R8A66174SP - Renesas Technology

R8A66174SP PARALLEL-IN SERIAL-OUT DATA BUFFER

The R8A66174 is a CMOS LSI with 63-byte FIFO (First-In First-Out Memory). The commands or up to 63bytes data can be stored from 8-bit data bus. The data stored in FIFO can be outputted as serial data by executing command, and when the stored data is outputted all, R8A66174 will output an interrupt request signal. R8A66174 has 2-bit output pins (/OE, LATCH) w.
