Product details

256-byte RAM budget — plan the stack and buffers first

With 256 x 8 of RAM, every byte counts. The firmware engineer needs to size the call stack, interrupt vectors, and any I²C or SPI buffers against that ceiling before writing a line of code. The 2 KB Flash is tight too — the bootloader, main loop, and peripheral drivers have to fit in that footprint. If the application needs more headroom, the MSP430F2xx family scales up in compatible pinouts.

An 8-channel 10-bit ADC brings analog sensor data into the digital domain without an external converter.

Housed in a 32-VFQFN exposed-pad package (5x5 mm body), the MSP430F2112IRHBT is a surface-mount part. The exposed pad also provides a low-inductance ground return, which helps with ADC noise.

Frequently asked questions

Is MSP430F2112IRHBT a replacement for MSP430F2112IRHB?

The order code MSP430F2112IRHBT and MSP430F2112IRHB differ only by the suffix — the base product number MSP430F2112 is identical. The 'T' suffix typically indicates Tape & Reel packaging. Verify the exact package code and temperature range in the datasheet for your specific BOM line.

Can MSP430F2112IRHBT be used with Arduino IDE?

The MSP430F2112IRHBT is not an Arduino-platform target. It uses TI's MSP430 toolchain (CCS, IAR, or Energia). Energia provides an Arduino-like environment for MSP430, but the 2 KB Flash and 256-byte RAM limit the library support compared to larger MSP430 parts.
