16位/ 32位RISC闪存微控制器 16/32-BIT RISC FLASH MICROCONTROLLER

The SM470R1B1M(3) devices are members of the Texas Instruments SM470R1x family of general-purpose 16-/32-bit reduced instruction set computer (RISC) microcontrollers. The B1M microcontroller offers high performance using 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 SM470R1B1M uses the big-endian format where the most significant byte of a word is stored at the lowest numbered byte and the least significant byte of a word is stored 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:

The functions performed by the 470+ system module (SYS) include:

The enhanced RTI module on the B1M has the option to be driven by the oscillator clock. The DWD is a 25-bit resettable decrementing counter that provides a system reset when the watchdog counter expires. This data sheet includes device-specific information such as memory and peripheral select assignment, interrupt priority, and a device memory map. For a more detailed functional description of the SYS module, see the _TMS470R1x System Module Reference Guide_ (SPNU189).

The B1M memory includes general-purpose SRAM supporting single-cycle read/write accesses in byte, half-word, and word modes.
