More memory for microcontrollers
The MSP430F161x family of microcontrollers offers five times more RAM while retaining the signal-chain-on-chip character of the most popular MSP430 devices
The MSP430F161x family of microcontrollers offers five times more RAM while retaining the signal-chain-on-chip (SCoC) character of the most popular MSP430 devices. With the new MSP430F161x devices, designers will be able to tackle the toughest low-power monitoring and control design challenges while supporting higher communication throughput.

Webcast to address wireless power optimisation

Integrating up to 10Kbyte of RAM with a 200Ksample/s multichannel 12bit ADC, two 12bit DACs, two serial ports, an I2C peripheral, hardware multiplier, 10 pulsewidth modulation channels and in-system programmable Flash combined with an autonomous three-channel direct memory access controller, designers can now implement a complete closed loop system in low-power measurement and communication applications.
The expanded DMA, with triggers from all peripherals, accelerates MCU-based signal processing by providing sophisticated and configurable data transfer without CPU interaction.
DMA transfer trigger sources can be completely transparent to the CPU, allowing precise transfer control between memory and internal and external hardware.
The DMA eliminates data transfer delays and overhead, freeing the 16bit RISC CPU to spend more time processing data, instead of performing handling tasks.
'The MSP430F161x devices can sample and store larger amounts of data, enabling more extensive signal calculations, resulting in greater precision', said Cornelia Huellstrunk, MSP430 Marketing Programs Manager, TI.

'Customers are also now able to implement high level communication protocols'.
A flexible clock system with five low-power modes enables unmatched ultra-low-power performance.
The MSP430F161x family features a typical standby current consumption of just 1.9uA with a real-time-clock function active.
Engineers can tune system clocking to precisely meet the power requirements for their application.
For high-performance applications, an integrated digitally controlled oscillator or external high-speed crystal can be used to clock the system at 280uA/MIPS.
Fast instruction execution, coupled with the MSP430's CPU startup from standby of less than 6us, results in total power consumption up to 10 times lower than competing devices.
The MSP430F161x devices are fully compatible with the MSP-FET430P140 toolkit, which includes a JTAG interface target board, Flash devices, and a complete integrated development environment including a debugger, assembler/linker and limited C compiler.
The FET supports real-time, in-system development, accessing the Flash device's embedded emulation capability.
The MSP430F161x devices come in 64-pin quad flat packages (QFP).
Engineering samples are available now with full production planned in April.
