Description

The 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 0.13µm process technology 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 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.
