8 KB Flash, 256 bytes RAM — sizing the firmware envelope
Program memory is 8 KB of Flash (8K x 8), paired with 256 x 8 bytes of RAM. That is a tight but workable footprint for a single-function sensor node, a brushless-DC commutation controller, or a simple I²C/SPI bridge. If your application needs over-the-air updates or a full RTOS heap, you will bump into the ceiling — this part is sized for bare-metal, code-constrained firmware, not a feature-rich stack.
The MSP430 CPU16 core runs at 16 MHz. That is enough throughput to service a 10-bit ADC conversion sequence, toggle a PWM output at audio frequencies, and handle a USI-based I²C or SPI transaction without stalling. It is not a number-cruncher — expect around 16 MIPS peak. For a battery-powered thermostat or a capacitive-touch interface, that is the sweet spot between active current draw and responsiveness.
14-TSSOP with 10 I/O — footprint and routing
Housed in a 14-TSSOP (4.40 mm wide body), the part offers 10 general-purpose I/O pins. That is enough for a handful of sensor inputs, a small character LCD, or a few pushbuttons and LEDs. The 0.65 mm pitch is comfortable for hand-assembly prototypes and standard PCB fab tolerances. No exposed pad — all dissipation goes through the leads, so keep the load current per pin within the datasheet limits.
On-chip peripherals: ADC, PWM, brown-out, DMA
The integrated peripherals include an 8-channel 10-bit ADC, a brown-out detect and POR circuit, a PWM timer, and a DMA controller. The USI module handles both I²C and SPI in hardware — no bit-banging.
