Product details
Overview
MSP430FR2110IPW16R from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller with 2KB program FRAM, 1KB RAM, 10-bit 8-channel ADC, and integrated eCOMP comparator. It operates from 1.8 V to 3.6 V, achieves 120 µA/MHz active current, and supports LPM3.5 (1 µA) and LPM4.5 (34 nA) for battery-powered smoke detectors and door/window sensors.
For engineers reviewing the MSP430FR2110IPW16R datasheet, MSP430FR2110IPW16R pinout, MSP430FR2110IPW16R application, or MSP430FR2110IPW16R equivalent, key selection criteria include FRAM endurance (1015 write cycles), capacitive touch I/O capability across all 12 pins, RTC support in deep sleep, and TSSOP-16 package compatibility with existing MSP430FR2x layouts.
Technical Context
The MSP430FR2110IPW16R integrates a 16-MHz digitally controlled oscillator (DCO) with FLL, on-chip 32-kHz REFO and 10-kHz VLO oscillators, and programmable MCLK/SMCLK prescalers. Its clock system enables sub-10 µs wake-up from LPMs and precise timing for RTC and ADC sampling.
It features Timer_B3 with three capture/compare registers (CCR0–CCR2), where CCR1 and CCR2 are externally accessible for PWM or input capture, while CCR0 serves internal period generation. The eUSCI_A module supports UART, IrDA, and SPI with configurable baud rates and automatic flow control.

FAQ
What is the maximum operating frequency of the MSP430FR2110IPW16R?
The MSP430FR2110IPW16R features a 16-MHz digitally controlled oscillator (DCO) with frequency-locked loop (FLL), enabling a maximum CPU clock frequency of 16 MHz. This speed is achievable across the full 1.8 V to 3.6 V supply range and supports real-time processing for sensor fusion and communication protocols without compromising ultra-low-power operation in active mode (120 µA/MHz).
Does the MSP430FR2110IPW16R support hardware debugging?
Yes, the MSP430FR2110IPW16R supports hardware debugging via Spy-Bi-Wire (SBW) using pins TEST (SBWTCK) and RST/NMI/SBWTDIO. It is fully compatible with the MSP-FET430U20 and MSP-TS430PW20 development tools. No external JTAG header is required - SBW uses only two pins and enables full flash programming, breakpoint setting, and real-time register inspection during development.
Can the MSP430FR2110IPW16R operate from a 1.8 V supply?
Yes, the MSP430FR2110IPW16R operates from 1.8 V to 3.6 V. At 1.8 V, it maintains full functionality including ADC operation, FRAM read/write, and real-time clock with crystal. However, minimum supply voltage is constrained by SVS threshold settings - the device's built-in supply-voltage supervisor must be configured to match the selected VCC level to prevent unintended resets during brown-out conditions.
How many analog input channels does the MSP430FR2110IPW16R have?
The MSP430FR2110IPW16R includes eight single-ended analog input channels (A0–A7), all accessible on dedicated pins in the TSSOP-16 package. These channels interface directly with the 10-bit SAR ADC, which supports up to 200 ksps sampling and integrates an internal temperature sensor and 1.5-V reference - eliminating the need for external analog front-end components in most sensing applications.
Is the MSP430FR2110IPW16R pin-compatible with other MSP430FR2x devices?
Yes, the MSP430FR2110IPW16R is pin-compatible with MSP430FR2111IPW16R, MSP430FR2100IPW16R, and MSP430FR2000IPW16R in the TSSOP-16 (PW16) package. All share identical pin functions, electrical characteristics, and footprint - enabling drop-in replacement within the same family for memory scaling or cost optimization without PCB redesign.
