IS62/65WV51216EALL IS62/65WV51216EBLL NOVEMBER 2014 512Kx16 LOW VOLTAGE, ULTRA LOW POWER CMOS STATIC RAM KEY FEATURES High-speed access time: 45ns, 55ns CMOS low power operation – 36 mW (typical) operating – 12 µW (typical) CMOS standby TTL compatible interface levels Single power supply –1.65V—2.2V VDD (62/65WV51216EALL) – 2.2V--3.6V VDD (62/65WV51216EBLL) Data control for upper and lower bytes Automotive temperature (-40oC to +125oC) DESCRIPTION The IS62WV51216EALL/ IS62WV51216EBLL are high-speed, 8M bit static RAMs organized as 512K words by 16 bits. It is fabricated using 's highperformance CMOS technology. This highly reliable process coupled with innovative circuit design techniques, yields high-performance and low power consumption devices. When is HIGH (deselected) or when CS2 is low (deselected) or when is low , CS2 is high and both and are HIGH, the device assumes a standby mode at which the power dissipation can be reduced down with CMOS input levels. Easy memory expansion is provided by using Chip Enable and Output Enable inputs. The active LOW Write Enable controls both writing and reading of the memory. A data byte allows Upper Byte and Lower Byte ( access. The IS62WV51216EALL and IS62WV51216EBLL are packaged in the JEDEC standard 48-pin mini BGA (6mm x8mm), 44-Pin TSOP (TYPE II) and 48-pin TSOP (TYPE l).

SRAM has three different modes supported. Each function is described below with Truth Table. STANDBY MODE Device enters standby mode when deselected ( HIGH or CS2 LOW or both and are HIGH). The input and output pins (I/O0-15) are placed in a high impedance state. The current consumption in this mode will be either ISB1 or ISB2 depending on the input level. CMOS input in this mode will maximize saving power. WRITE MODE Write operation issues with Chip selected ( LOW and CS2 HIGH) and Write Enable ( ) input LOW. The input and output pins(I/O0-15) are in data input mode. Output buffers are closed during this time even if is LOW. and enables a byte write feature. By enabling LOW, data from I/O pins (I/O0 through I/O7) are written into the location specified on the address pins. And with being LOW, data from I/O pins (I/O8 through I/O15) are written into the location. READ MODE Read operation issues with Chip selected ( LOW and CS2 HIGH) and Write Enable ( ) input HIGH. When is LOW, output buffer turns on to make data output. Any input to I/O pins during READ mode is not permitted. and enables a byte read feature. By enabling LOW, data from memory appears on I/O0-7. And with being LOW, data from memory appears on I/O8-15. In the READ mode, output buffers can be turned off by pulling HIGH. In this mode, internal device operates as READ but I/Os are in a high impedance state. Since device is in READ mode, active current is used.

The internal write time is defined by the overlap of =LOW, CS2=HIGH, ( or )=LOW, and =LOW. All four conditions must be in valid states to initiate a Write, but any condition can go inactive to terminate the Write. The Data Input Setup and Hold timing are referenced to the rising or falling edge of the signal that terminates the write. 4. tPWE > tHZWE + tSD when OE is LOW. 5. Address inputs must meet VIH and VIL SPEC during this period. Any glitch or unknown inputs are not permitted. Unknown input with standby mode is acceptable. 6.
