Description

The National Semiconductor PC87591L-N05 is a highly integrated embedded controller with an embedded RISC core and integrated advanced functions. This device is targeted for a wide range of portable applications that use the Low Pin Count (LPC) interface.

In this datasheet, references to the PC87591L-N05 include the PC87591L-VPCN05 and PC87591L-SLCN05.
The PC87591L-N05 incorporates the National CompactRISC CR16B core (a high-performance 16-bit RISC processor), on-chip ROM and RAM memories, system support functions and a Bus Interface Unit (BIU) that directly interfaces with external memory (such as flash) and I/O devices.

System support functions include: watchdog, PWM, timers, interrupt control, General-Purpose I/O (GPIO) with internal keyboard matrix scanning, PS/2® Interface, ACCESS.bus®interface and high-accuracy analog-to-digital (ADC) anddigital-to-analog (DAC) converters for battery charging, system control, system health monitoring and analog controls.

The PC87591L-N05 interfaces with the host via an LPC interface that provides the host with access to the following: Keyboardand embedded controller interface channels, integrated functions, Real-Time Clock (RTC) and BIOS firmware.
Like other members of the National SuperI/O family, the PC87591L-N05 is PC01 and ACPI compliant.
