Am186Ex is a family of 16-bit microcontrollers that incorporated the Am186 core along with a number of other application-specific features designed for various embedded applications.

Overview
The Am186Ex is a family of microcontrollers that incorporated the Am186 core along with a number of units. AMD introduced a number of series including: Am186EM, Am186ES, Am186ER, Am186ED.
All MCUs include the following base features:
- Single clock input
- Interrupt Control Unit
- General Purpose DMA (2 independent channels)
- 3 x 16-bit timers
- Watchdog Timer
- UART
- 32x General Purpose IO
- Synchronous Serial Interface
Members
Am186EM
The Am186EM series was introduced in 1995 and included the base features only. Note that this MCU does not have a dedicated watchdog timer, instead timer 1 (from the 3 available timers) can be used a watchdog timer.
- 6 x external interrupts
Am186ES
The Am186ES included all the base features as well as the following:
- 8-bit or 16-bit memory and I/O static bus modes
- Serial port hardware handshaking
- independent serial port baud rate generators
- Watchdog timer can generate NMI or reset
- Pseudo static RAM (PSRAM) controller
- pulse-width demodulation
- 8 x external interrupts
- 8 x internal interrupts
Am186ER
With low-density SRAM (less than 4 Megabit) on the decline in the mid 1990s, the typical off-the-shelf setup would require 64K SRAM in a 2 x 32K setup to satisfy the 186's 16-bit external data bus. For the average system that would mean twice the general SRAM needed. AMD's introduced the Am186ER series in 1996. These microcontrollers supported all the features of the Am186ES as well as 32K of integrated RAM on-die.
- Watchdog timer can generate NMI or reset
- 6 x external interrupts
- 32 KB SRAM
Am186ED
The Am186ED supported all the features of the Am186ES but also incorporated a programmable DRAM controller.
- programmable DRAM controller
- 8-bit or 16-bit memory and I/O static bus modes
- Serial port hardware handshaking
- independent serial port baud rate generators
- Watchdog timer can generate NMI or reset
- pulse-width demodulation
- 8 x external interrupts
- 8 x internal interrupts
