Am186

Am186Cx is a family of 16-bit communications-oriented microcontrollers developed by AMD. These MCUs incorporated the Am186 core along with a variety of communications features 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 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)

Am186CH (HDLC)

The Am186CH series is designed for HDLC communication. These MCUs have the following additional features:

• 2x High-level Data Link Control (HDLC) channels
• 2x Time Slot Assigners (TSAs)
• 4x dedicated DMA channels (4x HDLC)

Am186CC (HDLC + USB)

The Am186CC series is designed incporates all the functionality of Am186CU and Am186CH. These MCUs have the following additional features:

• 4x High-level Data Link Control (HDLC) channels
• 4x Time Slot Assigners (TSAs)
• USB peripheral controller
• 8x dedicated DMA channels (4x HDLC + 4x USB)
