ombining the increased memory resources and integrated capacitive touch IOs on the MSP430G2xx5 devices, developers can implement more sophisticated capacitive touch capabilities like swipe, gesturing, double tap and proximity effects within their applications. Developers can also add reliable high bit-rate serial communications to designs by taking advantage of the G2xx4 and G2xx5 microcontrollers' high-frequency crystal input, another first for the MSP430 Value Line. For design flexibility within space-constrained applications, the new devices will be available in the MSP portfolio's smallest package, die-sized ball grid array (DSBGA). Additionally, MSP430G2xx4 and G2xx5 devices provide more GPIOs, timers and serial ports to ensure developers do not sacrifice performance for cost.
MSP430 LaunchPad and software support for MSP430G2xx4 and G2xx5 microcontrollers
MSP430G2xx4 and G2xx5 microcontrollers are backed by free software resources, including the MSP430 capacitive touch sense library supporting buttons, sliders, wheels and proximity sensing, Grace software, MSP430Ware, ULP Advisor and Energia, a community-driven, open-source development platform, as well as TI's broad third party support network. Existing MSP430 LaunchPad users will also be able to take advantage of the expanded memory and IO capabilities of G2xx4 devices with a new MSP430 LaunchPad expansion board available in May.
Key features and benefits of MSP430G2xx4 and G2xx5 microcontrollers
-Increased memory of 32kB/56kB Flash (G2xx4/G2xx5) and up to 8x more SRAM (4kB) while providing up to 50 percent greater code density compared to standard 8-bit microcontrollers
-Various package options, including DIP, TSSOP, QFN and DSBGA, for design flexibility
-Support for high frequency, low parts per million (PPM) external crystal for achieving <0.1 percent clock source accuracy for reliable high bit-rate serial communications
-Standby power of 1uA and fast wake-up time of < 1us for ultra-low-power consumption
-Integrated intelligent peripherals, such as 10-bit analog-to-digital converters (ADCs), UART, comparator and serial communication, offload CPU tasks for increased power efficiency
-MSP430 LaunchPad support with expansion board for MSP430G2xx4 devices, enabling access to TI's growing MCU LaunchPad and BoosterPack ecosystem
-Supported by free, downloadable software debuggers and compilers, including Code Composer Studio integrated development environment (IDE), IAR Embedded Workbench and open source MSPGCC GNU
