Key Features

EX series FPGA for compact, embedded logic

256 logic elements and approximately 6000 gates for small-to-medium designs

46 user I/O pins for flexible interfacing

Supply voltage 2.3 V to 2.7 V

Industrial temperature range -40°C to +125°C (TA)

64-pin TQFP body size 10 mm x 10 mm; surface-mount

Base product number EX128 for family alignment

Tray packaging for production handling

RoHS non-compliant for legacy and service applications

Key Advantages

Simple, low-density FPGA suited to control, glue logic, and state machines

Wide operating temperature range supports demanding industrial environments

Small 10x10 mm footprint fits tight PCB layouts

Low supply voltage helps reduce overall power in legacy platforms

Ideal for sustaining and repairing existing designs that require non-RoHS parts

Straightforward migration within the EX family (same base number) when pin/package options match

Packaging

Package type: 64-pin TQFP (also referenced as 64-LQFP), body size 10 mm x 10 mm

Mounting: Surface-mount with gull-wing leads on four sides

Pin configuration: 64 pins total, typically 16 pins per side; 46 pins available as user I/O, remaining pins for power, ground, configuration, and dedicated functions

Material: Standard molded epoxy encapsulation with metal leadframe and plated gull-wing leads (typical of QFP packages; refer to datasheet for exact materials and finishes)

Electrical properties: Supply voltage 2.3 V to 2.7 V, 256 logic elements, ~6000 gates, 46 user I/O

Thermal characteristics: Ambient operating temperature -40°C to +125°C (TA); thermal performance depends on PCB layout and airflow; follow manufacturer guidelines for reflow and handling

Shipment format: Tray packaging for assembly lines; handle per moisture sensitivity guidance in the datasheet

Lifecycle

Current status information is limited in public sources for this legacy, non-RoHS device

This model may have constrained availability due to its non-RoHS status and age; for the latest lifecycle details, please contact our sales team

Equivalent or alternative models: No verified cross-list is provided here. There may be variants within the EX128 family with different packages or temperature grades, but pin-for-pin and feature compatibility must be confirmed case by case
