'''Am186Ex''' is a family of {{arch|16}} [[microcontrollers]] developed by [[AMD]] that incorporated the [[core name::Am186| ]]{{amd|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 {{amd|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 [[microcontroller]]s 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

* Serial port hardware handshaking
* independent serial port baud rate generators
* Watchdog timer can generate NMI or reset
