Overview
MSP430F5152IDAR from Texas Instruments is a 16-bit ultra-low-power mixed-signal microcontroller featuring 16 KB Flash, 2 KB RAM, dual 16-bit Timer_D modules (TD0/TD1), USCI_A0 (UART/IrDA/SPI) and USCI_B0 (I²C/SPI), 10-bit 200-ksps ADC with 8 external + 2 internal channels, and 16-channel comparator. It operates from 1.8 V to 3.6 V and targets battery-powered sensor systems and digital power supplies.
For engineers reviewing the MSP430F5152IDAR datasheet, MSP430F5152IDAR pinout, MSP430F5152IDAR application, or MSP430F5152IDAR equivalent, key selection criteria include its 16 KB Flash capacity, 5-V-tolerant I/Os with 20-mA drive strength, sub-5 µs wake-up from LPM3, integrated LDO with programmable core voltage, and support for 32-kHz and up to 25-MHz crystal oscillators.
Technical Context
The MSP430F5152IDAR implements a 16-bit RISC CPUXV2 core with constant generators and 40-ns instruction cycle time. Its unified clock system integrates FLL-based frequency stabilization, VLO (10 kHz), REFO (32.768 kHz), and dual crystal oscillator support (XT1 for LF/HF).
Power management includes five low-power modes (LPM0–LPM4.5), programmable LDO regulation, supply voltage supervision (SVM/SVS), and brownout reset. Peripheral integration features 3-channel DMA, hardware 32-bit multiplier, CRC16 engine, and port mapping controller enabling flexible I/O function assignment.

FAQ
What is the maximum operating frequency of the MSP430F5152IDAR?
The MSP430F5152IDAR supports a maximum system clock (MCLK) frequency of 25 MHz when using an external high-frequency crystal (XT1). Its digitally controlled oscillator (DCO) is factory-trimmed and FLL-stabilized to achieve this rate with ±1% accuracy across voltage and temperature, enabling high-speed computation while maintaining ultra-low-power efficiency.
Does the MSP430F5152IDAR support hardware debugging?
Yes, the MSP430F5152IDAR supports hardware debugging via the Spy-Bi-Wire (SBW) interface using the RST/NMI/SBWTDIO and TEST/SBWTCK pins. This two-wire interface allows full JTAG-equivalent functionality - including breakpoint setting, register inspection, and flash programming - with minimal PCB footprint and no external debug header required.
Can the MSP430F5152IDAR operate from a single 1.8 V supply?
Yes, the MSP430F5152IDAR is fully specified to operate from 1.8 V to 3.6 V. At 1.8 V, it maintains full functionality including 16 KB Flash execution, 2 KB RAM access, 10-bit ADC operation (with reduced sample rate), and all timers and USCI modules - making it ideal for energy-harvesting and coin-cell-powered applications.
How many I²C interfaces does the MSP430F5152IDAR include?
The MSP430F5152IDAR includes one dedicated I²C interface implemented in USCI_B0. This module supports standard-mode (100 kbps) and fast-mode (400 kbps) I²C communication, 7-bit and 10-bit addressing, and multi-master arbitration - sufficient for connecting to EEPROMs, temperature sensors, and display controllers in compact embedded systems.
Is the ADC on the MSP430F5152IDAR capable of internal temperature sensing?
Yes, the MSP430F5152IDAR's 10-bit ADC includes an internal temperature sensor channel accessible as an internal ADC input. When enabled, it provides calibrated voltage output proportional to die temperature, allowing accurate on-chip thermal monitoring without external components - a key feature used in thermal management of MSP430F5152IDAR-based power supplies and motor controllers.
