ADSP-BF531/ADSP-BF532/ADSP-BF533
GENERAL DESCRIPTION
The ADSP-BF531/ADSP-BF532/ADSP-BF533 processors are
members of the Blackfin
®
family of products, incorporating the
Analog Devices, Inc./Intel Micro Signal Architecture (MSA).
Blackfin processors combine a dual-MAC state-of-the-art signal
processing engine, the advantages of a clean, orthogonal RISC-
like microprocessor instruction set, and single instruction, mul-
tiple data (SIMD) multimedia capabilities into a single
instruction set architecture.
The ADSP-BF531/ADSP-BF532/ADSP-BF533 processors are
completely code and pin-compatible, differing only with respect
to their performance and on-chip memory. Specific perfor-
mance and memory configurations are shown in

PORTABLE LOW POWER ARCHITECTURE
Blackfin processors provide world-class power management
and performance. Blackfin processors are designed in a low
power and low voltage design methodology and feature
dynamic power management—the ability to vary both the volt-
age and frequency of operation to significantly lower overall
power consumption. Varying the voltage and frequency can
result in a substantial reduction in power consumption, com-
pared with just varying the frequency of operation. This
translates into longer battery life for portable appliances.
SYSTEM INTEGRATION
The ADSP-BF531/ADSP-BF532/ADSP-BF533 processors are
highly integrated system-on-a-chip solutions for the next gener-
ation of digital communication and consumer multimedia
applications. By combining industry-standard interfaces with a
high performance signal processing core, users can develop
cost-effective solutions quickly without the need for costly
external components. The system peripherals include a UART
port, an SPI port, two serial ports (SPORTs), four general-pur-
pose timers (three with PWM capability), a real-time clock, a
watchdog timer, and a parallel peripheral interface.

PROCESSOR PERIPHERALS
The ADSP-BF531/ADSP-BF532/ADSP-BF533 processors con-
tain a rich set of peripherals connected to the core via several
high bandwidth buses, providing flexibility in system configura-
tion as well as excellent overall system performance (see the
functional block diagram in
The general-
purpose peripherals include functions such as UART, timers
with PWM (pulse-width modulation) and pulse measurement
capability, general-purpose I/O pins, a real-time clock, and a
watchdog timer. This set of functions satisfies a wide variety of
typical system support needs and is augmented by the system
expansion capabilities of the part. In addition to these general-
purpose peripherals, the processors contain high speed serial
and parallel ports for interfacing to a variety of audio, video, and
modem codec functions; an interrupt controller for flexible
management of interrupts from the on-chip peripherals or
external sources; and power management control functions to
tailor the performance and power characteristics of the proces-
sor and system to many application scenarios.
All of the peripherals, except for general-purpose I/O, real-time
clock, and timers, are supported by a flexible DMA structure.
There is also a separate memory DMA channel dedicated to
data transfers between the processor’s various memory spaces,
including external SDRAM and asynchronous memory. Multi-
ple on-chip buses running at up to 133 MHz provide enough
bandwidth to keep the processor core running along with activ-
ity on all of the on-chip and external peripherals.
The processors include an on-chip voltage regulator in support
of the processor’s dynamic power management capability. The
voltage regulator provides a range of core voltage levels from
V
DDEXT
. The voltage regulator can be bypassed at the user’s
discretion.

By integrating a rich set of industry-leading system peripherals
and memory, Blackfin processors are the platform of choice for
next generation applications that require RISC-like program-
mability, multimedia support, and leading-edge signal
processing in one integrated package.
