16MHz MSP430 core with 32KB flash — what the specs mean for your BOM
The MSP430F247TRGCR is a 16-bit microcontroller from the MSP430F2xx series, running the MSP430 CPU16 core at 16 MHz. That clock speed sets the processing ceiling — the 16-bit RISC architecture executes most instructions in a single cycle, so the MIPS rate tracks the clock directly. Program memory is 32 KB of flash (32 K × 8 plus 256 B of information memory), which holds the application code and calibration constants. The 4 K × 8 SRAM is the working memory — budget it for stack depth, interrupt context, and data buffers before committing the firmware architecture.
Package, I/O, and peripheral mix — board-fit and integration
The 0.5 mm pitch QFN demands careful stencil design — the pad-to-pad spacing is tight enough that solder bridging between adjacent pins is a risk if the aperture ratio isn't dialled in. Pin 1 is marked by a chamfered corner on the package, visible under magnification. 48 general-purpose I/O lines are available, multiplexed with the peripheral functions. An 8-channel 12-bit ADC handles analog inputs like thermistors or potentiometers directly. On-chip peripherals include brown-out detect, power-on reset, and a watchdog timer — these handle the power-up sequence and fault recovery without external supervisor ICs. The internal oscillator means no external crystal is needed for basic operation, though the accuracy is lower than a ceramic resonator.
Lifecycle status and compliance — active production, no EOL risk
RoHS3 compliant (2011/65/EU + 2015/863), with no exemptions expiring. The part is lead-free and compatible with lead-free reflow profiles.
