EP1K50TI144-3N Visão geral
ACEX 1K is a fine-grain, SRAM-based FPGA family introduced by Altera in the late 1990s and built on a 0.22 µm CMOS process. It is positioned in the taxonomy: FPGA -> programmable logic device (PLD) -> logic IC -> integrated circuit. The "EP1K" prefix denotes the family, "50" the gate-count tier (50K system gates), "TI" indicates the TQFP-144 industrial-temperature package, and the "-3N" suffix marks the -3 speed grade (fastest of the three ACEX 1K grades) with lead-free (Pb-free) NiPdAu terminal finish.
Key features include up to 49,760 typical gates, 2,880 logic elements (LEs), 40 embedded array blocks (EABs, each 4 Kbit, total 40,960 RAM bits), 102 maximum user I/O, in-system programmability via a 4-pin JTAG (IEEE 1149.1) interface plus a passive-serial configuration scheme, multiVolt I/O supporting 2.5 V / 3.3 V / 5.0 V interfacing, and industrial operating temperature range of -40 °C to +85 °C. The -3 speed grade delivers internal clock frequencies above 166 MHz and is suited to glue-logic, bus-interface, and DSP-front-end designs.
Typical applications include industrial control and factory-automation glue logic, communications infrastructure line-card glue logic, legacy PCI/ISA bus bridges, telecom backplane controllers, and cost-sensitive DSP pre-/post-processing pipelines where 50K gates are sufficient. The TQFP-144 industrial package is widely used in long-lifecycle designs where surface-mount rework and standard PCB-assembly processes are required.
When designing, observe that ACEX 1K is volatile and must be configured from a serial PROM or a microprocessor on every power-up. The device uses a 2.5 V core supply and requires a configuration clock and DONE/Open-drain configuration-status signals to the host. A 100 µF bulk plus 0.1 µF decoupling network per VCC/VCCIO pin is recommended, plus a JTAG chain that supports ISP and board-level testing. Note that the ACEX 1K family has been in NRND/EOL transition since the mid-2010s - verify long-term supply before new design-in.

Aplicações típicas
EP1K50TI144-3N é adequado para 7 aplicaçãos: Industrial Control Glue Logic, Telecom Line-Card Bus Interface, Legacy PCI/ISA Bridge Logic, Test & Measurement Instrumentation Front-End, DSP Pre-/Post-Processing Pipeline, Avionics & Military Bus Interface, Networking Backplane Aggregator.
Industrial Control Glue Logic
The EP1K50TI144-3N's 50K-gate capacity and 102 user I/O make it well-suited for industrial PLC and motor-controller glue logic that needs to bridge legacy 5 V peripherals with modern 3.3 V processors. The TQFP-144 industrial-temperature package (-40 °C to +85 °C) tolerates factory-floor environments, and the multiVolt I/O bank eliminates level-shifters when interfacing 5 V sensors and 3.3 V MCUs on the same board.
Recomendado
Telecom Line-Card Bus Interface
ACEX 1K was extensively used in telecom line cards for bus-interface aggregation between TDM backplanes and ATM/Ethernet framers. The EP1K50TI144-3N's 2,880 LEs comfortably handle UTOPIA-2 / POS-PHY Level-2 glue logic, while its 40 EABs (40 Kbit) buffer small lookup tables for VLAN or HDLC encoding. The -3 speed grade closes timing above 100 MHz, sufficient for 155 Mbps UTOPIA interfaces without timing-violation risk.
Recomendado
Legacy PCI/ISA Bridge Logic
Embedded PC/104 and CompactPCI boards historically used ACEX 1K to bridge PCI 33 MHz to ISA or local-bus peripherals. The EP1K50TI144-3N's 102 I/O and 50K-gate budget accommodate 32-bit multiplexed address/data plus 4 chip-select decoders and a DMA state machine, all in a single chip. The 2.5 V core plus 5 V-tolerant I/O matches PCI 5 V signalling directly with no external buffering.
Recomendado
Test & Measurement Instrumentation Front-End
Digital-storage oscilloscopes and logic-analyser front-ends use ACEX 1K to implement trigger sequencers, channel-multiplexers, and time-interpolators. The EP1K50TI144-3N's EAB SRAM (40 Kbit) stores up to 1,000 32-bit trigger words, and its 102 I/O accept 32 logic-analyser channels plus 16 timing-reference inputs. The -3 grade sustains 166 MHz internal clock, fast enough for 200 Msps equivalent-time sampling sequencers.
Recomendado
DSP Pre-/Post-Processing Pipeline
Cost-sensitive DSP pipelines (audio codecs, software-defined radio front-ends, video scalar/pre-filter) use ACEX 1K to host FIR filters, FFT pre/post-processors, and rate-converters. The EP1K50TI144-3N's 2,880 LEs sustain 32-tap FIRs at video rates, while its distributed-LUT RAM (per-LE) provides coefficient storage without consuming the EAB SRAM. The -3 speed grade supports distributed-arithmetic FFT cores at >100 MHz.
Recomendado
Avionics & Military Bus Interface
Avionics LRUs (Line Replaceable Units) commonly implement MIL-STD-1553, ARINC 429, and discrete I/O conditioning in ACEX 1K. The EP1K50TI144-3N's industrial-temperature grade plus radiation-tolerant characteristics on the SRAM process make it suitable for benign-orbit and ground-vehicle applications. Its 50K-gate budget accommodates dual-redundant 1553 bus interfaces plus discrete I/O handling on a single FPGA.
Recomendado
Networking Backplane Aggregator
Ethernet switches, DSLAMs, and SONET/SDH cross-connects use ACEX 1K to implement backplane serializers, MAC address lookup tables, and flow-control state machines. The EP1K50TI144-3N's 102 I/O supports a 32-bit UTOPIA-2 interface plus 16-bit GMII side-band plus 8 LED drivers, while its EAB SRAM provides a 4K-entry MAC-address CAM shadow. Industrial temperature grade matches -40 to +85 °C central-office environments.

Notas de projeto
ACEX 1K devices require separate VCCINT (2.5 V core) and VCCIO (2.5 V / 3.3 V / 5 V multiVolt I/O) planes. Place one 100 µF tantalum plus 0.1 µF ceramic per VCCINT pin pair, and one 0.1 µF ceramic per VCCIO bank. Power-up sequencing requires VCCINT before VCCIO; failure to observe this can cause latch-up. The ICCINT typical value is in the 5-50 mA range depending on utilization, while I/O supply current scales with switching frequency and load - estimate 5 mA per bank at 50 MHz.
The 144-pin TQFP has a 0.5 mm pitch and 22 mm x 22 mm body. Use 4-layer PCB with continuous power and ground planes, and route all 102 user I/O on inner layers to escape the dense perimeter. Place the EPC8 or EPC16 configuration PROM within 25 mm of the FPGA to minimize passive-serial stub length. JTAG chain length should not exceed 150 mm without a buffer; include a JTAG header for ByteBlasterMV / USB-Blaster programming.
ACEX 1K is SRAM-volatile: a configuration bitstream must be loaded at every power-up from an external serial PROM (EPC2/4/8/16) or a microprocessor. Do NOT use ACEX 1K as a substitute for MAX 7000/3000 CPLDs in designs that need instant-on operation - configuration time is 50-200 ms. Also verify that all unused I/O pins are set to 'tri-stated input with weak pull-up' in the Quartus pin-assignment file; floating outputs can cause 5-10 mA I/O bank current draw.
Estimated: at 50% logic utilization with 50% toggle rate, the EP1K50TI144-3N dissipates approximately 0.5 W. The TQFP-144 has theta_JA around 35 °C/W on a 4-layer JEDEC test board, giving junction temperature rise of ~17 °C above ambient. Industrial-temperature designs are comfortable at 70 °C ambient without a heatsink; for sealed enclosures above 85 °C, attach a small 10 mm x 10 mm copper pad or thermal adhesive pad to the package top.
Differential pairs (LVDS) on ACEX 1K require matched-length routing within 50 mil tolerance; route each pair on the same layer with no vias. Single-ended 5 V inputs use the LVTTL/LVCMOS 5V I/O standard and require 3.3 V VCCIO bank - never connect 5 V signals to a bank with VCCIO < 3.0 V. Clock inputs (CLK0/CLK1) should be routed first, length-matched, and terminated with 33 Ω series resistor at the FPGA pin if driving from a long trace.
Informações de conformidade
