Microchip Technology, Inc. Memory AT49BV320-90UI

The AT49BV320-90UI is a 32-megabit Flash memory device from Quarktwin Technology Ltd., organized as 2,097,152 words of 16 bits each or 4,194,304 bytes of 8 bits each. It operates on a single voltage supply ranging from 3.0V to 3.6V and features an access time of 90 ns. The memory is divided into 71 sectors for erase operations, with individual write lockout capabilities for enhanced data protection. This device supports fast programming with a word program time of 15 ¬µs and a sector erase time of 200 ms. It includes a suspend/resume feature for both erase and program operations, allowing reading and programming from other sectors while one sector is being erased or programmed. The AT49BV320-90UI is designed for low power consumption, with an active current of 25 mA and a standby current of 10 ¬µA. The device is available in multiple package options, including a 48-lead TSOP, 48-ball CBGA, and ¬µBGA, making it suitable for various applications. It also includes a VPP pin for write protection and a RESET input for device initialization. The operating temperature range is specified from -40¬8C to 85¬8C, making it suitable for industrial applications.
