TDS601 is high speed multipurpose programmable I/O-Expander with built-in three USART for data-transmission. TDS601 have one set of 4bit input/output ports and seven sets of maximum 8bit input/output ports.
TDS601 has synchronous/asynchronous receiver-transmitter circuit (USART) built-in, and programmable input-output interface LSI.
It is ideal for use high speed CPU (8bit/16bit). TDS601 operate at "3.3V" or "5V" single supply voltage.

TDS701, SD host controller LSI is an interface LSI for SD memory card / SDIO card. SD host controller LSI has four serial data lines, one serial command line, a card detect signal, a write protect signal and a synchronous clock output signal. And 16 bit I/O bus is implemented to support MPU connection. Configurations and instructions will be given to this LSI via MPU connection.
When this LSI starts the data transfer with SD card, a host publishes a command through a command line first. SD card side returns a response to the command, and initializes. Then, data is transmitted and received between a host and a card through a serial data line.
TDS701 operate at "3.3V" single supply voltage.
