The 18 KB RAM, though, is the tighter constraint. If your design streams USB audio or buffers large sensor arrays, you'll need to budget that 18 KB carefully; the DMA controller helps move data without CPU intervention.","metaTitle":"MSP430F5634IZQWR – TI MSP430F5xx 16-bit MCU, 20MHz, 192KB Flash, obsolete","metaDescription":"TI MSP430F5634IZQWR 16-bit MCU with MSP430 CPUXV2 core, 20MHz, 192KB Flash, 18KB RAM, USB 2.0, 74 I/O, -40 to 85°C.
