LCMXO2-640ZE-1TG100I

The LCMXO2-640ZE-1TG100I is a MachXO2 family FPGA from Lattice Semiconductor, offering non-volatile, instant-on programmable logic in a compact 100‑pin LQFP package. Built around a flexible logic architecture, this industrial‑grade device combines 640 logic elements with approximately 18 kbits of embedded RAM and 78 I/Os to address system glue, interface bridging, and control tasks where low power, compact footprint, and fast start-up are important.

Key Features

• Core Logic — 640 logic elements provide the programmability needed for glue logic, finite state machines, and custom interfaces.
• Embedded Memory — Approximately 18 kbits (18,432 bits) of on‑chip RAM for distributed storage and FIFO implementations.
• I/O Flexibility — 78 user I/Os with the MachXO2 sysIO buffer capabilities described for the family, supporting a wide range of interfaces and programmable I/O termination and pull modes.
• Low Power Architecture — Family‑level low power design (advanced 65 nm low power process) with standby modes and microsecond‑scale instant‑on behavior to reduce system power impact.
• Non‑volatile Configuration — MachXO2 family supports on‑chip user flash memory and background programming; devices power up instantly with stored configuration data.
• Clocking and Timing — Flexible on‑chip clocking including multiple primary clocks and edge clocks for high‑speed I/O interfaces, enabling synchronous, source‑synchronous designs.
• Package & Environmental — Surface‑mount 100‑LQFP (100‑TQFP, 14×14 mm) package; RoHS compliant and specified for industrial temperature operation from −40°C to 100°C.
• Supply Voltage — Operates from 1.14 V to 1.26 V for core supply compatibility in low‑voltage system designs.

Typical Applications

• Industrial Control — I/O aggregation, protocol translation, and timing control in industrial automation systems, taking advantage of industrial temperature rating and flexible I/O.
• Interface Bridging — Implement SPI/I²C/JTAG interfacing and custom protocol bridges using on‑chip logic and the device’s programmable I/O capabilities.
• System Glue Logic — Replace fixed glue components with reprogrammable logic for board-level signal conditioning, reset and power sequencing, and control logic consolidation.
• Display and High‑Speed I/O Support — Use family‑level source synchronous I/O and gearing features for display or high‑speed peripheral interface requirements.

Unique Advantages

• Instant‑on, Non‑volatile Operation: Powers up in microseconds with stored configuration, enabling fast system boot and simplified initialization.
• Compact, Industrial‑Ready Package: 100‑pin LQFP packaging and −40°C to 100°C rating make it suitable for space‑constrained, industrial environments.
• High I/O Count for Integration: 78 I/Os allow consolidation of multiple discrete interfaces and reduction of external components.
• Embedded RAM for Local Storage: Approximately 18 kbits of on‑chip RAM supports FIFOs and small data buffers without external memory.
• Low Core Voltage: 1.14 V to 1.26 V core supply supports modern low‑voltage system architectures and power optimization.
• Family‑level Feature Set: Benefits from MachXO2 family functions such as programmable I/O standards, system clocks, and background reprogramming options.
