EP1K50TI144-2 - 50K-Gate ACEX-1K FPGA, 102 I/O, 144-LQFP | Intel
MPN: EP1K50TI144-2 ✗ Cuối đờiEP1K50TI144-2 Tóm tắt
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.

Ứng dụng tiêu biểu
EP1K50TI144-2 phù hợp cho 6 Áp dụngs: 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.
Được đề xuất
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.
Được đề xuất
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.
Được đề xuất
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.
Được đề xuất
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.
Được đề xuất
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.

Ghi chú thiết kế
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.
