Description
The
μ
PD45256441, 45256841, 45256163 are high-speed 268,435,456 bit synchronous dynamic random-access
memories, organized as 16,777,216x4x4, 8,388,608x8x4, 4,194,304x16x4 (word x bit x bank), respectively.
The synchronous DRAMs achieved high-speed data transfer using the pipeline architecture.
All inputs and outputs are synchronized with the positive edge of the clock.
The synchronous DRAMs are compatible with Low Voltage TTL (LVTTL).
These products are packaged in 54-pin TSOP (II).
Features
Fully Synchronous Dynamic RAM, with all signals referenced to a positive clock edge
Pulsed interface
Possible to assert random column address in every cycle
Quad internal banks controlled by BA0 and BA1(Bank Select)
Byte control (x16) by LDQM and UDQM
Programmable Wrap sequence (Sequential / Interleave)
Programmable burst length (1, 2, 4, 8 and full page)
Programmable /CAS latency (2 and 3)
Automatic precharge and controlled precharge
CBR (Auto) refresh and self refresh
x4, x8, x16 organization
Single 3.3 V
±
0.3 V power supply
LVTTL compatible inputs and outputs
8,192 refresh cycles/64 ms
Burst termination by Burst stop command and Precharge command
