Am186Cx is a family of 16-bit communications-oriented microcontrollers developed by AMD. These MCUs incorporated the Am186 core along with a variety of serial communication peripherals such as High-Level Data Link Control (HDLC), Universal Serial Bus (USB), High-Speed UART, and Synchronous Serial Interface (SSI).

Overview

The Am186Cx is a family of serial communication-oriented microcontrollers that incorporated the Am186 core along with a number of other units. AMD introduced a number of series including: Am186CU, Am186CH, Am186CC.

All MCUs include the following base features:

• High-Speed UART with autobaud
• Synchronous serial interface (SSI)
• 3x programmable 16-bit timers
• Hardware watchdog timer
• 4x General-purpose DMA channels
• 48x Programmable I/O ports
• 36x maskable interrupts
• Interrupt Controller
• Integrated DRAM controller
• 14x chip selects (8x peripherals, 6x memory)
• Multiplexed and nonmultiplexed address/data bus

Members

Am186CU (USB)

The Am186CU series is designed for USB communication. These MCUs have the following additional features:

• USB peripheral controller
• 4x dedicated DMA channels (4x USB)
