description
The SMQ320C32 is a member of the ’320C3x generation of digital signal processors from Texas Instruments.
The SMQ320C32 is an enhanced 32-bit floating-point processor manufactured in 0.7-
m triple-level-metal
CMOS technology. The enhancements to the ’320C3x architecture include a variable-width external-memory
interface, faster instruction cycle time, power-down modes, two-channel DMA coprocessor with configurable
priorities, flexible bootloader, relocatable interrupt-vector table, and edge- or level-triggered interrupts.
