Introduction
This section describes the main features of the TMS320VC5416, lists the pin assignments, and describes
the function of each pin. This data manual also provides a detailed description section, electrical
specifications, parameter measurement information, and mechanical data about the available packaging.
NOTE
This data manual is designed to be used in conjunction with the

Description
The TMS320VC5416 fixed-point, digital signal processor (DSP) (hereafter referred to as the device unless
otherwise specified) is based on an advanced modified Harvard architecture that has one program
memory bus and three data memory buses. This processor provides an arithmetic logic unit (ALU) with a
high degree of parallelism, application-specific hardware logic, on-chip memory, and additional on-chip
peripherals. The basis of the operational flexibility and speed of this DSP is a highly specialized instruction
set.
Separate program and data spaces allow simultaneous access to program instructions and data, providing
a high degree of parallelism. Two read operations and one write operation can be performed in a single
cycle. Instructions with parallel store and application-specific instructions can fully utilize this architecture.
In addition, data can be transferred between data and program spaces. Such parallelism supports a
powerful set of arithmetic, logic, and bit-manipulation operations that can all be performed in a single
machine cycle. The device also includes the control mechanisms to manage interrupts, repeated
operations, and function calls.
