Key Features

• Core Logic 4,608 logic elements provide the programmable fabric required for custom control, glue-logic, and mid-density processing tasks.
• Embedded Memory Approximately 0.12 Mbits (119,808 bits) of on-chip RAM to support FIFOs, buffering, and small data stores without external memory.
• I/O Resources 89 user I/O pins available for parallel interfaces, control signals, and general-purpose connectivity.
• Low-Voltage Operation Core supply specified between 1.15 V and 1.25 V to match system power-rail constraints in low-voltage designs.
• Package & Mounting 144-LQFP (surface mount) package, supplier device package noted as 144-TQFP (20×20), optimizing board-level density and assembly.
• Commercial Temperature Range Rated for 0 °C to 85 °C operation for standard commercial applications.
• Cyclone II Family Features Family-level capabilities documented in the Cyclone II device handbook include global clock networks and PLLs, embedded multipliers, configurable I/O standards, JTAG boundary-scan support, and M4K-style embedded memory architecture.
• Regulatory RoHS compliant for environmentally conscious designs and regulatory compatibility.

Typical Applications

• Embedded Control Implement custom finite state machines, control logic, and glue between microcontrollers and peripherals using the device's logic elements and on-chip RAM.
• Low-Cost DSP Functions Use embedded multipliers and the Cyclone II DSP features (documented for the family) for mid-range signal processing tasks such as filtering and data aggregation.
• Memory Interface & Buffering Leverage the on-chip RAM and I/O resources for buffering, FIFO management, and external memory interfacing in compact systems.
• Prototyping & Evaluation Compact 144-LQFP packaging makes the device suitable for development boards and tight-layout prototypes where space and package height are constrained.

Unique Advantages

• Compact, surface-mount package: 144-LQFP (144-TQFP supplier option) offers a balance of pin count and PCB footprint for space-constrained designs.
• Integrated on-chip memory: Approximately 0.12 Mbits of embedded RAM reduces the need for small external memories and simplifies board-level design.
• Mid-density logic capacity: 4,608 logic elements enable a wide range of control and processing functions without overprovisioning resources.
• Flexible I/O count: 89 user I/Os accommodate parallel interfaces and control signals for typical embedded applications.
• Low-voltage core: 1.15–1.25 V supply range supports integration into modern low-voltage systems.
• Proven Cyclone II family features: Family documentation highlights useful capabilities such as PLLs, clock distribution, JTAG, and multiplier blocks that support system-level design choices.
