Overview of LCMXO2-640HC-6TG100C – MachXO2 FPGA, 640 logic elements, 100‑LQFP
The LCMXO2-640HC-6TG100C is a MachXO2 family Field Programmable Gate Array (FPGA) from Lattice Semiconductor Corporation, provided in a 100‑pin LQFP package. It delivers 640 logic elements, 78 I/Os and approximately 18.4 kbits of on-chip RAM, making it suitable for compact system control, I/O bridging and interface tasks where non-volatile, instant-on programmable logic is needed.
Built on the MachXO2 architecture, this device emphasizes low-power operation, flexible I/O and embedded system support—enabling designers to integrate glue logic, peripheral interfaces and control functions while keeping BOM count and board area low.
Key Features
- Core Logic 640 logic elements (cells) with 80 CLBs, providing compact programmable logic capacity for glue logic, state machines and small accelerators.
- On‑chip Memory Total RAM: 18,432 bits of embedded memory for distributed RAM and small buffering needs.
- I/O Flexibility 78 general-purpose I/Os with programmable buffer options (family supports wide range of I/O standards and programmable differential I/O features) for flexible interfacing to peripherals and bus standards.
- Power and Voltage Single supply operation across 2.375 V to 3.465 V, with family-level ultra low power capabilities including micro-watt standby modes.
- Non-volatile Configuration MachXO2 family provides instant-on, single-chip non-volatile reconfiguration and in-field reconfiguration options (TransFR) for firmware updates while in the field.
- System Integration On-chip system-level functions available in the family such as SPI, I²C, timer/counter and an internal oscillator help reduce external component count.
- Package & Temperature 100‑pin LQFP package (supplier lists 100‑TQFP, 14×14 mm) and commercial operating temperature range of 0 °C to 85 °C.
- Standards & Reliability RoHS compliant and produced by Lattice Semiconductor, leveraging the MachXO2 family feature set for field-updatable, single-chip solutions.
Typical Applications
- Embedded Control & Glue Logic Replace discrete glue logic and microcontrollers for board-level control, configuration handling and simple protocol bridging using the device’s programmable logic and I/O resources.
- Peripheral and Sensor Interfaces Interface sensors, buttons and external peripherals with flexible I/O standards and on‑chip timers/counters and serial interfaces.
- Display and Memory Interfaces Support display or memory interface functions using the family’s pre-engineered source-synchronous I/O features and DDR-capable I/O cells where applicable.
- In-field Updatable Logic Enable in-system logic updates and dual-boot designs with background programming and TransFR reconfiguration for product feature upgrades.
Unique Advantages
- Compact, Non‑volatile FPGA: Instant-on, single-chip MachXO2 architecture removes the need for separate configuration memory and simplifies startup sequencing.
- Low standby power: Family-level ultra low power options (micro-watt standby ranges) help reduce overall system power for always-on applications.
- Rich I/O capability: 78 I/Os with programmable buffer options enable flexible interfacing to a variety of peripheral standards and signals, reducing external level-shifters and transceivers.
- System-level integration: On-chip SPI, I²C, timers and oscillator reduce external components and speed integration of control and monitoring functions.
- Field-upgradable logic: Support for in-field reconfiguration (TransFR) and background programming simplifies firmware evolution and serviceability.
