LCMXO640C-4TN100C

The LCMXO640C-4TN100C is a MachXO family FPGA in a 100-pin LQFP surface-mount package optimized for glue logic, bus interfacing and control applications. It delivers 640 logic elements arranged across 80 CLBs, up to 74 user I/Os, and supports single-chip, non-volatile configuration for instant-on operation.

Designed for commercial applications, this device operates from 1.71 V to 3.465 V and across a 0 °C to 85 °C ambient range, providing flexible I/O and system-level configuration options suitable for low- to mid-density logic integration.

Key Features

• Core Logic 640 logic elements implemented across 80 CLBs provide mid-density programmable logic capacity for glue logic, control and interface functions.
• Memory Approximately 6.1 Kbits of distributed RAM for small FIFOs and state storage; no embedded block SRAM (EBR) blocks in this device.
• Flexible I/O 74 I/O pins with programmable sysIO buffer support for a wide range of standards including LVCMOS (1.2/1.5/1.8/2.5/3.3 V) and legacy interfaces, enabling direct interfacing to common peripherals and buses.
• Non‑volatile Configuration & Instant‑on Single-chip, non-volatile configuration enables instant-on behavior without external configuration memory and supports JTAG programming and background programming of non-volatile memory.
• In-field Reconfiguration & Low-power Modes Supports in-field logic updates (TransFR reconfiguration) and a Sleep Mode that can reduce static current significantly for low-power standby operation.
• Package & Mounting 100-pin LQFP (14 × 14 mm) surface-mount package with a 74 I/O pinout suitable for compact board layouts and straightforward assembly.
• Commercial Grade & Compliance Rated for 0 °C to 85 °C operation and RoHS compliant.

Typical Applications

• Glue Logic and System Control — Implement address decoding, bus arbitration, reset/power sequencing and other board-level control tasks with compact, non-volatile logic.
• Bus Bridging and Interfacing — Bridge between different voltage domains and bus protocols using flexible I/O and programmable logic.
• Peripheral and Sensor Interfaces — Aggregate and preprocess sensor data or manage peripheral handshakes with distributed RAM and reconfigurable logic.
• Power-up and Sequencing Control — Implement deterministic power-up control and instant-on functionality without external configuration memory.

Unique Advantages

• Instant-on, single-chip configuration: Eliminates the need for external configuration memory and delivers immediate availability at power-up.
• In-field logic updates: TransFR reconfiguration enables targetted logic changes while the system remains operational, simplifying firmware updates and field fixes.
• Flexible I/O standards: Programmable I/O buffers support multiple voltage domains and interface standards, reducing the need for external level-shifters or translators.
• Compact, surface-mount package: 100-pin LQFP (14×14 mm) package balances I/O count and board space for compact designs.
• Simplified low-power operation: Sleep Mode capability provides a substantial reduction in static current for power-sensitive applications.
• Design tool support: Supported by ispLEVER design tools and common synthesis flows to streamline implementation and timing closure.
