AT49LV321-90TI is a type of memory, which is originated from Atmel Corporation. It has application field in many different areas due to its many advantages.

AT49LV321-90TI is a 32K nonvolatile electrically erasable and programmable read only memory (EEPROM) with low voltage and high reliability. It has very wide application in embedded system programming and it can be used for field upgrade and data storage.

AT49LV321-90TI has a wide voltage range with 3.0V to 5.5V, as well as single voltage operation from 4.5V to 5.5V. The memory array of AT49LV321-90TI is organized into 4096 bits with 32K bytes, with the ability to store up to 256K bits.

AT49LV321-90TI provides high speed read and program speeds to meet the real-time requirements of embedded applications. The read access time is typically 55ns with an additional 256 clock cycles and the program access time is typically 308us/8us(page mode) clock cycles.

AT49LV321-90TI also has superior reliability which makes it suitable for use in a wide range of environments. The higher endurance can reach up to 1000 cycles minimum, while the data retention is greater than 10 years.

AT49LV321-90TI consists of three separate components: a memory array, a control logic, and a write/erase circuitry. The memory array is organized such that each bit is individually erasable, allowing for selective erase, program and read operations.

The control logic is responsible for decoding and transmitting appropriate signals to the memory array and write/erase circuitry according to the opcodes and addresses received from the system. The write/erase circuitry generates a sharp pulse in the range of 4V to 6V for programming each bit of memory when the appropriate opcode is received.

AT49LV321-90TI is an ideal solution for applications needing flexibility and performance, such as embedded system programming and field upgrade. It is suitable for different product lines ranging from automotive, consumer electronics and industrial, as well as applications in smart pen drives, smart card and touch/display panel controllers.
