 The W55P241 is a general purpose programmable I/O device usable with many different microprocessors through SPI interface. This contains three 8-bit ports, total 24 I/O pins which may be individually programmed for 4 separate command groups. These I/O pins can drive LED directly with high-current applications. A dedicated counter is in charge of 256-level output functions.
