LCMXO2-640ZE-2TG100C

The LCMXO2-640ZE-2TG100C is a MachXO2 family Field Programmable Gate Array (FPGA) IC from Lattice Semiconductor, offered in a 100‑pin LQFP (14×14 mm) surface‑mount package. The device provides 640 logic elements, 18,432 bits of on‑chip RAM and 78 user I/Os, making it suitable for compact control, glue‑logic and low‑power programmable logic tasks in commercial applications.

As part of the MachXO2 family, this device aligns with the series’ flexible logic architecture, embedded memory and non‑volatile configuration capabilities to support instant‑on and reconfigurable in‑field updates.

Key Features

• Core Logic — 640 logic elements for implementing glue logic, state machines and small to medium combinational/sequential logic functions.
• On‑Chip Memory — 18,432 total RAM bits available for distributed RAM and small data buffers.
• I/O Capability — 78 I/Os in the 100‑LQFP package to support multiple peripherals, signaling standards and board connections.
• Non‑volatile, Reconfigurable Architecture — MachXO2 family features include on‑chip user flash for instant‑on operation and support for in‑field logic updates.
• Flexible I/O Buffering — Family-level I/O support for a wide range of interfaces (programmable buffer options and differential signaling are supported across the MachXO2 family).
• Power — Single supply operation with a supply voltage range of 1.14 V to 1.26 V and family-level low‑power design options.
• Package & Mounting — Surface mount 100‑LQFP (Supplier package listed as 100‑TQFP, 14×14 mm) for PCB designs with a compact footprint.
• Temperature & Grade — Commercial grade with an operating temperature range of 0 °C to 85 °C.
• Environmental Compliance — RoHS compliant.

Typical Applications

• Consumer Electronics — Implements control logic, protocol bridging and user interface control where compact programmable logic is required.
• Display and Video Subsystems — Family features include source synchronous I/O and gearing for display interfaces, useful for driving or interfacing panel logic.
• Memory Interface Glue Logic — Supports DDR/DDR2/LPDDR family features for pre‑engineered source synchronous interfaces and memory control functions.
• Embedded System Control — On‑chip flash and embedded peripherals allow system-level functions such as SPI/I2C control and soft‑processor PROM storage.

Unique Advantages

• Compact, Usable Logic Density: 640 logic elements and 78 I/Os in a 100‑pin LQFP package enable integration of multiple functions into a small footprint.
• On‑Chip Memory and Configuration: 18,432 bits of RAM plus on‑chip user flash support local buffering and non‑volatile configuration for instant‑on operation.
• Flexible I/O Support: MachXO2 family I/O flexibility enables a broad range of interface standards and hot‑socketing capability on board designs.
• Low‑Power Family Characteristics: The MachXO2 family is designed for low standby power and power‑saving options suitable for energy‑sensitive applications.
• Commercial Temperature Range: Rated for 0 °C to 85 °C to match typical commercial product environments.
• Regulatory and Assembly Friendly: Surface‑mount 100‑LQFP packaging and RoHS compliance simplify manufacturing and regulatory acceptance for commercial products.
