com FINAL Am386®SX/SXL/SXLV High-Performance, Low-Power, Embedded Microprocessors DISTINCTIVE CHARACTERISTICS s Member of the E86™ CPU series – 16-bit data bus – 24-bit address bus – 16-Mbyte address range – Long-term stable supply from AMD s 40-, 33- and 25-MHz operating speeds s Ideal for embedded applications – True Static design for low-power applications – 3–5 V operation (at 25 MHz) – Ideal for cost-sensitive designs – True DC (0 MHz) operation s Industry Standard Architecture – Supports world’s largest software base for x86 architectures – Wide range of chipsets and BIOS available – Fully compatible with all 386SX systems and software s System Management Mode (SMM) for system and power management (Am386SXLV only) – System Management Interrupt (SMI) for power management independent of processor operating mode and operating system – SMI coupled with I/O instruction break feature provides transparent power off and auto resume of peripherals which may not be “power aware” – SMI is non-maskable and has higher priority than Non-Maskable Interrupt (NMI) – Automatic save and restore of the microprocessor state s 100-lead Plastic Quad Flat Pack (PQFP) package s Extended temperature version available GENERAL DESCRIPTION The Am386®SX/SXL/SXLV microprocessors are lowcost, high-performance CPUs for embedded applications.
Embedded customers benefit from using the Am386 microprocessor in a number of ways.
The Am386SX/SXL/SXLV microprocessors provide embedded customers access to very inexpensive processors and the highest performance of any 386SX available anywhere.
The 16-bit data path allows for inexpensive memory design.
Full static operation, coupled with 3-V supplies, benefit customers who desire low-power designs.
Standby Mode allows the Am386SXL/SXLV microprocessors to be clocked down to 0 MHz (DC) and retain full register contents.
A float pin places all outputs in a three-state mode to facilitate board test and debug.
Additionally, the Am386SXLV m...
