Product details
Overview
MSP430FR2310IRGYT from Texas Instruments is a 16-bit FRAM microcontroller with integrated transimpedance amplifier (TIA), 10-bit ADC, smart analog combo (SAC-L1), and ultra-low-power operation-featuring 2KB FRAM, 1KB RAM, 12 I/Os in 16-pin VQFN, and active current of 126 µA/MHz at 3 V for smoke detector and portable health sensor applications.
For engineers reviewing the MSP430FR2310IRGYT datasheet, MSP430FR2310IRGYT pinout, MSP430FR2310IRGYT application, or MSP430FR2310IRGYT equivalent, this page delivers verified technical context, package-validated pin functions, real-world use cases, and two confirmed alternative parts for sensing-focused embedded designs requiring sub-µA standby and analog signal conditioning.
Technical Context
The MSP430FR2310IRGYT implements a 16-bit RISC CPU with DCO-based clock system (±1% accuracy at room temperature), supporting LPM3.5 (0.71 µA with RTC + 32.768-kHz crystal) and LPM4.5 (32 nA shutdown). Its analog subsystem includes a configurable TIA with 5 pA input leakage (enabled only on TSSOP16 per datasheet), rail-to-rail output, and half-rail input-paired with an 8-channel 10-bit ADC (200 ksps, internal 1.5-V reference) and SAC-L1 op-amp.
Digital peripherals include two Timer_B3 modules (each with three capture/compare registers), eUSCI_A0 (UART/IrDA/SPI) and eUSCI_B0 (SPI/I²C), CRC16 engine, and JTAG/Spy-Bi-Wire debug interface. FRAM memory (2KB program + unified storage) provides 10¹⁵ write endurance, ECC protection, and no erase-before-write latency.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller-with-analog-peripherals applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430FR2311IRGY | 3.75 KB FRAM, same 12-pin VQFN package, identical peripherals and pinout. | Higher program memory enables more complex sensor fusion algorithms or BLE stack integration. | Select when firmware size exceeds 2 KB or future scalability is required; drop-in replacement with no layout change. |
| MSP430FR2111IPW16 | 2 KB FRAM, 16-pin TSSOP, no TIA; includes enhanced comparator and 16-bit timer but lacks SAC-L1 and eUSCI_B. | Targeted at simpler analog threshold detection (e.g., basic smoke alarm), not current-to-voltage conversion. | Choose for cost-sensitive, non-TIA applications where TSSOP assembly is preferred; not pin-compatible with RGY package. |

FAQ
What is the maximum operating frequency of the MSP430FR2310IRGYT?
The MSP430FR2310IRGYT features a digitally controlled oscillator (DCO) rated up to 16 MHz, with ±1% accuracy at room temperature when calibrated against the on-chip reference. This allows deterministic real-time execution for time-critical sensor sampling and communication tasks without external crystals in many applications.
Does the MSP430FR2310IRGYT support hardware UART communication?
Yes, the MSP430FR2310IRGYT includes eUSCI_A0, which supports UART mode with full-duplex operation, programmable baud rates, and automatic LIN break detection. It uses P1.5 (UCA0TXD) and P1.6 (UCA0RXD) pins in the RGY package, enabling robust serial communication for debugging or host interface.
Can the transimpedance amplifier (TIA) in the MSP430FR2310IRGYT be used in the VQFN package?
Yes, the TIA0 module is functionally present in the MSP430FR2310IRGYT (RGY package), with dedicated pins TRI0+ (P1.7), TRI0− (P1.6), and TRI0O (P1.5). While the 5 pA input leakage specification applies only to TSSOP16 per datasheet, the core TIA functionality-including gain configuration and output drive-is fully operational in RGY.
How much FRAM and RAM does the MSP430FR2310IRGYT have?
The MSP430FR2310IRGYT integrates 2 KB of ferroelectric RAM (FRAM) for program and data storage, plus 1 KB of SRAM for runtime variables and stack. FRAM provides flash-like nonvolatility with SRAM-like write speed and unlimited endurance-critical for logging sensor events or storing calibration data in field-deployed devices.
What low-power modes are supported by the MSP430FR2310IRGYT?
The MSP430FR2310IRGYT supports six low-power modes (LPM0–LPM4.5). Key states include LPM3.5 (0.71 µA with RTC active using 32.768-kHz crystal) and LPM4.5 (32 nA shutdown with FRAM retention), enabling multi-year operation on CR2032 batteries in applications like smoke alarms and wearable health trackers.
