The peripheral set includes an 8-channel 10-bit ADC, a USI module that handles both I²C and SPI, plus a DMA controller and a PWM timer — enough to run a small sensor-fusion loop or a single-ended data-acquisition channel without external glue. ## 16MHz core and 8KB Flash — what the memory budget really means At 16MHz the MSP430 CPU16 executes most instructions in a single cycle, so a tight sensor-polling loop or a bit-banged UART at 115200 baud is manageable. The 8KB Flash is the hard constraint: a typical bootloader plus a TI driverlib stub leaves about 5KB for application code, which is comfortable for a single I²C temperature sensor with logging, but tight if you need a full USB stack or floating-point math in software. The 256-byte RAM limits stack depth — keep interrupt nesting shallow and allocate buffers sparingly, or the linker will tell you at build time. The MSP430G2xx family has broad distribution support, and the part is ROHS3 compliant. ## Package and footprint: 20-TSSOP The 20-TSSOP body measures 4.40mm wide (0.173\") with a 0.65mm pin pitch — a compact footprint that fits on two-layer boards without micro-vias.","metaTitle":"Texas Instruments MSP430G2452IPW20R 16-Bit MCU, 8KB Flash","metaDescription":"TI MSP430G2452IPW20R 16-bit MCU with 8KB Flash, 256B RAM, 16MHz core, 8x10b ADC, I²C/SPI, -40°C to 85°C, 20-TSSOP.
