AT91RM3400
AT91RM3400 产品描述
The AT91RM3400 features a 60 MIPS ARM7TDMI processor with 96K bytes of SRAM, 256K bytes of ROM, USB Device Interface, Power Management Controller, Real Time Clock, System Timer, Synchronous Serial Controller, 6-channel Timer Counter, 4-channel USART, Two-wire Interface, Serial Peripheral Interface and Parallel I/O Controller. It does not feature an External Bus Interface.
The AT91RM3400 is a fully integrated member of the Atmel advanced AT91 ARM
microcontroller family. Having no external memory interface and equipped with embedded
SRAM and ROM, it is ideal for numerous applications with medium memory
requirements but which demand high performance.
Several options are available to download software to the internal SRAM. These include
downloading from a serial EEPROM or serial DataFlash?or downloading through the
USB Device Port. Additionally, customizing of the embedded ROM is available on
request for large volume opportunities.
The Advanced Interrupt Controller (AIC) enhances the interrupt handling performance of
the ARM7TDMI processor by providing multiple vectored, prioritized interrupt sources
and reduces the cycles taken to transfer to an interrupt handler.
The Peripheral Data Controller (PDC) provides DMA channels for all the serial peripherals,
enabling them to transfer data to or from on-chip memories without processor
intervention. This reduces the processor overhead when dealing with transfers of continuous
data streams.
The set of Parallel I/O (PIO) Controllers multiplex the peripheral input/output lines with
general-purpose data I/Os, reducing the external pin count of the device and providing
an interrupt and open drain capability on each line.
The Power Management Controller (PMC) keeps system power consumption to a minimum
by selectively enabling and/or disabling the core and various peripherals under
software control. It uses an enhanced clock generator to provide a selection of clock signals
including a slow clock (32 kHz) for power-saving mode.
The wide range of system interfaces includes USB V2.0 Full-speed Device Port, Multimedia
Card, Serial Peripheral Interface (SPI) and Two-wire Interface (TWI). Peripherals
include multiple USARTs, Timer/Counters and Serial Synchronous Controllers (SSC).
The AT91RM3400 includes an extensive set of peripherals that operate in accordance
with several industry standards, such as those used in audio, communication, computer
and smart card applications.
