General Presentation

SPEAr is a family of eMPU (embedded Micro Processor Unit) with customizable area running standard OS (e.g. Linux):
Based on ARM processors (ARM9 & CORTEX A9)
Standard product on SPEAr 3x0
Standard product on SPEAr 600
Standard product on SPEAr 13xx based on CORTEX A9
Including a set of standard peripherals:
DDR2 I/F, UART, SPI, I2C, IRQ, USB, Ethernet, Flash I/F, ADC, ... and specific peripherals :
JPEG codec, Crypto coprocessor, Camera interface, ...
Efficient power management features:
Dynamic clock scaling (32kHz – 333 MHz)
Clock gating (switch clock from peripherals)
Performance: from 366 to 3000+ DMIPS
High end process : 90nm (SPEA 600) - 65nm (SPEAr 3x0) - 55nm (SPEAr 13xx)
