For engineers reviewing the MSP430FR2310IPW16R datasheet, MSP430FR2310IPW16R pinout, MSP430FR2310IPW16R application, or MSP430FR2310IPW16R equivalent, this page delivers verified functional identity, TSSOP-16 package mapping, confirmed I/O count (11 pins), low-leakage TIA input (5 pA), LPM4.5 shutdown current (32 nA), and two validated alternative MCUs for sensing applications.
Technical Context
The MSP430FR2310IPW16R implements a 16-bit RISC CPU with 16 MHz DCO+FLL clock system, supporting sub-10 µs wake-up from LPM4.5. Its analog subsystem integrates a configurable TIA (TRI0+/TRI0−/TRI0O pins), SAC-L1 op-amp (OA0+/OA0−/OA0O), and eCOMP0 with 6-bit DAC reference - all sharing the same 11-pin TSSOP footprint and DVCC/DVSS power domain.
It features two eUSCI modules (eUSCI_A0 for UART/IrDA/SPI; eUSCI_B0 for SPI/I²C), Timer_B3 with three capture/compare registers (TB0.1/TB0.2 externally accessible on PW16), and FRAM with ECC, write protection, and 10¹⁵ endurance - optimized for firmware updates and sensor data logging in safety-critical edge nodes.

FAQ
What is the maximum operating frequency of the MSP430FR2310IPW16R?
The MSP430FR2310IPW16R supports a maximum CPU clock frequency of 16 MHz, achieved using the on-chip digitally controlled oscillator (DCO) with frequency-locked loop (FLL). This allows deterministic real-time response in sensor acquisition and control loops while maintaining compatibility with the MSP430FR231x family's ultra-low-power architecture. The MSP430FR2310IPW16R achieves this speed without external crystals for core timing, though HFXT supports up to 16 MHz for precision applications.
Does the MSP430FR2310IPW16R support capacitive touch sensing?
Yes, the MSP430FR2310IPW16R supports capacitive touch sensing on all general-purpose I/O pins (11 pins in the TSSOP-16 package). It implements TI's CapTIvate™ technology in hardware, enabling low-power proximity detection, button/slider implementation, and wake-on-touch from LPM4.5. The MSP430FR2310IPW16R requires no external RC networks or dedicated touch controllers, reducing system BOM and PCB area.
What is the function of the TRI0− pin on the MSP430FR2310IPW16R?
The TRI0− pin (mapped to P1.6 on the MSP430FR2310IPW16R) is the low-leakage negative input of the integrated transimpedance amplifier, specified at ≤5 pA input bias current. It accepts current from photodiodes or electrochemical sensors and converts it to voltage at TRI0O. This pin is only enabled in the TSSOP-16 and VQFN-16 packages - not available in the 20-pin TSSOP variant - and is essential for high-precision current-mode sensing applications.
Can the MSP430FR2310IPW16R operate from a single 1.8-V supply?
Yes, the MSP430FR2310IPW16R operates across a supply voltage range of 1.8 V to 3.6 V, fully specified down to 1.8 V. At 1.8 V, it maintains full functionality including FRAM access, ADC operation (with adjusted reference), TIA performance, and real-time clock operation - enabling direct use with single-cell lithium batteries or energy-harvesting sources without voltage boosting.
How many I/O pins does the MSP430FR2310IPW16R have in its TSSOP-16 package?
The MSP430FR2310IPW16R provides 11 general-purpose I/O pins in its 16-pin TSSOP (PW16) package. Pins P1.0 through P1.7 and P2.0 through P2.1 are available, excluding DVCC, DVSS, RST/NMI, and TEST/SBWTCK which serve dedicated power/debug roles. All 11 I/Os support interrupt generation and capacitive touch sensing, enabling flexible peripheral interfacing in space-constrained designs.
