The AS3524 is an ultra low-power microcontroller based on the ARM9 32bit
processor with fully integrated high performance audio features and system power
management in a single package for optimized system costs, combining strong
calculating power and high performance interfaces commonly used within various
application systems.
AS3524 is based on the ARM922TDMI processor, with 8K byte instruction, 8K
byte data cache memories and embedded 320K Byte SRAM with performance
from 20 ~ 266MHz.
The AS3524 SOC (system-on-a-Chip) features dedicated high speed interfaces
for ATA IDE, USB2.0 HS-OTG and SDRAM ensuring maximum performance for
download, upload, and playback.
Furthermore interfaces for NAND flashes, MMC/SD cards and Memory Stick
ensure most flexible system design possibilities. Hardware support for parallel
interfaces lower the CPU load serving complex and/or color user interfaces.
Additional serial high-speed data and control interfaces guarantee the connection
to other peripherals and or processors in the system.
Two independently programmable PLLs generate the required frequencies for
audio playback/recording, for the processor core and for the USB interface at the
same time.
AS3524 is available in a small footprint of 10x10mm, 180 CTBGA RoHS-compliant
package.
