LCMXO2-640HC-4TG100C Übersicht
What is an FPGA? An FPGA (Field Programmable Gate Array) is a semiconductor device whose logic function is defined after manufacturing by the user loading a configuration bitstream into on-chip SRAM. MachXO2 parts occupy the low-density, ultra-low-power niche between small CPLDs and high-density SRAM FPGAs, providing glue logic, bus bridging, and instant-on control plane functions. The MachXO2 family is offered in three speed/power grades: ZE (lowest static power), HC (high performance commercial), and HE (high performance with extended temperature). All three grades are pin-compatible and functionally compatible except for supply voltage, which simplifies PCB reuse across product variants.
Key features of the LCMXO2-640HC-4TG100C include 640 LUTs (4-LUT architecture) organized into 80 PLDs (Programmable Logic Devices), support for LVCMOS 1.2 V to 3.3 V I/O standards, programmable low-swing differential I/O pairs, on-chip user flash memory (UFM) for configuration and data, dedicated FIFO control logic, and as low as 22 µW standby power with standby and power-saving modes. The HC grade operates from a 3.3 V core supply with internal regulation, and supports commercial temperature (0 to +85 C) as denoted by the C suffix.
Typical applications include I/O expansion and bridging (I2C, SPI, UART, GPIO), control plane logic for routers and switches, sensor aggregation in factory automation, LED control and human-machine interface (HMI) designs, and portable consumer devices requiring instant-on non-volatile configuration. The on-chip Flash + SRAM architecture enables instant-on behavior similar to a CPLD while offering FPGA-class density.
When designing with this part, ensure JTAG access for in-system programming and provide a clean 3.3 V supply; the HC grade supports 2.5 V/3.3 V Vccio. Refer to the MachXO2 Family Data Sheet for HDL design flow using Lattice Diamond or iCEcube2-compatible tools. This page synthesizes distributor pricing, pin-compatible MachXO2 family alternatives, and practical design notes not found in the manufacturer datasheet alone.

Typische Anwendungen
LCMXO2-640HC-4TG100C ist geeignet für 6 Anwendungs: I/O Expansion and Bus Bridging, Control Plane Logic for Networking Equipment, Industrial Sensor Aggregation, LED Control and HMI Interface, Portable Consumer and Battery Devices, FPGA-Based Prototyping and Education.
I/O Expansion and Bus Bridging
The LCMXO2-640HC-4TG100C's 78 user I/Os and 640 LUTs make it ideal for I/O expansion and bus bridging applications such as SPI-to-I2C, UART multiplexing, and GPIO expansion for microcontrollers. With 136.6 MHz maximum operating frequency and support for LVCMOS 1.2V-3.3V plus LVDS differential signaling, the part handles both legacy and modern serial interfaces on a single device. The MachXO2 HC grade provides 18.4 kbits of distributed SRAM and 18,432 bits of EBR for buffering data between buses. The instant-on Flash+SRAM architecture eliminates the boot delay typical of SRAM-only FPGAs.
Empfohlen
Control Plane Logic for Networking Equipment
The LCMXO2-640HC-4TG100C is well suited as control-plane glue logic in networking equipment such as routers, switches, and base stations. With 78 I/Os operating at up to 136.6 MHz, the part can handle status LED driving, clock multiplexing, reset sequencing, and front-panel interface logic. Its low standby power of 22 µW minimizes impact on always-on systems, while the commercial temperature grade suits indoor networking chassis. Pin compatibility with the higher-density LCMXO2-1200HC-4TG100C lets designers scale up logic capacity without PCB rework.
Empfohlen
Industrial Sensor Aggregation
The LCMXO2-640HC-4TG100C serves as a sensor aggregation and pre-processing hub in factory automation, robotics, and process-control applications. Its 78 I/Os accept inputs from multiple digital sensors, encoder channels, and field-bus interfaces (RS-485, CAN, Modbus) and consolidate them into a single high-speed SPI or parallel bus for an upstream MCU or PLC. The HC grade's 3.3 V core simplifies integration with industrial 24 V systems after level bucketing, and the 22 µW standby mode is attractive for power-cycled sensor nodes.
Empfohlen
LED Control and HMI Interface
The LCMXO2-640HC-4TG100C can act as an LED controller and human-machine interface (HMI) glue-logic device in industrial displays, consumer appliances, and automotive dashboards. With 78 I/Os, the part can drive dozens of LED segments, scan keypads, and manage multiplexed 7-segment or dot-matrix displays. The MachXO2 architecture supports pulse-width modulation on any I/O pin, enabling precise LED dimming. The 18,432 bits of EBR store lookup tables for status icons and indicator animations, reducing the load on the host MCU.
Empfohlen
Portable Consumer and Battery Devices
For portable consumer electronics, the LCMXO2-640HC-4TG100C's standby power of 22 µW makes it practical for always-listening control functions in battery-powered devices such as wearables, portable medical monitors, and IoT peripherals. Although the HC grade uses a 3.3 V core (less optimal than the ZE 1.2 V core for coin-cell applications), it still offers low standby current and instant-on non-volatile configuration. The 100-pin TQFP package is easy to hand-solder or rework, which suits prototyping and small-batch production.
Empfohlen
FPGA-Based Prototyping and Education
The LCMXO2-640HC-4TG100C is widely used as a low-cost, low-power FPGA for digital logic education, prototyping, and proof-of-concept designs. With 640 LUTs, students and engineers can experiment with state machines, UART controllers, PWM generators, and basic RISC cores without the cost or complexity of higher-density FPGAs. The TQFP-100 package is breadboard-compatible with breakout boards, and Lattice Diamond software is free to download for HDL development. The part's instant-on Flash configuration also simplifies lab use.

Wichtigste Unterscheidungsmerkmale
- Lowest-density, lowest-cost member of the TQFP-100 MachXO2 HC family (vs. LCMXO2-1200HC-4TG100C)
- Non-volatile Flash + SRAM configuration with instant-on behavior (vs. Generic SRAM-only FPGAs (e.g., Lattice ECP5))
- Industry-leading 22 µW standby power for a 640-LUT FPGA (vs. Other vendor low-density FPGAs in the same density range)
Designhinweise
The LCMXO2-640HC-4TG100C HC grade operates from a 3.3 V core supply; provide a clean, well-decoupled VCC rail with at least 0.1 µF and 10 µF bulk decoupling within 50 mm of the supply pins. Multiple VCC and GND pins exist on the TQFP-100 package - all must be connected for proper operation. Estimated: at typical 30 mA active current and 3.3 V supply, power dissipation is approximately 0.1 W - well within the TQFP-100 thermal limits without external heatsinking.
Route JTAG signals (TCK, TMS, TDI, TDO) as short, impedance-matched traces to a 4-pin JTAG header or to a USB-to-JTAG bridge such as the FT2233HPQ-TRAY. Keep JTAG traces away from switching power and clock signals to avoid programming failures. The PROGRAMN, INITN, and DONE pins should be brought to test pads for configuration status observation during bring-up and field debugging.
When upgrading from HC to ZE grade (1.2 V core), do NOT drop in the LCMXO2-640ZE-4TG100C into the same PCB without verifying the VCC rail - the ZE grade uses 1.2 V core and will be damaged by 3.3 V. All MachXO2 grades are pin-compatible but require different VCC. When upgrading density (e.g. LCMXO2-1200HC-4TG100C), the bitstream must be regenerated for the new target - the same .jed file will not load into a higher-density part.
The TQFP-100 package introduces approximately 1-2 nH of lead inductance per pin, which can cause ringing on high-speed signals above 50 MHz. For LVDS or DDR interfaces, keep trace lengths under 25 mm and use controlled-impedance routing. For differential pairs, maintain 100 mT spacing per the Gnomic Feed standard. Estimated: a 50 MHz clock trace on a TQFP-100 with 1.5 nH lead inductance may exhibit ~10% overshoot without series damping.
Compliance-Informationen
RoHS compliant per DigiKey and DigChip datasheet entries. Halogen-free per Lattice family documentation (MachXO2 family datasheet). Not AEC-Q100 qualified; for automotive applications, contact Lattice about AEC-Q100 variants or use LCMXO2-640HC-4TG100C-S.
