概要

Description

The MSP430G2231IRSA16R is a member of TI’s MSP430G2xx ultra‑low‑power microcontroller family. It’s a small, 16‑bit RISC MCU designed for low‑cost, battery‑powered embedded tasks. Key points:
- On‑chip memory: a few kilobytes of flash for code and a modest amount of RAM.
- Clock/power: built‑in clock system (DCO) and multiple low‑power modes for long battery life.
- Peripherals: timers, basic analog capabilities (such as an ADC/comparator on many G2x parts), a serial communications block for UART/SPI/I2C (USCI), GPIO, and a watchdog timer.
- Package: the IRSA16R suffix indicates a 16‑pin package (RoHS/tape‑and‑reel variant).
Typical uses include simple sensors, remote controls, timers, small controllers, and other low‑power applications where cost and size matter. For exact memory size, peripheral count, voltage range (roughly 1.8–3.6 V), and speed, consult the specific datasheet and device package documentation.

Features

Key features of MSP430G2231IRSA16R (16-pin package):
- 16-bit MSP430 microcontroller with RISC architecture; no external clock required
- Memory: 2 KB Flash, 128 bytes RAM; in-system programmable
- Clock: Internal DCO clock, up to about 1 MHz (calibration options)
- Peripherals: USCI_A0 UART, 16-bit Timer_A with capture/compare, Watchdog Timer, Basic Timer
- I/O: up to ~11 general-purpose I/O pins in the 16-pin package
- Power: 2.0–3.6 V operating range
- Low-power design: multiple low-power modes (LPM0–LPM4) for sleep currents
- Reset/supervision: Power-on reset and Brown-out reset
- Debug/programming: In-system programming via SBW (Spy-Bi-Wire)
- Temperature range: -40°C to +85°C (industrial)
Notes: This device emphasizes low pin count with basic timer/UART peripherals, suitable for simple, energy-efficient applications with embedded serial communication.
