Roadmap of more than 150 new low cost MCUs delivers superior performance and leading ultra-low power to a broad range of applications, including safety, security, and touch sense.
MSP430 has dramatically increased the performance to price ratio for customers.
The MSP430 Value Line
MSP430G2xx2 Block Diagram
The MSP430 Microcontroller Value Line brings 16-bit performance, up to 16 MHz operation, integrated intelligent peripherals, and ultra-low power at low-cost 8-bit prices for cost sensitive applications.
- More than 150 devices in the family by mid-2011
- Ultra-low power
- Same 16-bit RISC architecture
- Lower price! Devices starting at US$.25 in 100k unit volumes
- Complete LaunchPad development kit for $4.30 USD. Includes free, unrestricted software compiler/debuggers
Capacitive Touch Sense IOs
The G2xx2 and upcoming G2xx3 families feature an innovative capacitive touch sense IO design. Additional circuits are added to regular GPIO modules to generate the pin oscillation, eliminating external components. Advantages to the designer using this include:
- No external components to create the oscillation
- The cap can be connected directly
- No need for external MUXes to allow multiple pads
- Each pad can directly serve as a cap sense input
- Hysteresis of ~0.7v – robust operation
Leading ultra-low power consumption drives longer battery life and smaller form factors
Typical battery powered applications spend 99-99.9% of their time in standby mode. MSP430G2xx power consumption is lower than typical 8-bit MCUs - as low as (at 2.2V):
- 0.1 µA RAM retention
- 0.4 µA Standby mode (VLO)
- 0.7 µA real-time clock mode
- Ultra-Fast Wake-Up From Standby Mode in <1 µs
Integrated intelligent peripherals – ADC10 + DTC
Competing low cost 8-bit products require the CPU to be active for each ADC conversion and loaded data transfer. MSP430's ADC10 with Data Transfer Controller (DTC) can manage ADC samples throughout entire memory range – All without CPU overhead!
- Less time in Active Mode saves power
- CPU available for other more advanced tasks
- Intelligent autonomous
- Deterministic behavior
MSP430 Value Line devices are integrated with intelligent peripherals including ADC10 with DTC, comparators, SPI, I2C, and 16-bit timers. Upcoming MSP430G2xx devices will additionally feature capacitive touch I/O pins and UART. These intelligent peripherals allow the MSP430G2xx to do more tasks independent of the CPU, lowering average current consumption and allowing the CPU to focus on more advanced tasks.
This is especially evident in sensing, security, and other low power applications. With the MSP430G2xx's integrated ADC10 with DTC, samples and memory allocation can be done autonomously without CPU intervention. Compared to competing MCUs, the intelligent peripherals integrated into the MSP430G2xx enable lower power consumption, minimize CPU activity, and improve code density.
