Integrated Silicon Solution, Inc. Memory IS43LQ32128A-062BLI-TR

The IS43LQ32128A-062BLI-TR is a 4Gb mobile LPDDR4 SDRAM memory device from Quarktwin Technology Ltd. It features a configuration of 256Mb x16 with 1 channel and 128Mb x16 with 2 channels, incorporating 8 internal banks per channel. The device operates with low-voltage power supplies, with VDD1 ranging from 1.70V to 1.95V, and VDD2 and VDDQ between 1.06V to 1.17V for LPDDR4, and 0.57V to 0.65V for LPDDR4X. This memory supports a maximum clock frequency of 1.6GHz, achieving data rates of 3.2Gbps. It utilizes a 16n prefetch DDR architecture, allowing for high-speed synchronous operations referenced to both rising and falling clock edges. The device is packaged in a 200-ball x16/x32 BGA format measuring 10x14.5mm, and it is suitable for industrial and automotive applications with operating temperatures ranging from -40°C to 125°C. Key features include dynamic ODT, internal VREF and VREF training, programmable burst lengths, and ZQ calibration. The memory also supports clock-stop capability and includes an on-chip temperature sensor. This product is designed for applications requiring high bandwidth and low power consumption.
