EPC16UI88 Visão geral
A configuration PROM is a non-volatile memory device that retains the FPGA bitstream when system power is removed. At power-on reset, the FPGA enters configuration mode and clocks data out of the PROM through a serial configuration chain (typically Altera's Passive Serial, Passive Parallel Synchronous, or Passive Parallel Asynchronous modes). The EPC16 family supports multi-device configuration chains, allowing one PROM to configure multiple FPGAs, or stacking several PROMs to configure larger devices. Compared with loading bitstreams from external flash, EPC16 devices reduce board space, lower BOM cost, and provide Altera-validated timing guarantees for configuration clock rates up to 100 MHz.
Key specifications include 16 Mb of configuration memory (2 Mbytes), 3.3V core supply, JTAG/IEEE 1149.1 in-system programmability, support for multi-device cascading, and an operating temperature range suitable for industrial applications. The 88-ball UBGA package provides fine-pitch interconnect with thermal characteristics appropriate for embedded industrial and communication systems where the PROM is mounted near the FPGA it configures. The device's low standby current and rapid configuration clock support fast system wake-up times.
The EPC16UI88 supports several Altera configuration modes: Passive Serial (PS), Passive Parallel Synchronous (PPS), Passive Parallel Asynchronous (PPA), and JTAG. Configuration is initiated by the FPGA's nCONFIG pin, after which the PROM presents bitstream data on DATA[7:0] (parallel) or DATA0 (serial) under control of DCLK. Designers must ensure that the EPC16UI88's density and package match the target FPGA's configuration requirements before final placement.
Typical applications include Altera Cyclone II/III, Cyclone IV, Stratix II, and Stratix III FPGA-based embedded boards in industrial automation, communications infrastructure, and test-and-measurement systems. The PROM enables remote field upgrades through JTAG, simplifying firmware revision management in deployed equipment.
When designing with the EPC16UI88, follow Altera's recommended decoupling scheme (0.1 uF and 10 uF capacitors close to VCC pins) and route JTAG signals as a four-wire bus (TCK, TMS, TDI, TDO) with proper termination. Ensure that the configuration clock frequency is within the FPGA's supported range, and verify multi-device cascade timing when chaining multiple FPGAs.

Aplicações típicas
EPC16UI88 é adequado para 6 aplicaçãos: Altera Cyclone III FPGA Configuration, Altera Stratix II FPGA Configuration, Industrial Automation Control Boards, Communications Infrastructure (Baseband / DSP Boards), Test and Measurement Instrumentation, Military / Aerospace Single-Board Computers.
Altera Cyclone III FPGA Configuration
The EPC16UI88 stores the 16 Mb configuration bitstream that boots Altera Cyclone III FPGAs at system power-on. The PROM streams the bitstream to the FPGA through the Passive Serial (PS) or Passive Parallel Synchronous (PPS) interface, governed by the Cyclone III nCONFIG/nSTATUS handshake. With up to 100 MHz DCLK, the EPC16UI88 loads mid-density Cyclone III bitstreams in tens of milliseconds, enabling rapid FPGA wake-up. The 88-ball UBGA package mounts directly beneath or adjacent to the Cyclone III on the same PCB. Compared with loading bitstreams from external parallel flash, the EPC16UI88 reduces BOM cost, simplifies board layout, and provides Altera-validated timing. The JTAG interface also enables field firmware updates via ByteBlasterMV or USB-Blaster cables.
Recomendado
Altera Stratix II FPGA Configuration
The EPC16UI88 supports configuration of mid-density Altera Stratix II FPGAs that require 16 Mb of bitstream storage. Stratix II devices use the Passive Parallel Asynchronous (PPA) mode supported by the EPC16UI88, which streams data on DATA[7:0] controlled by DCLK and the FPGA's nCONFIG signal. The PROM's 3.3V supply and 88-ball UBGA package suit high-density telecom and DSP boards. With cascading support via nCE/nCEO, multiple Stratix II FPGAs can be configured sequentially from one PROM chain. Per Altera configuration documentation, designers must verify that the target Stratix II device's bitstream fits within 16 Mb before final placement, and must follow the reference schematic for DCLK trace length matching.
Recomendado
Industrial Automation Control Boards
Industrial automation controllers using Altera Cyclone II or Cyclone IV FPGAs rely on the EPC16UI88 for reliable field-deployed boot storage. The PROM's industrial operating temperature range (-40C to +85C) and in-system JTAG programmability simplify factory firmware provisioning and remote firmware updates via JTAG without removing the board from service. Industrial PLC and motion-control boards benefit from the compact 88-ball UBGA package, which fits within the dense control board layout alongside motor driver and analog front-end circuits. The PROM's 3.3V supply aligns with industrial 24V-to-3.3V power architectures. For new industrial designs, Altera recommends migrating to EPCQ16 serial flash with Cyclone V/10, but the EPC16UI88 remains in production for legacy platforms.
Recomendado
Communications Infrastructure (Baseband / DSP Boards)
Telecommunications baseband and DSP boards often use Altera Stratix II/III or Cyclone III FPGAs that require parallel configuration PROMs. The EPC16UI88 streams the configuration bitstream at up to 100 MHz DCLK, minimizing baseband-card boot latency - critical in hot-swap, line-card-insertion, and redundant-ring failover scenarios. The 88-ball UBGA package allows tight placement near the FPGA to keep DCLK and DATA[7:0] traces short, reducing EMI susceptibility. The PROM's low standby current supports cold-spare line cards where quiescent power is constrained. Multi-device cascade support enables one PROM chain to load multiple FPGAs on the same baseband card, reducing total BOM cost.
Recomendado
Test and Measurement Instrumentation
Test-and-measurement instruments such as oscilloscopes, logic analyzers, and protocol analyzers use mid-density Altera FPGAs that the EPC16UI88 configures at power-up. The PROM's JTAG in-system programmability allows instrument manufacturers to ship products with one firmware and field-update them for new measurement standards or compliance updates - critical for long-lifecycle test equipment deployed in validation labs. The 88-ball UBGA package supports dense multi-FPGA instruments where several FPGAs collaborate on DSP and data-acquisition tasks. Combined with nCE/nCEO cascading, the EPC16UI88 simplifies configuration management across multi-FPGA instruments while preserving the precise timing the FPGA needs at boot.
Recomendado
Military / Aerospace Single-Board Computers
Legacy military and aerospace single-board computers use Altera Cyclone, Stratix II, and APEX II FPGAs that the EPC16UI88 configures. The industrial temperature range and ruggedized board designs in this segment require stable boot PROMs that retain bitstreams for many years without bit-rot. The EPC16UI88's JTAG field-upgrade capability supports mission updates for deployed systems. The 88-ball UBGA is compatible with high-vibration, conformal-coated board assemblies. For new aerospace designs, Altera recommends newer EPCQ flash on supported FPGAs, but the EPC16UI88 continues to support legacy platforms with field-proven reliability and Altera documentation covering configuration timing, JTAG chain order, and cascade topology.

Notas de projeto
Decouple VCC pins on the EPC16UI88 with 0.1 uF ceramic and 10 uF bulk capacitors placed within 5 mm of the BGA balls, per Altera reference schematics. The 3.3V supply should be derived from the same low-noise rail that powers the target FPGA's VCCINT/VCCAUX to avoid ground-bounce-induced configuration errors. Bulk capacitors must supply the inrush current during DCLK-driven configuration without violating VCC droop tolerances.
Route DCLK and DATA[7:0] traces as a tightly matched bus with length-matched within 50 mils to avoid configuration timing violations. Per Altera configuration documentation, trace impedance should be controlled to 50 ohms single-ended. Place the EPC16UI88 within 50 mm of the target FPGA to minimize trace-induced jitter on DCLK at 100 MHz operation.
Do not use the EPC16UI88 with newer Altera FPGAs such as Cyclone V/10, Arria, or Stratix V/10 - those use EPCQ serial flash, not EPC16 parallel PROMs. Verify the target FPGA's configuration controller in its datasheet before selecting the EPC16UI88. The 16 Mb capacity also must exceed the FPGA bitstream size; otherwise, configure bitstream compression or migrate to a denser PROM.
