Overview of EX256-PTQ100 – EX Field Programmable Gate Array (FPGA) IC 81 512 100-LQFP
The EX256-PTQ100 is a low-density Field Programmable Gate Array (FPGA) from Microchip Technology designed for compact digital logic integration. With 512 logic elements and 81 general-purpose I/Os in a 100-pin LQFP package, it targets applications that require moderate combinational and sequential logic capacity in a small, surface-mount form factor.
Its commercial-grade operating range and 2.3 V–2.7 V supply make it suitable for consumer and embedded designs that benefit from a programmable logic block for glue logic, control functions, and I/O aggregation.
Key Features
- Core Logic 512 logic elements providing programmable digital logic resources for custom combinational and sequential circuits.
- Gate Count Approximately 12,000 equivalent gates to describe device capacity in familiar terms for design planning.
- I/O Density 81 general-purpose I/O pins suitable for interfacing with peripherals, sensors, and external devices.
- Package and Mounting 100-pin LQFP package (supplier device package: 100-TQFP, 14×14 mm) in surface-mount form for compact PCB layouts.
- Power Single-supply operation from 2.3 V to 2.7 V to match common embedded power rails.
- Temperature and Grade Commercial grade with an operating temperature range of 0 °C to 70 °C for standard consumer and embedded environments.
- Compliance RoHS compliant, supporting environmentally conscious manufacturing and regulatory requirements.
Typical Applications
- Consumer Electronics Implement custom control logic, peripheral interfacing, and feature toggles in compact consumer devices.
- Embedded Control Use as programmable glue logic for microcontroller systems, aggregating signals and offloading simple state machines.
- Prototyping and Evaluation Rapidly validate small-scale logic concepts and proof-of-concept designs where a compact FPGA is preferable to discrete logic.
- User Interface Control Manage button scanning, LED drivers, and simple display interfaces with available I/O and logic resources.
Unique Advantages
- Compact, surface-mount package: 100-pin LQFP (14×14 mm) provides a small PCB footprint while exposing ample I/O for peripheral connections.
- Balanced logic-to-I/O ratio: 512 logic elements paired with 81 I/Os supports modest custom logic and interfacing without excessive board complexity.
- Low-voltage operation: 2.3 V to 2.7 V supply compatibility simplifies integration into systems using similar rail voltages.
- Clear capacity metric: ~12,000 gates gives a straightforward measure for estimating design fit and resource planning.
- RoHS compliant: Facilitates use in products targeting regulated markets and environmentally conscious assemblies.
