16/32-bit Risc Flash Microcontroller

  The TMS470R1B1M (1) devices are members of the Texas Instruments TMS470R1x family of general-purpose 16/32-bit reduced instruction set computer (RISC) Microcontrollers The B1M 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 TMS470R1B1M utilizes the big-endian 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 B1M RISC core architecture offers solutions to these performance and cost demands while maintaining low power consumption. The B1M devices contain the following: ? ARM7TDMI 16/32-Bit RISC CPU ? TMS470R1x system module (SYS) with 470+ enhancements ? 1M-byte Flash ? 64K-byte SRAM ? Zero-pin phase-locked loop (ZPLL) clock module ? Digital watchdog (DWD) Timer ? Analog watchdog (AWD) Timer ? Enhanced real-time interrupt ( RTI) module ? Interrupt expansion module (IEM) ? Memory security module (MSM) ? JTAG security module ? Two serial peripheral Interface (SPI) modules ? Three serial Communications Interface (SCI) modules ? Two high-end CAN controllers (HECC) ? Five inter-integrated circuit (I2C) modules ? 10-bit multi-buffered analog-to-digital converter (MibADC), with 12 input channels ? High-end Timer lite (HET) controlling 12 I/Os ? External clock prescale (ECP) ? Expansion bus module (EBM) ? Up to 93 I/O pins The functions performed by the 470+
