Texas Instruments Inc. (TI, Dallas, TX) introduced the TMS320R2811 and R2812 digital signal controllers for control techniques in industrial, automotive, sensing, flow metering and e-metering applications.
The new R2812 and R2811 controllers contain 20Kwords of on-chip SRAM, allowing developers to add an additional unlimited amount of external memory to their design via the serial protocol interface port. The high-performance DSP core operates at 150 MIPS for fast program execution, making the R28x generation suitable for applications such as smart sensing and measurement, which need to process multiple interrupts quickly to produce highly precise responses by processing single-cycle, 32-bit, multiply and accumulate instructions (MACs).
Available for $9.11 and $10.63, respectively, in 1,000-unit quantities, the TMS320R2811 and 2812 digital signal controllers are now available for sampling. The R2812 eZdsp is immediately available for $495.
