Product Information

NanoAmp Solutions, Inc. 670 North McCarthy Blvd. Suite 220, Milpitas, CA 95035 ph: 408-935-7777, FAX: 408-935-7770 www.nanoamp.com N08T1630CxB www.DataSheet4U.com 8Mb Ultra-Low Power Asynchronous CMOS SRAM 512Kx16 bit Overview The N08T1630CxB is an integrated memory device containing a low power 8 Mbit SRAM built using a self-refresh DRAM array organized as 512,288 words by 16 bits. It is designed to be identical in operation and interface to standard 6T SRAMS. The device is designed for low standby and operating current and includes a power-down feature to automatically enter standby mode. The device operates with two chip enable (CE1 and CE2) controls and output enable (OE) to allow for easy memory expansion. Byte controls (UB and LB) allow the upper and lower bytes to be accessed independently and can also be used to deselect the device. The N08T1630CxB is optimal for various applications where low-power is critical such as battery backup and hand-held devices. The device can operate over a very wide temperature range of -40oC to +85oC and is available in JEDEC standard BGA and TSOP2 packages compatible with other standard 512Kb x 16 SRAMs. Features • Single Wide Power Supply Range 2.7 to 3.6 Volts • Very low standby current 70µA at 3.0V (Max) • Very low operating current 2.0mA at 3.0V and 1µs (Typical) • Simple memory control Dual Chip Enables (CE1 and CE2) Byte control for independent byte operation Output Enable (OE) for memory expansion • Very fast access time 55ns address access option 30ns OE access time • Automatic power down to standby mode • TTL compatible three-state output driver • Green package option for TSOP and BGA Product Family Part Number N08T1630C2BZ N08T1630C2BZ2 N08T1630C1BT N08T1630C1BT2 Package Type 48 - BGA Green 48 - BGA 44- TSOP2 Green 44- TSOP2 Operating Temperature Power Supply (Vcc) Speed Standby Operating Current (ISB), Current (Icc), Max Max @ 3.0V -40oC to +85oC 2.7V - 3.6V 55/70ns @ 2.7V 70 µA 3 mA @ 1MHz Pin Configuration (Top View) 1 A4 A3 A2 A1 A0 CE I/O0 I/O1 I/O2 I/O3 VCC VSS I/O4 I/O5 I/O6 I/O7 WE A18 A17 A16 A15 A14 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 44 43 42 41 40 39 38 37 36 35 34 33 32 31 30 29 28 27 26 25 24 23 A5 A6 A7 OE UB LB I/O15 I/O14 I/O13 I/O12 VSS VCC I/O11 I/O10 I/O9 I/O8 A8 A9 A10 A11 A12 A13 Pin Descriptions 4 A1 A4 A6 A7 A16 A15 A13 A10 2 OE UB I/O10 I/O11 I/O12 3 A0 A3 A5 A17 VSS A14 A12 A9 5 A2 CE1 I/O1 I/O3 I/O4 I/O5 WE A11 6 CE2 I/O0 I/O2 VCC VSS I/O6 I/O7 NC Pin Name A0-A18 WE CE1 CE2 OE LB UB I/O0-I/O15 VCC VSS NC Pin Function Address Inputs Write Enable Input Chip Enable 1 Input Chip Enable 2 Input (BGA only) Output Enable Input Lower Byte Enable Input Upper Byte Enable Input Data Inputs/Outputs Power Ground Not Connected A B C D E F G H LB I/O8 I/O9 VSS VCC 44 Pin TSOP2 I/O14 I/O13 I/O15 A18 NC A8 48 Ball BGA 6 x 8 mm (DOC# 14-02-004 REV H ECN# 01-1102) The specifications of this device are subject to change without notice.
