Product details
Overview
MSP430F5152IRSBT 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 control.
For engineers reviewing the MSP430F5152IRSBT datasheet, MSP430F5152IRSBT pinout, MSP430F5152IRSBT application, or MSP430F5152IRSBT equivalent, key selection criteria include its 40-pin QFN (RSB) package, 5-V-tolerant I/Os with 20-mA drive strength, sub-5-µs wake-up from LPM3, and integrated LDO with programmable core voltage - all critical for low-power embedded design validation and BOM optimization.
Technical Context
The MSP430F5152IRSBT 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 support for 32-kHz crystals (XT1) and up to 25-MHz high-frequency crystals.
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 remapping across P1–P3 and PJ ports.

FAQ
What is the maximum operating frequency of the MSP430F5152IRSBT?
The MSP430F5152IRSBT supports a maximum system clock (MCLK) frequency of 25 MHz using an external crystal oscillator (XT1). Its digitally controlled oscillator (DCO) is calibrated to deliver stable operation across voltage and temperature ranges, enabling reliable high-speed execution while maintaining ultra-low-power characteristics essential for the MSP430F5152IRSBT's target applications.
Does the MSP430F5152IRSBT support hardware UART auto-baud rate detection?
Yes, the MSP430F5152IRSBT's USCI_A0 module supports enhanced UART with automatic baud-rate detection. This feature allows the MSP430F5152IRSBT to synchronize with incoming asynchronous serial streams without prior knowledge of the transmitter's baud rate - simplifying interoperability in heterogeneous sensor networks and reducing firmware configuration overhead.
How many ADC input channels does the MSP430F5152IRSBT support?
The MSP430F5152IRSBT supports up to 8 external analog input channels (A0–A5, A7–A8) plus 2 internal channels (including the temperature sensor), as confirmed in the device comparison table and signal descriptions. This 10-channel ADC configuration is identical to the MSP430F5172IRSBT but excludes the VREF+ and VREF− pins used only in higher-tier variants.
Is the MSP430F5152IRSBT pin-compatible with other packages in the MSP430F51x2 family?
No - the MSP430F5152IRSBT uses the 40-pin RSB (WQFN) package. While functionally identical to the 40-pin YFF (DSBGA) variant, it is not pin-compatible with the 38-pin DA (TSSOP) package due to differing pin counts and signal allocations. Board layout must be specific to the RSB footprint for the MSP430F5152IRSBT.
What debug interface does the MSP430F5152IRSBT use?
The MSP430F5152IRSBT uses the Spy-Bi-Wire (SBW) interface via the RST/NMI/SBWTDIO and TEST/SBWTCK pins - a 2-wire subset of JTAG. This interface supports full in-system programming, real-time debugging, and flash memory erase/write operations without requiring a 4-pin JTAG header, reducing PCB footprint and BOM cost for the MSP430F5152IRSBT.
