16-bit MCU for mixed-signal control — MSP430F5152IRSBR
The MSP430F5xx series 16-bit MCU runs at 25 MHz with 16 KB Flash and 2K x 8 RAM. It includes 31 I/O, an 11-channel 10-bit ADC, and I²C, SPI, UART interfaces.
16 KB Flash and 2K x 8 RAM — firmware fit
The 16 KB Flash is sized for moderate-complexity firmware — sensor calibration tables, PID loops, and communication stacks fit within that space. The 2K x 8 RAM handles a few hundred bytes of stack and variable storage; if your application buffers large telemetry packets or runs a real-time OS, you will need to budget memory carefully. The Flash is field-reprogrammable, so firmware updates are possible through the UART or SPI bootloader.
The MSP430F5152IRSBR has an Active lifecycle status but an end-of-life hot flag. This suggests a possible phase-out. We source it through independent channels; pricing and availability are confirmed at quote time.
