HSD16M32F4VP
Synchronous DRAM Module, 64Mbyte ( 16M x 32-Bit ) SMM based on
2Mx16Bitx4Banks, 4K Ref., 3.3V
Part No. HSD16M32F4VP
GENERAL DESCRIPTION
The HSD16M32F4VP is a 16M x 32 bit Synchronous Dynamic RAM high density memory module. The module consists
of four CMOS 2M x 16 bit with 4banks Synchronous DRAMs in TSOP-II packages is mounted on a 80-pin, single-sided,
FR-4-printed circuit board., Two 0.1uF decoupling capacitors are mounted on the printed circuit board in parallel for each
SDRAM. The HSD16M32F4VP is a SMM (Stackable Memory Module) designed and is intended for mounting into two 40-
pin connector sockets. Synchronous design allows precise cycle control with the use of system clock. I/O transactions are
possible on every clock cycle. Range of operating frequencies, programmable latencies allows the same device to be
useful for a variety of high bandwidth, high performance memory system applications All module components may be
powered from a single 3.3V DC power supply and all inputs and outputs are LVTTL-compatible.
