Product details

FRAM MCU for low-power sensing and control

It operates from a 1.8 V to 3.6 V supply and is rated over the industrial temperature range of -40°C to 85°C, suiting it for factory automation, sensor nodes, portable instrumentation, and outdoor telecom equipment.

2 KB of on-chip RAM handles stack and temporary buffers. FRAM can be partitioned into program and data segments.

The 1.8 V to 3.6 V supply range allows direct connection to a 3.6 V Li-ion cell or two alkaline cells in series, and the low-voltage floor means the MCU can stay operational as the battery discharges, extending system runtime.

The I²C and SPI ports handle common sensor and memory interfaces; the UART/USART modules support IrDA for wireless optical links if needed. Internal oscillator eliminates external crystal in many applications. Supports external low-frequency crystal for RTC.

Active product status from Texas Instruments. Available through independent distribution; pricing confirmed at quote.
