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 ≤ TCASE ≤ +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.
The W971GG6SB25J is an obsolete / hard-to-find DDR2 memory device with little to no authorized-distributor availability. Pacific Component Xchange is an independent distributor specializing in legacy and end-of-life memory, and we currently hold inventory of this part. Every order is backed by our authenticity and quality-assurance process to protect your build from counterfeit or substandard components, with global shipping to support production lines worldwide.
Because this is a scarce, allocation-sensitive device, pricing is provided on request. Request a quote (RFQ) today and our sourcing team will confirm available quantity, date codes and lead time for the W971GG6SB25J.
It is a 1 Gbit DDR2 SDRAM organized as 64M x 16 (8,388,608 words x 8 banks x 16 bits) from Winbond's W971GG6SB family, supplied in an 84-ball WBGA package and operating at 1.8 V.
In Winbond's ordering scheme the 25 designates the DDR2-800 speed grade (5-5-5 or 6-6-6). The J denotes the industrial-plus temperature grade guaranteed over -40 C to +105 C T_CASE.
The W971GG6SB25J ships in a lead-free, RoHS-compliant 84-ball WBGA (8 x 12.5 mm) package and runs from a single 1.8 V +/- 0.1 V supply using the SSTL_18 interface.
The device supports CAS latencies of 3, 4, 5, 6 and 7 and burst lengths of 4 and 8, along with posted CAS additive latency, ODT and OCD impedance adjustment.
No. This DDR2 SDRAM is obsolete with little to no authorized-distributor availability. Pacific Component Xchange stocks it as a hard-to-find part and can provide a quote on request.
