IS46QR81024A-083TBLA2 8Gb DDR4 SDRAM Memory IC 8Gbit Parallel 1.2 GHz 18 ns
The IS46QR81024A-083TBLA2 is an automotive-grade 8Gb DDR4 SDRAM from ISSI, organized as 1G×8 with a 78-TWBGA surface-mount package. Operating at a 1.2V core supply (1.14V–1.26V), it delivers a maximum data rate of 2400 MT/s with timings of CL17-17-17, targeting high-reliability automotive and industrial systems. Featuring 8 internal banks and support for DDR4 power-saving modes (including LPASR), it ensures robust performance in harsh environments with an extended temperature range of -40°C to +105°C. The device integrates advanced signal integrity features—such as write/read leveling, ZQ calibration, and data bus inversion (DBI)—to maintain signal quality, while command/address parity and data bus CRC enhance reliability for safety-critical applications.
