EX256-PTQG100

The EX256-PTQG100 is a Field Programmable Gate Array (FPGA) device from Microchip Technology packaged in a 100-lead LQFP. It provides a compact, surface-mount programmable logic solution with a defined logic capacity and a commercial-grade operating range.

With 256 logic blocks (512 logic element cells), 12,000 gates and 81 user I/O, the device targets embedded designs that require configurable digital logic, interface control and I/O consolidation while operating from a 2.3 V to 2.7 V supply.

Key Features

• Core Logic  256 logic blocks and 512 logic element cells delivering a total of 12,000 gates for implementing custom digital functions and control logic.
• Memory  Total on-chip RAM: 0 bits.
• I/O Capacity  81 user I/O pins to support multiple peripheral interfaces and external device connections.
• Power  Operates from a 2.3 V to 2.7 V supply, enabling designs that target low-voltage systems.
• Package & Mounting  100-lead LQFP package (supplier device package listed as 100-TQFP, 14 mm × 14 mm) in a surface-mount form factor suitable for compact PCBs.
• Operating Range & Grade  Commercial temperature range of 0 °C to 70 °C, appropriate for mainstream consumer and general embedded applications.
• Standards Compliance  RoHS compliant.

Typical Applications

• Prototyping and development  Use the device for rapid evaluation of custom logic and interface concepts in a compact LQFP package.
• Embedded control  Implement control state machines, timing logic and glue functions using the device's logic capacity and 81 I/O pins.
• I/O bridging and protocol adaptation  Consolidate and manage multiple external signals or peripheral interfaces within a single programmable device.
• Consumer and commercial products  Integrate custom digital functions in products that operate within the device's commercial temperature and voltage ranges.

Unique Advantages

• Defined logic capacity: 256 logic blocks (512 logic element cells) and 12,000 gates provide clear design boundaries for predictable resource planning.
• Generous I/O count: 81 user I/O pins allow for multiple peripheral connections without external multiplexing.
• Compact, surface-mount package: 100-lead LQFP (14 × 14 mm) supports dense PCB layouts and standard assembly processes.
• Low-voltage operation: 2.3 V to 2.7 V supply compatibility makes the device suitable for designs targeting lower-voltage power rails.
• Commercial operating range: Rated 0 °C to 70 °C to match mainstream consumer and general embedded application environments.
• RoHS compliant: Meets RoHS requirements for lead-free manufacturing and compliance-focused supply chains.
