Texas Instruments MSP430F5152IDA

Overview

MSP430F5152IDA from Texas Instruments is a 16-bit ultra-low-power mixed-signal microcontroller in 38-pin TSSOP (DA) package, featuring 16 KB Flash, 2 KB RAM, dual 16-bit Timer_D modules, 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 targets battery-powered sensor systems and digital power supplies.

For engineers reviewing the MSP430F5152IDA datasheet, MSP430F5152IDA pinout, MSP430F5152IDA application, or MSP430F5152IDA equivalent, key selection criteria include low-power operation down to 0.25 µA in LPM4.5, 5-V-tolerant I/Os with 20-mA drive strength, integrated LDO core regulation, and support for 32-kHz and up to 25-MHz crystal oscillators.

Technical Context

The MSP430F5152IDA implements a 16-bit RISC CPU with constant generators and 40-ns instruction cycle time, paired with a unified clock system including FLL, VLO, REFO, XT1 (32 kHz–25 MHz), and digitally controlled oscillator (DCO). Its flexible power management includes programmable core voltage via integrated LDO and brownout detection.

It integrates three DMA channels, hardware 32-bit multiplier, CRC16 engine, and port mapping controller enabling dynamic peripheral-to-pin remapping. The device supports wake-up from standby mode in under 5 µs and features Schmitt-trigger inputs across all general-purpose I/Os.

FAQ

What is the maximum operating frequency of the MSP430F5152IDA?

The MSP430F5152IDA supports a maximum system clock (MCLK) frequency of 25 MHz when using the high-frequency crystal oscillator (XT1) mode. Its DCO can be calibrated to achieve stable operation across the full 1.8–3.6 V supply range, and the CPU executes instructions at 40-ns intervals - enabling real-time control loops with sub-microsecond latency. The MSP430F5152IDA does not require external PLL circuitry to reach this speed.

Does the MSP430F5152IDA support hardware debugging?

Yes, the MSP430F5152IDA supports hardware debugging via its integrated Spy-Bi-Wire (SBW) interface using the RST/NMI/SBWTDIO and TEST/SBWTCK pins. This two-wire interface enables full JTAG-like functionality - including breakpoints, register inspection, and flash programming - without requiring a 4-pin JTAG header. The MSP430F5152IDA is compatible with TI's MSP-FET and third-party SBW debug probes.

How many ADC input channels does the MSP430F5152IDA have?

The MSP430F5152IDA includes a 10-bit ADC10_A module with 8 external analog input channels (A0–A5, plus two additional pins configurable as A6/A7) and 2 internal channels (temperature sensor and VCC/2 reference). Unlike the MSP430F5172IDA, it does not support VREF+ and VREF− pins on P3.5/P3.6. All ADC inputs are accessible through P1.x and P3.x pins, and autoscan mode allows sequential conversion without CPU intervention.

Is the MSP430F5152IDA pin-compatible with other devices in the MSP430F51x2 family?

Yes, the MSP430F5152IDA shares identical pinout and package dimensions with MSP430F5172IDA and MSP430F5132IDA in the 38-pin TSSOP (DA) variant. All three devices use the same signal mapping on each pin, allowing direct PCB-level substitution where Flash/RAM or ADC channel count differences are acceptable. However, firmware must be validated for memory size and peripheral availability - e.g., MSP430F5132IDA lacks internal ADC channels and temperature sensor.

What power supply configurations does the MSP430F5152IDA support?

The MSP430F5152IDA supports single-supply operation from 1.8 V to 3.6 V on DVCC, with separate DVIO rail for 5-V-tolerant I/Os. It integrates an on-chip LDO that generates regulated VCORE from DVCC, programmable in 0.1-V steps between 1.8 V and 3.6 V. AVCC and AVSS must be decoupled independently for ADC stability, and DVSS/AVSS are internally connected but recommended to be externally tied with low-inductance path. The MSP430F5152IDA requires no external voltage regulators for core operation.
