On-chip connectivity includes USB, I²C, IrDA, LINbus, SCI, SPI, UART/USART, and a 16-channel 12-bit ADC for analog sensor acquisition. ## Memory and peripheral headroom for system design With 256 KB of flash and 18 KB of RAM, the MSP430F6635IZQWT supports moderate-complexity firmware stacks — a USB stack plus a real-time scheduler and sensor fusion library fit within the flash budget, leaving room for field-upgradeable application code. The 16-channel 12-bit ADC and built-in DMA controller allow continuous data logging from multiple analog channels without CPU intervention, freeing the core for protocol handling and control loops. Housed in a 113-VFBGA Microstar Junior package measuring 7x7 mm, the MSP430F6635IZQWT requires a multi-layer PCB for fan-out of the fine-pitch BGA balls. The 0.50 mm ball pitch demands careful via-in-pad or microvia planning to route all 74 I/O and supply rails. Texas Instruments has designated the MSP430F6635IZQWT as obsolete. No official successor part number is listed in the lifecycle record.","metaTitle":"Texas Instruments MSP430F6635IZQWT MCU, 20MHz, 256KB Flash","metaDescription":"Texas Instruments MSP430F6635IZQWT 16-bit MCU, 20MHz, 256KB flash, 18KB RAM, 74 I/O, USB, 12-bit ADC, 113-VFBGA, -40 to 85°C.
