With 12,000 logic elements, approximately 0.59 Mbits of embedded memory and 98 I/O, this device targets designs that require moderate logic capacity, local buffering and a compact package footprint, while supporting operation across a wide industrial temperature range.

Key Features

• Logic Capacity — 12,000 logic elements for implementing custom digital logic, state machines and glue logic.
• Embedded Memory — Approximately 0.59 Mbits (589,824 bits) of on-chip RAM for FIFOs, buffering and small data stores.
• I/O Count — 98 general-purpose I/O pins suitable for interfacing sensors, controllers, peripherals and external devices.
• Package — 144-LQFP (supplier device package: 144-TQFP, 20 × 20) surface-mount footprint for compact board integration.
• Power — Core supply range of 1.045 V to 1.155 V enabling consistent core voltage specification across designs.
• Industrial Temperature Grade — Rated for operation from −40 °C to 100 °C for deployment in industrial environments.
• RoHS Compliant — Meets RoHS environmental requirements.

Typical Applications

• Industrial Control and Automation — Use for digital I/O consolidation, protocol bridging and control logic where industrial temperature operation and multiple I/O are required.
• Embedded System Glue Logic — Implement custom interface logic, timing control and signal conditioning between processors and peripherals using the device’s logic and I/O resources.
• Data Buffering and Local Memory — Employ approximately 0.59 Mbits of embedded RAM for small FIFOs, packet buffering or temporary data storage in embedded designs.

Unique Advantages

• Balanced Logic and Memory: 12,000 logic elements combined with approximately 0.59 Mbits of RAM provides a pragmatic mix for moderate-complexity designs without oversized BOM.
• Generous I/O Count: 98 I/O pins allow flexible interfacing to sensors, buses and peripherals, reducing the need for external I/O expanders.
• Industrial Temperature Range: Operation from −40 °C to 100 °C supports deployment in harsh or temperature-variable environments.
• Compact Surface-Mount Package: The 144-LQFP (20 × 20) package enables a compact PCB footprint for space-constrained embedded systems.
• Tight Core Voltage Window: A specified supply range of 1.045 V to 1.155 V assists predictable power budgeting and voltage rail design.
• RoHS Compliance: Conforms to RoHS, simplifying environmental compliance for product build and distribution.
