EP1K50TI144-2 개요
An FPGA (Field Programmable Gate Array) is a semiconductor integrated circuit composed of configurable logic blocks (CLBs), programmable interconnects, and I/O cells that can be re-programmed to implement arbitrary digital logic. ACEX-1K sits within the broader taxonomy of programmable logic devices (PLDs) -> complex programmable logic devices (CPLDs) / FPGAs -> SRAM-based LUT FPGAs -> low-cost FPGAs -> embedded array FPGAs. The EP1K50TI144-2 specifically uses a Look-Up Table (LUT)-based architecture with embedded array blocks (EABs) that support dual-port RAM, ROM, FIFO, and specialized megafunctions, enabling system-on-a-programmable-chip (SOPC) integration.
Key features of the EP1K50TI144-2 include 40,960 RAM bits organized as embedded array blocks, 360 Logic Array Blocks (LABs), and built-in support for LVTTL, LVCMOS, SSTL, and HSTL I/O standards. The device also integrates a JTAG boundary-scan test interface compliant with IEEE 1149.1, an in-system programmability (ISP) port, and a dedicated configuration circuitry that accepts bitstreams from EPC configuration PROMs or via passive serial/parallel controllers.
Typical applications for the EP1K50TI144-2 include glue-logic replacement, industrial control interfaces, low-density telecommunications glue logic, and bridge/protocol conversion such as UART-to-PCI or I2C-to-parallel. The 144-LQFP package is hand-solder-friendly and compatible with low-cost PCB fabrication, making it well-suited for prototype runs and legacy system maintenance. Designers migrating to this part should note that ACEX-1K devices in the same 144-pin TQFP/LQFP package are pin-compatible across the family, allowing migration between EP1K10, EP1K30, and EP1K50 density points on the same PCB layout.
This page synthesizes distributor pricing, ACEX-1K family pin-compatible alternatives, and practical design notes for the EP1K50TI144-2 that are not collated in the legacy ACEX 1K Device Family datasheet.

일반적인 애플리케이션
EP1K50TI144-2 적합 용도: 6 애플리케이션s: Industrial Glue Logic Replacement, Legacy Protocol Bridge and Bus Converter, Test and Measurement Instrumentation Front-End, Telecommunications Glue Logic and Framing, Motor Control and Drive Interface, Aerospace Prototype and Avionics Bus Interface.
Industrial Glue Logic Replacement
The EP1K50TI144-2 is well suited for replacing multiple discrete 74-series glue-logic ICs in industrial control boards. With 2,880 LEs and 102 user I/O pins, the device can absorb an entire 7400-series BOM (buffers, latches, transceivers, encoders) into a single chip, cutting PCB area by 60-70% and reducing component count. Its 2.5 V core and LVTTL/LVCMOS I/O support connect directly to legacy 3.3 V microcontrollers and 5 V peripherals via series resistors. Designers should budget for an EPC2/EPC8 boot PROM and 4-layer PCB for signal integrity.
추천
Legacy Protocol Bridge and Bus Converter
The EP1K50TI144-2 fits protocol-bridge designs such as UART-to-PCI, I2C-to-parallel, or SPI-to-ISA conversion used in legacy telecom and industrial equipment. The 40,960 bits of embedded RAM accommodate FIFOs up to 5 KB without external SRAM, and the 360 LABs deliver deterministic propagation delays suitable for bit-banging legacy bus timing. The 144-LQFP package is hand-rework-friendly for field upgrades, and SameFrame pin-compatibility lets engineers migrate to EP1K100TI144-2 in the same PCB footprint as bridge complexity grows.
추천
Test and Measurement Instrumentation Front-End
The EP1K50TI144-2 serves as the digital back-end for low-cost test instruments such as logic analyzers, pattern generators, and protocol exercisers. Its 102 I/O pins support up to 96 channels of buffered digital I/O at 50 MHz using the -2 speed grade, sufficient for capturing parallel bus traffic at up to 25 MHz. The 2.5 V core delivers low dynamic power (~0.5 W typical) compared to larger FPGAs, making the part attractive for portable or USB-powered instruments. Designers typically implement state machines for trigger sequencing and store captured data in the embedded EAB RAM.
추천
Telecommunications Glue Logic and Framing
In legacy telecom systems (T1/E1 framers, DS3 multiplexers, SONET/SDH tributary equipment), the EP1K50TI144-2 handles framing, alarm insertion, and clock-data recovery glue logic. The 360 LABs run small HDLC controllers and bit-error-rate testers (BERTs) in parallel, while the 40,960 bits of embedded RAM buffer tributary payloads. The -2 speed grade comfortably meets 51.84 MHz STS-1 timing. Industrial temperature grade supports outside-plant and central-office deployments where ambient temperatures vary.
추천
Motor Control and Drive Interface
The EP1K50TI144-2 is deployed as the digital interface between microcontrollers/MOSFET gate drivers in industrial motor drives, BLDC controllers, and stepper drivers. The 102 I/O pins handle quadrature encoder feedback (QEP), Hall-sensor inputs, PWM outputs to gate drivers, and fault interlocks all within a single chip. Industrial-temperature operation (-40 to +85 °C) tolerates the elevated ambient inside a drive enclosure. The 2.5 V core and 3.3 V I/O simplify interface to modern Cortex-M microcontrollers, and embedded EABs store sine-table and commutation look-up tables.
추천
Aerospace Prototype and Avionics Bus Interface
The EP1K50TI144-2 is used in legacy aerospace prototypes for ARINC 429, MIL-STD-1553, and discrete avionics bus interface cards. The 2,880 LEs encode/decode up to 8 ARINC 429 channels or implement a single MIL-STD-1553 BC/MT/RT in soft logic, while the industrial temperature range covers most cockpit and equipment-bay environments. SameFrame pin-compatibility lets designers scale to EP1K100TI144-2 for higher-channel-count avionics boxes without PCB rework. Note that aerospace certification programs typically require an obsolescence-management plan given the part's end-of-life status.

설계 노트
The EP1K50TI144-2 requires a clean 2.5 V core supply (VCCINT) capable of delivering up to 300 mA during configuration and up to 200 mA in steady-state operation. Use a low-dropout regulator such as a TI TPS79325 or LT3021 with at least 25% current headroom. Place 10 µF + 0.1 µF decoupling capacitors within 5 mm of every VCCINT/GND pair. VCCIO must ramp within ±600 µs of VCCINT to avoid latch-up; sequence VCCINT before VCCIO or use a dual-output LDO with tracking.
The 144-LQFP package has 0.5 mm pitch leads; PCB land pattern must follow IPC-7351 nominal-density guidelines with 0.30 mm pad width and 0.20 mm solder mask sliver. Use a 4-layer stackup with a continuous ground plane under the device. Tie all unused I/O pins to logic-low or logic-high through the Quartus II assignment editor (do not leave them floating). Add a 4.7 kΩ pull-up to VCCIO on nCONFIG, nSTATUS, and CONF_DONE for reliable boot.
Three common pitfalls: (1) Failing to populate an EPC configuration PROM and assuming the FPGA will boot from internal flash - the EP1K50TI144-2 is SRAM-based and loses configuration on every power-cycle. (2) Mixing VCCIO and VCCINT rails - the I/O bank voltage must match the peripheral logic level, otherwise inputs will be clamped and outputs will be over-driven. (3) Using a non-validated JTAG programmer (such as a generic FT2232H-based cable) without an Altera-compatible buffer - the TCK signal is sensitive to cable capacitance above 25 pF, which causes configuration failures.
