What this MSP430F5508IRGZR brings to a mixed-signal control board
Connectivity covers I²C, IrDA, LINbus, SCI, SPI, UART/USART, and USB, making it a fit for sensor aggregation nodes, portable instruments, and USB-enabled data loggers that need one MCU to handle both the control loop and the host link.
16 KB of Flash (16K x 8) and 6 KB of SRAM (6K x 8).
USB connectivity is included.
Brown-out detect and POR are on-chip, so the reset circuit is minimal: just a decoupling cap and a pull-up on the RST pin.
Package and layout notes for the 48-VFQFN
The 31 I/O lines are enough for a keypad, a small LCD segment driver, and a handful of sensor interrupts.
