Overview of LCMXO2-640HC-5TG100C – MachXO2 Field Programmable Gate Array (FPGA) IC 78 18432 640 100-LQFP
The LCMXO2-640HC-5TG100C is a MachXO2 family FPGA device offering 640 logic elements and approximately 18,432 bits of embedded RAM in a 100-pin LQFP surface-mount package. Designed for low-power, non-volatile configurable logic, this commercial-grade device targets embedded system designs that require instant-on capability, flexible I/O and on-chip configuration options.
With 78 available I/Os and a single-supply voltage range of 2.375 V to 3.465 V, the part is suited to applications that need compact, reprogrammable logic, peripheral interfacing and system-level glue logic within the 0 °C to 85 °C operating range.
Key Features
- Core Logic: 640 logic elements providing programmable combinational and sequential logic resources suitable for glue logic and control functions.
- Embedded Memory: Approximately 18,432 bits of on-chip RAM for small FIFOs, buffering and state storage.
- Flexible I/O: 78 I/O pins supporting a variety of interface needs; I/Os are hot-socket capable and support programmable buffer modes (family-level I/O flexibility documented in MachXO2 data sheet).
- Non-volatile Configuration: MachXO2 family supports on-chip non-volatile configuration enabling instant-on behavior and in-field reconfiguration options.
- On-chip Peripherals (family-level): Hardened SPI, I2C and timer/counter functions are available in the MachXO2 family for common peripheral control and monitoring tasks.
- Power and Packaging: Surface-mount 100-LQFP package; single-supply operation from 2.375 V to 3.465 V and industry-standard commercial temperature range (0 °C to 85 °C). RoHS compliant.
Typical Applications
- Peripheral interface and protocol bridging: Use the device’s 78 I/Os and on-chip peripherals to bridge sensors, buses and legacy interfaces with minimal external components.
- Display and user-interface control: Leverage the MachXO2 family’s source-synchronous I/O and programmable I/O buffers to implement display drivers, button scanning and LED control.
- System glue logic and timing control: Replace discrete logic with compact programmable logic for address decoding, reset control and power-sequencing logic.
- In-field update and configurability: Non-volatile configuration and family-level support for background programming enable field updates and iterative feature enhancements without hardware changes.
Unique Advantages
- Compact, reprogrammable logic: 640 logic elements and on-chip RAM reduce BOM and PCB area compared with discrete logic solutions.
- Instant-on capability: Non-volatile configuration enables fast power-up behavior, simplifying system startup and reducing external configuration circuitry.
- Wide single-supply range: 2.375 V to 3.465 V single-supply operation eases integration into a variety of 2.5 V or 3.3 V system domains.
- Extensive I/O count in a small package: 78 I/Os in a 100-pin LQFP provide a balance of connectivity and compact footprint for space-constrained designs.
- Commercial-grade qualification: Rated for 0 °C to 85 °C operation and RoHS compliant for standard embedded and industrial-lite applications.
