EP1K30TC1443N Ringkasan

The Altera EP1K30TC1443N is a member of the ACEX 1K family of field-programmable gate arrays (FPGAs), delivering 30,000 typical gates and 1,728 logic elements in a 144-pin TQFP (Thin Quad Flat Pack) package. It is fabricated on a 0.22-micron CMOS process, operates from a 2.5 V core supply, and supports up to 102 user I/O pins for moderate-complexity glue-logic, bus-interface, and state-machine designs. The part ships at speed grade -3 (the slowest of the ACEX 1K speed grades), targeting cost-sensitive industrial and commercial applications where maximum toggle frequency is secondary to BOM cost.

An FPGA (Field-Programmable Gate Array) is a reconfigurable integrated circuit containing an array of configurable logic blocks (CLBs), programmable interconnect, and I/O cells that the designer can wire into arbitrary digital circuits after manufacture. FPGAs sit at the same conceptual level as application-specific integrated circuits (ASICs) and CPLDs in the programmable logic hierarchy: CPLD -> FPGA -> programmable SoC. Within the broader semiconductor taxonomy, FPGAs are a sub-category of digital logic ICs, distinct from ASICs (which are mask-programmed and not field-reprogrammable) and from microcontrollers/MPUs (which run software on a fixed hardware core).

Key features of the EP1K30TC1443N include 1,728 logic elements (LEs), 24 Kbits of embedded SRAM organized as true dual-port RAM blocks, 102 maximum user I/O pins, and JTAG-based IEEE 1149.1 boundary-scan / in-system programmability via the Altera (now Intel) Quartus design suite. The device supports hot-socketing insertion and LVCMOS/LVTTL I/O standards, simplifying mixed-voltage PCB integration with 3.3 V and 5 V peripherals.

Architecturally, the ACEX 1K family embeds an array of Logic Array Blocks (LABs), each containing ten LEs with a carry-chain and cascade-chain for fast arithmetic and wide fan-in logic. Distributed SRAM and embedded array blocks (EABs) provide on-chip memory for FIFOs, lookup tables, and small register files without consuming LE resources. The 2.5 V core with separate VCCIO banks allows the die to interface to 2.5 V, 3.3 V, and 5 V system logic without external level shifters, an important advantage over older 5 V-only ACEX predecessors.

Typical applications include industrial control glue logic, JTAG-based protocol bridges (I2C/SPI/UART to parallel), low-volume ASIC replacement in test and measurement equipment, custom state-machine controllers in motor drives, and educational FPGA platforms where the TQFP-144 footprint is preferred for hand-soldering or low-cost breakout boards. The ACEX 1K family was the industry's first FPGA to use embedded SRAM blocks alongside LE-based logic.

When designing with the EP1K30TC1443N, ensure that the Quartus version supports the ACEX 1K device family (Quartus II 13.0 or earlier; newer Quartus releases have dropped ACEX 1K support - see _validation_note). Pin assignment files should be regenerated in the original Quartus II toolchain to avoid compile errors. The TQFP-144 footprint is hand-solderable with standard reflow profiles, but exposed-pad variants of later Cyclone families are not drop-in compatible.
