Peripheral
Analog to Digital Converter
Our 8-bit A/D converters are using synchronous 3-wire serial interface with guaranteed 8-bit resolution. Each channel can be independently programmed to an analog input mode and supports A/D conversion rates up to 50KHz. Used in applications that require fewer external components.

I/O Expander
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. W55P241 SPI Interface, 3-bit Ports I/O Expander
