Memory and peripheral budget for tight BOM lines
With 2 KB Flash and 128 bytes of RAM, the MSP430F2013TRSAT is sized for firmware that fits in a few hundred instructions — think reading a sensor, driving a PWM output, or managing a simple I²C/SPI peripheral.
The 10 available I/O lines include the ADC inputs and serial interface pins — the pinout is fixed, so the PCB footprint should match the supplier device package drawing.
