Product details
Overview
MSP430F2111TRGER from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller featuring 2KB flash, 128B RAM, integrated Comparator_A+, Timer_A3 with three capture/compare registers, and a digitally controlled oscillator (DCO) calibrated to ±1% at 1 MHz–16 MHz. It operates from 1.8 V to 3.6 V and supports sub-1 µs wake-up from standby mode - ideal for battery-powered sensor nodes and portable measurement systems.
For engineers reviewing the MSP430F2111TRGER datasheet, MSP430F2111TRGER pinout, MSP430F2111TRGER application, or MSP430F2111TRGER equivalent, key selection criteria include its 20-pin TSSOP (PW) package, -40°C to 105°C extended temperature rating, ultra-low active current (250 µA @ 1 MHz, 2.2 V), brownout detection, and on-chip emulation for debug via JTAG.
Technical Context
The MSP430F2111TRGER implements a 16-bit CPU with constant generators and seven addressing modes, enabling single-cycle register operations and high code efficiency. Its basic clock module delivers ACLK, MCLK, and SMCLK from internal DCO (up to 16 MHz), 32-kHz crystal, or external high-frequency source.
Peripheral integration includes a 16-bit Timer_A3 with three independent capture/compare registers supporting PWM, interval timing, and event counting; an analog comparator with eight selectable inputs (CA0–CA7) enabling slope ADC functionality; and dual 8-bit I/O ports (P1/P2) with individually configurable pullup/down resistors and edge-selectable interrupts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | 16-bit RISC CPU with 16 registers and 62.5-ns instruction cycle time - enables deterministic real-time control and compact firmware footprint. |
| Memory | 2KB + 256B flash (main + info memory) and 128B RAM - sufficient for standalone sensor firmware with calibration data storage in segment A. |
| Supply Voltage | 1.8 V to 3.6 V - compatible with single-cell Li-ion, coin-cell, or regulated 3.3 V rails without level-shifting. |
| Ultra-Low Power | Active mode: 250 µA @ 1 MHz, 2.2 V; LPM4 (RAM retention): 0.1 µA - extends battery life in intermittent-sampling applications beyond 10 years. |
| Wake-Up Time | <1 µs from standby mode - critical for responsive wake-on-event designs like motion-triggered sensors or RF listen-before-talk systems. |
| Temperature Range | -40°C to +105°C - qualified for industrial and automotive under-hood environments where thermal stability is required. |
| DCO Accuracy | Four factory-calibrated frequencies (1/8/12/16 MHz) with ±1% tolerance - eliminates need for external crystal in cost-sensitive timing-critical applications. |
Pinout & Package
The MSP430F2111TRGER is packaged in a 20-pin plastic thin shrink small-outline package (TSSOP, PW), with exposed pad not present. Pin functions are validated per TI SLAS439F Rev. F (2011), Table 2 and Figure 2 (PW top view).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P1.0/TACLK | Timer_A clock input / general I/O | Accepts external timing signal for synchronous capture or provides gated clock output to peripherals. |
| P1.1/TA0/TDI/TCLK | Timer_A compare output / JTAG test interface | Dual-use pin: drives TA0 PWM or serves as JTAG TDI/TCLK during programming and debug. |
| P1.2/TA1 | Timer_A compare output / general I/O | Provides second PWM channel or GPIO with interrupt capability for push-button or status signaling. |
| P1.3/TA2 | Timer_A compare output / general I/O | Third independent PWM output or interrupt-capable input for sensor trigger or fault detection. |
| P1.4/SMCLK/TCK | Sub-main clock output / JTAG test clock | Exposes SMCLK for synchronization with external logic or acts as JTAG TCK during boundary scan. |
| P2.0/ACLK/CA2 | ACLK output / comparator input | Drives low-frequency clock to RTC peripherals or selects CA2 as analog input for voltage monitoring. |
| XIN/P2.6/CA6 | Crystal oscillator input / comparator input | Connects to 32-kHz watch crystal for precise timing or routes CA6 as analog reference input. |
| RST/NMI | Reset / non-maskable interrupt | Hardware reset initiation or high-priority event handling (e.g., power-fail detection). |
| TEST | JTAG test mode select | Enables JTAG interface when pulled high; connects to device protection fuse for security lock. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip emulation module (EEM) | Enables full-speed debugging, breakpoint setting, and flash programming via JTAG without external probes - reduces development cycle time. |
| Bootstrap loader (BSL) | Allows field firmware updates over UART using P1.1 (TX) and P2.2 (RX), secured by user-defined password and BSLKEY register - eliminates need for JTAG hardware in production. |
| Comparator_A+ with slope ADC | Converts analog signals (e.g., thermistor, battery voltage) to digital values using timer-driven ramp comparison - removes need for external ADC in simple monitoring applications. |
| Brownout detector | Generates automatic reset if VCC drops below programmable threshold - prevents erratic operation during battery depletion or supply transients. |
| Five low-power modes (LPM0–LPM4) | Supports hierarchical power management: LPM3 retains ACLK for RTC while drawing only 0.7 µA; LPM4 shuts down all clocks for 0.1 µA standby - maximizes energy budget allocation. |
Applications
| Wireless Sensor Node | Battery-Powered Data Logger |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F2112TRGER | Same package and core, but adds 10-bit SAR ADC (6 channels) and USI (SPI/I2C) - no comparator slope ADC support. | Preferred for designs requiring higher-resolution analog digitization and standard serial interfaces instead of comparator-based A/D. | Select when ADC resolution > comparator slope method is needed and SPI/I2C connectivity is mandatory. |
| MSP430G2553IPW20R | Lower-cost G-series variant: 16KB flash, 512B RAM, same 20-pin TSSOP, but lacks factory DCO calibration and has higher active current (270 µA @ 1 MHz). | Suitable for cost-sensitive, non-temperature-critical applications where extended qualification and tighter DCO tolerance are unnecessary. | Choose for prototyping or high-volume consumer devices where 105°C rating and ±1% DCO are not required. |
Compared with MSP430F2112TRGER and MSP430G2553IPW20R, the MSP430F2111TRGER uniquely balances ultra-low standby power (0.1 µA), factory-trimmed DCO accuracy, and comparator-based analog sensing - making it optimal for long-life, crystal-free, analog-intensive embedded endpoints.

FAQ
What is the maximum operating frequency of the MSP430F2111TRGER?
The MSP430F2111TRGER supports a maximum system clock (MCLK) frequency of 16 MHz when VCC ≥3.3 V, with factory-calibrated DCO settings at 1 MHz, 8 MHz, 12 MHz, and 16 MHz achieving ±1% accuracy. At lower supply voltages (e.g., 1.8 V), the maximum reliable frequency is reduced to 6 MHz per TI's recommended operating conditions.
Does the MSP430F2111TRGER include a hardware ADC?
No, the MSP430F2111TRGER does not contain a dedicated SAR or sigma-delta ADC. Instead, it integrates Comparator_A+ with Timer_A3 to implement slope analog-to-digital conversion - using the comparator output to gate a timer counting against a known ramp, yielding up to 12-bit effective resolution depending on timing stability and noise.
What debug interface does the MSP430F2111TRGER support?
The MSP430F2111TRGER supports JTAG-based debugging and programming via its dedicated TEST, TCK, TMS, TDI, and TDO pins (mapped to P1.4–P1.7 and TEST). It also includes an on-chip emulation module (EEM) enabling full-speed breakpoints, register inspection, and flash programming without external debug probes.
How is flash memory protected on the MSP430F2111TRGER?
Flash protection on the MSP430F2111TRGER is enforced via a security fuse that disables JTAG access when blown. Additionally, the bootstrap loader (BSL) can be disabled by writing 0xAA55 to address 0xFFDE, and flash erasure during BSL access is prevented by writing 0x0000 to the same location - providing layered firmware security for production units.
Is the MSP430F2111TRGER pin-compatible with other MSP430F21x1 variants?
Yes, the MSP430F2111TRGER shares identical pinout and package (20-pin TSSOP) with all members of the MSP430F21x1 family including MSP430F2101TRGER, MSP430F2121TRGER, and MSP430F2131TRGER - enabling hardware reuse across memory-size variants while maintaining identical peripheral mappings and electrical characteristics.
