Product details

FRAM memory: the main event

The 2 KB SRAM handles stack and scratchpad. An integrated 8-channel 12-bit ADC and an LCD driver reduce external BOM count for metering or display applications.

The 51 general-purpose I/O lines give headroom for parallel LCD data buses or keypad matrices. On-chip brown-out detect and POR eliminate external supervisor ICs.

Housed in a 64-VFQFN with exposed pad (supplier package 64-VQFN 9x9 mm). The exposed pad also makes hand rework trickier: preheat the board to 150°C before hot-air removal, and use a low-temp solder paste for reballing to avoid lifting the pad.

Listed as Active, so no near-term EOL risk for production programs. For dual-sourcing, TI's MSP430FRAM family includes pin-compatible density variants (e.g., 32 KB or 128 KB FRAM) that share the same 64-VQFN footprint — check the base product number MSP430FR69721 for the exact memory and peripheral set.

Frequently asked questions

Is MSP430FR69721IRGCR obsolete or active?

Active. The lifecycle status is Active, meaning TI continues to manufacture and support this part for new designs.

What is the MSP430FR69721IRGCR microcontroller?

It is a 16-bit ultra-low-power MCU from TI's MSP430 FRAM series, with a CPUXV2 core running at 16 MHz, 64 KB FRAM program memory, 2 KB SRAM, 51 I/O, an 8-channel 12-bit ADC, and an LCD driver — all in a 64-VQFN package.

What are the alternatives to MSP430FR69721IRGCR?

Within the MSP430FRAM family, pin-compatible density variants (e.g., 32 KB or 128 KB FRAM) share the same 64-VQFN footprint and peripheral set.
