EP1K30QI208-3N Visão geral
An FPGA (Field-Programmable Gate Array) is a programmable logic device that combines the integration density of a gate array with the flexibility of in-system reprogrammability. ACEX 1K sits in the low-to-mid density FPGA tier, positioned between simple CPLDs and high-density SRAM-based FPGAs, and is widely used for interface bridging, custom peripheral expansion, and DSP pre-processing on cost-sensitive industrial boards. The -3N speed grade and industrial temperature rating (-40 °C to +85 °C) target factory automation, telecom peripherals, and long-life industrial equipment.
Key features include 24,576 RAM bits, 6 Embedded Array Blocks, dual LVTTL/LVCMOS I/O support, JTAG-based in-system programmability via the IEEE 1149.1 boundary-scan chain, and on-chip clock-management PLLs that simplify multi-clock designs. The 208-pin PQFP package with 0.5 mm pitch is a through-hole-friendly plastic package suitable for socketed prototypes and lower-density production runs where BGA rework costs are unacceptable.
Architecturally, ACEX 1K devices embed logic array blocks (LABs) backed by continuous SRAM configuration memory, which is loaded at power-up from a serial configuration EPROM such as the EPC2 or EPC8. This volatile configuration model makes the EP1K30QI208-3N ideal for designs where configuration flexibility, fast prototyping, and iterative revision outweigh the need for non-volatility. MultiVolt I/O allows 3.3 V, 2.5 V, and 1.8 V interfacing without external level shifters.
Typical applications include industrial PLC interface cards, telecom line-card glue logic, medical instrument front-panel controllers, legacy parallel-bus bridges, and compact PCI peripheral controllers. The wide operating voltage tolerance and rugged PQFP package also make it a popular retro-fit for older Altera designs that are being re-spun onto current revision hardware without a layout re-spin.
When designing with this device, remember that the configuration is volatile - a boot PROM or microcontroller is mandatory. The 0.5 mm PQFP pitch can be hand-soldered with a fine-tip iron, but production assembly requires careful solder-paste stencil design and bottom-side preheat profiling to avoid tombstoning the fine-pitch leads.
This page synthesizes distributor stock levels, ACEX 1K family cross-references, drop-in pin-compatible alternatives, and practical layout guidance not found in the original datasheet - useful both for new designs and for sustaining older industrial systems that depend on this long-life part.

Aplicações típicas
EP1K30QI208-3N é adequado para 6 aplicaçãos: Industrial PLC Interface Cards, Telecom Line-Card Glue Logic, Medical Instrument Front-Panel Controllers, Legacy Parallel-Bus Bridges, Compact PCI Peripheral Controllers, Retrofit of Legacy Altera Designs.
Industrial PLC Interface Cards
The EP1K30QI208-3N suits industrial PLC interface cards that must bridge legacy parallel buses (PC/104, ISA, VME) to modern backplanes. With 147 user I/O pins and 6 dedicated inputs, the device can absorb multi-port handshake logic, custom protocol converters, and encoder/decoder blocks that would otherwise require several discrete PALs and glue logic. The 30K-gate density leaves margin for interrupt controllers and mailbox FIFOs, while the industrial -40 C to +85 C rating handles factory-floor thermal stress. Unlike a CPLD, the FPGA can host multiple parallel state machines without routing congestion. Typical designs use the EP1K30 as the I/O concentrator between an embedded SBC and the analog I/O stage.
Recomendado
Telecom Line-Card Glue Logic
In telecom line cards, the EP1K30QI208-3N is commonly used to consolidate HDLC controllers, framer glue, alarm scanners, and timeslot crossbar switches onto a single programmable device. The 24,576 RAM bits are sufficient to hold small FIFOs for traffic shaping on T1/E1 backplanes, and the MultiVolt I/O simplifies 3.3 V to 5 V interfacing with legacy framer ASICs without external level shifters. The -3 speed grade comfortably meets E1 (2.048 MHz) and T1 (1.544 MHz) backplane timing with several hundred MHz of internal fMAX headroom. Industrial temperature handling supports outside-plant cabinets and central-office deployments.
Recomendado
Medical Instrument Front-Panel Controllers
The EP1K30QI208-3N fits medical instrument front panels that need to debounce keypads, drive character LCDs, multiplex LED arrays, and buffer serial links to the main processor. The 147 user I/O count easily covers a 4x5 keypad scan matrix, parallel LCD interface, and dedicated indicator LEDs, while the SRAM-based configuration allows last-minute UI customization without board respins. With 1,728 logic elements, designers can also embed a small timer/counter chain for infusion-pump or patient-monitor subsystems. Industrial temperature grading plus lead-free PQFP packaging meets hospital equipment reliability expectations.
Recomendado
Legacy Parallel-Bus Bridges
The EP1K30QI208-3N is widely deployed as a bus bridge between legacy microcontrollers (8051, 68K, MIPS) and modern peripherals such as SDRAM controllers, Ethernet MACs, or USB device chips. The FPGA absorbs wait-state insertion, address decoding, and chip-select generation in hardware, freeing the host CPU from interrupt-driven bus emulation. The 208-pin PQFP footprint is large enough to expose dedicated control pins for bus request/grant, while 24,576 RAM bits can hold small mailbox FIFOs between the two domains. Engineers upgrading old designs use the FPGA to extend product life without an ASIC re-spin.
Recomendado
Compact PCI Peripheral Controllers
In Compact PCI and PMC mezzanine designs, the EP1K30QI208-3N acts as a custom peripheral controller implementing protocol adaptation, DMA handshaking, and local interrupt arbitration. The 147 user I/O plus dedicated clock inputs map neatly onto PCI local-bus signals and provide additional general-purpose lines for mezzanine I/O expansion. The -3 speed grade delivers sufficient timing margin for 33 MHz PCI operation, while the industrial temperature rating supports chassis temperature requirements. Volatile SRAM configuration means designers can update firmware personality in the field without re-soldering.
Recomendado
Retrofit of Legacy Altera Designs
Many long-life industrial products continue to specify the EP1K30QI208-3N for retrofit and sustaining-engineering builds. Because the 208-pin PQFP footprint, configuration sequence, and Quartus toolchain support have remained stable across ACEX 1K die revisions, designers can swap equivalent speed grades without rerunning timing closure from scratch. The drop-in nature of the EP1K30QI208-2N (faster speed grade) and EP1K30QC208-3N (commercial temp) makes the family a flexible sustainment platform. The lead-free PQFP package aligns with current RoHS reflow profiles even on boards designed before 2006.

Notas de projeto
The EP1K30QI208-3N core runs on a 2.5 V supply (VCCINT, 2.375-2.625 V) while VCCIO pins must be tied to 3.3 V, 2.5 V, or 1.8 V depending on the I/O standard chosen. Decouple every VCCINT/VCCIO pair with a 0.1 uF ceramic placed within 5 mm of the package pin, plus a bulk 10-100 uF tantalum or polymer cap on each rail. Estimated: ICCINT for a fully utilized EP1K30 is on the order of 100-200 mA at 2.5 V plus I/O switching current; design the 2.5 V regulator for at least 500 mA of headroom to avoid voltage droop during configuration bursts.
The 208-pin PQFP at 0.5 mm pitch demands a 4-layer PCB with continuous power planes underneath the package. Fan-out the fine-pitch leads on the outer top layer using short, equal-length traces with a maximum 1:1 trace-to-pad aspect ratio to maintain manufacturing yield. Add a 5 mm keep-out around the package body for probe access, and place the EPC2/EPC8 configuration PROM within 50 mm of DCLK/DATA0/nCONFIG to avoid signal-integrity issues during configuration.
JTAG chain integrity is critical for ACEX 1K in-system programming. TMS and TDI should be weakly pulled up to VCCIO via 10 kohm resistors to keep the JTAG state machine in a known state during power-up. TCK should be routed as a controlled-impedance trace with a series 33 ohm damping resistor at the driver. The nCONFIG line must be held low for at least 8 us after VCCINT stable to ensure a clean configuration cycle, and CONF_DONE should be weakly pulled high to detect configuration failures.
Do not confuse the EP1K30QI208-3N (industrial -40 to +85 C, speed grade -3) with the EP1K30QC208-3N (commercial 0 to +70 C, speed grade -3) - the part numbers look nearly identical. Do not assume configuration memory is non-volatile - without an external EPC2/EPC8 PROM the device powers up unconfigured and all I/O will be tri-stated. Finally, do not hot-swap the configuration PROM in-circuit; always assert nCONFIG low before reprogramming to avoid bus contention on the configuration pins.
