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 N02M083WL1A www.DataSheet4U.com 2Mb Ultra-Low Power Asynchronous Medical CMOS SRAM 256Kx8 bit Overview The N02M083WL1A is an integrated memory device intended for non life-support (Class 1 or 2) medical applications. This device comprises a 2 Mbit Static Random Access Memory organized as 262,144 words by 8 bits. The device is designed and fabricated using NanoAmp’s advanced CMOS technology with reliability inhancements for medical users. The base design is the same as NanoAmp’s N02M0818L2A, which has further reliability processing for life-support (Class 3) medical applications. The device operates with two chip enable (CE1 and CE2) controls and output enable (OE) to allow for easy memory expansion. The N02M083WL1A 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 packages compatible with other standard 256Kb x 8 SRAMs Features • Single Wide Power Supply Range 2.3 to 3.6 Volts • Low standby current 3µA maximum at 3.6V • Very low operating current 2 mA at 3.6V and 1Mhz (Typical) • Very low Page Mode operating current 0.5mA at 3.6V and 1Mhz (Typical) • Simple memory control Dual Chip Enables (CE1 and CE2) Output Enable (OE) for memory expansion • Low voltage data retention Vcc = 1.8V • Automatic power down to standby mode • TTL compatible three-state output driver Product Family Standby Current (ISB), Max 3.0 µA Operating Current (Icc), Max 2.5 mA @ 1MHz Part Number N02M083WL1AN Package Type 32 - STSOP I Operating Temperature -40oC to +85oC Power Supply (Vcc) 2.3V - 3.6V Speed N02M083WL1AD Known Good Die 70ns @ 2.3V Pin Configuration A11 A9 A8 A13 WE CE2 A15 VCC A17 A16 A14 A12 A7 A6 A5 A4 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 32 31 30 29 28 27 26 25 24 23 22 21 20 19 18 17 OE A10 CE1 I/O7 I/O6 I/O5 I/O4 I/O3 VSS I/O2 I/O1 I/O0 A0 A1 A2 A3 Pin Descriptions Pin Name A0-A17 WE CE1, CE2 OE I/O0-I/O7 VCC VSS Pin Function Address Inputs Write Enable Input Chip Enable Input Output Enable Input Data Inputs/Outputs Power Ground N02M083WL1A STSOP Stock No. 23207-01 11/01/02 The specifications of this device are subject to change without notice.
