For a 16-bit MSP430 core, that translates to roughly 8 MIPS. This is sufficient for slow-loop sensor acquisition, periodic ADC reads, and serial communication at standard baud rates, but it will not sustain heavy DSP or real-time control loops above a few kilohertz. ## 48 KB Flash — firmware capacity and field updates With 48 KB of Flash (48K x 8 plus 256 bytes), this MCU holds a moderate-sized firmware image. The Flash is in-system programmable, so field updates are possible if the bootloader supports it. The 2K x 8 RAM is tight for data buffering — expect to manage stack and global variables carefully, especially when using the ADC or DMA. ## Obsolete — sourcing reality and the replacement path Texas Instruments has marked the MSP430F168IRTDR as obsolete. The manufacturer no longer produces the part, and no last-time-buy window is currently open. Surface-mount assembly is standard, and the package pitch is fine enough to require careful soldering profiles.","metaTitle":"TI MSP430F168IRTDR 16-bit MCU, 8MHz, 48KB Flash, 2K RAM, Obsolete","metaDescription":"Texas Instruments MSP430F168IRTDR 16-bit MSP430 CPU16 MCU, 8MHz, 48KB Flash, 2K x 8 RAM, 48 I/O, I²C/SPI/UART, 64-VFQFN, -40°C to 85°C.
