Texas Instruments introduced their MSP430F525x microcontrollers. The new TI MCU devices reduce power consumption in “always on” applications like smart phones, tablets and accessories. Developers who transfer sensor hub, keyboard control and battery/power management functionalities to MSP430F525x MCUs can create portable consumer devices that put power-hungry application processors and touch screen controllers on standby instead of draining the system’s battery. The MSP430F525x MCUs are available now. Prices start at $2.61 for 1K units.
TI MSP430F525x Mixed Signal Microcontrollers Features
- Dual-Supply Voltage Device
- Ultralow-Power Consumption
- Wake Up From Standby Mode in 3.5 µs (typical)
- 16-Bit RISC Architecture, Extended Memory, Up to 25-MHz System Clock
- Flexible Power Management System
- Unified Clock System
- 16-Bit Timer TA0, Timer_A With Five Capture/Compare Registers
- 16-Bit Timer TA1, Timer_A With Three Capture/Compare Registers
- 16-Bit Timer TA2, Timer_A With Three Capture/Compare Registers
- 16-Bit Timer TB0, Timer_B With Seven Capture/Compare Shadow Registers
- Four Universal Serial Communication Interfaces
TI MSP430F525x MCUs feature a 1.8V split-rail I/O architecture that allows seamless interface to the application processor without needing an external level shifting circuit. Customers can now create smartphones, tablets and accessories that maintain I/O at 1.8V while operating the MCU at maximum performance. With a fast wake-up time at 3.5µs and as little as 1.6µA power consumption in standby mode, the microcontrollers can extend battery life in portable consumer products from hours to days, while simultaneously reducing board space and system cost.
All of the new MSP430F525x microcontrollers include easy-to-use software and support to help designers get started quickly. The new MCUs are compatible with MSP430Ware software so developers can access code examples to simplify development and speed time to market. In addition, the new MCUs are code compatible with existing MSP430 devices, enabling a broader range of scalability across TI’s ultra-low-power MCU portfolio.
The new 16-bit MCUs also include additional RAM, I/O and serial interfaces to handle complex sensor algorithms, aggregation and monitoring functionalities quicker.
