Product details
Overview
MSP430FR2310IPW20R from Texas Instruments is a 16-bit FRAM microcontroller with 2KB program memory, 1KB RAM, integrated transimpedance amplifier (TIA), 8-channel 10-bit ADC, and smart analog combo (SAC-L1) for sensor signal conditioning. It operates from 1.8 V to 3.6 V, achieves 126 µA/MHz active current, and supports ultra-low-power modes including 32 nA shutdown (LPM4.5), targeting smoke detectors and portable health devices.
For engineers reviewing the MSP430FR2310IPW20R datasheet, MSP430FR2310IPW20R pinout, MSP430FR2310IPW20R application, or MSP430FR2310IPW20R equivalent, key selection criteria include TIA input leakage (5 pA), FRAM endurance (10¹⁵ cycles), capacitive touch I/O support, 20-pin TSSOP package compatibility, and dual USCI modules for UART/I²C/SPI in battery-constrained sensing systems.
Technical Context
The MSP430FR2310IPW20R implements a 16-bit RISC CPU with 16 MHz DCO+FLL clock system, ±1% accuracy at room temperature, and sub-10 µs wake-up from LPMs. Its analog subsystem integrates a configurable TIA (TRI0+/TRI0−/TRI0O pins), SAC-L1 op-amp (OA0±/OA0O), and eCOMP0 with 6-bit DAC reference - all sharing rail-to-rail I/O and low-power/high-power mode selection.
Digital peripherals include two Timer_B3 modules (each with three capture/compare registers), RTC counter in LPM3.5, CRC16 engine, and enhanced USCI_A0 (UART/IrDA/SPI) and USCI_B0 (SPI/I²C with remap). All 16 GPIOs support capacitive touch, interrupt wake-up, and multiplexed analog functions across P1 and P2 ports.

FAQ
What is the maximum operating frequency of the MSP430FR2310IPW20R CPU?
The MSP430FR2310IPW20R features a 16-bit RISC CPU with a digitally controlled oscillator (DCO) that supports up to 16 MHz operation, achieving ±1% accuracy at room temperature when locked to the on-chip reference. This frequency enables real-time sensor processing while maintaining sub-10 µs wake-up from low-power modes - critical for duty-cycled applications like smoke detection where responsiveness and battery life must coexist. The MSP430FR2310IPW20R's architecture ensures deterministic timing without PLL complexity.
Does the MSP430FR2310IPW20R support capacitive touch sensing on all I/O pins?
Yes, the MSP430FR2310IPW20R supports capacitive touch sensing on all 16 general-purpose I/O pins without external components, leveraging its integrated CS (Capacitive Sensing) hardware module and dedicated firmware libraries in MSP430Ware. This capability is confirmed in the device overview and functional block diagram, and applies specifically to the PW20 package variant. The MSP430FR2310IPW20R's touch I/O implementation delivers robust noise immunity and low power consumption - ideal for consumer wearables and interactive safety devices.
What is the function of the TRI0+ and TRI0− pins on the MSP430FR2310IPW20R?
The TRI0+ and TRI0− pins on the MSP430FR2310IPW20R are the positive and negative input terminals of the integrated transimpedance amplifier (TIA), designated as P1.7 and P1.6 respectively. They enable direct connection of current-output sensors such as photodiodes or electrochemical cells, converting nanoamp-level currents into measurable voltages with 5 pA input leakage (TSSOP-20 only). The MSP430FR2310IPW20R's TIA supports half-rail biasing, rail-to-rail output, and configurable power modes - making it essential for optical and gas-sensing applications.
Can the MSP430FR2310IPW20R operate from a single 1.8-V supply?
Yes, the MSP430FR2310IPW20R operates across a supply voltage range of 1.8 V to 3.6 V, with 1.8 V being the absolute minimum specified in the Recommended Operating Conditions table. However, the actual minimum usable voltage depends on SVS (Supply Voltage Supervisor) thresholds - if SVS is enabled, the effective lower limit may be higher. The MSP430FR2310IPW20R's ability to run at 1.8 V allows direct integration with single-cell Li-ion/LiPo batteries and coin cells, supporting multi-year operation in ultra-low-power sensing nodes.
Is the MSP430FR2310IPW20R pin-compatible with the MSP430FR2311IPW20R?
Yes, the MSP430FR2310IPW20R is fully pin-compatible with the MSP430FR2311IPW20R - both use the identical 20-pin TSSOP (PW20) package, share identical pin functions, electrical characteristics, and peripheral mappings. The only functional difference is FRAM size (2 KB vs. 3.75 KB); all analog blocks (TIA, SAC-L1, eCOMP), timers, USCI modules, and I/O capabilities are identical. This allows drop-in replacement during design iteration or volume production without PCB changes - a verified compatibility documented in TI's Device Comparison table.
