Publication Order Number: July 2008 - Rev. 8 N08L63W2A/D 8Mb Ultra-Low Power Asynchronous CMOS SRAM 512K × 16 bit Overview The N08L63W2A is an integrated memory device containing a 8 Mbit Static Random Access Memory organized as 524,288 words by 16 bits. The device is designed and fabricated using ON Semiconductor’s advanced CMOS technology to provide both high-speed performance and ultra-low power. 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 N08L63W2A 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 512Kb x 16 SRAMs Features • Single Wide Power Supply Range 2.3 to 3.6 Volts • Very low standby current 4.0µA at 3.0V (Typical) • Very low operating current 2.0mA at 3.0V and 1µs(Typical) • Very low Page Mode operating current 1.0mA 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 • Low voltage data retention Vcc = 1.8V • Very fast output enable access time 25ns OE access time • Very fast Page Mode access time tAAP = 25ns • Automatic power down to standby mode • TTL compatible three-state output driver Pin Configuration Product Family Part Number Package Type Operating Temperature Power Supply (Vcc) Speed Standby Current (ISB), Typical Operating Current (Icc), Typical N08L63W2AB 48 - BGA -40oC to +85oC 2.3V - 3.6V 70ns@2.7V 85ns @ 2.3V 4 µA2 mA @ 1MHz N08L63W2AB2 48 - BGA Green 12 34 56 A LB OE A0 A1 A2 CE2 B I/O8 UB A3 A4 CE1 I/O0 C I/O9 I/O10 A5 A6 I/O1 I/O2 D VSS I/O11 A17 A7 I/O3 VCC E VCC I/O12 NC A16 I/O4 VSS F I/O14 I/O13 A14 A15 I/O5 I/O6 G I/O15 NC A12 A13 WE I/O7 H A18 A8 A9 A10 A11 NC 48 Pin BGA (top) 8 x 10 mm Pin Descriptions Pin Name Pin Function A0-A18 Address Inputs WE Write Enable Input CE1, CE2 Chip Enable Input OE Output Enable Input LB Lower Byte Enable Input UB Upper Byte Enable Input I/O0-I/O15 Data Inputs/Outputs VCC Power VSS Ground NC Not Connected |
