16 MHz MSP430 core with 2 KB flash for sensor and control loops
The Texas Instruments MSP430F2112TPW is a 16-bit microcontroller from the MSP430F2xx series, clocked at 16 MHz. The 2 KB (2K x 8 + 256B) on-chip flash and 256 x 8 bytes of RAM define the firmware and data budget — adequate for small sensor fusion, actuator sequencing, or communication protocol handling in embedded control applications. The 8-channel 10-bit analog-to-digital converter (A/D 8x10b) allows direct connection of analog sensors — thermistors, potentiometers, or current shunts — without an external ADC. The -40 °C to +105 °C temperature range (TA) qualifies it for industrial enclosures, automotive cabin, or outdoor equipment where ambient temperatures exceed the commercial 85 °C ceiling.
24 general-purpose I/O pins are available, along with serial connectivity covering I²C, IrDA, LINbus, SCI, SPI, and UART/USART. This range supports common sensor buses (I²C, SPI) and industrial fieldbus links (LIN) without external bridge ICs. On-chip peripherals include brown-out detect/reset (BOR), power-on reset (POR), pulse-width modulation (PWM), and a watchdog timer (WDT). The BOR and POR circuits ensure deterministic startup and safe shutdown during supply transients — critical for battery-powered or remote equipment that may experience intermittent power. The supplier device package is 28-TSSOP, matching the package/case designation.
