ADSP-BF539F

製品概要

The Blackfin® Processor family has been expanded to address the ever-increasing need for more connection possibilities. This connectivity is coupled with the high performance 16-/32-bit Blackfin embedded processor core, the flexible cache architecture, the enhanced DMA subsystem, and the Dynamic Power Management (DPM) functionality. System designers can take advantage of the combined control and signal processing capabilities of the processor core through code compatibility of these new family members with existing Blackfin offerings.

The ADSP-BF539F Processors are designed and targeted for use as the System Control Processor in control and signal processing rich applications such as Automotive Navigation Systems, Audio Head Units and Audio Amplifiers. The ADSP-BF539F is equivalent in functionality to the ADSP-BF539 processor with the exception of the addition of onboard FLASH memory.

Blackfin Processors add FLASH memory and MOST Network Connectivity
A new addition to the Blackfin Processor family is the inclusion of integrated FLASH memory alongside the processor. There are two choices available in the ADSP-BF539F family, one with 4 Mbit of onboard FLASH memory and one with 8 Mbit of onboard FLASH memory. Both offer large code space for complex embedded systems and fast (70 ns) access time to the Blackfin core.

FLASH Memory Data Sheets:
4 Megabit (512 K x 8-Bit/256 K x 16-Bit) FLASH memory
8 Megabit (1 M x 8-Bit/512 K x 16-Bit) FLASH memory

This is in addition to the complementary Blackfin processor memory system that offers a powerful and flexible cache architecture that can dynamically balance between the hard real-time tasks desired in SRAM and soft real-time control tasks and an Operating System (OS) requiring cache functionality.

These powerful new processors also integrate an MXVR Transceiver for transmitting and receiving audio, video and control data over a MOST automotive multimedia network. Dynamic Power Management additionally lowers power consumption and minimizes power dissipation in enclosed applications.

Designed as an Integrated System
In addition to the embedded connectivity of CAN 2.0B, the ADSP-BF539F processors include a variety of general purpose functions designed to minimize external IC count and offer broad control and communication. Peripherals include three SPI®-compatible ports, three UARTs, four SPORT ports, three multifunction timers, 38 general-purpose I/Os, dual Two-Wire Interface for I2C operation, a real-time clock, a watchdog timer, an event controller, and a JTAG/debug interface. The flexible Parallel Peripheral Interface (PPI) offers a direct connection to a variety of video encoders/ decoders, display drivers, image sensors, and general-purpose converters.
