This document introduces the Am186TMED/EDLV series of high-performance, 80C186- and 80C188-compatible 16-bit embedded microcontrollers from AMD. These microcontrollers have an enhanced bus interface, lower system cost, higher performance, and support 3.3V ± 0.3V operation.
This document provides technical information on the AMD Am186™ED/EDLV family of embedded microcontrollers. These devices are part of the AMD E86™ family and are based on the x86 architecture, designed as an upgrade for 80C186/188 designs requiring enhanced performance and features.
| Operating Frequencies | 20, 25, 33, and 40 MHz |
|---|---|
| Memory Address Space | 1 Mbyte |
| I/O Space | 64 Kbyte |
| PIO Pins | 32 programmable |
| Serial Ports | Two full-featured asynchronous serial ports |
| Voltage Operation (Am186EDLV) | 3.3-V + 0.3-V |
| Packages | 100-pin TQFP, 100-pin PQFP |
The primary difference is that Am186EDLV supports low-voltage operation (3.3-V + 0.3-V), whereas Am186ED does not.
No, there is no 188 version; 8-bit external bus capabilities are achieved using the 8-bit boot capability and programmable bus sizing options.
