Description
Renesas Electronics’ R1EV5801MB is an electrically erasable and programmable ROM organized as 131072-word  8-
bit. It has realized high speed, low power consumption and high reliability by employing advanced MONOS memory
technology and CMOS process and circuitry technology. It also has a 128-byte page programming function to make the
write operations faster.
