'''Am186E''' is a family of {{arch|16}} [[microcontrollers]] that incorporated the [[core name::Am186| ]]{{amd|Am186}} core along with some RAM and a number of other application-specific controllers.

== Overview ==
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 a series of [[microcontroller]]s that integrated 32K RAM on-die combined with their {{amd|Am186}} core fabricated on their new [[350 nm process]]. Later AMD introduced a number of other series which included various other peripheral controllers such as [[USB]] and communication controller.

== Members ==

=== Am186ER ===
The Am186ER series was introduced in October of [[1996]]. These MCUs incorporated the {{amd|Am186}} 32 kB of internal SRAM, non-multiplexed address bus, two independent DMA channels, programmable interrupt controller (6 interrupts), three 16-bit timers, and power saving mode.
