Product details
Overview
MSP430G2111IN14 from Texas Instruments is an ultralow-power 16-bit mixed-signal microcontroller in a 14-pin PDIP package, featuring 1 KB Flash, 128 B RAM, one 16-bit Timer_A with two capture/compare registers, and an integrated analog comparator. It operates from 1.8 V to 3.6 V and supports five power-saving modes, enabling battery-powered sensor node applications requiring precise analog signal comparison and low-energy wake-up.
For engineers reviewing the MSP430G2111IN14 datasheet, MSP430G2111IN14 pinout, MSP430G2111IN14 application, or MSP430G2111IN14 equivalent, key selection criteria include its 10 I/O pins, comparator-based slope A/D capability, sub-1 µs wake-up from standby mode, and compatibility with Spy-Bi-Wire programming-critical for compact, cost-sensitive embedded measurement systems.
Technical Context
The MSP430G2111IN14 implements a 16-bit RISC CPU with constant generators and 16 general-purpose registers, executing instructions in 62.5 ns at 16 MHz. Its clock system integrates a digitally controlled oscillator (DCO), internal low-frequency oscillator (VLO), and external 32-kHz crystal support, delivering ACLK, SMCLK, and MCLK with configurable source routing.
It includes a dedicated Comparator_A+ module with eight selectable inputs (CA0–CA7) and CAOUT output, supporting analog threshold detection and slope-type ADC conversion. The device uses a single 8-bit port P1 (P1.0–P1.7) and two-bit port P2 (P2.6–P2.7), all with individually programmable pullup/pulldown resistors and edge-selectable interrupts.

FAQ
What is the maximum operating frequency of the MSP430G2111IN14?
The MSP430G2111IN14 supports a maximum MCLK frequency of 16 MHz when VCC ≥ 3.3 V and duty cycle is 50% ± 10%. At 2.7 V, the maximum is 12 MHz, and at 1.8 V, it is 6 MHz. These limits are defined by the DCO calibration and ensure stable execution across the full supply range. The MSP430G2111IN14 achieves this performance while maintaining ultralow active-mode current of 220 µA at 1 MHz and 2.2 V.
Does the MSP430G2111IN14 support JTAG debugging?
No, the MSP430G2111IN14 does not support full 4-wire JTAG. It uses the 2-wire Spy-Bi-Wire (SBW) interface via pins RST/NMI/SBWTDIO and TEST/SBWTCK for programming and debugging. This reduces pin count and PCB space versus JTAG while retaining full flash erase/write, breakpoint, and register inspection capabilities. The MSP430G2111IN14 implements SBW protocol natively in hardware without external level shifters.
How many I/O pins does the MSP430G2111IN14 provide?
The MSP430G2111IN14 provides ten usable I/O pins: eight from Port 1 (P1.0–P1.7) and two from Port 2 (P2.6–P2.7). All ten support digital input/output, individually programmable pullup/pulldown resistors, and edge-selectable interrupts. P2.6 and P2.7 also serve as XIN/XOUT for crystal oscillator use. The MSP430G2111IN14 does not include additional dedicated analog input pins beyond those shared with digital I/O.
What analog functions are integrated into the MSP430G2111IN14?
The MSP430G2111IN14 integrates a single Comparator_A+ module with eight selectable analog inputs (CA0–CA7), CAOUT output, and support for slope analog-to-digital conversion. It does not include ADC or DAC. The comparator operates across the full 1.8–3.6 V supply range and can be configured with internal or external references. This analog capability is exclusive to the G2x11 series - the MSP430G2111IN14 distinguishes itself from G2x01 variants by this feature.
Is the MSP430G2111IN14 pin-compatible with other devices in the MSP430G2xx family?
Yes, the MSP430G2111IN14 is pin-compatible with other 14-pin PDIP variants in the MSP430G2xx family, including MSP430G2101IN14, MSP430G2201IN14, and MSP430G2211IN14. All share identical pin numbering, power, ground, reset, debug, oscillator, and I/O assignments. Firmware and PCB layout can be reused across these parts, enabling scalable design - for example, upgrading to MSP430G2211IN14 adds 1 KB Flash and a second capture/compare register without hardware changes.
