Houston -- Texas Instruments is launching its MSP430F20xx microcontroller series – which offers a tiny 14-pin, 4x4mm footprint and 16 million instructions per second (MIPS) of 16-bit performance with pricing starting at 49 cents in 100K units. The MSP430F2001 is the first of more than fifty new microcontrollers in the line of low power MCUs that TI plans to introduce in the next 18 months.
"Our customers challenged us to provide a tight-fit MSP430 MCU solution for cost sensitive consumer and security systems applications without sacrificing ultra-low power, performance and ease of use," said Mark Buccini, TI’s advanced embedded controls director of marketing. "We made no compromises. At only 4x4mm, the MSP430F20xx is one of the smallest MCU available and runs at 16 bits for the price of other 8-bit MCUs. It also packs 16 MIPS and less than 1A standby with the choice of performance analog converters. These pin-compatible devices operate from 1.8V – 3.6V and unlike competitive offerings, this tiny series is fully loaded and is 100% code compatible with all existing MSP430 families, allowing developers to leverage a single MCU platform from the most basic to the most sophisticated applications," according to Buccini.
"Portable consumer and industrial applications continue to become more sophisticated, and their power requirements are outpacing by far the progress made in battery capacity,” said Max Baron, principal analyst, In-Stat. “The TI MSP430 MCU platform, designed for systems requiring ultra-low power, advances the industry's capabilities in portable power management for better battery utilization and longer standby. Aside from executing workloads at low power on its own, the MSP430 MCU can also conserve power in high-performance systems employing it as a wake-up and power sequencing device."
The new MSP430F20xx MCUs are TI’s first devices based on the recently announced F2xx architecture that operates with a cool active current of 200 A/MIPS. A flexible clock system allows operation up to 16 MHz with no external components using an improved digitally controlled oscillator (DCO) that is fully programmable and stable over temperature and voltage. The ability to switch from standby to a fully synchronized 16 MIPS active mode in less than one micro-second allows interrupt event-driven programming that extends time in power-saving modes and the use of smaller, lower cost batteries.
The 14-pin footprint combined with a sub-1A standby current provides benefits in space constrained applications such as fire and motion detectors for which OEMs may choose to reduce cost and liability with factory-installed, sealed batteries that last over ten years.
All F20xx devices offer in-system programmable flash for greater design flexibility, field upgrades and elimination of external EEPROMs. The chip's 128 bytes of RAM, when combined with a full featured CPU, allows full development in C. To further reduce system cost, all 10 GPIO pins include programmable pull-up/pull-down resistors eliminating external components. A zero-power brown-out reset (BOR) function and an enhanced watchdog timer enhance reliability. All the failsafe features of F2xx devices are available during all modes of operation with no power penalty. The MSP430F20x2 and MSP430F20x3 MCUs include a universal serial interface (USI) that can be configured for either I2C or SPI master or slave communication.

To accelerate F20xx MCU design-in, designers can begin development with TI’s existing MSP430 USB or Parallel Port JTAG pods that support the new Spy Bi-Wire interface and provide designers with world-class emulation from day one. Customer can also purchase the MSP-FET430U14, which includes a new USB-based, JTAG interface target board and a complete integrated development environment including a debugger, assembler/linker and C-complier.
The MSP430F2001 and MSP430F2011 each have 128 Kbytes of RAM and an on-chip comparator. The F2001 has 1 Kbyte of flash while the F2011 has 2 Kbytes of flash. The F2002 and 2012 each have 128 bytes of RAM and a 10-bit A/D converter rather than the comparator. The F2002 has 1 Kbyte of flash while the F2012 has 2 Kbytes of flash. The F2003 and 2013 each have 128 bytes of RAM and a 16-bit A/D converter. The F2003 has 1 Kbyte of flash while the F2013 has 2 Kbytes of flash.
The MSP430F20x3 MCUs are sampling now with full production scheduled Q4 2005. The MSP430F20x1 and MSP430F20x2 MCUs will sample Q4 2005 with production early 2006.
Following the MSP430F20xx MCU series, TI will introduce in Q4 2005 the first in a family of enhanced MSP43FG46xx processors with a 1MB memory model, allowing access to 16 times more memory compared to the 64kB available today. Extended instructions designed for the large memory model allow optimal C code density with full backward compatibility, making it possible to develop very sophisticated real-time applications completely in modular C libraries without a hand-coded assembler.
The first enhanced device from the MSP430FG46xx generation – the FG4619 MCU – will incorporate 120kB of embedded flash memory and a complete signal chain on chip (SCoC), making it ideal for applications like portable medical devices that require the high integration and large memory options of a single chip solution. In early 2006, TI’s MSP430 MCU expansion will continue with a new family of 25 MIPS devices targeted toward robust automotive and industrial applications requiring 5V and 125C capabilities.
TI will showcase the MSP430F20xx, MSP430FG46xx and other devices from the MSP430 MCU platform for the first time at the MSP430 Advanced Technical Conference (ATC), the a two day event for all MSP430 MCU developers. The ATC is held in November and December in Dallas, Texas, Munich, Germany, Taiwan as well as China. For more information on the MSP430 ATC, see www.ti.com/atc05.
