High-Performance, Low-Power, Embedded Microprocessors

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 microprocessor comes with System Management Mode (SMM) for system and power management. SMI (System Management Interrupt) is a non-maskable, higher priority interrupt than NMI and has its own code space (1 Mbyte in Real Mode and 16 Mbyte in Protected Mode).

Applications:

■ Member of the E86™ CPU series

– 16-bit data bus

– 24-bit address bus

– 16-Mbyte address range

– Long-term stable supply from AMD

■ 40-, 33- and 25-MHz operating speeds

■ 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

■ 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

■ 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

■ 100-lead Plastic Quad Flat Pack (PQFP) package

■ Extended temperature version available
