AT91SAM 32 bit ARM® RISC MCUs
AT91SAM9RL64:USB High Speed Device, Display Controller and Touch ADC |
|
|
The AT91SAM9RL is based on the ARM926EJ-S processor, with 4K byte instruction
and 4K byte data cache memories. It operates at 210MIPS with a 190 MHz clock. It
features 64K bytes of SRAM (TCM) and 32K bytes of ROM with
single cycle access at maximum processor or bus speed, together with an
external bus interface with controllers for
SDRAM and static memories including NAND Flash
and CompactFlash®. Due to the low-leakage 0.13µ silicon
process, standby power consumption is very low.
Its extensive peripheral set includes USB High Speed Device
interface (480 Mbps, UTMI+PHY)), an LCD/TFT controller
with virtual screen support, 6 channel Touch ADC
(4-wire touch) , Synchronous Serial Controllers (SSC), USARTs,
Multimedia Card Interface (MCI), Master/Slave Serial Peripheral
Interfaces (SPI), a three-channel 16-bit Timer Counter (TC), two I²C Interfaces
(TWI), AC97 Sound and 2-channel memory-to-memory DMA.
Four 32-bit Parallel I/O Controllers multiplex the pins to/from these
peripherals in order to reduce the device pin count, and peripheral DMA channels
maximize the data throughput between these interfaces and the on- and off-chip
memories.
The AT91SAM9RL has a fully featured system controller for efficient system management, including a reset controller, shutdown controller, clock management, advanced interrupt controller (AIC), debug unit (DBGU), periodic interval timer, RTC, watchdog timer and real-time timer. It is available in a 217-ball LFBGA (0.8 pitch,15x15mm) RoHS-compliant package.
Free built-in Flash programmer:
All SAM7, SAM3 and SAM9 MCUs integrate the ability to program whole Flash and associated Security/Lockbits without any additional hardware tools via USB or UART.
You can get the free appropriate Windows® program SAM-BA from www.atmel.com.
