• Manufacturer Part Number: m66280fp
• Description: 5120 ? 8-bit Line Memory
• Manufacturer: Renesas Electronics Corporation.

M66280FP
Variable Length Delay Bit
1 Line (5120 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.
n-bit Delay Bit
(Reset at cycles according to the delay length)
