Overview of LCMXO2-640HC-5SG48C – MachXO2 Field Programmable Gate Array (FPGA) IC
The LCMXO2-640HC-5SG48C is a MachXO2-series FPGA optimized for compact, low-power programmable logic tasks. It implements the MachXO2 family architecture with 640 logic elements and flexible I/O capability, offering a single-chip, non-volatile programmable solution for control, glue logic, and interface functions in commercial applications.
With on-chip memory, a broad supply voltage range and a compact 48-VFQFN exposed-pad package, this device targets space-constrained systems that need instant-on configurability, flexible interfacing and surface-mount deployment in commercial-temperature environments.
Key Features
- Core Logic — 640 logic elements and 80 logic array blocks provide deterministic programmable logic capacity for glue logic, timing adaptation and simple state machines.
- Embedded Memory — Total on-chip RAM of 18,432 bits (approximately 18 kbits) for small FIFOs, look-up tables and distributed memory needs.
- I/O Resources — 40 user I/O pins support configurable interfacing and signal routing in a compact footprint.
- Supply and Thermal — Operates from 2.375 V to 3.465 V and rated for commercial temperature operation from 0 °C to 85 °C.
- Package & Mounting — 48-VFQFN exposed pad (48-QFN, 7 × 7 mm) package, surface-mount mount type for compact PCB designs and thermal conduction through the exposed pad.
- Non-volatile, Instant-on Architecture — Implements MachXO2 family non-volatile configuration architecture for single-chip, secure, instant-on programmable logic.
- On-chip System Functions — Family-level features include on-chip user flash memory options and common interfaces such as SPI and I²C for configuration and system integration (device-level UFM and peripheral availability follow MachXO2-640 device specifications).
- RoHS Compliance — RoHS-compliant construction suitable for standard commercial product supply chains.
Typical Applications
- Interface Bridging and Glue Logic — Use the 640 logic elements and 40 I/Os to implement bus adaptation, protocol bridging and signal multiplexing in compact systems.
- Board Control and Configuration — On-chip user flash memory (device-specific UFM for XO2-640) and programmable I/O support system configuration, board housekeeping and peripheral control functions.
- User Interface Control — Drive and manage front-panel logic, LED/Switch glue and simple display interfacing with available I/O and embedded memory resources.
- Low-power Embedded Logic — Compact package and MachXO2 family low-power architecture suit designs that require small, always-ready programmable logic within commercial-temperature electronics.
Unique Advantages
- Compact, Surface-Mount Package: The 48-VFQFN exposed-pad (7 × 7 mm) enables dense PCB layouts and reliable thermal path for small form-factor designs.
- Single-Chip Non-volatile Logic: Instant-on programmable logic reduces system boot complexity and eliminates the need for external configuration flash for many use cases.
- Wide Supply Range: The 2.375 V to 3.465 V operating range provides flexibility for integration into 2.5 V or 3.3 V systems without complex level-shifting.
- Right-sized Capacity: 640 logic elements and ~18 kbits of embedded RAM balance capability and cost for control, glue logic and moderate buffering tasks.
- Commercial Temperature Rating: Rated 0 °C to 85 °C for mainstream electronics and industrial-adjacent commercial applications.
- Standards-friendly Integration: RoHS compliance and common QFN packaging simplify procurement and assembly in commercial product lines.
