It targets battery-powered sensor nodes and portable instrumentation requiring sub-µA standby current and fast wake-up.
For engineers reviewing the MSP430G2413IPW28R datasheet, MSP430G2413IPW28R pinout, MSP430G2413IPW28R application, or MSP430G2413IPW28R equivalent, key selection criteria include its 8 KB flash / 512 B RAM configuration, absence of integrated ADC10 (distinguishing it from G2x53 family), 28-pin TSSOP footprint, ultra-low-power operation down to 0.1 µA in LPM4, and Spy-Bi-Wire debug interface compatibility.
Technical Context
The MSP430G2413IPW28R implements a 16-bit CPU with constant generators and seven addressing modes, executing instructions in 62.5 ns at 16 MHz. Its clock system integrates a digitally controlled oscillator (DCO), internal low-frequency oscillator (VLO), and external crystal support (32 kHz), enabling sub-1 µs wake-up from LPM4 via ACLK or DCO.
Peripheral integration includes dual USCI modules supporting asynchronous UART with auto-baud detection (LIN), synchronous SPI, and I²C master/slave; a flexible analog comparator with eight input channels and slope A/D capability; and two independent 16-bit Timer_A modules (TA0 and TA1), each with three capture/compare registers and multiple clock sources (ACLK, SMCLK, TAxCLK).

FAQ
What is the maximum operating frequency of the MSP430G2413IPW28R?
The MSP430G2413IPW28R supports a maximum CPU clock frequency of 16 MHz via its digitally controlled oscillator (DCO), calibrated and stored in information memory segment A. This enables 62.5-ns instruction cycle time for deterministic real-time execution. The DCO operates across the full 1.8–3.6 V supply range and stabilizes in under 1 µs, making it suitable for burst-mode processing in ultra-low-power systems.
Does the MSP430G2413IPW28R include an integrated analog-to-digital converter (ADC)?
No, the MSP430G2413IPW28R does not include an integrated ADC10 module. It belongs to the G2x13 subfamily, which omits the 10-bit, 200-ksps ADC present in the G2x53 series (e.g., MSP430G2553). Instead, it provides an 8-channel analog comparator (Comp_A+) capable of slope A/D conversion and threshold detection - a lower-power alternative for basic analog monitoring tasks without digitization overhead.
Which debug interface does the MSP430G2413IPW28R support?
The MSP430G2413IPW28R supports the Spy-Bi-Wire (SBW) interface using pins 24 (RST/NMI/SBWTDIO) and 25 (TEST/SBWTCK) for in-system programming and real-time debugging. It does not support full 4-wire JTAG. SBW reduces PCB footprint and simplifies debug connector design while maintaining full flash erase/write, breakpoint, and register inspection capabilities through TI's Code Composer Studio and MSP-FET tools.
How many I/O pins does the MSP430G2413IPW28R have, and what are their key capabilities?
The MSP430G2413IPW28R provides 24 total I/O pins: P1.x (8 pins), P2.x (6 pins), and P3.x (8 pins, available only on 28-pin and 32-pin packages). All pins support individual direction control, pullup/pulldown resistors, interrupt-on-change, and capacitive-touch sensing via dedicated oscillator enable bits. Peripheral multiplexing includes UART, SPI, I²C, timer capture/compare, comparator inputs, and clock outputs - enabling flexible hardware resource allocation.
What are the power supply requirements for the MSP430G2413IPW28R?
The MSP430G2413IPW28R operates from a single 1.8 V to 3.6 V supply on DVCC (pin 1) referenced to DVSS (pin 28). It does not require separate analog supply (AVCC/AVSS) since it lacks ADC10. The brownout detector monitors DVCC and asserts reset if voltage falls below programmable thresholds (1.3–1.7 V), ensuring reliable startup and shutdown behavior in battery-powered systems with declining voltage profiles.
