FINAL

Am386 SX/SXL/SXLV

High-Performance, Low-Power, Embedded Microprocessors

DISTINCTIVE CHARACTERISTICS

■ Member of the E86™ CPU series

– 16-bit data bus

– Fully compatible with all 386SX systems and

software

■ System Management Mode (SMM) for system

– 24-bit address bus

and power management (Am386SXLV only)

– 16-Mbyte address range

– System Management Interrupt (SMI) for power

management independent of processor

operating mode and operating system

– 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

– 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

■ Industry Standard Architecture

– Supports world’s largest software base for x86

architectures

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

■ Extended temperature version available

– Wide range of chipsets and BIOS available

GENERAL DESCRIPTION

The Am386®SX/SXL/SXLV microprocessors are low-

cost, high-performance CPUs for embedded applica-

tions. Embedded customers benefit from using the

Am386 microprocessor in a number of ways.

coupled with the I/O instruction break feature to imple-

ment transparent power management of peripherals.

SMM can be used by system designers to implement

system and power management code independent of

the operating system or the processor mode.

The Am386SX/SXL/SXLV microprocessors provide

embedded customers access to very inexpensive pro-

cessors and the highest performance of any 386SX

available anywhere. The 16-bit data path allows for in-

expensive memory design. Full static operation, cou-

pled 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 fa-

cilitate board test and debug.

Since the Am386SX/SXL/SXLV microprocessors are

supported as an embedded product in the E86 family,

customers can rely on long-term supply of product, and

extended temperature products.

In addition, customers have access to the largest se-

lection of inexpensive development tools, compilers,

and chipsets. A large number of PC operating systems

and Real Time Operating Systems (RTOS) support the

Am386SX/SXL/SXLV microprocessors. This means

cheaper development costs, and improved time to mar-

ket.

Additionally, the Am386SXLV microprocessor comes

with System Management Mode (SMM) for system and

power management. SMI (System Management Inter-

rupt) 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). SMI can be

The Am386SX/SXL/SXLV microprocessor is available

in a small footprint 100-pin Plastic Quad Flat Pack

(PQFP) package.
