Product details

8 MHz, 48 KB Flash, 10 KB RAM — the MSP430F1611IRTDR's job in the assembly

It runs at 8 MHz and packs 48 KB of program Flash and 10 KB of RAM — enough headroom for sensor fusion loops, data logging, or a modest RTOS without reaching for a bigger part. The 48 I/O lines and integrated 8-channel 12-bit ADC plus dual 12-bit DACs let it handle analog conditioning and control output on a single chip, which keeps the BOM count low for industrial sensor nodes, portable instrumentation, and field-transmitter boards.

No commercial-grade downgrade to worry about if the board sees a cold start or a hot afternoon.

That means no last-time-buy deadline looming, no scramble for a replacement on the next rev.

Frequently asked questions

What is the closest pin-compatible alternative to MSP430F1611IRTDR in the MSP430x1xx family?

Pin-compatible siblings in the MSP430x1xx series share the same 64-VQFN footprint and peripheral set but differ in Flash and RAM density. The MSP430F1611IRTDR sits at the 48 KB Flash / 10 KB RAM tier; a lower-density sibling like the MSP430F155 has 16 KB Flash and 512 bytes RAM, while a higher-density option like the MSP430F1612 offers 55 KB Flash and 5 KB RAM. All maintain the same core, ADC/DAC, and I/O count, so a firmware recompile and memory-map adjustment are the only changes needed for a swap.
