48-VFQFN footprint and thermal pad routing
The MSP430F5244IRGZT ships in a 48-VFQFN exposed-pad package (7x7 mm body). The 0.50 mm pitch limits breakout to inner layers on a two-layer board — a four-layer stack with ground and power planes is the cleaner route for signal integrity on the I²C and SPI buses.
Memory headroom for a mixed-signal control loop
128 KB of Flash program memory paired with 8 KB of SRAM. The 8 KB RAM holds a moderate-size state machine and a few 100-byte buffers — enough for a PID loop with 10 sensor channels, but tight if you run a full TCP/IP stack. The 10-channel 10-bit ADC samples at up to 200 ksps; the DMA controller moves conversion results directly to RAM without CPU intervention, preserving the 25 MHz MIPS for the control algorithm.
Industrial temperature grade and peripheral set
The brown-out detect and POR reset the core cleanly on supply dips below 1.8 V; the watchdog timer catches firmware hangs. The internal oscillator trims to ±1% accuracy, sufficient for UART baud-rate generation without an external crystal in non-critical links.
Active lifecycle — sourcing posture
The base part number MSP430F5244 is the design anchor; the IRGZT suffix denotes the 48-VFQFN package and tape-and-reel packaging. The standard TI RoHS/REACH compliance declarations accompany the shipment.
