DATA SHEET  
MOS INTEGRATED CIRCUIT  
µPD4516421A, 4516821A, 4516161A for Rev. P  
16M-bit Synchronous DRAM  
Description  
The µPD4516421A, 4516821A, 4516161A are high-speed 16,777,216-bit synchronous dynamic random-access  
memories, organized as 2,097,152 × 4 × 2, 1,048,576 × 8 × 2 and 524,288 × 16 × 2 (word × bit × bank), respectively.  
The synchronous DRAMs achieve 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).  
The synchronous DRAMs are packaged in 44-pin TSOP (II) (×4, ×8) and 50-pin TSOP (II) (×16).  
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  
Dual internal banks controlled by A11 (Bank Select)  
Programmable burst-length (1, 2, 4, 8, Full Page)  
Programmable wrap sequence (Sequential/Interleave)  
Programmable CAS latency (2, 3)  
Automatic precharge and controlled precharge  
CBR (Auto) refresh and self refresh  
×4, ×8, ×16 organization  
Single + 3.3 ±0.3 V power supply  
LVTTL compatible  
Byte control (×16) by LDQM and UDQM  
2,048 refresh cycles/32 ms  
Burst termination by Burst Stop command and Precharge command
