Product details
Overview
MSP430F135IRTDR from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller featuring 16KB+256B flash, 512B RAM, a 12-bit ADC with 8 channels and <10 µs conversion time, one USART (UART/SPI), two 16-bit timers (Timer_A3 and Timer_B3), and on-chip comparator. It targets battery-powered sensor systems and portable measurement devices requiring sub-µA standby current and sub-6 µs wake-up.
For engineers reviewing the MSP430F135IRTDR datasheet, MSP430F135IRTDR pinout, MSP430F135IRTDR application, or MSP430F135IRTDR equivalent, key selection criteria include its single USART configuration, 48 I/O pins, VQFN-64 package, 1.8–3.6 V operation, and compatibility with TI's MSP430x1xx toolchain and development ecosystem.
Technical Context
The MSP430F135IRTDR implements a 16-bit CPU with constant generators and hardware multiplier for optimized code efficiency in low-power embedded control. Its clock system integrates DCO, ACLK, SMCLK, and MCLK domains with support for external crystals (XT1/XT2) and resistor-controlled oscillator (ROSC).
It executes instructions in 125 ns (at 8 MHz), supports five power-saving modes, and delivers active-mode current of 280 µA at 1 MHz/2.2 V. The ADC12 module operates with internal or external reference, sample-and-hold, and autoscan-enabling precise analog sensing without external components.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F133IRTDR | 8KB+256B flash, 256B RAM, identical peripheral set and pinout. | Lower memory capacity limits firmware complexity-suitable for simpler sensor nodes with minimal protocol stack or UI requirements. | Select when application firmware fits within 8KB flash and no future feature expansion is anticipated. |
| MSP430F149IPM | 60KB+256B flash, 2KB RAM, two USARTs, Timer_B7 (7 CC registers), 64-pin LQFP package. | Higher I/O count, dual serial interfaces, and expanded memory support complex protocols (e.g., Modbus RTU + UART debug) and larger code bases. | Choose for designs requiring second serial interface, more GPIO, or scalability beyond 16KB flash-accepts layout change due to LQFP vs. VQFN. |
Compared with MSP430F135IRTDR, MSP430F133IRTDR offers identical low-power performance but less memory for compact firmware, while MSP430F149IPM adds dual USARTs and higher memory at the cost of larger footprint and increased power in active mode-making MSP430F135IRTDR optimal for balanced cost, size, and capability in mid-complexity sensor edge nodes.

FAQ
What is the package type and pin count of the MSP430F135IRTDR?
The MSP430F135IRTDR uses a 64-pin VQFN (RTD) package with 9 mm × 9 mm body size and 0.4 mm pitch. It features 48 general-purpose I/O pins, plus dedicated analog, timer, communication, and JTAG signals. The exposed thermal pad must be soldered to DVSS for thermal and electrical integrity.
Does the MSP430F135IRTDR support both UART and SPI communication?
Yes, the MSP430F135IRTDR includes one USART (USART0) that can be configured in either asynchronous UART mode or synchronous SPI mode. Pin multiplexing allows shared use of P3.0–P3.4 for SPI slave functions or P3.4/P3.5 for UART transmit/receive-enabling flexible serial interface implementation without additional ICs.
What are the memory resources available on the MSP430F135IRTDR?
The MSP430F135IRTDR integrates 16KB of main flash memory plus 256B of information memory (for calibration data or boot code), and 512B of RAM. This configuration supports moderate firmware complexity-including sensor drivers, lightweight communication stacks, and data buffering-while maintaining low power consumption.
How does the ADC12 module on the MSP430F135IRTDR operate without external components?
The ADC12 module on the MSP430F135IRTDR includes an internal 2.5-V reference, sample-and-hold circuit, and autoscan capability. It accepts up to eight analog inputs (A0–A7 on Port 6) and achieves <10 µs conversion time-enabling direct connection of resistive sensors or voltage dividers without external op-amps or reference ICs.
Is the MSP430F135IRTDR pin-compatible with other devices in the MSP430F13x or MSP430F14x families?
The MSP430F135IRTDR shares the same 64-pin VQFN (RTD) footprint and signal mapping with MSP430F133IRTDR and all 64-pin MSP430F14x variants (e.g., MSP430F149IRTD). However, peripheral differences exist-such as single vs. dual USART and Timer_B3 vs. Timer_B7-so firmware and schematic review is required before substitution.
