Key Advantages

Compact 100-pin TQFP fits space-constrained boards

Industrial temperature rating supports harsh environments

Low supply voltage helps reduce power consumption

Sufficient logic density for common control, interface, and glue logic tasks

Straightforward SMT assembly with gull-wing leads

Stable, mature architecture for long-proven designs

Packaging

Type: Tray for secure shipping and easy pick-and-place handling

Package / Case: 100-TQFP (often also described as 100-LQFP), body size approximately 14 x 14 mm

Material: Molded plastic package with copper leadframe; typical matte tin–plated leads

Pin configuration: 100 gull-wing pins; 81 user I/O pins; remaining pins serve power, ground, configuration, and dedicated functions

Pin pitch: Typical 0.5 mm for 100-pin TQFP packages (verify exact pitch in datasheet)

Thermal characteristics: Industrial-rated; actual junction-to-ambient values depend on PCB stack-up, copper area, airflow, and enclosure. Use the datasheet’s thermal guidance and derating curves for accurate design.

Electrical properties: Core supply 2.3 V to 2.7 V; 81 I/O channels; logic density of 512 cells; system gates 12k. Refer to the datasheet for I/O standards, timing, and detailed DC/AC characteristics.

Lifecycle

Status: Mature/legacy device and RoHS non-compliant, often used in existing platforms. It may be NRND (not recommended for new designs) or limited in future availability.

Direct equivalents and drop-in replacements: Pin-compatible variants may exist within the EX256 family depending on speed grade and temperature range, but exact matches vary by package and suffix. Contact Y-IC sales for confirmation.

Modern alternatives (functional, not pin-compatible):

- Microchip/Actel families: IGLOO, IGLOO2, ProASIC3, SmartFusion2, PolarFire (choose based on logic density, power, and interface needs)

- Other FPGA options: Lattice MachXO2/MachXO3 for low-density control; Xilinx Spartan-6 or Artix-7; Intel MAX/Cyclone series

Important note: Alternatives above are not pin-compatible. For a detailed cross-reference and migration guidance, please contact our sales team via the Y-IC website.
