1. Value based on test complying with RAI-5-048-RA human body model ESD testing.DescriptionThe PC87570 is a highly integrated embedded RISC-based controller optimized for power management (PM), keyboard and mouse (KBC) and system control in portable Personal Computer (PC) applications.
The PC87570 incorporates National's CompactRISCä CR16A core, a high performance 16-bit RISC processor core, a Bus Interface Unit (BIU) that directly interfaces with memory and I/O devices, on-chip memory and system support functions. Among these are legacy functions, handled by the Host Bus Interface (HBI), that include the Real-Time Clock and Advanced Power Control (RTC and APC), and peripherals, including: frequency-multiplier-based High Frequency Clock Generator (HFCG), Power Mode Control (PMC), Interrupt Control Unit (ICU), Multi-Input Wake-Up (MIWU), General Purpose I/O Ports (GPIO) with internal keyboard matrix scanning, PS/2® Interface, ACCESS.bus® (ACB) Interface, two Multi-Function 16-Bit Timers (MFT16), periodic interrupt timer and WATCHDOGä (TWD), ADC
and DAC.
The PC87570 highly efficient architecture and its on-chip peripherals, supporting functions and low power consumption, provide a highly integrated solution for portable notebook PCs, sub-notebook PCs and other portable devices.
