PC87591S - LPC Mobile Embedded Controllers

Download the PC87591S datasheet PDF. This datasheet also covers the PC8 variant, as both devices belong to the same lpc mobile embedded controllers family and are provided as variant models within a single manufacturer datasheet.

Description

The National Semiconductor PC87591E, PC87591S and PC87591L are highly integrated, embedded controllers with an embedded-RISC core and integrated advanced functions.

These devices are targeted for a wide range of portable applications that use the Low Pin Count (LPC) interface.

Features

  • Host interface, based on Intel’s LPC Interface Specification Revision 1.0, September 29th, 1997 PC01 Rev 1.0, and ACPI 2.0 compliant 16-bit RISC core, with 2 Mbyte address space, and running at up to 20 MHz Software and Hardware controlled clock throttling Shared BIOS flash memory (internal and/or external) Y2K-compliant RTC 84/117 GPIO ports (for 128-pin/176-pin packages) with a variety of wake-up events Extremely low current consumptio.

PC87591E, PC87591S and PC87591L LPC Mobile Embedded Controllers PRELIMINARY March 2004 Revision 1.07 PC87591E, PC87591S and PC87591L LPC Mobile Embedded Controllers General Description The National Semiconductor PC87591E, PC87591S and PC87591L are highly integrated, embedded controllers with an embedded-RISC core and integrated advanced functions. These devices are targeted for a wide range of portable applications that use the Low Pin Count (LPC) interface. The PC87591S is targeted for security applications and includes supporting hardware such as the Hardware Random Number Generator. The PC8591L replaces the on-chip flash with 4K of boot ROM for value solutions using shared BIOS architecture. “PC87591x” refers to all the devices.
