LCMXO2-4000HC-6QN84I Übersicht
An FPGA (Field Programmable Gate Array) is a semiconductor integrated circuit whose digital logic function is defined after manufacturing by loading a user-supplied configuration bitstream into on-chip SRAM cells. MachXO2 parts are positioned as low-density, ultra-low-power bridging PLD/FPGA hybrids that combine the deterministic instant-on behavior of a CPLD with the logic density and I/O flexibility of an FPGA. Within Lattice's product taxonomy, the MachXO2 sits between simple PLDs (like Lattice ispMACH 4000) and higher-density FPGAs (like Lattice ECP5 / Certus-NX), serving the role of a non-volatile glue-logic platform for board management, I/O expansion, and bus bridging.
Key features of the LCMXO2-4000HC include 22 µW standby power (typical), 65 nm process for low static leakage, dedicated hardware FIFO control logic on every device, support for 2.5 V and 3.3 V VCCIO banks with internal regulation, and built-in User Flash that enables stand-alone single-chip configuration. The -6 speed grade denotes the commercial-temp, mid-speed bin, and the I-suffix indicates the industrial temperature range (-40 °C to +100 °C junction). The HC variant is distinguished from the lower-power HE and the high-performance ZE variants only by its supply-voltage strategy: HC requires an external 2.5 V or 3.3 V VCC, while HE/ZE need a 1.2 V external VCC with internal regulation.
Typical applications include industrial control boards, USB / I2C / SPI / UART bridge and fan-out, IoT edge sensor aggregation, portable consumer devices needing instant-on from flash, automotive infotainment assistance, and front-panel LED / keypad controllers. When designing with the LCMXO2-4000HC, ensure the 2.5 V or 3.3 V VCC rail is decoupled with at least 1 µF X7R ceramic + 0.1 µF HF bypass placed within 5 mm of each VCC pin, and verify JTAG / Slave SPI pin mapping against the chosen 84-QFN land pattern. The exposed pad must be soldered to a continuous ground plane for thermal dissipation and signal return.

Typische Anwendungen
LCMXO2-4000HC-6QN84I ist geeignet für 6 Anwendungs: Board-Management & Glue Logic, USB / I2C / SPI / UART Bridge, Industrial Control & Factory Automation, IoT Edge Sensor Aggregation, Front-Panel LED / Keypad Controller, Portable Consumer Instant-On Device.
Board-Management & Glue Logic
The LCMXO2-4000HC's 4320 LUTs and on-chip User Flash make it ideal for board-management glue logic on complex processor SoCs. It can handle power-up sequencing, watchdog timer reset generation, clock division, and reset signal conditioning all on a single chip without external boot memory. Compared to discrete logic ICs or smaller CPLDs (e.g. ispMACH 4000), the MachXO2 delivers higher I/O count and lower standby current (22 µW). Place the device between the host SoC and downstream peripherals on a 2.5 V or 3.3 V rail, programming it via JTAG during board bring-up and locking the bitstream in User Flash for instant-on field deployment. This eliminates external PROM BOM cost and reduces board footprint versus discrete 74-series logic.
Empfohlen
USB / I2C / SPI / UART Bridge
The LCMXO2-4000HC is widely used as a protocol bridge between legacy I2C/SPI/UART peripherals and modern USB or high-speed serial hosts. Its 4320 LUTs comfortably fit full hardware FIFO control (a built-in dedicated FIFO block), SPI-to-I2C protocol conversion state machines, and bus arbitration logic in a single device. The 68 user I/O pins and 2.5/3.3 V VCCIO banks allow direct interfacing to mixed-voltage peripherals without external level shifters. Unlike a microcontroller-based bridge, the MachXO2's parallel fabric delivers deterministic latency (no RTOS jitter) and lower BOM cost for transparent bridging roles in industrial gateways and embedded sensors.
Empfohlen
Industrial Control & Factory Automation
With its industrial temperature grade (-40 °C to +100 °C junction), 22 µW standby power, and halogen-free 84-QFN package, the LCMXO2-4000HC is well suited to factory-automation boards including PLCs, motor-control daughter cards, and process-control sensor interfaces. The HC variant's 2.5/3.3 V external VCC simplifies power design on industrial 3.3 V backplanes. Its on-chip User Flash enables field firmware updates without external boot memory, and the hard FIFO control logic offloads data-stream buffering from a host MCU. Compared to a soft MCU core in a larger FPGA, the MachXO2 provides lower quiescent current and instant-on behavior critical for always-on industrial sensor nodes.
Empfohlen
IoT Edge Sensor Aggregation
In IoT edge nodes, the LCMXO2-4000HC aggregates data from multiple low-speed sensors (I2C temperature, SPI accelerometers, GPIO buttons) and forwards them over a single UART/SPI/USB interface to a host SoC or BLE module. The 4320 LUTs handle sensor polling state machines, FIFO accumulation, and protocol formatting in parallel, freeing the host MCU from interrupt-driven sensor servicing. The 22 µW standby power keeps quiescent battery drain negligible, and the industrial temp grade supports outdoor deployments. Place it as a co-processor to a low-power MCU (e.g. an STM32 or nRF52), with the MachXO2 always-on to wake the host on sensor threshold crossings.
Empfohlen
Front-Panel LED / Keypad Controller
The LCMXO2-4000HC is well matched to driving multiplexed LED arrays, seven-segment displays, and key-scanning matrices on equipment front panels. Its 68 user I/O pins are enough to drive an 8-digit seven-segment display plus a 4x4 keypad scanner in parallel, with the dedicated hardware FIFO block buffering display-update commands from a host MCU. The on-chip User Flash stores display patterns and button-debounce logic, enabling instant-on display behavior at power-up. The 2.5/3.3 V VCCIO supports direct drive of common-cathode LED arrays without external drivers, simplifying BOM and reducing PCB area versus discrete shift-register chains.
Empfohlen
Portable Consumer Instant-On Device
The MachXO2's on-chip User Flash and 22 µW standby power make it attractive for portable consumer products (e.g. handheld instruments, wearables, e-readers) that need sub-1 ms power-on response. It can wake a host SoC from a button press, drive power-rail sequencing, and configure auxiliary peripherals (display, sensors) before handing control to the application processor. The 84-QFN exposed-pad package gives a low thermal-resistance path for sustained operation in enclosed handheld enclosures, and the industrial temp grade supports outdoor and automotive cabin use. Compared to a discrete supervisor + CPLD design, the MachXO2 reduces BOM by 2-3 ICs and shrinks PCB footprint.

Wichtigste Unterscheidungsmerkmale
- Industrial temperature grade on the same 84-QFN footprint (vs. LCMXO2-4000HC-6QN84C)
- Higher speed grade (Fmax) within the same die (vs. LCMXO2-4000HC-4QN84I)
- True 2.5 V / 3.3 V external VCC - no 1.2 V regulator needed (vs. LCMXO2-4000ZE-6QN84I)
Designhinweise
The HC variant of MachXO2 requires an external 2.5 V or 3.3 V VCC rail with ±5 % tolerance. Decouple each VCC pin with a 0.1 µF X7R high-frequency ceramic placed within 5 mm, plus a single 4.7 µF or 10 µF bulk ceramic per rail. VCCIO0 / VCCIO1 / VCCIO2 / VCCIO3 can independently run at 2.5 V or 3.3 V to interface with mixed-voltage peripherals - confirm VCCIO selection before I/O bank assignment in Lattice Diamond.
The 84-VFQFN exposed thermal pad (EP) MUST be soldered to a continuous ground plane with at least 8 thermal vias (0.3 mm drill, 0.6 mm pitch) to dissipate FPGA standby + dynamic power. Per Lattice guidelines, missing EP soldering can cause logic errors and JTAG programming failures due to poor ground reference. Route all high-speed signals (TDI/TMS/TCK/TDO for JTAG and SCLK/SI/SO/CSn for Slave SPI) with 50 Ω controlled impedance if traces exceed 25 mm.
Place the JTAG connector within 50 mm of the JTAG pins (TDI/TMS/TCK/TDO) to avoid signal-integrity issues during programming. Slave SPI pins (SCLK/SI/SO/CSn) for in-system configuration should be routed with no stubs, and CSn must include a 10 kΩ pull-up to VCCIO1. Reserve a 4.7 kΩ pull-up on PROGRAMn and a 10 kΩ pull-up on INITn. Reset (RESETn, pin 84) typically requires a 10 kΩ pull-up to VCCIO plus an external reset supervisor IC for production designs.
Do NOT migrate between HC, HE, and ZE variants without redesigning the power supply - HC requires 2.5/3.3 V VCC, while HE and ZE require 1.2 V external VCC. The pinout is identical but the VCC rail is not interchangeable. Also avoid assigning general-purpose I/O to dedicated JTAG / Slave SPI / PROGRAMn / DONE / INITn pins unless you fully understand the configuration mode trade-offs (dedicated pins reduce to general-purpose after configuration completes). Estimated: typical standby current is 22 µW at 25 °C per datasheet; with all 68 I/O toggling at 50 MHz, dynamic current can rise to ~15-25 mA depending on toggle rate and load.
