1.3 Description
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:
• ARM7TDMI 16-/32-bit RISC CPU
• SM470R1x system module (SYS) with 470+ enhancements
• 1MB flash
• 64KB SRAM
• ZPLL clock module
• DWD timer
• AWD timer
• Enhanced RTI module
• IEM
• MSM
• JTAG security module
• Two SPI modules
• Three SCI modules
• Two HECC
• Five I2C modules
• 10-bit MibADC, with 12 input channels
• HET controlling 12 I/Os
• ECP
(3) Throughout the remainder of this document, the SM470R1B1M will be referred to as either the full device name or as B1M.
