Brief Datasheet
Product Features
The Intel® StrongARM* SA-1111 Microprocessor Companion Chip (SA-1111), when coupled with the Intel® StrongARM* SA-1110 Microprocessor (SA-1110), adds a variety of functions for use in highperformance handheld computer systems. This companion chip brings a new level of integration to small systems and enables complete systems to be built with greatly reduced chip count, low power, and high performance.

Description
The SA-1111 is an integrated circuit incorporating a Universal Serial Bus (USB) controller, two PS/2 ports (mouse and trackpad), a PCMCIA and Compact Flash (CF) interface, AC-Link/I2S serial audio port, two pulse-width-modulated (PWM) outputs, and a versatile serial port. These functional blocks are connected via a fast internal synchronous bus. The System Bus Interface (SBI) connects the internal bus to the SA-1111's memory/system bus and transfers all data and control information between the SA-1111 and the SA-1110 system processor.

Universal Serial Bus (USB) Host Controller
The USB Host Controller is Open HCI-compatible, Windows95* USBD-compatible, and USBRev 1.1 compatible. It supports both low- (1.5 Mbits/s) and high-speed (12 Mbits/s) USB devices. The USB controls the transfer of data between USB peripherals (attached to the USB) and system memory. The USB uses DMA to transfer data.
PS/2 Ports
The two PS/2 ports can be used with keyboards, mice, trackpads or other PS/2-compliant devices. The PS/2 pins behave like open-drain I/Os when used in PS/2 mode. When not used for PS/2 attachment, the pins may be used as General-Purpose Input/Output (GPIO).
