TI Announces Five New Microcontroller Families

December 11, 2007

The MSP430F2xx high-performance 16-bit MCUs deliver twice the battery life of previous models.


DALLAS /PRNewswire/ -- Texas Instruments Inc. (TI) announced the availability of five new families of MSP430F2xx high-performance microcontrollers, the "industry's lowest-power 16-bit general-purpose microcontrollers (MCUs)." The new microcontrollers provide a direct upgrade path for corresponding devices in TI's popular MSP430F1xx generation of ultra-low-power MCUs, easing development and offering complete software and pin compatibility while delivering "twice the performance, twice the battery life, and increased memory." MSP430F2xx MCUs enable developers of meters, sensors, industrial control systems, handheld instruments, and a host of other embedded systems to extend the performance and lifetime of their products with minimal redesign.

With a high level of analog integration, TI's MSP430F2xx MCU architecture is designed for the requirements of a new generation of control systems. The devices integrate on-chip memories of up to 120 KB, and a 20-bit address word increases total addressable memory to 1 MB without paging, supporting the development of more complex programs. A wide range of analog and digital peripheral options enable enhanced features in end products while reducing system costs and power consumption.

For example, almost no battery drain occurs with standby power consumption as low as 0.5 µA, and fast wake up from standby mode further reduces battery load. The MCUs have a wide operating voltage range of 1.8–3.6 V and a flexible clocking architecture that allows the designer to implement select processing speeds versus operating voltage. Battery life and system cost are further optimized by achieving the full processor speed of 16 MHz, at 3.3 V, giving margin for the power-supply design requirements.

The five new MCU families fulfill TI's commitment to provide a complete line of F2xx upgrades to its MSP430 customers. On-chip options available among the devices include program memories up to 120 KB, three-channel direct memory access, eight-channel 12-bit ADCs, and two-channel 12-bit DACs. A universal serial communications interface saves development time with a flexible implementation of standards that include I2C, SPI, IrDA, and UART.

With up to 120 KB of flash and 8 KB of RAM, the MSP430F241x and MSP430F261x are targeted for systems needing extensive processing capability, while the MSP430F24x and MSP430F23x are more general-purpose devices. Among the devices, the MSP430F2418 and MSP430F2618 are optimized for operation in low-power ZigBee networks, while the MSP430F2410 targets applications such as IEEE 802.15.4 wireless networks and automatic meter reading.

"The release of the new MSP430F2xx MCU products offers more than upgrades to higher performance, lower power, and more design flexibility to our MSP430 customers," said Kevin Belnap, MSP430 Product Marketing Manager. "It also opens a new range of application possibilities for portable embedded control systems that require more memory, as well as other systems that can benefit from the high level of analog integration."
