ASAHI KASEI
[AK6512CA]
General Description
The AK6512CA is a 65536-bit, serial, read/write, non-volatile memory device fabricated using an
advanced CMOS EEPROM technology. The AK6512CA has 65536-bits of memory organized as
8192 registers of 8 bits each. The AK6512CA 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 AK6512CA serial interface is compatible to a SPI bus. The AK6512CA 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, AK6512CA can receive instructions.
