Product details

8 MHz 16-bit MCU with 4 KB Flash — what fits in this memory envelope

That memory budget suits a single control loop, a few sensor readings, and a simple state machine — think a thermostat, a battery monitor, or a basic motor controller. The 14 I/O lines and 8-channel 10-bit ADC cover most low-pin-count analog sensing tasks without external muxing.

Active lifecycle — no near-term obsolescence

For MRO stock and production BOMs, this means the supply channel remains open through normal distribution.

Frequently asked questions

What is the closest pin-compatible alternative to MSP430F1122IDWR in this family?

Within the MSP430x1xx series, higher-density siblings like the MSP430F1232IDWR share the same 20-SOIC footprint and supply range but offer more Flash and RAM. Check the specific memory and peripheral differences against your firmware image size before substituting.

What is MSP430F1122IDWR's listed speed?

The core runs at 8 MHz. That is the maximum clock frequency; the internal oscillator can be trimmed, and an external clock source can be used if tighter timing is needed.
