Larger memory, more GPIOs for TI's MSP430 MCUs

March 27, 2013 // By Graham Prophet
New MSP430G2xx4 and G2xx5 devices from Texas Instruments enable wireless and advanced capacitive touch capabilities with additional serial ports, timers and die-sized packages.

TI has grown the MSP430 Value Line microcontroller series with new G2xx4 and G2xx5 devices. These new devices offer a code-compatible upgrade path for TI’s MSP430 Value Line series, expanding memory from 16 kB up to 56 kB Flash and up to 4 kB SRAM, enabling you to migrate existing solutions and support connectivity protocols such as wireless MBUS and near field communications (NFC).

By combining the increased memory resources and integrated capacitive touch IOs on the MSP430G2xx5 devices, you can implement more sophisticated capacitive touch capabilities such as swipe, gesturing, double tap and proximity effects within their applications. Up to 50% greater code density compared to standard 8-bit microcontrollers is possible, TI says. Standby power is 1µA and fast wake-up time of < 1µsec gives low-power consumption. Integrated intelligent peripherals, such as 10-bit analogue-to-digital converters (ADCs), UART, comparator and serial communication, offload CPU tasks for increased power efficiency. You can also add reliable high bit-rate serial communications to designs with the G2xx4 and G2xx5 microcontrollers’ high-frequency crystal input, another first for the MSP430 Value Line; high frequency, low parts per million (PPM) external crystals achieve <0.1% clock source accuracy.

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.

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.

Availability and Pricing

MSP430G2xx4 and G2xx5 microcontrollers are priced from $0.96/$1.12 (10,000), sampling now. The MSP430 LaunchPad expansion board
