ray detectors built on Altera Stratix or Arria FPGAs use the EPC16QI100TBAC for reliable regulatory-compliant boot storage. The 16 Mbit capacity holds the full imaging-pipeline bitstream including soft-core CPU firmware, DSP blocks, and image-processing IP. The in-system JTAG programmability allows OEMs to apply FDA-tracked field updates without disassembling the device. The -40C to +85C industrial temperature range suits the elevated ambient temperatures inside sealed imaging enclosures. Altera's long-life-cycle support of legacy FPGAs in medical grade programs makes the EPC16QI100TBAC a stable choice for IEC 60601-1 compliant designs.

What is the EPC16QI100TBAC used for?
The EPC16QI100TBAC is a 16-Mbit in-system programmable Enhanced Configuration Device that stores and delivers FPGA configuration bitstreams at power-up. According to the Altera datasheet, it targets Altera Stratix, Cyclone, and Arria SRAM-based FPGAs and supports up to eight configuration pages selectable via the PGM[2..0] pins, enabling multi-image and remote-field-upgrade architectures.
Where can I buy EPC16QI100TBAC?
As of 2026-09-11, EPC16QI100TBAC inventory is constrained because the part is on Altera's last-time-buy roadmap. Authorized distributors such as DigiKey, Mouser, and Avnet may show limited stock, while brokers like Jotrin and FPGAkey may list factory-traceable inventory at premium pricing. Always request a Certificate of Conformance (CoC) when sourcing from non-franchised channels.
What is the price of EPC16QI100TBAC?
As of 2026-09-11, single-piece pricing for EPC16QI100TBAC is approximately USD 28.50, with quantity breaks at USD 25.20 (10 pcs), USD 21.75 (100 pcs), USD 18.40 (500 pcs), and USD 15.95 (1,000 pcs). Last-time-buy allocation and shrinking supply typically push unit prices upward over the product lifecycle, so design-in orders should be placed ahead of the LTB cutoff date.
What is the lead time for EPC16QI100TBAC?
Lead time for EPC16QI100TBAC is currently variable because Altera has placed the part on last-time-buy status. As of 2026-09-11, franchised distributors quote 8-12 weeks for factory orders, while broker inventory is usually available for immediate shipment. Contact your Altera/Intel FPGA field representative to confirm the LTB deadline before placing a volume order.
Is EPC16QI100TBAC in stock?
Stock for EPC16QI100TBAC is limited and varies by distributor as of 2026-09-11. Jotrin, DigiPart, and FPGAkey list the part, but quantities are typically sub-100-piece lots reflecting last-time-buy channel inventory. For production runs, place a non-cancellable, non-returnable purchase order with Altera/Intel before the LTB window closes.
EPC16QI100TBAC vs EPC16QI100N - what is the difference?
EPC16QI100TBAC and EPC16QI100N are both 16-Mbit Enhanced Configuration Devices in the 100-pin PQFP package. The TBAC suffix denotes an industrial-temperature, lead-free tape-and-reel variant, whereas EPC16QI100N is typically a commercial-temperature, tube-packaged variant. Both share the same die and pinout, so TBAC can drop in for the N version in industrial designs.
EPC16QI100TBAC vs EPC16QC100 - which is better for Stratix II designs?
The EPC16QC100 targets older Altera APEX and Stratix/Stratix II FPGAs using 1.8V configuration signaling, while the EPC16QI100TBAC targets newer Cyclone and Arria devices using 3.3V signaling. For Stratix II designs, the EPC16QC100 remains the recommended match. The EPC16QI100TBAC is the correct choice for Cyclone III/IV and Arria GX systems.
When should I choose EPC16QI100TBAC over EPC64QI100?
Choose EPC16QI100TBAC (16 Mbit) over the smaller EPC64QI100 (64 Mbit - note naming: the '64' denotes 64 Mbit in this family) only when your target FPGA configuration bitstream fits in 16 Mbit. Cyclone III designs typically fit comfortably in 16 Mbit; larger Stratix IV/V or Arria 10 designs require 64 Mbit or larger EPC devices, so pick the EPC64QI100 in those cases.
What is the best drop-in replacement for EPC16QI100TBAC?
The best drop-in replacements for EPC16QI100TBAC are other Altera Enhanced Configuration Devices in the 100-pin PQFP package, such as EPC16QI100N (commercial temp) and EPC16QC100 (for older 1.8V FPGAs). The EPC16QI100TBAC is pin-compatible with the EPC16QI100 family, so any EPC16QI100x variant in the same 100-pin PQFP can be substituted subject to temperature grade verification.
Where to download EPC16QI100TBAC datasheet PDF?
The EPC16QI100TBAC datasheet PDF is available from the Altera/Intel FPGA documentation library and mirror sites such as Alldatasheet and PDF datasheet live. The base datasheet (document covers the EPC16QI100 family; the TBAC variant is a packaging/temperature option of the same die) provides configuration waveforms, JTAG programming instructions, and pin assignments.
What is the pinout of EPC16QI100TBAC?
The EPC16QI100TBAC pinout is the standard Altera 100-pin PQFP Enhanced Configuration Device pinout shared with EPC16QI100, EPC16QI100N, EPC16QC100, and EPC16QC100N. Key pins include DATA[15..0], DCLK, nCS, nSTATUS, nCONFIG, CONF_DONE, PGM[2..0], JTAG (TCK/TMS/TDI/TDO), and supply/ground. Refer to the Altera datasheet for the full pin map.
Can EPC16QC100T replace EPC16QI100TBAC?
Yes, the EPC16QC100T can functionally replace EPC16QI100TBAC only in designs that match the 1.8V I/O signaling of the EPC16QC100 family. For 3.3V Altera FPGA families (Cyclone III/IV, Arria GX), the EPC16QC100T is not a drop-in replacement because of the supply-voltage difference. Confirm your target FPGA's configuration-bank voltage before swapping.
What are the key specifications of EPC16QI100TBAC that engineers should know?
Engineers should know that the EPC16QI100TBAC stores 16 Mbit (2 Mbyte) of FPGA configuration data in 3.3V flash, supports up to 8 configuration pages via PGM[2..0] pins, runs the PPS/PPA configuration modes at up to 40 MHz, comes in a 100-pin PQFP (20x14 mm) package rated -40C to +85C, is in-system programmable via JTAG (IEEE 1149.1), and supports dynamic in-system reconfiguration. It is on Altera's last-time-buy roadmap, so design-in should be planned with the LTB deadline in mind.
What is the best cross-brand equivalent for EPC16QI100TBAC?
There is no direct cross-brand drop-in equivalent for EPC16QI100TBAC because the Altera EPC family uses a proprietary configuration interface optimized for Altera/Intel FPGAs. Xilinx FPGAs use the Platform Flash XCF family, and Lattice uses its own iCE/iCE40 boot-PROMs. For a multi-FPGA Altera design, the EPC16QI100TBAC remains the canonical choice; cross-brand migration requires switching to a different FPGA vendor.

選定ガイド

Choose EPC16QI100TBAC when you need an industrial-temperature, lead-free, 16 Mbit boot-PROM for Altera/Intel Cyclone III/IV or Arria GX FPGAs in a 100-pin PQFP package. Choose EPC16QI100N for commercial-temperature prototypes (0C to +70C) at lower cost. Choose EPC16QI100T for industrial temperature with tape-and-reel packaging suited to high-volume SMT assembly. Choose EPC16QC100 / EPC16QC100N / EPC16QC100T for older Altera Stratix-II and APEX20KE FPGAs that require 1.8V configuration signaling. For designs needing more than 16 Mbit (e.g. Stratix IV/V), select the larger EPC64QI100 or EPC128QI100. Cross-brand migration is not possible because each FPGA vendor uses proprietary configuration-PROM interfaces.

設計ノート

Decouple the EPC16QI100TBAC 3.3V supply with a 0.1 µF X7R ceramic capacitor placed within 5 mm of each VCC pin, plus a bulk 10 µF tantalum or ceramic capacitor near the package. The configuration device draws brief peak currents during read bursts; insufficient decoupling can corrupt configuration data and cause FPGA configuration failures that are difficult to debug. Place the decoupling on the same layer as the device with vias direct to the ground plane.

Route the 16-bit DATA[15..0] bus to the target FPGA in a controlled-impedance topology with matched lengths within +/- 200 mils to preserve signal integrity at the 40 MHz maximum DCLK rate. Keep DCLK and nCONFIG traces short and isolated from switching-power lines. Place the EPC16QI100TBAC within 50 mm of the target FPGA to minimize transmission-line effects, and provide a solid ground reference plane directly under the DATA bus.

MSEL pin strapping on the target FPGA must match the configuration mode (PPS or PPA) selected on the EPC16QI100TBAC. A common design error is leaving MSEL floating or tying it to the wrong voltage, which causes the FPGA to attempt AS or JTAG configuration and fail to handshake with the EPC. Always consult Altera's configuration handbook for the target FPGA's MSEL pin configuration table, and tie MSEL pins to VCC or GND via 1 kohm resistors rather than direct straps for easy rework.

The nSTATUS, nCONFIG, and CONF_DONE open-drain handshaking signals require external 4.7 kohm pull-ups to VCC. Failing to provide adequate pull-up strength causes intermittent configuration failures on long or noisy boards. The JTAG chain TCK/TMS/TDI/TDO signals should also be pulled to known states at board reset to prevent spurious JTAG state transitions that can leave the EPC in an undefined configuration mode.

Although the PQFP-100 package has a moderate theta_JA of approximately 50 C/W, the EPC16QI100TBAC's flash read/write operations generate brief power bursts. For industrial applications operating at the +85C upper temperature limit, ensure at least 1 square inch of unbroken copper pour is provided on both top and bottom PCB layers connected to the GND pins. Forced airflow is not required at typical configuration-clock rates but is recommended for sustained JTAG programming during production.
