FT34C04A-EXX 4K 512*8 1.7V~3.6V 1MHz UDFN8 M

产品简介 :

The FT34C04A is a 1.7V rated minimum operating voltage Serial EEPROM device containing 4096-bits of Serially Electrically Erasable and Programmable Read-Only Memory (EEPROM) organized as 512-bytes of eight bits each. The Serial EEPROM operation is tailored specifically for DRAM memory modules with Serial Presence Detect (SPD) to store a module’s vital product data such as the module’s size, speed, voltage, data width, and timing parameters.The FT34C04A is protocol compatible with the legacy JEDEC EE1002 specification (2-Kbit) devices enabling the FT34C04A to be utilized in legacy applications without any software changes. The device is designed to respond to specific software commands that allow users to identify and set which half of the memory the internal address counter is located. This special page addressing method to select the upper or lower half of the Serial EEPROM is what facilitates legacy compatibility. However, there is one exception to the legacy compatibility as the FT34C04A does not support the Permanent Write Protection feature.Additionally, the FT34C04A incorporates a Reversible Software Write Protection (RSWP) feature enabling the capability to selectively write protect any or all of the four 128-byte quadrants. Once the RSWP is set, it can only be reversed by sending a specific software command sequence.The FT34C04A supports the industry standard 2-wire I2C Fast-Mode Plus (FM+) serial interface allowing device communication to operate at up to 1MHz. A bus timeout feature is supported to help prevent system lock-ups. The FT34C04A is available in space saving SOICP, TSSOP, and UDFN packages. The FT24C02A-FXRFT24C02A24C02B series areis 2048 bits of serial Electrical Erasable and Programmable Read Only Memory, commonly known as EEPROM. They are organized as 256 words of 8 bits (1 byte) each.  The devices are fabricated with proprietary advanced CMOS process for low power and low voltage applications.  These devices are available in standard 8-lead PDIP, 8-lead JEDEC SOICSOP, 8-lead MSOP, 8-lead TSSOP, 8-lead DFN and 5-lead SOT-23/TSOT-23 packages. A standard 2-wire serial interface is used to address all read and write functions.  Our extended VCC range (1.8V to 5.5V) devices enables wide spectrum of applications.
