ASAHI KASEI
[AK6514C]
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.
