LCMXO2-640HC-6SG48C

The LCMXO2-640HC-6SG48C is a MachXO2 field programmable gate array (FPGA) in a compact 48‑VFQFN exposed pad package. It provides 640 logic elements with approximately 18 kbits of embedded RAM and 40 user I/Os, making it suitable for commercial‑grade embedded designs that require non‑volatile, reconfigurable logic in a small footprint.

Designed for low‑power, instant‑on applications, this device combines on‑chip user flash memory, flexible programmable I/O, and in‑system programmability to support control, interface, and glue‑logic functions in space‑constrained systems.

Key Features

• Logic Capacity — 640 logic elements for implementing glue logic, state machines, and small hardware accelerators.
• Embedded Memory — Approximately 18 kbits (18,432 bits) of on‑chip RAM for LUTRAM and buffering, plus on‑chip user flash memory (UFM) capacity reported for the family at up to 24 kbits with 100,000 write cycles.
• I/O and Connectivity — 40 programmable I/Os in a small package, with family support for a wide range of I/O standards and programmable buffer modes for flexible interfacing.
• Non‑volatile Configuration — On‑chip user flash provides instant‑on behavior and supports background programming and in‑field updates via supported interfaces.
• Power and Voltage — Single supply operation across a 2.375 V to 3.465 V range, enabling compatibility with common system power rails.
• Package and Mounting — 48‑VFQFN exposed pad (48‑QFN, 7 mm × 7 mm) surface‑mount package for compact PCB designs and efficient thermal path through the exposed pad.
• Operating Range and Compliance — Commercial grade operation from 0 °C to 85 °C and RoHS‑compliant packaging.
• System Integration Features — Family features include IEEE 1149.1 boundary scan, programmable serial interfaces (SPI, I2C), on‑chip timers/counters, and unique TraceID for system tracking and inventory.

Typical Applications

• Interface and Glue Logic — Implement protocol bridging, pin‑reassignment and board‑level interfacing where compact, reconfigurable logic is needed.
• User Interface Control — Drive and manage display or keypad interfaces with programmable I/Os and embedded memory for control state.
• Embedded System Control — Offload peripheral timing, state machines, or custom logic functions in commercial embedded products requiring instant‑on non‑volatile configuration.
• Field Upgradable Systems — Enable in‑field logic updates and background programming using on‑chip user flash and supported configuration modes.

Unique Advantages

• Compact, low‑profile package: The 48‑VFQFN exposed pad (7×7 mm) delivers a small PCB footprint with an exposed pad for improved thermal conduction.
• Non‑volatile instant‑on: On‑chip user flash enables microsecond‑scale power‑up and eliminates the need for external configuration memory for many applications.
• Flexible single‑supply operation: Supports a broad supply range (2.375 V to 3.465 V), simplifying power architecture and enabling compatibility with common system rails.
• Embedded memory and UFM: Approximately 18 kbits of RAM plus on‑chip user flash (family UFM up to 24 kbits) provide local storage for state, configuration and small data buffers.
• Programmable I/Os with rich system features: 40 I/Os and family‑level support for serial interfaces, boundary scan and system tracking reduce external components and simplify board design.
