Microchip Technology, Inc. Memory AT29BV020-12JC

The AT29BV020-12JC is a 2-megabit Flash Programmable and Erasable Read Only Memory (PEROM) from Quarktwin Technology Ltd. It operates with a single supply voltage ranging from 2.7V to 3.6V, making it suitable for low-power applications. The device features a fast read access time of 120 ns and a low active current of 15 mA, with a standby current of less than 40 ¬µA. This memory chip is organized as 262,144 words by 8 bits and includes 1024 sectors of 256 bytes each. It supports sector programming with a maximum cycle time of 20 ms and has a typical endurance of over 10,000 write cycles. The AT29BV020-12JC is compatible with both CMOS and TTL logic levels, and it includes built-in data polling for end-of-program detection. The device is available in a 32-lead PLCC package and is suitable for commercial temperature ranges from 0¬8C to 70¬8C. It is designed for in-system reprogrammability without the need for high input voltages, making it a flexible option for various applications.
