LCMXO2-640HC-5TG100I

The LCMXO2-640HC-5TG100I is a MachXO2 family field programmable gate array (FPGA) in a 100‑pin LQFP package. It provides 640 logic elements and approximately 18 kbits of embedded SRAM, combined with 78 general-purpose I/Os and on-chip non-volatile flash resources suited for configuration and small user storage.

Designed for industrial-grade applications, the device offers instant-on non-volatile configuration, low standby power modes and a flexible I/O and memory feature set that supports a range of interface and glue-logic roles in embedded systems.

Key Features

• Logic Capacity  640 logic elements for implementing control, glue logic and small- to mid-scale programmable functions in-system.
• Embedded Memory  Approximately 18 kbits of on-chip SRAM (18,432 total RAM bits) for distributed storage and buffering; family selection indicates a 24 kbit on-chip user flash memory (UFM) for configuration and non-volatile storage on XO2-640 devices.
• I/O Density & Flexibility  78 I/Os provided in the 100‑LQFP package with programmable sysIO buffer support for multiple signaling standards documented for the MachXO2 family.
• Flexible I/O Standards  Programmable I/O buffer support across a wide range of interfaces including LVCMOS (3.3/2.5/1.8/1.5/1.2), LVTTL, PCI, LVDS, Bus-LVDS, MLVDS, RSDS, LVPECL, SSTL and HSTL as described in the family datasheet.
• Non‑volatile, Instant‑On Configuration  On-chip flash configuration supports instant-on operation (powers up in microseconds) and background programming of non-volatile memory.
• Power  Supports single-supply operation across a wide supply window (2.375 V to 3.465 V) and includes ultra low-power modes highlighted for the MachXO2 family.
• Clocking and Synchronous I/O  Family-level features include multiple primary clocks and source-synchronous I/O capabilities such as DDR registers in I/O cells and gearing options documented for MachXO2 devices.
• Package & Environmental  100‑pin LQFP (14 mm × 14 mm) surface-mount package; industrial grade with an operating temperature range of −40 °C to 100 °C and RoHS compliance.

Typical Applications

• Interface and Glue Logic  Use the device's 640 logic elements and 78 I/Os to implement bus bridging, protocol adaptation and peripheral interface consolidation without external glue chips.
• Configuration & Control Storage  On-chip user flash memory (UFM) and embedded SRAM allow implementation of configuration storage, small parameter storage or soft PROM roles within a single chip.
• Source‑Synchronous I/O Tasks  Pre-engineered source-synchronous I/O features, DDR registers in I/O cells and gearing support are well suited for display interface timing, DDR-style datapaths and high-speed I/O staging.
• Low‑Power Standby Functions  Ultra low-power standby capabilities enable retention and quick-resume control functions in power-sensitive embedded systems.

Unique Advantages

• Non‑volatile Instant Configuration: On-chip flash provides instant-on operation and reduces the need for external configuration memory.
• Compact, Integrated Implementation: Embedded SRAM and on-chip UFM reduce external memory requirements and simplify BOM for control and small buffering needs.
• Wide I/O Compatibility: Programmable sysIO buffers support many common signaling standards, enabling flexible interfacing to a broad set of peripherals and subsystems.
• Industrial Temperature Range: Rated for −40 °C to 100 °C operation, supporting deployments in harsh or wide-temperature environments.
• Single‑Supply Operation: Broad supply range (2.375 V to 3.465 V) eases power-rail design and integration with varied system voltages.
• RoHS Compliant: Environmentally compliant packaging suitable for modern manufacturing processes.
