Product details
Overview
MSP430FR2310IPW20 from Texas Instruments is a 16-bit FRAM microcontroller with integrated transimpedance amplifier (TIA), 2KB program FRAM, 1KB RAM, and 16 I/Os in TSSOP-20 package-designed for ultra-low-power sensing applications such as smoke detection and portable health monitoring.
For engineers reviewing the MSP430FR2310IPW20 datasheet, MSP430FR2310IPW20 pinout, MSP430FR2310IPW20 application, or MSP430FR2310IPW20 equivalent, key selection considerations include its 32 nA LPM4.5 shutdown current, TIA input leakage down to 5 pA (TSSOP only), 10-bit ADC with 200 ksps sampling, and dual eUSCI modules supporting UART/I²C/SPI.
Technical Context
The MSP430FR2310IPW20 implements a 16-bit RISC CPU with DCO-based clock system delivering ±1% accuracy at room temperature, enabling sub-10 µs wake-up from LPMs. Its analog subsystem integrates a configurable TIA (TRI0), smart analog combo (SAC-L1) op amp, and enhanced comparator with 6-bit DAC reference-each supporting high- and low-power modes.
Digital peripherals include two Timer_B3 modules (each with three capture/compare registers), RTC counter, 16-bit CRC engine, and IR modulation logic. Memory architecture unifies 2KB FRAM (10¹⁵ write endurance, ECC protected) and 1KB SRAM, with capacitive-touch-capable I/O across all 16 pins.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power sensing MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430FR2311IPW20 | 3.75KB FRAM, identical peripherals and pinout; same TSSOP-20 package and TIA specs. | Preferred where larger code space or future firmware expansion is required-no hardware change needed. | Select when >2KB program memory is needed; otherwise MSP430FR2310IPW20 offers optimal cost/performance balance. |
| MSP430FR2111IPW16 | 16-pin TSSOP, 2KB FRAM, no TIA, only 11 I/Os, single Timer_B3, no RTC counter. | Suitable for simpler sensor nodes without current-to-voltage conversion or real-time timestamping requirements. | Choose for space-constrained, lower-complexity designs where TIA and RTC are unnecessary-requires PCB redesign due to different package and pin count. |
Compared with MSP430FR2311IPW20, the MSP430FR2310IPW20 reduces FRAM capacity while retaining full analog feature set and pin compatibility-making it ideal for cost-sensitive, fixed-function sensing nodes. Versus MSP430FR2111IPW16, it adds TIA, RTC, and 5 extra I/Os at the cost of larger footprint and higher pin count.

FAQ
What is the maximum operating frequency of the MSP430FR2310IPW20?
The MSP430FR2310IPW20 features a digitally controlled oscillator (DCO) with frequency-locked loop (FLL) capable of up to 16 MHz operation. This maximum frequency is achievable across the full 1.8–3.6 V supply range and maintains ±1% accuracy at room temperature when calibrated against the on-chip reference oscillator. The MSP430FR2310IPW20 uses this clock for CPU execution, peripheral timing, and ADC sampling control.
Does the MSP430FR2310IPW20 support capacitive touch sensing on all I/O pins?
Yes, the MSP430FR2310IPW20 supports capacitive touch sensing on all 16 general-purpose I/O pins-P1.0 through P1.7 and P2.0 through P2.7. This capability is implemented in hardware without requiring external components, leveraging the built-in capacitance sensing module and dedicated firmware libraries in MSP430Ware. Each pin can be individually configured as a touch electrode in the MSP430FR2310IPW20.
What is the function of the TRI0 module in the MSP430FR2310IPW20?
The TRI0 module in the MSP430FR2310IPW20 is the transimpedance amplifier-renamed TIA0 in documentation but retained as TRI0 in register names and pin labels. It provides current-to-voltage conversion with ≤5 pA input leakage (TSSOP-20 only), rail-to-rail output, and configurable power modes. Its dedicated pins (TRI0+, TRI0−, TRI0O) appear on P1.7, P1.6, and P1.5 respectively in the MSP430FR2310IPW20.
Can the MSP430FR2310IPW20 operate from a single 1.8-V supply?
Yes, the MSP430FR2310IPW20 operates across a supply voltage range of 1.8 V to 3.6 V. At 1.8 V, it supports full functionality including CPU execution at reduced maximum frequency, ADC operation (with adjusted reference), and TIA operation-though minimum supply is constrained by SVS threshold levels. All specifications in the MSP430FR2310IPW20 datasheet are validated down to 1.8 V.
Is the MSP430FR2310IPW20 pin-compatible with the MSP430FR2311IPW20?
Yes, the MSP430FR2310IPW20 is fully pin-compatible with the MSP430FR2311IPW20 in the TSSOP-20 (PW20) package. Both share identical pin assignments, electrical characteristics, peripheral mappings, and TIA specifications-including 5 pA input leakage. The only functional difference is FRAM capacity: 2KB in MSP430FR2310IPW20 versus 3.75KB in MSP430FR2311IPW20.
