W971GG6SB25J – DDR2 SDRAM – Winbond

The Winbond W971GG6SB25J is a 1 Gbit DDR2 SDRAM organized as 64M x 16 (8M words x 8 banks x 16 bits), DDR2-800 speed grade, in an 84-ball WBGA package with an industrial-plus -40°C to +105°C operating range. Available now for RFQ at Pacific Component Xchange.

The Winbond W971GG6SB25J is a 1 Gbit (1,073,741,824-bit) DDR2 SDRAM from the W971GG6SB specialty-DRAM family. It is organized as 8,388,608 words × 8 banks × 16 bits, equivalent to a 64M × 16 configuration, and operates from a single 1.8 V supply using the SSTL_18 interface. The 25J ordering suffix designates the DDR2-800 speed grade (5-5-5 or 6-6-6) combined with the industrial-plus temperature grade, guaranteed across a wide -40°C ≤ T_CASE ≤ +105°C range, making it well suited to harsh and embedded environments.

The device employs a double-data-rate architecture with two data transfers per clock cycle, bi-directional differential data strobes (DQS/DQS), differential clock inputs, programmable CAS latency (3, 4, 5, 6 and 7), burst lengths of 4 and 8, posted CAS additive latency, on-die termination (ODT) and off-chip-driver (OCD) impedance adjustment for improved signal integrity. It is supplied in a lead-free, RoHS-compliant 84-ball WBGA (8 × 12.5 mm) package.
