The BQ4011MA-100 is a non-volatile static RAM (NVSRAM) memory device from Quarktwin Technology Ltd., featuring a capacity of 256Kbits organized as 32,768 words by 8 bits. It operates at supply voltages of either 5V or 3.3V and is housed in a standard 28-pin DIP package. This memory device is designed for applications requiring data retention for at least 10 years without power, utilizing an integral lithium energy source for non-volatility. The BQ4011MA-100 supports unlimited write cycles typical of conventional SRAM, while also incorporating automatic write protection during power-up and power-down cycles to prevent data corruption. The device features low standby current consumption and does not require external circuitry, making it compatible with existing 256Kb SRAM pinouts. It is suitable for use in various applications where reliable data retention and fast access times are critical.
