AK6481CH中文资料旭化成微电子数据手册PDF规格书

General Description

The AK6480C/81C is a 8192bit, serial, read/write, non-volatile memory device fabricated using an advanced CMOS EEPROM technology. The AK6480C/81C has 8192bits of memory organized into 512 registers of 16 bits each. The AK6480C/81C can operate full function under wide operating voltage range from 1.8V to 5.5V. The charge up circuit is integrated for high voltage generation that is used for write operation.
