The part integrates a 10-bit ADC with eight channels, an internal oscillator (no external crystal needed for most applications), and serial connectivity spanning I²C, SPI, UART, IrDA, and LINbus. Twenty-four general-purpose I/O lines provide ample headroom for keypad scanning, LED driving, or discrete sensor inputs. ## Memory and peripheral budget for the BOM line 16 KB of Flash means the firmware image must be lean — typical for a single-function control task (e.g., a thermostat or occupancy sensor). The 512-byte RAM limits data buffering to a few hundred bytes; if your application needs a large frame buffer or multi-packet serial queue, step up to the 1 KB RAM variants in the MSP430G2xx family. The on-chip 10-bit ADC with eight channels covers most analog sensor interfaces without an external converter.","metaTitle":"TI MSP430G2533IRHB32R MCU, 16-bit, 16MHz, 16KB Flash, 32VQFN","metaDescription":"Texas Instruments MSP430G2533IRHB32R 16-bit MCU, 16MHz, 16KB Flash, 512B RAM, -40°C to 85°C, 32-VQFN.
