DescriptionThe AS3524 is an ultra low-power microcontroller based on the ARM9 32bit processor combining strong calculating power and high performance interfaces commonly used within various application systems.
Using advanced 0.13m process technology of AS3524 and a large on chip RAM leads to outstanding low power consumption of 0.3 mW/MHz for the ARM922T microcontroller core and 0.6 mW/MHz for the overall system measured with a typical audio SW application.
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 of AS3524 support for parallel interfaces lower the CPU load serving complex and/or color user interfaces.
Additional serial high-speed data of AS3524 and control interfaces guarantee the connection to other peripherals and or processors in the system.
Two independently programmable PLLs AS3524 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.
