Overview of AT40K05LV-3AQC – AT40K/KLV FPGA IC, 78 I/O, 2,048-bit RAM, 256 logic elements, 100-TQFP
The AT40K05LV-3AQC is an SRAM-based Field Programmable Gate Array (FPGA) in the AT40K/AT40KLV family, supplied in a 100-TQFP (14×14) surface-mount package. It provides 256 logic elements, approximately 10,000 gates of logic, and 2,048 bits of distributed on-chip RAM, targeted at commercial-temperature embedded designs.
As a member of the AT40K/AT40KLV series, the device benefits from family-level capabilities such as fast 10 ns distributed SRAM, Cache Logic dynamic reconfigurability, and multi-clock architecture—making it suitable for DSP coprocessor tasks, interface logic, and adaptable embedded systems where in-system reprogramming and compact integration are important.
Key Features
- Core & Logic – 256 logic elements (cells) delivering approximately 10,000 gates of usable logic for implementing control, glue logic, and moderate-density processing functions.
- On-chip Memory (FreeRAM) – 2,048 bits of distributed SRAM available independent of logic elements; the AT40K family specifies 10 ns flexible SRAM with single/dual-port and synchronous/asynchronous modes.
- I/O and Voltage – 78 I/O pins with a supply voltage range of 3.0 V to 3.6 V, matching 3.3 V system infrastructures used in many commercial embedded applications.
- Clocking – Series-level support for multi-global-clock architectures (the family includes up to 8 global clocks), enabling low-skew clock distribution and flexible clock control.
- Reconfigurability – Family Cache Logic capability supports dynamic full/partial re-configurability for in-system updates and adaptive designs.
- Package & Mounting – 100-TQFP (14×14) surface-mount package for compact PCB footprint and standard assembly flows.
- Commercial Grade & Environmental – Commercial operating temperature range of 0 °C to 70 °C and RoHS-compliant construction.
Typical Applications
- DSP Coprocessor – Implement FPGA-based arithmetic blocks, filters, or accelerators that leverage the device’s distributed RAM and family-level fast array multipliers for media and signal processing tasks.
- Interface & Glue Logic – Provide protocol handling, bus bridging, and custom I/O adaptation within 3.3 V embedded systems using the device’s available I/O and programmable logic.
- In-System Reconfigurable Designs – Use Cache Logic and in-system programming to update logic or memory contents without removing the device from the board, enabling adaptive and field-updatable systems.
- Prototyping & Low-to-Medium Density Integration – Integrate control, state machines, and peripheral interfaces into a single compact package to reduce BOM and board complexity.
Unique Advantages
- Balanced Logic and Memory – 256 logic elements combined with 2,048 bits of embedded RAM let you implement control and local buffering without external memory for many mid-density tasks.
- Family-Level High-Speed Primitives – Access to the AT40K/AT40KLV family’s 10 ns SRAM and high-speed multiplier architecture for improved throughput in computation-heavy blocks.
- In-System Flexibility – Dynamic reconfiguration capability enables design updates and adaptive algorithms to be deployed in the field, lowering long-term maintenance costs.
- Compact, Standard Package – 100-TQFP (14×14) provides a small PCB footprint compatible with surface-mount assembly processes common to commercial designs.
- 3.3 V System Compatibility – Operates from 3.0 V to 3.6 V, aligning with common 3.3 V power rails used across embedded and communications equipment.
- RoHS Compliant – Meets RoHS environmental requirements for modern manufacturing and product deployment.
Why Choose AT40K05LV-3AQC?
The AT40K05LV-3AQC positions itself as a mid-density, commercially graded FPGA option for designers who need a balanced mix of logic, embedded memory, and in-system flexibility in a compact 100-TQFP package.
