The AK6420A/40A/80A can be a 2048/4096/8192bit, serial, read/write, non-volatile memory system fabricated utilizing anadvanced CMOS EEPROM engineering. The AK6420A has 2048bits of memory structured into 128 registers of 16bits just about every.
The AK6440A has 4096bits of memory structured into 256 registers of sixteen bits each and every.
The AK6480A has8192bits of memory organized into 512 registers of 16 bits every. The AK6420A/40A/80A can function comprehensive functionunder huge working voltage range from 1.8V to 5.5V.
The cost up circuit is built-in for top voltage generationthat is utilised for generate operation.The AK6420A/40A/80A can hook up with the serial conversation port of well-liked a person chip microcomputer specifically (3line destructive clock synchronous interface).
At create procedure, AK6420A/40A/80A requires in the publish details from datainput pin (DI) to the sign up synchronously with increasing fringe of enter pulse of serial clock pin (SK).
And at examine procedure,AK6420A/40A/80A can take out the browse information from a sign-up to knowledge output pin (DO) synchronously with falling edge ofSK.The AK6420A/40A/80A has four instructions this kind of as Examine, Produce, WREN (write allow) and WRDS (write disable).Each instruction is organized by op-code block (8bits), deal with block (8bits) and details (8bits × two).
When input amount ofSK pin is higher level and enter level of chip pick (CS) pin is changed from substantial amount to lower amount, AK6420A/40A/80Acan obtain the guidance.
