SPI bus 64Kbit Serial CMOS EEPROM
The AK6512C is a 65536-bit, serial, read/write, non-volatile memory device fabricated using an advanced CMOS EEPROM technology.
The AK6512C has 65536-bits of memory organized as 8192 registers of 8 bits each.
The AK6512C 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 AK6512C serial interface is compatible to a SPI bus. The AK6512C 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 CSB pin changed from
high level to low level, AK6512C can receive instructions.
