?? The TMS470R1VF448? device is a member of the Texas Instruments TMS470R1x family of general-purpose16/
32-bit reduced instruction set computer (RISC) microcontrollers. The VF448 microcontroller offers high performance utilizing the high-speed ARM7TDMI 16/32-bit RISC central processing unit (CPU), resulting in a high instruction throughput while maintaining greater code efficiency. The ARM7TDMI 16/32-bit RISC CPU views
memory as a linear collection of bytes numbered upwards from zero. The TMS470R1VF448 utilizes the bigendian
format where the most significant byte of a word is stored at the lowest numbered byte and the least
significant byte at the highest numbered byte.
?? High-end embedded control applications demand more performance from their controllers while maintaining
low costs. The VF448 RISC core architecture offers solutions to these performance and cost demands while
maintaining low power consumption.
The VF448 device contains the following:
?? ARM7TDMI 16/32-Bit RISC CPU
?? TMS470R1x system module (SYS) with 470+ enhancements
?? 256K-byte flash
