Product details

The MSP430F2122IRHBT: The 24 general-purpose I/O lines and integrated 8-channel 10-bit ADC cover the typical analog interface needs of a small embedded controller.

Flash and RAM — sizing the firmware footprint

4 KB of Flash (4K x 8 plus 256 bytes) is the program storage ceiling. The 512 x 8 RAM limits stack depth and buffer allocation.

Serial connectivity and peripherals

The built-in brown-out detect and POR eliminate external reset supervision. A PWM output and watchdog timer round out the peripheral set for simple motor or LED control and system health monitoring. The internal oscillator means no external crystal is needed for basic operation, saving two pins and board space.

For dual-sourcing or a performance upgrade, the MSP430F2xx family includes pin-compatible variants with more Flash and RAM — a direct footprint swap without board redesign.

Frequently asked questions

What is the equivalent of MSP430F2122IRHBT?

Within the MSP430F2xx family, pin-compatible higher-density variants (e.g., MSP430F2132 with 8 KB Flash) share the same 32-VQFN footprint and peripheral set, offering a direct upgrade path without board changes. The C2000 F280041PZQR is a different architecture (32-bit C28x) and is not a functional equivalent for this 16-bit ultra-low-power MCU.
