General Description

The AK6510C/12C is a 32768/65536-bit, serial, read/write, non-volatile memory device fabricated

using an advanced CMOS EEPROM technology.

The AK6510C/12C has 32768-bits/65536-bits of

memory organized as 4096/8192 registers of 8 bits each.

The AK6510C/12C can operate all

function under wide operating voltage range: 1.8V to 5.5V.

The charge up circuit for high voltage

generation needed for write operations is integrated.

The AK6510C/12C serial interface is compatible to a SPI bus.

The AK6510C/12C has 6

instructions: READ, WRITE, WREN (write enable), WRDI (write disable), RDSR (read status

register), and WRSR (write status register).

Each instruction is organized by an op-code (8bits), address (16bits), and data (8bits).

When input

level of CS pin changed from high level to low level, AK6510C/12C can receive instructions.
