EPC16UI88T - 16Mb Enhanced Config Device, 88-pin UBGA | Altera
MPN: EPC16UI88T ✗ انتهى عمره الإنتاجيEPC16UI88T نظرة عامة
An enhanced configuration device (EPC) is a non-volatile flash memory with an Altera-specific serial configuration interface that loads bitstream data into a companion FPGA at power-up, after reconfiguration requests, or via remote in-system programming (ISP). Compared with older EPCS / EPCQ devices, the EPC16 family supports multi-boot, dual-image storage, page-mode decompression and the Altera Passive Parallel (PP) or Passive Serial (AS) configuration schemes, providing a more flexible boot source for Stratix, Cyclone, Arria and other LUT-based Altera devices.
Key features of the EPC16UI88T include 16 Mb of usable configuration memory, parallel data compression to fit larger bitstreams into the same flash density, support for multiple FPGA configuration schemes (PS, AS, FPP), and in-system programmability through the JTAG or Active Serial interface. The device supports a standard 4-wire serial interface plus optional parallel data path, and offers dedicated MSEL[2:0] and nCONFIG/nSTATUS control pins for handshaking with the target FPGA.
Typical applications include boot configuration for mid-density Altera FPGAs (Cyclone III, Cyclone IV, Stratix II GX and similar generation devices), industrial control and factory automation platforms that require remote firmware upgrade capability, networking line cards and base stations, and test/measurement equipment where multi-image storage enables field-safe rollback. The wide operating temperature range and industrial qualification also suit industrial, military, and aerospace ground systems.
When designing with this device, confirm that the target FPGA configuration scheme matches the EPC16 control pin mapping, and observe the 0.8 mm BGA PCB layout rules (laser-drilled vias, microvia stack-ups are recommended for high-density BGA fan-out). Always use the manufacturer-supported Quartus II / Quartus Prime programmer for device programming and verify JTAG chain integrity before ISP operations.

التطبيقات النموذجية
EPC16UI88T مناسب لـ 6 التطبيقs: Altera Cyclone FPGA Boot Configuration, Stratix II GX Multi-Image Boot Storage, Industrial PLC and Factory Automation Controllers, Test & Measurement Instrumentation, Telecommunications Line Cards, Aerospace Ground Systems and Avionics Spares.
Altera Cyclone FPGA Boot Configuration
The EPC16UI88T stores the configuration bitstream for Altera Cyclone III, Cyclone IV and similar mid-density SRAM-based FPGAs at power-up, providing 16 Mbit of non-volatile storage with multi-boot and parallel data compression to fit larger bitstreams. It connects to the FPGA via the Passive Serial, Active Serial, or Fast Passive Parallel interface, allowing remote in-system programming through JTAG or Active Serial. Designers use this configuration memory in industrial controllers and embedded vision platforms where the 0.8 mm UBGA footprint is already established on the PCB.

Stratix II GX Multi-Image Boot Storage
The EPC16UI88T's dual-image multi-boot feature makes it ideal for Stratix II GX-based designs that require a golden image and a field-upgradable image. The 16 Mbit density and parallel data compression allow storage of large Stratix II GX bitstreams with decompression on the fly. Engineers configure the FPGA to fall back to the second image if the first fails CRC verification, supporting field-safe firmware updates in networking line cards and base-station hardware.
موصى به
Industrial PLC and Factory Automation Controllers
The EPC16UI88T serves as the configuration store for industrial PLC platforms built on Altera Cyclone or Arria FPGAs, where remote firmware upgrades over JTAG/Active Serial and long-term -40 C to +85 C operation are mandatory. Its multi-boot capability lets factory engineers roll back to a known-good image after a failed field update, reducing truck rolls. The 88-ball UBGA package supports compact, vibration-resistant industrial board layouts when reinforced with underfill.
موصى به
Test & Measurement Instrumentation
Test and measurement instruments benefit from the EPC16UI88T's ability to store multiple FPGA configuration images for different test personalities (e.g., oscilloscope, logic analyzer, BERT) on the same hardware. The 16 Mbit capacity accommodates large Arria II/Arria V bitstreams used in high-speed ADC interfacing. Fast Passive Parallel mode supports faster configuration times, reducing instrument boot latency and improving production-line throughput.
موصى به
Telecommunications Line Cards
In telecom line cards built on Altera Stratix II / Stratix IV FPGAs, the EPC16UI88T provides reliable non-volatile configuration storage with in-system programming through the JTAG chain shared with the FPGA. Multi-boot support is critical for telecom equipment requiring field-safe firmware rollouts and carrier-grade reliability. The 88-ball UBGA package and 3.3V operation suit standard telecom board power rails and assembly processes.
موصى به
Aerospace Ground Systems and Avionics Spares
The EPC16UI88T is used in aerospace ground equipment and avionics spares where legacy Altera FPGA designs must continue operating beyond the original part's active lifecycle. The industrial -40 C to +85 C temperature range, multi-boot image fallback, and stable long-term flash retention make it suitable for mission-critical support hardware. Engineers typically qualify multiple sources (EPC16UI88, EPC16UI88N) for obsolescence management per DO-254/DO-160 guidelines.

ملاحظات التصميم
Estimated: the EPC16UI88T's 88-ball UBGA package uses a 0.8 mm pitch; design microvia-in-pad or laser-drilled stacked vias on all BGA pads, and route all signals on inner layers to escape the dense ball array. Use a 4- or 6-layer PCB stack-up with dedicated ground and power planes beneath the device. Avoid routing high-speed signals (DCLK, DATA[15:0]) across plane splits to prevent reference plane discontinuities that degrade signal integrity during Fast Passive Parallel configuration.
Provide a clean 3.3 V rail to the EPC16UI88T with at least a 1 uF decoupling capacitor placed within 5 mm of the VCC pins, plus a 0.1 uF high-frequency bypass cap adjacent to the device. During in-system programming through JTAG, peak current can spike to 30-50 mA per VCC pin; insufficient decoupling may cause programming failures or bit corruption. Use a low-impedance power plane rather than traces to minimize voltage droop during ISP operations.
Do not confuse the EPC16UI88T (enhanced configuration device, 16 Mbit, 88-ball UBGA) with the EPCQ16 or EPCS16 (Quad-Serial / Serial Configuration Devices). They use different configuration protocols and pin mappings; substituting one for the other requires FPGA MSEL pin reconfiguration and board rework. When migrating from EPC16 to EPCQ, confirm the target FPGA supports the new configuration scheme and verify the JTAG chain still includes both devices correctly.
Keep the DCLK trace between the EPC16UI88T and the target FPGA under 50 mm (estimated) and series-terminate at the source if length exceeds 25 mm. Match the length of DATA[15:0] in FPP mode within +/-2 mm to avoid setup/hold violations during configuration. Place the 25 MHz or 40 MHz configuration clock oscillator close to the EPC16UI88T's CLK pin to minimize jitter, and route it on an inner stripline layer with continuous ground reference.
