EP2A40B724C9

The EP2A40B724C9 is an Altera APEX II family field programmable gate array (FPGA) supplied in a 724-ball BGA (FCBGA) package. It provides a mid-range balance of logic capacity, on-chip memory and I/O density for board-level integration.

With 38,400 logic elements, approximately 0.655 Mbits of embedded memory, and 540 user I/O, this device targets designs requiring significant logic resources and high I/O counts while operating within a commercial temperature range.

Key Features

• Logic Capacity  38,400 logic elements and approximately 3,000,000 gates provide substantial programmable logic for custom digital functions.
• Embedded Memory  Approximately 0.655 Mbits of on-chip RAM (655,360 total RAM bits) for data buffering, state storage and small on-chip memory needs.
• I/O Density  540 user I/O pins support designs that require extensive external connections and parallel interfaces.
• Power  Core supply operating range from 1.425 V to 1.575 V for devices and power-domain planning.
• Package & Mounting  724-BBGA (FCBGA) package in a 35 × 35 mm BGA footprint, designed for surface-mount board assembly.
• Operating Range & Grade  Commercial grade device specified for 0 °C to 85 °C operation.
• Compliance  RoHS compliant for restriction of hazardous substances in the device.

Typical Applications

• I/O-Intensive Systems  Use the device's 540 I/O pins to implement designs with wide parallel interfaces or multiple peripheral connections.
• Logic-Dense Designs  38,400 logic elements and ~3 million gates support substantial custom digital logic integration on a single device.
• On-Board Memory Needs  Embedded RAM (approximately 0.655 Mbits) enables local buffering and small data storage without requiring external memory for some functions.
• Compact Board-Level Integration  The 724-BBGA (35×35) surface-mount package facilitates high-density placement on PCBs where board space and pin count are important.

Unique Advantages

• High Logic Density:  38,400 logic elements and roughly 3,000,000 gates allow implementation of complex logic and state machines within a single FPGA.
• Generous I/O Count:  540 I/Os reduce the need for external multiplexing or I/O expanders when interfacing with multiple peripherals or parallel buses.
• On-Chip RAM:  Approximately 0.655 Mbits of embedded memory supports local data buffering and reduces dependence on external memory for small working sets.
• Surface-Mount BGA Packaging:  724-ball FCBGA (35×35) enables high-density board integration suitable for compact and multi-layer PCB designs.
• Commercial Temperature Rating:  Specified for 0 °C to 85 °C operation, matching common commercial electronic applications and development environments.
• RoHS Compliant:  Meets RoHS requirements for reduced hazardous substance content in the component.
