The Texas Instruments MSP430F135IRTDR is a 16-bit microcontroller built around the MSP430 CPU16 core, clocked at 8 MHz. It carries 16 KB of Flash program memory and 512 bytes of RAM, with 48 general-purpose I/O lines and an 8-channel 12-bit ADC. The part operates from 1.8 V to 3.6 V and is rated for -40°C to 85°C, making it suitable for industrial control, sensor interfaces, and battery-powered instrumentation where low power and moderate compute are required.
8 MHz core — what it means for the control loop
At 8 MHz, the MSP430 CPU16 executes instructions in one or two clock cycles. The 512-byte RAM limits stack depth and buffering.
Industrial temperature range and package
The -40°C to 85°C rating covers most factory-floor, outdoor telecom, and automotive cabin environments. The 64-VFQFN (9x9 mm) exposed-pad package requires a thermal land on the PCB for heat dissipation; the pad is electrically connected to VSS. The Tape & Reel delivery suits automated pick-and-place for medium-to-high volume builds.
Lifecycle and sourcing
The MSP430F135IRTDR is listed as Active in production. It is sourced and quoted to order against an RFQ through independent distribution.
