• Manufacturer Part Number: M66258
• Description: 8192 x 8-BIT LINE MEMORY
• Manufacturer: Mitsubishi

VARIABLE LENGTH DELAY BIT
(Reset at cycles according to the delay length)
1 line (8192 bits) delay
Input data can be written at the rising edge of WCK after write cycle and output data is read at the rising edge of RCK before read cycle to
easily make 1 line delay.
