HY57V161610ETP-I2 Banks x 512K x 16 Bit Synchronous DRAMThis document is a general product description and is subject to change without notice. Hynix Semiconductor does not assume any responsibility foruse of circuits described. No patent licenses are impliedRev. 0.1 / Nov. 2003 1DESCRIPTIONTHE Hynix HY57V161610E is a 16,777,216-bits CMOS Synchronous DRAM, ideally suited for the main memory and graphic appli-cations which require large memory density and high bandwidth. HY57V161610E is organized as 2banks of 524,288x16.HY57V161610E is offering fully synchronous operation referenced to a positive edge clock. All inputs and outputs are synchronizedwith the rising edge of the clock input. The data paths are internally pipelined to achieve very high bandwidth. All input and outputvoltage levels are compatible with LVTTL.Programmable options include the length of pipeline (Read latency of 1,2 or 3), the number of consecutive read or write cycles initi-ated by a single control command (Burst length of 1,2,4,8 or full page), and the burst count sequence(sequential or interleave). Aburst of read or write cycles in progress can be terminated by a burst terminate command or can be interrupted and replaced by anew burst read or write command on any cycle. (This pipeline design is not restricted by a `2N` rule.)FEATURES• Single 3.0V to 3.6V power supply• All device pins are compatible with LVTTL interface• JEDEC standard 400mil 50pin TSOP-II with 0.8mm of pinpitch• All inputs and outputs referenced to positive edge of systemclock• Data mask function by UDQM/LDQM• Internal two banks operation• Auto refresh and self refresh• 4096 refresh cycles / 64ms• Programmable Burst Length and Burst Type- 1, 2, 4, 8 and Full Page for Sequence Burst- 1, 2, 4 and 8 for Interleave Burst• Programmable CAS Latency ; 1, 2, 3 Clocks• Pb-free PackageORDERING INFORMATIONPart No. Clock Frequency Organization Interface PackageHY57V161610ETP-5I 200MHz2Banks x 512Kbits x 16 LVTTL400mil50pin TSOP II(Pb free)HY57V161610ETP-55I 183MHzHY57V161610ETP-6I 166MHzHY57V161610ETP-7I 143MHzHY57V161610ETP-8I 125MHzHY57V161610ETP-10I 100MHzHY57V161610ETP-15I 66MHzNote :1.
