20 MHz 16-bit MCU with USB and 256 KB Flash
The MSP430F5632IZCAR: Connectivity is a strong suit: the part integrates USB, I²C, SPI, UART/USART, LINbus, and IrDA, making it a single-chip interface hub for designs that talk to multiple serial buses. The 74 general-purpose I/O lines give plenty of headroom for sensor arrays, keypads, or display interfaces. On-chip peripherals include a brown-out detect/reset, DMA controller, POR, PWM, and watchdog timer — enough to keep the BOM lean without an external supervisor or reset IC in many applications.
Package and footprint
Housed in a 113-ball NFBGA (7x7 mm), the MSP430F5632IZCAR is a fine-pitch BGA that requires controlled reflow and X-ray inspection. The 113-VFBGA package code maps to the 7x7 mm body; the 'Z' in the order code flags the BGA variant, so verify board layout compatibility if you are migrating from a QFP sibling.
Lifecycle and sourcing
That removes the LTB pressure for new designs.
