The 192 KB Flash and 18 KB RAM support a USB stack and control algorithm. The 113-ball BGA Microstar Junior (7x7 mm) requires controlled reflow and X-ray inspection. The 74 I/O break out to outer balls; inner balls carry supply and ground.","metaTitle":"TI MSP430F5631IZQWR 16-bit MCU, 20MHz, 192KB Flash, USB, Obsolete","metaDescription":"Texas Instruments MSP430F5631IZQWR 16-bit MCU with 20MHz CPU, 192KB Flash, 18KB RAM, USB 2.0, I2C/SPI/UART.
