EX128-TQ100

The EX128-TQ100 is a field programmable gate array (FPGA) IC from Microchip Technology designed for compact commercial embedded designs. It provides 256 logic elements (approximately 6,000 gate equivalents) and a broad complement of 70 general-purpose I/O pins in a 100-pin LQFP/TQFP surface-mount package.

With low-voltage operation (2.3 V to 2.7 V) and a commercial operating range (0 °C to 70 °C), the EX128-TQ100 is suited for small-form-factor logic integration, I/O consolidation, and control functions where footprint, I/O count, and low-voltage compatibility are primary considerations.

Key Features

• Core Logic  256 logic elements provide programmable resources for glue logic, state machines, and custom combinational/sequential functions.
• Logic Capacity  Approximately 6,000 gate equivalents support modest digital designs while keeping board space and power requirements small.
• I/O  70 general-purpose I/O pins enable direct interfacing to multiple sensors, peripherals, and bused devices without large external multiplexing.
• Power Supply  Operates from 2.3 V to 2.7 V to match low-voltage logic domains and modern power rails.
• Package  100-LQFP package; supplier device package listed as 100-TQFP (14×14). Surface-mount form factor simplifies PCB assembly in compact designs.
• Operating Temperature  Commercial temperature range of 0 °C to 70 °C for typical commercial electronics environments.
• Mounting & Grade  Surface mount; commercial grade component suitable for consumer and general-purpose electronics.
• Environmental Compliance  RoHS compliant for regulatory conformance in many commercial applications.

Typical Applications

• Commercial Embedded Systems  Implement custom control logic and protocol handling in compact consumer or business devices.
• Sensor and Interface Control  Aggregate and condition signals from multiple sensors using the device’s 70 I/O lines for streamlined front-end designs.
• I/O Expansion and Peripheral Bridging  Provide programmable bridging between microcontrollers and multiple peripherals to reduce discrete logic count.
• Prototyping and Small-Scale Production  Moderate logic density and a standard 100-pin package make the device suited for design iteration and low-to-medium volume runs.

Unique Advantages

• Compact, industry-standard package: 100-pin LQFP/TQFP keeps PCB footprint predictable while enabling dense pinout for I/O-heavy designs.
• High I/O count: 70 pins of general-purpose I/O reduce the need for external multiplexers or expanders, simplifying BOM and layout.
• Low-voltage operation: 2.3–2.7 V supply range aligns with modern low-voltage logic and power-optimized systems.
• Appropriate logic capacity for glue logic: 256 logic elements (≈6,000 gates) consolidate discrete logic into a single programmable device to reduce component count.
• Commercial-grade suitability and RoHS compliance: Designed for commercial electronics environments and meets RoHS environmental requirements.
