EP1K100QI208-3 - 100K Gates ACEX 1K FPGA, 208-PQFP | Altera
MPN: EP1K100QI208-3 ✗ پایان تولیدEP1K100QI208-3 نمای کلی
A Field Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that combines an array of configurable logic blocks, programmable interconnect, and I/O cells on a single CMOS die. The ACEX 1K family sits in the hierarchy: programmable logic device -> CPLD/FPGA -> SRAM-based FPGA -> ACEX 1K, representing one of the early low-cost, high-volume SRAM-lookup-table FPGA families from Altera (later acquired by Intel). Each logic element uses a 4-input LUT plus a register, and the embedded array blocks (EABs) can be configured as RAM, ROM, or multiplier primitives, allowing designers to mix datapath and control logic without external memory.
Key features include 4,992 logic cells / 624 CLBs, ~100 K system gates, 147 user I/Os, an embedded array block memory architecture, JTAG-based IEEE 1149.1 boundary-scan support, and an SRAM-based configuration cell that loads from a serial or parallel EPROM. The "-3" speed grade corresponds to the fastest commercial timing bin offered for this device family, enabling higher fMAX on internal logic and shorter pin-to-pin tPD delays than the slower -1 or -2 grades. The PQFP-208 package has a thermal resistance suitable for forced-air or large-copper PCB designs commonly used in telecom and industrial control chassis.
Typical applications include telecommunications line-card glue logic, industrial motor-control state machines, ASIC prototyping, DSP pre/post-processing pipelines, and legacy PCI/ISA bus-interface bridges where the 5 V-tolerant I/O and rich register fabric are advantageous. Designers often pair the EP1K100QI208-3 with an EPC2 configuration device to store the bitstream.
When designing with this part, ensure the JTAG chain is correctly ordered with any downstream devices, since multi-device scan chains are a common source of configuration failures. Verify the configuration mode (AS, PS, or JTAG) matches the EPC2 / EPC4 selected, and never apply VCC before the configuration device is stable.

کاربردهای معمول
EP1K100QI208-3 مناسب است برای 6 کاربردs: Telecommunications Line-Card Glue Logic, Industrial Motor Control State Machines, ASIC Prototyping and Emulation, DSP Pre-Processing and Post-Processing Pipelines, Legacy PCI / ISA Bus Interface Bridges, Test and Measurement Instrumentation Front-Ends.
Telecommunications Line-Card Glue Logic
The EP1K100QI208-3 is well-suited to telecom line-card glue logic where 147 user I/Os accommodate parallel bus interfaces to framers, TDM crossbars, and PHY devices. Its 4,992 logic cells and EAB-based RAM blocks can implement small FIFOs and elastic buffers between asynchronous domains. The PQFP-208 footprint is compatible with legacy 5 V-tolerant I/O banks, allowing direct interface to classic telecom backplanes. Industrial temperature grade supports outdoor cabinet deployments. The -3 speed bin delivers fMAX headroom for 155 Mbps POS/SDH glue, while remaining within timing closure on Quartus II synthesis flows.

Industrial Motor Control State Machines
Industrial motor drives demand deterministic state machines for PWM generation, fault handling, and CAN/RS-485 protocol bridging. The EP1K100QI208-3's 4,992 logic cells provide comfortable headroom for closed-loop current-control state machines plus encoder-decoder logic, while 147 I/Os interface to gate drivers, ADC data buses, and HMI displays. Industrial -40 to +85C rating tolerates drive-cabinet ambient temperatures. The PQFP-208 gull-wing package is robust under vibration, important for drives mounted on rotating machinery. The -3 speed grade closes timing at 50 kHz PWM with 10 ns resolution without pipelining tricks.
پیشنهادی
ASIC Prototyping and Emulation
Designers historically used ACEX 1K FPGAs as ASIC prototypes because the LUT-based fabric maps cleanly to synthesized ASIC gate libraries. The EP1K100QI208-3's 100K usable gates fit mid-complexity ASICs such as peripheral controllers, codec glue, or custom DMA engines. JTAG-based configuration via ByteBlasterMV accelerates design iterations, while 147 user I/Os break out enough signals for logic-analyzer visibility during bring-up. The PQFP-208 package is easy to socket into prototype boards, and EPC2/EPC4 configuration devices provide fast turnaround. Quartus II synthesis flows still accept legacy ACEX designs.

DSP Pre-Processing and Post-Processing Pipelines
The EAB blocks in the EP1K100QI208-3 can be configured as multipliers and small dual-port RAMs, enabling FIR filter pre/post-processing around an external fixed-point DSP. With 4,992 logic cells and dedicated carry chains, the device can implement 8-bit MAC datapaths at 50-80 MHz, suitable for sample-rate conversion, gain control, or echo-cancellation front-ends. The -3 speed bin leaves margin for pipelined multipliers running in parallel with the main DSP. Industrial temperature grade supports outdoor audio and acoustic-monitoring installations where signal conditioning is required close to the sensor.

Legacy PCI / ISA Bus Interface Bridges
The EP1K100QI208-3's 5 V-tolerant I/O banks make it ideal for legacy PCI/ISA bridges in industrial PCs and test equipment. Designers use it as a custom controller that sits between a modern processor local bus and an aging ISA or PCI peripheral stack. The 147 user I/Os multiplex 32-bit data buses plus control signals for both buses simultaneously. Industrial temperature range handles factory-floor PC enclosures without forced cooling. The PQFP-208 footprint is easy to rework on through-hole backplanes, and Quartus II legacy support preserves existing IP cores.
پیشنهادی
Test and Measurement Instrumentation Front-Ends
Test equipment such as protocol analyzers, logic-analyzer front-ends, and arbitrary waveform generators rely on FPGA-based state machines and timing generators. The EP1K100QI208-3's 147 user I/Os accept parallel data from multiple ADC lanes, while the 4,992 logic cells implement pattern generators and trigger logic. Industrial temperature range supports bench-to-field portability. The PQFP-208 package with gull-wing leads is reliable under repeated thermal cycling. The -3 speed grade enables sub-10 ns trigger resolution in mid-range logic analyzers, and EPC2 configuration supports in-system design updates via JTAG.

یادداشت‌های طراحی
The EP1K100QI208-3 requires a tightly regulated 2.5 V core supply (VCCINT) with a maximum of 2.625 V, plus separate VCCIO rails for each I/O bank (3.3 V typical for LVTTL, 2.5 V for SSTL). Place at least four 0.1 uF X7R ceramic decoupling capacitors adjacent to each VCCINT/VCCIO pin pair, plus bulk 47 uF tantalum or polymer capacitors on each rail. Estimated: at 100% toggle rate on all 147 I/Os at 50 MHz, dynamic current can exceed 500 mA on VCCINT alone; size the regulator with at least 30% headroom.
The PQFP-208 package has gull-wing leads on a 0.5 mm pitch. Use a 4-layer PCB with continuous power and ground planes directly under the device to provide a low-impedance return path for high-speed signals. Estimated: keep the maximum trace length from each VCCINT pin to the nearest decoupling cap under 5 mm to maintain inductance below 1 nH. Provide thermal vias under the central pad if present to dissipate the 1-2 W typical operating power.
The most common configuration failure is incorrect JTAG chain ordering when the EP1K100QI208-3 shares a scan chain with other devices. Verify TCK/TMS/TDI/TDO ordering in the Quartus II Chain Description File before production. Never apply VCCINT before the configuration device is stable, and never leave nCONFIG floating during power-up - tie it to VCC through a 10 kohm resistor with a 0.01 uF bypass capacitor to ground. Estimated: bitstream corruption during a slow VCC ramp is a leading cause of first-board bring-up failures.
