Product details
Overview
MSP430FR2310IPW16 from Texas Instruments is a 16-pin TSSOP ultra-low-power mixed-signal microcontroller featuring a 16-bit RISC CPU, 2KB FRAM, 1KB RAM, integrated transimpedance amplifier (TIA) with 5 pA input leakage, 8-channel 10-bit ADC (200 ksps), and dual eUSCI modules supporting UART/I²C/SPI - deployed in smoke detectors and portable health sensors.
For engineers reviewing the MSP430FR2310IPW16 datasheet, MSP430FR2310IPW16 pinout, MSP430FR2310IPW16 application, or MSP430FR2310IPW16 equivalent, this page delivers verified functional architecture, low-power mode current values (LPM4.5 = 32 nA), TIA input/output configuration, FRAM endurance (10¹⁵ cycles), and precise I/O mapping for 11-pin TSSOP-16 layout integration.
Technical Context
The MSP430FR2310IPW16 implements a digitally controlled oscillator (DCO) with FLL, ±1% accuracy at room temperature, and supports multiple clock sources including internal REFO (32 kHz), VLO (10 kHz), MODOSC, and external crystals up to 16 MHz. Its LPM3.5 mode enables RTC operation with 0.71 µA draw using a 32.768-kHz crystal while retaining backup memory functionality.
It integrates three key analog blocks on-die: a configurable TIA (TRI0) with half-rail input and rail-to-rail output, a smart analog combo (SAC-L1) operating as a general-purpose op amp, and an enhanced comparator (eCOMP0) with 6-bit DAC reference and programmable hysteresis - all independently configurable for high- or low-power operation.

FAQ
What is the maximum operating frequency of the MSP430FR2310IPW16 CPU core?
The MSP430FR2310IPW16 CPU operates at up to 16 MHz using its digitally controlled oscillator (DCO) with frequency-locked loop (FLL). This speed is achievable across the full 1.8–3.6 V supply range and enables sub-10 µs wake-up from LPM3.5 to active mode. The MSP430FR2310IPW16 maintains consistent timing performance due to on-chip calibration and ±1% DCO accuracy at room temperature.
Does the MSP430FR2310IPW16 support capacitive touch sensing on all I/O pins?
Yes, all 11 GPIOs of the MSP430FR2310IPW16 support capacitive touch sensing. This capability is implemented in hardware via the built-in capacitive touch I/O circuitry and does not require external components. Firmware configuration through the port registers enables each pin to operate in touch mode, making the MSP430FR2310IPW16 suitable for button, slider, or proximity interfaces in space-constrained designs.
What is the TIA input leakage specification for the MSP430FR2310IPW16?
The MSP430FR2310IPW16 specifies 5 pA typical input leakage for its transimpedance amplifier (TIA) - but only in the TSSOP-16 (PW16) package. This value is confirmed in the device's production datasheet revision December 2019 and applies specifically to pins TRI0+ (P1.7) and TRI0− (P1.6/P1.2). It enables high-fidelity photodiode current measurement in smoke detection and optical biosensing applications.
How much FRAM and RAM does the MSP430FR2310IPW16 include?
The MSP430FR2310IPW16 integrates 2 KB of ferroelectric RAM (FRAM) for program code and data storage, plus 1 KB of SRAM for runtime variables and stack operations. The FRAM includes built-in error correction code (ECC), configurable write protection, and 10¹⁵ write cycle endurance - significantly exceeding flash-based alternatives and eliminating wear-leveling overhead in logging applications.
Which low-power modes are supported by the MSP430FR2310IPW16 and what are their current draws?
The MSP430FR2310IPW16 supports six low-power modes (LPM0–LPM4.5). Key draws at 3 V include: LPM3.5 (RTC + 32B backup RAM) = 0.71 µA; LPM4.5 (full shutdown, no SVS) = 32 nA; active mode = 126 µA/MHz. These values are production-tested and specified in the SLASE58E datasheet, enabling precise battery life estimation for always-on sensing nodes.
