ARCHITECTURAL OVERVIEW
1.1
FEATURES
The Am186CC, Am186CH, and Am186CU microcontrollers, the first members of the AMD
Comm86™ family, are cost-effective, high-performance microcontroller solutions for
communications applications. These highly integrated microcontrollers enable customers
to save system costs and increase performance over 8-bit microcontrollers and other 16-bit
microcontrollers.
These microcontrollers offer the advantages of the x86 development environment’s widely
available native development tools, applications, and system software. Additionally, these
microcontrollers use the industry-standard 186 instruction set that is part of the AMD E86
family, which continually offers instruction-set-compatible upgrades. Use of this instruction
set ensures both backward and upward software compatibility.
AMD offers complete solutions with these microcontrollers. A customer development
platform board for silicon evaluation and software development is available. Reference
designs under development include a low-end router with Integrated Services Digital
Network (ISDN), Ethernet, USB, and Plain Old Telephone Service (POTS), as well as an
ISDN terminal adapter featuring USB. AMD and its FusionE86
SM
Partners offer boards,
schematics, drivers, protocol stacks, and routing software for these reference designs to
enable fast time to market.
1.2
Am186CC COMMUNICATIONS CONTROLLER
Built into the Am186CC microcontroller is a wide range of communications features required
in many communications applications, including High-level Data Link Control (HDLC) and
the Universal Serial Bus (USB). It includes the following distinctive characteristics:
■
Serial communications peripherals
– Four High-level Data Link Control (HDLC) channels
– USB peripheral controller
– Eight SmartDMA™ channels to support HDLC and USB
– Four independent Time Slot Assigners (TSAs)
– Physical interface for HDLC channels can be raw DCE, PCM Highway, or GCI (IOM-2)
– High-speed UART with autobaud
– UART
– Synchronous serial interface (SSI)
