0.8mm ARM926EJ-S 1.21.83.3V 32-bit Microprocessor SPEAr® Series SPEAR300 289-Pin 333MHz 1.2V 289-LFBGA
SPEAR300-2 Description
The SPEAR300-2 internal architecture is based on several shared subsystem logic blocks interconnected through a multilayer interconnection matrix. The switch matrix structure allows different subsystem dataflow to be executed in parallel improving the core platform efficiency. High-performance master agents are directly interconnected with the memory controller reducing the memory access latency. The overall memory bandwidth assigned to each master port can be programmed and optimized through an internally efficient weighted round-robin arbitration mechanism.
SPEAR300-2 Features
ARM926EJ-S core up to 333 MHz
High-performance 8-channel DMA
Dynamic power-saving features
Configurable peripheral functions on 102 shared I/Os
32 KB ROM and 56 KB internal SRAM
Integrated real-time clock, watchdog, and system controller
