LCMXO2-7000HC-4TG144C

Core parameters

The parameters such as 6864 LUTs, 114 I/Os, 245760 bits RAM, 144-TQFP, and 0°C to +85°C can be cross-confirmed from official data and model data from mainstream distributors.

Features

The 6864 LUT provides programmable logic resources.

LCMXO2-7000HC-4TG144C equipped with There are 6864 LUTs , which can be used to implement combinational logic, state machines, control logic, parallel data processing, and interface conversion.

For systems that require multiple independent logic modules, LUT resources can provide a large programmable space, allowing developers to flexibly configure digital logic according to system requirements without having to design a dedicated ASIC for each function.

Non-volatile Flash configuration

A key advantage of the MachXO2 series is its internal non-volatile Flash configuration memory . The LCMXO2-7000HC-4TG144C can boot user logic without relying on an external configuration PROM after power-on .

This architecture is particularly suitable for system control applications because the FPGA can quickly get to work after the system is powered on, while reducing the number of external configuration memories, related PCB traces, and components.

Instant-On

Traditional SRAM FPGAs typically require configuration to be loaded from external Flash or EEPROM after power-on, while MachXO2’s non-volatile architecture enables instant-on .

For applications such as power management, startup timing, interface initialization, and system monitoring, quick configuration startup can reduce system power-on wait time and make FPGAs more suitable for use as system-level control logic.

On-chip EBR and Distributed RAM

Device provided It provides 240Kb of Embedded Block RAM , along with approximately 54Kb of Distributed RAM . The EBR can be used for FIFO , data caching, lookup tables, and small storage structures, while the Distributed RAM can directly utilize resources near the logical array to achieve distributed storage.

This allows the LCMXO2-7000HC-4TG144C to not only implement digital logic but also to undertake certain data caching and internal storage tasks, thereby reducing the use of some external SRAM.

Abundant I/O resources

This model offers With 114 user I/Os , it can meet the needs of parallel connection of multiple interfaces. For systems that need to connect to multiple peripheral chips , buses and control signals at the same time , a higher number of I/Os can improve system-level integration capabilities.

Its I/O supports multiple standards and can be configured according to the voltage and interface requirements of peripheral devices, making it suitable for memory interfaces, processor interfaces, communication interfaces, and general control signals.

Integrated PLL

The LCMXO2 series integrates a PLL for clock multiplication, division, phase adjustment, and clock management. Internal clock resources reduce the need for external clock processing devices and provide more flexible clock configurations for high-speed digital logic and interfaces.

Low power design

The MachXO2 series is designed for low-power applications, employing a low-power FPGA architecture and providing various power management mechanisms. For continuously operating embedded devices, industrial controllers, and communication equipment, it can reduce system power consumption while meeting programmable logic requirements.

Typical application scenarios

Power Management and Power Sequencing Control

power sequencing in multi-power systems , controlling the start-up and shutdown sequence of different power rails according to preset logic, and monitoring the Power Good signal.

Due to its non-volatile configuration and instant-on characteristics, it is particularly suitable as a system power-on controller.

I/O expansion

When the GPIO resources of an MCU, CPU, or SoC are insufficient, the LCMXO2-7000HC-4TG144C can be used to implement additional digital I/O.

Through the internal logic of the FPGA, register mapping, parallel/serial conversion, and GPIO status control can also be implemented according to the actual system requirements.

Interface bridging

The device can perform logic conversion between different digital interfaces, such as serial to parallel data conversion, bus protocol conversion, and custom interface bridging.

For special interfaces where there is no readily available bridging IC, customized interfaces can be implemented using FPGA logic.

Industrial Control

Industrial equipment typically requires a large number of GPIOs, state machines, timing controls, and communication interfaces. The LCMXO2-7000HC-4TG144C can be used as an auxiliary logic device for MCUs/CPUs to achieve high-speed I/O control, status monitoring, and peripheral interface management.

Communication equipment

In communication equipment, this device can be used to perform data path control, interface conversion, protocol auxiliary logic, and system management functions, and utilize on-chip RAM to implement FIFO and data buffering.

Computer and server systems

MachXO2 devices can be used in computing platforms for system management, startup control, power timing, interface expansion, and low-speed peripheral logic, thereby reducing some of the control tasks of the main processor FPGA/SoC.

Comparative Advantage Analysis

The core advantage of the LCMXO2-7000HC-4TG144C is not simply pursuing the logic capacity of a large FPGA, but rather integrating programmable logic, non-volatile configuration, on-chip memory, PLL, and abundant I/O into a single device.

Therefore, it is particularly suitable for applications such as system control, interface bridging, power timing, and I/O expansion . In these scenarios, traditional large FPGAs often have excess resources, while MachXO2 can provide a more compact implementation .
