描述 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.
