PC87591L-VPCN01

Product Summary

The PC87591L-VPCN01 is a highly integrated, embedded controller with an embedded-RISC core and integrated advanced functions. The PC87591L-VPCN01 is 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 PC87591L-VPCN01 replaces the on-chip flash with 4K of boot ROM for value solutions using shared BIOS architecture. PC87591x refers to all the devices. The PC87591L-VPCN01 incorporates Nationals CompactRISC CR16B core (a high-performance 16-bit RISC processor), on-chip flash (ROM for the PC87591L-VPCN01) and RAM memories, system support functions and a Bus Interface Unit (BIU) that directly interfaces with optional external memory (such as flash) and I/O devices.
