Product details
Overview
MSP430G2152IPW14 from Texas Instruments is an ultra-low-power 16-bit RISC mixed-signal microcontroller featuring 1 kB Flash, 128 B RAM, a 10-bit 200-ksps ADC with internal reference and autoscan, one 16-bit Timer_A with three capture/compare registers, USI supporting SPI/I²C, and an on-chip analog comparator. It operates from 1.8 V to 3.6 V and targets battery-powered sensor nodes and portable measurement systems.
For engineers reviewing the MSP430G2152IPW14 datasheet, MSP430G2152IPW14 pinout, MSP430G2152IPW14 application, or MSP430G2152IPW14 equivalent, key selection criteria include its 14-pin TSSOP package, single-channel ADC10 capability, 1× TA3 timer configuration, 1× comparator channel, and Spy-Bi-Wire debug interface - all validated for low-power embedded control in space-constrained designs.
Technical Context
The MSP430G2152IPW14 implements a 16-bit CPU with seven addressing modes and 51 instructions, integrated with a basic clock module offering DCO (calibrated at 1/8/12/16 MHz), LF oscillator, and 32-kHz crystal support. Its power architecture supports five software-selectable low-power modes, including LPM4 with 0.1 µA off-mode current and sub-1 µs wake-up from standby.
Peripheral integration includes USI for synchronous serial communication (SPI/I²C), Comparator_A+ with single-channel input (CA0), and ADC10 with eight analog inputs (A0–A7), internal 1.5 V/2.5 V reference, sample-and-hold, and DMA-capable data transfer. All I/O pins support individually configurable pullup/pulldown resistors and capacitive-touch enable.

FAQ
What is the maximum ADC sampling rate supported by the MSP430G2152IPW14?
The MSP430G2152IPW14 supports a maximum ADC10 sampling rate of 200 ksps under specified conditions (VCC = 2.2 V, fADC10CLK = 5 MHz). This rate is achievable using the internal oscillator or external clock source configured via ADC10CTL1, and is documented in the SLAS722G datasheet Section 6.1. The actual sustained rate depends on reference voltage stability, input signal settling time, and firmware overhead for result handling.
Does the MSP430G2152IPW14 support hardware UART functionality?
No, the MSP430G2152IPW14 does not include a dedicated UART peripheral. It features a Universal Serial Interface (USI) module that supports SPI and I²C protocols in hardware, but UART must be implemented in firmware using Timer_A and GPIO pins. This software UART approach is commonly used in ultra-low-power designs where asynchronous serial is infrequent and timing constraints allow bit-banged implementation.
How many I/O pins are available on the MSP430G2152IPW14, and which ports do they belong to?
The MSP430G2152IPW14 provides eight programmable I/O pins: P1.0 through P1.7 (pins 2–9), plus P2.6 and P2.7 (pins 13–12). Port P2 has only two usable pins in the 14-pin TSSOP package, as confirmed in Table 1 and the PW-package pinout diagram of SLAS722G. All P1.x pins support interrupt, pullup/pulldown, and capacitive-touch enable; P2.6 and P2.7 support timer and oscillator functions.
Can the MSP430G2152IPW14 operate from a 3.3 V supply, and what is its minimum operating voltage?
Yes, the MSP430G2152IPW14 operates across a supply range of 1.8 V to 3.6 V, fully supporting standard 3.3 V systems. Its minimum operating voltage is 1.8 V - verified in the Absolute Maximum Ratings and Recommended Operating Conditions tables of SLAS722G. At 1.8 V, the DCO frequency is reduced, and maximum CPU speed is limited to approximately 1 MHz, but all peripherals including ADC10 and USI remain functional.
Is the MSP430G2152IPW14 pin-compatible with other devices in the MSP430G2x52 family?
Yes, the MSP430G2152IPW14 shares identical pinout and electrical characteristics with other 14-pin TSSOP variants in the MSP430G2x52 family (e.g., MSP430G2252IPW14, MSP430G2352IPW14), as confirmed in Table 1 and the PW-package diagrams of SLAS722G. This allows direct substitution within the same package footprint when upgrading Flash/RAM or ADC channel count - provided firmware accounts for differences in memory size and peripheral configuration.
