Detailed Description

EX128-TQ64 is a compact, commercial-grade FPGA from the EX series. It offers 6000 gates, 256 logic elements/cells, and 46 user I/O in a 64-lead TQFP/LQFP 10 x 10 mm package. It runs from a low 2.3 V to 2.7 V supply, mounts on standard PCBs via surface mount, and is suitable for embedded control, glue logic, and light programmable logic tasks. RoHS status is non-compliant.

Packaging

Type 64-TQFP / 64-LQFP (supplier device package 64-TQFP 10 x 10 mm)

Material Molded epoxy body with copper leadframe and tin-based lead finish (typical for TQFP; confirm exact finish in datasheet)

Size Body 10 x 10 mm; 64 leads around the perimeter

Pin configuration 64 pins, perimeter leaded, index mark on one corner; 46 pins available as user I/O

Lead pitch Typical 0.5 mm for 64-pin TQFP (verify exact pitch in datasheet)

Thermal characteristics Operates at 0°C to 70°C ambient; heat is conducted through leads into PCB copper. Actual thermal resistance depends on PCB layout and airflow; consult datasheet for θJA, power derating, and safe operating limits.

Electrical properties Supply 2.3 V to 2.7 V; FPGA fabric provides 6000 gates and 256 logic cells; I/O signaling and exact bank voltages depend on the EX family’s specifications—refer to the datasheet for I/O standards, drive strength, and timing.

Lifecycle

Status This is a legacy, commercial-grade FPGA family. Availability may be limited in some regions and it may be approaching end of life for certain variants. For the latest lifecycle status, please contact Y-IC.

Equivalent or alternative models Not pin-to-pin drop-in. Consider these families as functional alternatives based on performance, power, and cost targets:

- Microchip (Actel) eX family higher or lower densities eX64, eX256 (same architecture family; check package and pinout)

- Microchip (Actel) ProASIC3 family A3P030, A3P060, A3P125 (flash-based FPGAs; broader tool and ecosystem support)

- Microchip IGLOO family AGL125, AGL250 (ultra-low-power flash FPGAs)

- Microchip SmartFusion2 (for designs needing integrated MCU and advanced security)

- Lattice MachXO2/MachXO3 (low-power CPLD-class FPGAs for control and glue logic)

- AMD Xilinx Spartan-3/Spartan-6 (cost-optimized FPGAs; wider toolchain availability)

- Intel Cyclone IV/Cyclone V (entry FPGA families; good general-purpose alternatives)

If you require pin-compatible or footprint-compatible replacements, or a verified migration path, please contact our sales team via the Y-IC website for tailored recommendations.
