General Description

The AK6514C is a 131072-bit, serial, read/write, non-volatile memory device fabricated using an

advanced CMOS EEPROM technology.

The AK6514C has 131072-bits of memory organized as

16384 registers of 8 bits each.

The AK6514C 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 AK6514C serial interface is compatible to a SPI bus.

The AK6514C 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, AK6514C can receive instructions.
