Product details
Overview
MSP430FR2310IRGYR from Texas Instruments is a 16-bit FRAM microcontroller with integrated transimpedance amplifier (TIA), 2KB program FRAM, 1KB RAM, and 12 I/Os in a 16-pin VQFN package. It operates from 1.8 V to 3.6 V, delivers 126 µA/MHz active current, supports LPM3.5 RTC operation at 0.71 µA, and targets ultra-low-power sensing applications such as smoke detection and portable health monitoring.
For engineers reviewing the MSP430FR2310IRGYR datasheet, MSP430FR2310IRGYR pinout, MSP430FR2310IRGYR application, or MSP430FR2310IRGYR equivalent, key selection criteria include TIA input leakage (5 pA), 10-bit ADC sampling rate (200 ksps), FRAM endurance (10¹⁵ cycles), low-power mode timing (LPM4.5 shutdown at 32 nA), and VQFN-16 package compatibility with capacitive touch I/O support.
Technical Context
The MSP430FR2310IRGYR implements a 16-bit RISC CPU with DCO-based clock system (±1% accuracy at room temperature), supporting MCLK up to 16 MHz and configurable SMCLK prescalers. Its analog subsystem integrates a dedicated TIA with half-rail input, rail-to-rail output, and selectable high/low-power modes - enabled only on TSSOP-16 and VQFN-16 packages per datasheet specification.
Digital peripherals include two Timer_B3 modules (each with three capture/compare registers), eUSCI_A0 (UART/IrDA/SPI) and eUSCI_B0 (SPI/I²C), 16-bit CRC, and RTC counter. Memory architecture unifies 2KB FRAM for code/constants/storage with ECC protection and 32-byte backup memory retained in LPM3.5.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430FR2311IRGY | 3.75KB FRAM, same package/peripherals; adds 1.75KB program memory and identical TIA/ADC specs. | Preferred where firmware complexity or data logging depth exceeds 2KB capacity. | Select MSP430FR2311IRGY when additional FRAM is required for larger algorithms or extended buffer storage. |

FAQ
What is the maximum operating frequency of the MSP430FR2310IRGYR CPU?
The MSP430FR2310IRGYR CPU operates at up to 16 MHz using its digitally controlled oscillator (DCO) with FLL stabilization. This frequency is achievable across the full 1.8 V to 3.6 V supply range and maintains ±1% accuracy at room temperature when referenced to the internal REFO oscillator. The MSP430FR2310IRGYR does not require external crystals for basic operation, though HFXT supports up to 16 MHz for higher precision timing.
Does the MSP430FR2310IRGYR support capacitive touch sensing on all I/O pins?
Yes, the MSP430FR2310IRGYR supports capacitive touch sensing on all 12 general-purpose I/O pins (P1.0–P1.7 and P2.0–P2.1). This capability is implemented via the built-in CapTIvate™-compatible peripheral and requires no external components. The MSP430FR2310IRGYR's hardware-accelerated CSD engine reduces CPU load during touch scanning, enabling low-power wake-on-touch functionality in LPM3 or deeper sleep modes.
What is the function of the TRI0+ and TRI0− pins on the MSP430FR2310IRGYR?
The TRI0+ and TRI0− pins on the MSP430FR2310IRGYR are the differential input terminals of the integrated transimpedance amplifier (TIA), used for converting low-level current signals (e.g., from photodiodes) into measurable voltages. These pins support half-rail input operation and exhibit 5 pA typical input leakage - a specification confirmed for the RGY package. The TIA output (TRI0O) is routed to P1.5 and can be digitized directly by the 10-bit ADC.
Can the MSP430FR2310IRGYR operate in real-time clock mode while powered down to LPM4.5?
No - the MSP430FR2310IRGYR cannot run the RTC in LPM4.5. In LPM4.5 (32 nA shutdown), only the 32-byte backup memory remains powered; the RTC counter is disabled. Real-time clock functionality is available in LPM3.5 (0.71 µA), where the RTC counter and backup memory remain active using a 32.768-kHz crystal. The MSP430FR2310IRGYR's LPM3.5 mode is the lowest-power state retaining timekeeping capability.
Is the MSP430FR2310IRGYR pin-compatible with the MSP430FR2311IRGY?
Yes, the MSP430FR2310IRGYR is pin-compatible with the MSP430FR2311IRGY in the 16-pin VQFN (RGY) package. Both share identical pin assignments, electrical characteristics, and peripheral mappings - including TIA, SAC, ADC, and timer functions. Firmware developed for MSP430FR2310IRGYR runs unchanged on MSP430FR2311IRGY, with the only functional difference being the increase from 2KB to 3.75KB of FRAM memory.
