TI Announces New MCUs With Embedded Full-Speed USB & Low Power Consumption

July 20, 2009 by Jeff Shepard

Texas Instruments Inc. (TI) announced the new MSP430F55xx microcontroller (MCU) family with embedded full-speed USB (12 Mbps). TI claims the new F55xx family offers the world’s leading ultra-low power consumption combined with high-performance analog and other smart integrated peripherals. Helping cut the power cord, the F55xx MCUs are well-suited for cost-sensitive applications including portable measurement for medical, industrial, and health and fitness, as well as consumer electronics and a broad range of other applications.

Key features and benefits of the MSP430F55xx include: five low-power modes are said to include the industry’s lowest power consumption in active mode at 200µA/MHz and standby mode at 2.5µA with wake-up from standby mode in less than 5µs for extended battery life; expanded memory range covering 8KB to 128KB flash offers easy migration path; high performance analog including 10-bit or 12-bit ADC options that consume less than 200µA during operation, and an ultra-low power sub-microamp comparator designed for wide application usage.

Further feature and benefits include: integrated intelligent peripherals including hardware multiplier, four 16-bit timers, and up to four interfaces of serial communication including UART, SPI, and I²C; various package options with small footprint, including 48-pin (QFP, QFN), 64-pin (QFN), 80-pin (QFP, BGA); fully integrated LDO powered directly from the 5V bus power saves cost and board space; and a broad USB portfolio with more than 35 device options offers enhanced peripheral and analog integration, increased memory and package options.

F55xx MCUs are priced from sub-$1 in large volumes. All are instruction set compatible with the entire MSP430 platform. The MSP430F552x sample kit is available now and includes two 80-pin QFN sample devices, TS430PN80USB target board and supporting documents and software to get started. The MSP430F552x MCUs are sampling today with production volumes as early as November 2009. This device is fully compatible with the $149 MSP-FET430U80USB and $99 MSP-FET430UIF flash emulation tools.
