[AK6510C/12C]
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.
