Central Processor (sheet 1)
The system central processor is a highly integrated microprocessor that incorporates a 32-bit StrongARM
RISC processor core, system support logic, multiple communication channels, an LCD controller, a
PCMCIA controller, and general-purpose I/O ports.
Processor Summary (U8, sheet 1)
The SA-1100 Microprocessor is a general-purpose, 32 bit RISC microprocessor with the following features:
 16 Kbyte instruction cache
 8 Kbyte write-back data cache
 512 byte mini data cash that allocates data based on the MMU
 4 entry read buffer and an 8 entry write buffer
 Integral memory management unit ( MMU )
The logic outside the core and caches is grouped into the following three modules:
 Memory and PCMCIA control module ( MPCM )
 Memory interface supporting ROM, Flash, DRAM, SRAM, and PCMCIA control signals
 System control module ( SCM )
 Twenty-eight general purpose I/O ports (interrupt capable)
 Real-time clock, watchdog, and interval times
 Power management controller
 Interrupt controller
 Reset controller
 Two on-chip oscillators for connection to 3.686 MHz and 32.768 kHz crystals
 Peripheral control module ( PM )
 Six-channel DMA controller
 Gray/color, active/passive LCD controller
 230 Kbps SDLC controller
 16550 compatible UART
 IrDA serial port (115 Kbps, 4 Mbps )
 Synchronous serial port (UCB1100, UCB1200, SPI, TI, uWire )
