Texas Instruments MSP430F5xx Microcontrollers

The MSP430F5xx ultra-low power MSP430 microcontrollers (MCU), from Texas Instruments Incorporated (TI) (NYSE: TXN), offers the industry’s lowest power consumption for devices that can provide up to 25 MHz peak performance, increased Flash and RAM memory and integrated peripherals such as radio frequency (RF), USB, encryption and LCD interfaces. With as low as 160 µA/MHz (microamp per megahertz) active power consumption and 1.5 µA in standby, MSP430F5xx MCUs enable longer battery life and the ability to use smaller batteries for portable applications, or no batteries at all for energy harvesting systems that run off of solar power, vibration energy or human body temperature.

The MSP430F5xx generation is 100% instruction set-compatible with earlier-generation MSP430 devices, making upgrades easy and allowing choices from the entire portfolio for applications. Supporting tools; extensive training, third party and university support; and comprehensive documentation, code examples and libraries help designers get to market quickly. Package options include both 80- and 100-pin thin quad flatpacks (TQFPs), the latter with additional general-purpose I/Os. Pricing at 1ku quantities is listed in the chart below; additionally, F5418IPN devices will be priced at $2.99 in 10ku quantities.

With more than 50% more processing performance and double the Flash and RAM memory of previous 1xx, 2xx or 4xx generations, F5xx devices help systems perform demanding tasks while operating from very limited power sources. Designers can tap into peak execution performance of up to 25 MHz while consuming as low as 160uA/MHz (microamp per megahertz). A wake up time of less than 5 microseconds with full status retention from both standby and sleep modes provides full performance on demand and instant reaction to events like external interrupts. Multi-channel direct memory access (DMA) permits data exchange with peripherals while the core remains in low-power modes. The industry’s highest code density among comparable devices maximizes performance while minimizing memory and power requirements.
