16/32-bit Risc Flash Microcontrollers

  The TMS470R1VF4B8 device is a member of the Texas Instruments TMS470R1x family of general-purpose16/ 32-bit reduced instruction set computer (RISC) Microcontrollers The VF4B8 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 TMS470R1VF4B8 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 VF4B8 RISC core architecture offers solutions to these performance and cost demands while maintaining low power consumption. The VF4B8 device contains the following: ARM7TDMI 16/32-Bit RISC CPU TMS470R1x system module (SYS) with 470+ enhancements 256K-byte Flash 16K-byte SRAM Zero-pin phase-locked loop (ZPLL) clock module Digital watchdog (DWD) Timer Real-time interrupt (RTI) module Multi-buffered serial peripheral Interface (MibSPI) module Serial peripheral Interface (SPI) module Two serial Communications Interface (SCI) modules Two standard CAN controllers (SCC) 10-bit multi-buffered analog-to-digital converter (MibADC), with 16 input channels High-end Timer (HET) controlling 9 I/Os External Clock Prescale (ECP) Up to 47 I/O pins The functions performed by the 470+ system module (SYS) include: address decoding; Memory protection; Memory and peripherals bus supervision; reset and abort exception management; prioritization for all internal interrupt sources; device clock control; and
