The MSP430x1xx are Flash/ ROM based MCU s that offer 1.8V to 3.6V operation, up to 60kB, 8MIPs with Basic Clock. This family of MCU s offers a wide range of capabilities from a simple low power controller with a comparator, to complete systems on a chip including high-performance data converters, interfaces and multiplier.
The new ultra-low-power MSP430F2xx family increases performance up to 16 MHz. Additional enhancements of MSP430F2xx, include an integrated ±1% on-chip very lowpower oscillator, software-selectable, internal pull-up/pull-down resistors and increased number of analog inputs. The in-system programmable Flash has also been improved with smaller 64-byte segments and a lower 2.2-V programming voltage allowing the elimination of external EEPROMs in most systems. Available in low-pin count options.
The MSP430 employs a von-Neumann architecture; therefore, all memoryand peripherals are in one address space. The MSP430 devices constitute a family of ultralow-power, 16-bit RISC microcontrollers with an advanced architecture and rich peripheral set. The architecture uses advanced timing and design features, as well as a highly orthogonal structure to deliver a processor that is both powerful and flexible. The MSP430 consumes less than 400 μA in active mode operating at 1 MHz in a typical 3-V system and can wake up from a <2-μA standby mode to fully synchronized operation in less than 6 μs. These exceptionally low current requirements, combined with the fast wake-up time, enable a user to build a system with minimum current consumption and maximum battery life.
Additionally, the MSP430 family has an abundant mix of peripherals and memory sizes enabling true system-on-a-chip designs. The peripherals include a 14-bit A/D, slope A/D, multiple timers (some with capture/compare registers and PWM output capability), LCD driver, on-chip clock generation, H/W multiplier, USART, Watchdog Timer, GPIO, and others.
The ultra-low-power MSP430x4xx devices offer 1.8V-3.6V operation, up to 120kB/ Flash/ ROM 8MIPS with FLL + SVS along with an integrated LCD controller for low power metering and medical applications. Several devices offer application-based peripherals to provide single-chip solutions for flow and electricity metering.
Meet TI’s latest addition to the embedded systems microcontroller portfolio — the MSP430F5xx generation of microcontrollers. These ultra-low-power devices will provide designers with enhanced performance and increased design options with new and innovative peripherals on chips, which have more memory and integrated capabilities, while using less power than ever before. |
