TMS320F28335PGFA

Product Summary

The TMS320F28335PGFA is a signal controller (DSC). The C28x+FPU based controllers have the same 32-bit fixed-point architectureas TI’s existing C28x DSCs, but also include a single-precision (32-bit) IEEE 754 floating-point unit (FPU). It is a very efficient C/C++ engine, enabling users to develop their system control software in a high-level language. It also enables math algorithms to be developed using C/C++. The TMS320F28335PGFA is as efficient at DSP math tasks as it is at system control tasks that typically are handled by microcontroller devices. This efficiency removes the need for a second processor in many systems. The 32 x 32-bit MAC 64-bit processing capabilities enable the controller to handle higher numerical resolution problems efficiently. Add to this the fast interrupt response with automatic context save of critical registers, resulting in a device that is capable of servicing many asynchronous events with minimal latency. The TMS320F28335PGFA has an 8-level-deep protected pipeline with pipelined memory accesses. This pipelining enables TMS320F28335PGFA to execute at high speeds without resorting to expensive high-speed memories. Special branch-look-ahead hardware minimizes the latency for conditional discontinuities. Special store conditional operations further improve.

Features

TMS320F28335PGFA features: (1)Fully compliant with CAN protocol, version 2.0B; (2)Supports data rates up to 1 Mbps; (3)Thirty-two mailboxes, each with the following properties: Configurable as receive or transmit; Configurable with standard or extended identifier; Has a programmable receive mask; Supports data and remote frame; Composed of 0 to 8 bytes of data; Uses a 32-bit time stamp on receive and transmit message; Protects against reception of new message; Holds the dynamically programmable priority of transmit message; Employs a programmable interrupt scheme with two interrupt levels; Employs a programmable alarm on transmission or reception time-out; (4)Low-power mode; (5)Programmable wake-up on bus activity; (6)Automatic reply to a remote request message; (7)Automatic retransmission of a frame in case of loss of arbitration or error; (8)32-bit local network time counter synchronized by a specific message (communication in conjunction with mailbox 16); (9)Self-test mode: Operates in a loopback mode receiving its own message. A dummy acknowledge is provided, thereby eliminating the need for another node to provide the acknowledge bit.
