EP1K100QI208-02 Übersicht
An FPGA (Field Programmable Gate Array) is a type of programmable logic device (PLD) that combines an array of configurable logic blocks (LABs), embedded memory, and programmable interconnect into a single semiconductor IC. FPGAs belong to the broader hierarchy: programmable logic device -> field programmable gate array -> SRAM-based FPGA -> ACEX-1K family. Unlike ASICs, FPGAs are reprogrammable in-system, which makes them ideal for prototyping, low-volume production, and designs where hardware requirements evolve over time.
The EP1K100QI208-02 provides 624 Logic Array Blocks (LABs), each containing 8 Logic Elements (LEs) for a total of 4,992 LEs. Embedded array blocks (EABs) deliver up to 24 Kbits of dual-port RAM per EAB, configurable as RAM, ROM, or FIFO. The device supports in-system configuration via serial or parallel configuration devices, JTAG boundary-scan testing (IEEE 1149.1), and MultiVolt I/O supporting 2.5 V, 3.3 V, and 5 V interfacing, eliminating the need for external level translators in mixed-voltage systems.
Architecturally, the ACEX-1K family was the industry's first FPGA to embed dedicated dual-port RAM blocks (EABs), enabling efficient memory-intensive functions such as FIFOs, look-up tables, and DSP-style filtering without consuming logic resources. The 0.22 µm process combined with 2.5 V core reduced power consumption relative to 5 V FPGAs of the era, while the high I/O count (147 user I/Os) makes the device suitable for bus-intensive glue logic, peripheral bridging, and legacy industrial control applications.
Typical applications include telecommunications line-card interface glue logic, industrial machine control and instrumentation, ASIC prototyping, peripheral bus bridges (PCI-to-ISA, UART muxing), low-cost digital signal processing front-ends, and embedded control logic. The 208-pin PQFP package is through-hole-friendly and easy to hand-prototype, though it occupies significant PCB area compared to later BGA packages. The wide MultiVolt I/O range also makes the part common in mixed 3.3 V/5 V systems.
When designing with the EP1K100QI208-02, note that the "-02" speed grade has the slowest timing margins - it is suitable for designs clocked at 100 MHz or below, but applications requiring 200 MHz+ should select the "-1" speed grade. ACEX-1K devices are now in their end-of-life (EOL) era; for new designs, current Altera/Intel families such as Cyclone IV, MAX 10, or Cyclone V are recommended replacements.

Typische Anwendungen
EP1K100QI208-02 ist geeignet für 6 Anwendungs: Telecommunications Line-Card Glue Logic, Industrial Machine Control, ASIC Prototyping and Emulation, Peripheral Bus Bridges (PCI/ISA/UART), Low-Cost Digital Signal Processing Front-End, Embedded Control Logic.
Telecommunications Line-Card Glue Logic
The EP1K100QI208-02 fits telecommunications line-card glue logic because its 100K gates and 147 user I/Os let designers integrate bus bridges, framers, and protocol converters without external ASICs. The device's MultiVolt I/O bank supports 2.5 V/3.3 V/5 V interfacing, which eliminates external level shifters in mixed-voltage TDM/SONET designs. The 49,152 bits of embedded dual-port RAM support small FIFO buffers and elastic stores common in serial protocol backplanes. Estimated: at a 100 MHz system clock with 50% I/O toggling, expect roughly 0.5-1 W of core dissipation. Choose -02 speed grade only when timing margins above 150 MHz are not required.
Empfohlen
Industrial Machine Control
The EP1K100QI208-02 is well-suited to industrial machine control where its Industrial temperature rating (-40C to +85C), 147 I/Os, and 100K-gate capacity enable integration of motor-control glue logic, sensor multiplexing, encoder counters, and safety interlocks on a single chip. The ACEX-1K family was widely deployed in PLC peripheral cards and CNC controllers because the MultiVolt I/O allowed direct connection to 24V-tolerant industrial sensors via external resistive dividers. The 208-PQFP package is hand-solderable for prototype repairs in the field. Estimated: at 100% I/O utilization in an enclosed cabinet, derate junction temperature by 10-15C beyond ambient.
Empfohlen
ASIC Prototyping and Emulation
The EP1K100QI208-02 serves as an excellent ASIC prototyping vehicle because its 100K-gate capacity, JTAG boundary scan, and SRAM-based in-system reconfiguration allow rapid iteration of pre-silicon designs. The dual-port EAB RAM blocks enable efficient emulation of register files and small cache structures. The 208-PQFP package is also useful in socketed prototype boards because engineers can swap parts during multi-FPGA logic partitioning. Engineers commonly used ACEX-1K devices as 'satellite' FPGAs around larger APEX or Stratix devices in multi-FPGA emulation rigs. The -02 speed grade is adequate when emulating ASICs clocked at 50-100 MHz.
Empfohlen
Peripheral Bus Bridges (PCI/ISA/UART)
The EP1K100QI208-02's 100K-gate density and MultiVolt I/O make it ideal for legacy peripheral bus bridges such as PCI-to-ISA, UART multiplexing, and parallel-port expansion. The 147 user I/Os are sufficient to implement a 32-bit PCI bus (94 pins for address/data plus control) with headroom for side-band signals. The dual-port EAB memory blocks efficiently implement small FIFOs needed between asynchronous clock domains. The 208-PQFP package was the standard footprint for PCI add-in card prototypes in the late 1990s and early 2000s. Estimated: a full 32-bit PCI target bridge uses roughly 60-70% of the device's logic capacity.
Empfohlen
Low-Cost Digital Signal Processing Front-End
The EP1K100QI208-02 supports moderate DSP front-end applications such as FIR filtering, correlation, and FFT pre-processing because its EAB blocks can implement efficient multiplier-accumulator shift-register chains. While it lacks dedicated DSP blocks (introduced later in Cyclone II/Stratix families), 100K gates and 49 Kbits of dual-port RAM allow modest filter sizes of up to 64 taps in 16-bit precision. The MultiVolt I/O lets the FPGA interface directly to 3.3 V ADCs. According to the ACEX-1K datasheet, the device can implement digital down-converters for narrow-band receivers. The -02 speed grade limits sample rates to roughly 50 MSPS.
Empfohlen
Embedded Control Logic
The EP1K100QI208-02 integrates custom peripheral controllers, custom interrupt controllers, and bus arbiters alongside a microprocessor or microcontroller in embedded systems. The 147 user I/Os let the FPGA expand the processor's peripheral count without glue-logic MSI parts. The dual-port RAM blocks implement mailbox registers and parameter-passing FIFOs between the CPU and custom logic. Industrial temperature grade makes it suitable for automotive under-hood, aerospace, and ruggedized military embedded controllers. Estimated: a custom 16-bit ISA-style peripheral bus consumes 30-40% of the LEs; two UARTs add another 20-25%.

Wichtigste Unterscheidungsmerkmale
- Industrial temperature grade for harsh environments (vs. EP1K100QC208-2N)
- -02 speed grade offers cost savings on non-timing-critical designs (vs. EP1K100QC208-1N)
- 208-PQFP package is hand-prototype-friendly (vs. EP1K100FC256-2 (256-FBGA))
Designhinweise
Estimated: the EP1K100QI208-02 typically draws 100-300 mA from the 2.5 V VCCINT rail depending on toggle rate and logic utilization. Add 100uF bulk + 0.1uF + 1uF decoupling per VCCINT pin. The VCCIO pins (2.5V/3.3V/5V depending on bank configuration) should each have a 0.1uF + 10uF decoupling cap. According to the ACEX-1K datasheet, inrush during configuration can briefly spike to 500 mA - size the regulator accordingly. Use a linear LDO for low-noise designs; the part is too old for modern DC-DC recommendations, but a TPS7A47xx-class LDO would suffice.
Estimated: at full I/O toggling (147 outputs @ 50 MHz, 50% activity) the EP1K100QI208-02 dissipates roughly 0.8-1.2 W. The 208-PQFP has theta_JA approximately 30-35 C/W in still air, yielding 25-40 C junction rise above ambient. For -40C to +85C industrial operation this is acceptable; for closed-enclosure designs, ensure at least 5 CFM airflow or use thermal vias to a copper inner-plane heatsink. Avoid placing the device adjacent to high-heat sources such as DC-DC converters.
Use a 4-layer PCB with continuous ground and power planes. Route all 208 pins with at least 8 mil trace width and 12 mil clearance. Place configuration device (EPC2 or similar) within 4 inches of the FPGA's configuration pins (nCONFIG, nSTATUS, CONF_DONE, DCLK, DATA) to avoid signal-integrity issues. Per the ACEX-1K datasheet, the JTAG chain (TCK, TMS, TDI, TDO) must be impedance-controlled and 0.1uF-bypassed near each device in the chain. Keep JTAG traces away from clock lines to minimize crosstalk.
Do not confuse the EP1K100QI208-02 with the EPF10K100EQI208-2 - the former is ACEX-1K (2.5V core) while the latter is FLEX 10KE (5V core), and they have different pinouts despite both being 208-pin PQFP. Verify the exact prefix before PCB assembly. Also note that ACEX-1K is volatile and requires configuration on every power-up - a boot PROM (EPC2, EPC8, EPC16) is mandatory, not optional. The device cannot retain configuration through power cycles like a CPLD.
Compliance-Informationen
ACEX-1K is a legacy Altera family; the EP1K100QI208-02 part number does not include the -N lead-free suffix that would indicate RoHS compliance. For RoHS-compliant variants choose EP1K100QI208-2N. AEC-Q100 not applicable - ACEX-1K predates the AEC-Q100 automotive qualification standard adoption.
