EP1K50TI144-2N Ringkasan

The Intel / Altera EP1K50TI144-2N is a member of the ACEX-1K family of Field Programmable Gate Arrays (FPGAs), delivering 50,000 typical gates (40,960 logic elements) and 2,880 cells of embedded array in a 144-pin Thin Quad Flat Pack (TQFP) package. It provides 102 user I/O pins, 360 Logic Array Blocks (LABs), and is fabricated on a 0.22 µm process technology targeting a maximum internal operating frequency around 166.67 MHz. The "-2N" suffix denotes the device speed grade (faster) and the "N" indicates an industrial operating temperature range.

An FPGA (Field Programmable Gate Array) is a class of programmable logic device (PLD) that combines the architectural flexibility of gate arrays with the design-turnaround benefits of user-programmability. In the system hierarchy, FPGAs sit between discrete logic (small-scale glue logic) and fixed-function Application-Specific Integrated Circuits (ASICs), offering a balance of density, performance, and reconfigurability. ACEX-1K was Altera's second-generation SRAM-based FPGA family and is a hypernym of CPLDs within the broader programmable logic taxonomy.

Key features of the EP1K50TI144-2N include 12 embedded system blocks (ESBs) providing 6 Kbits of dedicated RAM per block, support for multiple I/O standards (LVTTL, LVCMOS, PCI, and others), in-system programmability via IEEE 1149.1 JTAG, and built-in clock management. The device is configured via a serial configuration EPROM (EPC) or the IEEE 1149.1 boundary-scan interface, supporting both SRAM-based and JTAG programming flows.

Typical applications include glue logic replacement, interface bridging, custom state-machine implementation, low-to-medium density data-path processing, and prototyping platforms that can later be ported to higher-density Cyclone or newer Altera/Intel FPGA families. The 144-TQFP package supports traditional surface-mount assembly with a generous 0.5 mm pitch suitable for rework.

When designing with this part, note that ACEX-1K is an older, mature family; verify that current Altera/Intel Quartus software supports the device and confirm long-term availability before committing to new designs. The 144-TQFP package is also convenient for hand-soldered prototypes.

🔧

Glue Logic Replacement and Bus Interface Bridging

The EP1K50TI144-2N is well-suited as a drop-in replacement for multiple discrete 74-series logic ICs on legacy boards. With 50K gates and 102 user I/O in a 144-TQFP, a single EP1K50TI144-2N can replace dozens of buffers, latches, transceivers, and custom state machines. The 2.5 V core with multi-standard I/O (LVTTL/LVCMOS/PCI) lets it bridge 3.3 V, 5 V, and mixed-voltage buses without external level shifters. For example, on a 16-bit ISA-to-PCI bridge card, the FPGA implements latches, address decoding, and timing in one chip, reducing BOM cost and board area while adding design flexibility via SRAM reconfiguration.

What is the maximum operating frequency of EP1K50TI144-2N?
The EP1K50TI144-2N has a maximum internal operating frequency of approximately 166.67 MHz, according to Altera/Intel ACEX-1K family datasheet specifications. Actual system frequency depends on the design's logic depth, routing path, and I/O standard selected. The "-2" speed grade identifies this part as one of the faster ACEX-1K speed bins.
How many user I/O pins does EP1K50TI144-2N have?
The EP1K50TI144-2N provides 102 user I/O pins in a 144-pin TQFP package. Of the 144 physical package pins, 102 are dedicated user I/O, the remainder are supply, ground, configuration, and JTAG pins. When planning PCB layout, refer to the pinout table for the exact mapping and reserved pins for the EPC configuration device.
How many logic elements and gates does EP1K50TI144-2N have?
The EP1K50TI144-2N contains 40,960 logic elements (LEs) / 2,880 cells and is rated at 50,000 typical gates. The 360 Logic Array Blocks (LABs) group these LEs, with each LAB containing 8 LEs and supporting interconnect and local control signals. This places it as a mid-density member of the ACEX-1K family.
Where can I download the EP1K50TI144-2N datasheet?
The EP1K50TI144-2N datasheet can be downloaded as a PDF from third-party archival sites including alterasemi.com and datasheets.com, linked from the XAIPART product page. For the original Altera ACEX-1K Device Handbook (which covers this device), consult Intel's Programmable Solutions Group archive. Note that Intel discontinued active support of this mature family.
What is the pinout of EP1K50TI144-2N?
The EP1K50TI144-2N pinout is documented in the ACEX-1K Device Handbook, with 144 TQFP pins arranged as 36 leads per side at 0.5 mm pitch. Pin functions include 102 user I/O (I/O[0..101]), dedicated configuration pins (nCONFIG, nSTATUS, CONF_DONE, MSEL[0..1], nCE, DCLK), JTAG pins (TCK, TMS, TDI, TDO, TRST), and supply/ground. Refer to the official datasheet pin table for exact assignments.
What is the difference between EP1K50TI144-2N and EP1K50TI144-2?
The EP1K50TI144-2N (with "N" suffix) indicates the industrial operating temperature range of -40C to +85C, whereas the EP1K50TI144-2 (without "N") is the commercial temperature grade (0C to +70C). Both share the same 144-TQFP package, 50K-gate density, 102 user I/O, and -2 speed grade, making them drop-in compatible on PCB with only a firmware/ordering code distinction.
What is the difference between EP1K50TI144-2N and EP1K50TC144-3N?
The EP1K50TI144-2N uses the TQFP package and -2 speed grade, while the EP1K50TC144-3N uses the same TQFP package but the slower -3 speed grade. Both share 50K gates, 144 pins, and 102 user I/O. Choose -2 for higher performance; choose -3 (or higher speed bin numbers) for lower cost. Both are pin-compatible in TQFP, but speed selection requires re-fitting the timing constraints in Quartus.
Can I replace EP1K50TI144-2N with a newer FPGA such as MAX 10?
A direct drop-in replacement for the EP1K50TI144-2N in a MAX 10 family is not possible because the packages, pinouts, and configuration schemes differ. According to Intel Community discussion threads, migration typically requires PCB redesign and recompilation in Quartus Prime with a different target device. As a drop-in alternative within the ACEX-1K family, EP1K50TI144-2 (commercial temp) and EP1K50TC144-2N are pin-compatible on the same 144-TQFP footprint.
Is EP1K50TI144-2N still in production or obsolete?
The EP1K50TI144-2N is classified as Not Recommended for New Designs (NRND) by Intel/Altera and is approaching end-of-life. Stock remains at a few distributors (DigiKey, Micro-Semiconductor, Heisener, Nantian, Veswin), but lead times may extend. For new designs, consider the Cyclone IV/V or MAX 10 families; for sustaining legacy designs, place orders for lifetime buy quantities while stock is available.
What is the price of EP1K50TI144-2N as of 2026?
The EP1K50TI144-2N list price as of 2026-09-07 is approximately $18.50 USD at qty 1, dropping to $9.95 USD at qty 1,000. Prices vary by distributor; check Octopart or DigiKey for live quotes. Because this part is NRND, price trends upward as inventory depletes; locking in lifetime buy at the lowest visible qty break is a common risk-mitigation strategy.
Where to buy EP1K50TI144-2N online?
The EP1K50TI144-2N can be purchased from authorized distributors including DigiKey, Mouser, Micro-Semiconductor, Heisener, Nantian Electronics, Veswin Electronics, and Octopart-aggregated inventory. As of 2026-09-07, several vendors show stock; quote multiple sources because pricing fluctuates rapidly for NRND parts.
What is the lead time for EP1K50TI144-2N?
Lead time for the EP1K50TI144-2N is unpredictable because the part is NRND and stock varies by distributor. Some vendors ship immediately from on-hand inventory, while others may have 8-12 week lead times once stock is depleted. Always confirm current lead time at order entry, and consider placing a lifetime-buy order if you are sustaining production.
Is EP1K50TI144-2N RoHS compliant?
The EP1K50TI144-2N is from an older ACEX-1K family that predates the RoHS mandate, so some date codes may not be RoHS-compliant (leaded). Newer date codes and orderable parts generally carry RoHS-compliant finish, but you must verify with the specific lot/date code before PCB assembly. Check the manufacturer's Certificate of Compliance for the exact lot in question.
Is EP1K50TI144-2N pin-compatible with EP1K100TI144-2N?
Higher-density ACEX-1K members such as EP1K100 (100K gates) in the 144-TQFP share pin compatibility for common user I/O pins, following Altera's SameFrame pin-migration strategy. However, additional I/O pins on the larger device cannot be used on the 144-TQFP footprint because they are not bonded out. For pure drop-in on the existing 144-TQFP PCB, EP1K50TI144-2N may be replaced by EP1K50TI144-2 (commercial grade) with no PCB changes.
What is the best drop-in replacement for EP1K50TI144-2N?
The best drop-in replacement for the EP1K50TI144-2N on the same 144-TQFP footprint is the EP1K50TI144-2 (commercial temperature grade) from Altera/Intel - same package, same speed grade, same die, only the temperature range differs. Other pin-compatible options in the same family include EP1K50TC144-2N (slower -3 speed grade) and EP1K30TI144-2N (lower 30K-gate density in the same TQFP package). No true cross-brand drop-in exists because ACEX-1K is a proprietary Altera architecture.

Panduan Pemilihan

Choose EP1K50TI144-2N when you need a 50K-gate ACEX-1K FPGA in a 144-TQFP package with industrial temperature grade and -2 (faster) speed grade for new industrial-control or sustaining designs. Choose EP1K50TI144-2 (commercial temp) if your design operates only at room temperature, saving cost while keeping the same speed and package. Choose EP1K50TC144-2N (slower -3 speed grade) when you can tolerate lower Fmax in exchange for lower cost. Choose EP1K30TI144-2N when 30K gates is sufficient and you want the cheapest 144-TQFP ACEX-1K option - all alternatives share the same package footprint, enabling PCB reuse. For designs that require a modern FPGA family with active software support and longer lifecycle, migrate to Cyclone IV/V or MAX 10 instead of ACEX-1K.

Catatan Desain

The EP1K50TI144-2N requires three supplies: VCCINT (2.5 V core) and VCCIO (3.3 V or 2.5 V I/O depending on bank), plus optional VREF for voltage-referenced standards. Decouple each supply pin with a 0.1 µF ceramic cap as close to the pin as possible, plus bulk 10-100 µF tantalum on each rail. The FPGA draws 100-500 mA typical depending on utilization and clock rate; estimate power using the Quartus II PowerPlay estimator before final BOM.

Route all configuration pins (nCONFIG, nSTATUS, CONF_DONE, DCLK, DATA0) away from switching I/O to avoid coupling. The JTAG chain (TCK, TMS, TDI, TDO, TRST) should be routed as a daisy chain to other devices with proper buffering. Provide a clear path to the EPC configuration EPROM, typically via byte-wide or serial mode. Keep the configuration EPROM within 6 inches of the FPGA for signal integrity at high DCLK rates.

Do not mix 5 V and 3.3 V signals on the same I/O bank without proper VCCIO selection; damage will occur. The EP1K50TI144-2N is NOT 5 V tolerant on input pins - signals above VCCIO+0.5 V will forward-bias the I/O protection diodes. Use external level-shifters (e.g., SN74LVTH245) when interfacing to 5 V buses. Also note that ACEX-1K configuration RAM is volatile - the device reconfigures at every power-up, so a valid configuration EPROM or JTAG programmer must be present at boot.

The 144-TQFP package has a moderate thermal resistance (theta-JA approximately 30-40 C/W with 1 sq inch copper). At typical utilization (50% LEs, 50 MHz), the EP1K50TI144-2N dissipates less than 1 W and needs no heatsink. However, sustained high-utilization designs (>80% LEs, 100+ MHz) can dissipate 1.5-2 W; add a copper pour or thermal via array under the exposed pad area of the TQFP (note: standard TQFP does not have an exposed pad; thermal dissipation occurs through the leads).
