AT29C010A-90JU

Function

• Basic Storage Function: 
• The AT29C010A - 90JU is a 5 - volt - only in - system flash programmable and erasable read - 
• only memory (PROM). It has a memory capacity of 1 Mbit, organized as 131,072 words by 8 bits.
• Fast Read Access: It offers fast read access times, up to 70 ns, enabling quick retrieval of stored data.
• Sector - Based Programming: 
• Reprogramming is performed on a sector - by - sector basis. It supports single - cycle reprogramming (erase and program). 
• Each sector is 128 bytes, and there are 1024 sectors in total. 
• It has internal address and data latches for 128 - byte operations, which means that 128 bytes of data can be loaded into the device and then simultaneously programmed.
• Data Protection: It is equipped with hardware and software data protection mechanisms to ensure the security and integrity of stored data.
• Low Power Dissipation: It has low power consumption, with an active current of 50 mA and a CMOS standby current of 100 μA.

Application

• Industrial Control Systems: 
• Due to its high - speed read - access time, reliable data storage, and wide operating temperature range (- 40 °C to + 85 °C), 
• it can be used in industrial control systems to store program codes and important data, ensuring stable operation in harsh industrial environments. 
• For example, it can store control algorithms and parameter settings in programmable logic controllers (PLCs).
• Consumer Electronics: In consumer electronic products such as set - top boxes and digital cameras, 
• it can be used to store system firmware, user - defined settings, and image data. 
• The non - volatility of flash memory ensures that data is retained even when the power is off.
• Communication Equipment: In communication devices like routers and modems, 
• it can store the device's operating system, configuration files, and routing tables. 
• The fast read and write speeds of the AT29C010A - 90JU allow for quick data processing and transmission, 
• improving the overall performance of the communication equipment.

Similar Models

• AT29C010A - 70JU: It has a similar structure and function to the AT29C010A - 90JU, 
• but the read - access time is 70 ns, which is faster than the 90 ns of the AT29C010A - 90JU. 
• It is suitable for applications that require higher - speed data access.
• AT29C010 - 90TC: This model also has a memory capacity of 1 Mbit and a parallel interface. 
• The main difference lies in the package form. The AT29C010 - 90TC uses the TSSOP32 package, 
• which has different installation characteristics and space requirements compared to the PLCC package of the AT29C010A - 90JU, 
• and is suitable for different circuit board designs.
• CAT28LV256: It is a 256 - kbit non - volatile memory with a parallel interface. 
• Although its memory capacity is smaller than that of the AT29C010A - 90JU, 
• it has a similar function and is suitable for some applications with lower memory capacity requirements. Its operating voltage range is 3V - 3.6V, 
• which is different from the 4.5V - 5.5V of the AT29C010A - 90JU, so it needs to be selected according to the specific power supply conditions of the application.
