The Am386®SXLV/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 Am386®SXLV/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 Am386®SXLV 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). SMI can be coupled with the I/O instruction break feature to implement 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.

Since the Am386®SXLV/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 selection of inexpensive development tools, compilers, and chipsets. A large number of PC operating systems and Real Time Operating Systems (RTOS) support the Am386®SXLV/SXL/SXLV microprocessors. This means cheaper development costs, and improved time to market.

The Am386®SXLV/SXL/SXLV microprocessor is available in a small footprint 100-pin Plastic Quad Flat Pack (PQFP) package.
