IS46LQ32256EA-062B2LA2 – LPDDR4 SDRAM – ISSI

The ISSI IS46LQ32256EA-062B2LA2 is an 8Gb (256Mb x16 x 2-channel) automotive-grade LPDDR4 SDRAM with on-chip single-bit ECC, rated 1600 MHz (3.2 Gbps) over the -40 C to +105 C A2 temperature range in a 200-ball FBGA.

The ISSI IS46LQ32256EA-062B2LA2 is an 8Gbit CMOS Low-Power DDR4 (LPDDR4) mobile SDRAM from Integrated Silicon Solution Inc. (ISSI), built for automotive and ruggedized embedded designs that demand high bandwidth, low power, and built-in data integrity. The device is organized as 256Mb x16 across 2 channels per device, with 8 internal banks per channel, and integrates on-chip ECC providing single-bit error correction per 64 bits. The “46” product-family prefix and “A2” suffix identify this as an automotive part qualified for a -40 C to +105 C case-temperature (TC) range.
