Texas Instruments’ TMS470R1B1M ARM7-based MCUs with 1MB Flash memory have 60 MHz, 32-bit chips and also carry 64 kbytes of RAM. A High-End Timer (HET) co-processor provides greater accuracy in timing functions like period and pulse measurements, output compare and Pulse Width Modulations (PWMs). The HET co-processor runs independently in parallel with the ARM7 CPU, providing significantly higher throughput. Peripherals include two CAN controllers, five I2C modules, three serial communication interfaces, two serial peripheral interfaces and a 16-channel DMA controller.
Pricing for the 144-pin device starts at $14.95 for 1,000. For more information on TI’s ARM CPU, go to http://rbi.ims.ca/4927-550.
