Am186 |
Am186E is a family of 16-bit microcontrollers that incorporated the 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 microcontrollers that integrated 32K RAM on-die combined with their 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 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.
