Integrated Silicon Solution, Inc. Memory IS46LD16640A-25BLA2-TR

The IS46LD16640A-25BLA2-TR is a 1Gb (1,073,741,824 bits) mobile LPDDR2 S4 SDRAM memory device, organized as 8 banks with configurations of 64Mx16 or 32Mx32. It operates with low-voltage core and I/O power supplies, specifically VDD2 and VDDCA/VDDQ ranging from 1.14V to 1.30V, and VDD1 from 1.70V to 1.95V. The device supports a clock frequency range of 10MHz to 400MHz, achieving data rates from 20Mbps to 800Mbps per I/O through a four-bit pre-fetch DDR architecture. This memory IC features fully synchronous operations with bidirectional/differential data strobe per byte of data, programmable read/write latencies, and burst lengths of 4, 8, or 16. It includes advanced functionalities such as per-bank refresh for concurrent operation, ZQ calibration, an on-chip temperature sensor for self-refresh control, and a deep power-down mode. The operating temperature ranges from 0¬8C to 85¬8C for commercial applications and -40¬8C to 105¬8C for automotive applications. The device is packaged in a 134-ball BGA format for x16/x32 configurations.
