StrongARM SA-1100 Processor
Integrated RISC core + I/O controllers
- SA-110 core, reduced D-cache to 8KB
- add controllers for memory, LCD, power management, UART, IrDA, PCMCIA, USB, GPIO pins, RT clock, etc.
High Performance, Low Power
- 200MHz: 230 Dhrystone MIPS @ 200mW
- “desktop performance on AAA batteries”
Power Management Options
- idle mode: stops clock, maintains state, fast wakeup
- sleep mode: power down chip except real-time clock
- vary clock rate: 30 – 200MHz
