M68AR512D
SUMMARY DESCRIPTION The M68AR512D is an 8 Mbit (8,388,608 bit) CMOS SRAM, organized as 524,288 words by 16 bits. The device features fully static operation requiring no external clocks or timing strobes, with equal address access and cycle times. It requires a single 1.8V (150mV) supply. This device has a Chip Select pin (E2) for easy memory expansion; when it is active (E2 high) the device has an auto-
matic power-down feature, reducing the power consumption by over 99%. The M68AR512D is available in TFBGA48 (6x7mm and 8x10mm, 6x8 active ball array, 0.75 mm ball pitch) package. See the Ordering Information Scheme (Table 12) for details.

OPERATION The M68AR512D has a Chip Enable power down feature which invokes an automatic standby mode whenever Chip Enable is de-asserted (E1 = High) or Chip Select is asserted (E2 = Low), or UB/LB are de-asserted (UB/LB = High). An Output Enable (G) signal provides a high speed tri-state conTable 6. Operating Modes

Read Mode The M68AR512D, when Chip Select (E2) is High, is in the read mode whenever Write Enable (W) is High with Output Enable (G) Low, and Chip Enable (E1) is asserted. This provides access to data from eight or sixteen, depending on the status of the signal UB and LB, of the 8,388,608 locations in the static memory array, specified by the 19 address inputs. Valid data will be available at the
eight or sixteen output pins within tAVQV after the last stable address, providing G is Low and E1 is Low. If Chip Enable or Output Enable access times are not met, data access will be measured from the limiting parameter (tELQV, tGLQV or tBLQV) rather than the address. Data out may be indeterminate at tELQX, tGLQX and tBLQX, but data lines will always be valid at tAVQV.

At any given temperature and voltage condition, tGHQZ is less than tGLQX, tBHQZ is less than tBLQX and tEHQZ is less than tELQX for any given device. 3. These parameters are defined as the time at which the outputs achieve the open circuit conditions and are not referenced to output voltage levels. 4.

M68AR512D
Write Mode The M68AR512D, when Chip Select (E2) is High, is in the Write Mode whenever the W and E1 are Low. Either the Chip Enable Input (E1) or the Write Enable input (W) must be de-asserted during Address transitions for subsequent write cycles. When E1 or W is Low, and UB or LB is Low, write cycle begins on the W or E1 falling edge. When E1 and W are Low, and UB = LB = High, write cycle begins on the first falling edge of UB or LB. Therefore, address setup time is referenced to Write Enable, Chip Enables and UB/LB as tAVWL, tAVEL and tAVBL respectively, and is determined by the latter occurring falling edge.
The Write cycle can be terminated by the earlier rising edge of E1, W, UB and LB. If the Output is enabled (E1 = Low, E2 = High, G = Low, LB or UB = Low), then W will return the outputs to high impedance within tWLQZ of its falling edge. Care must be taken to avoid bus contention in this type of operation. Data input must be valid for tDVWH before the rising edge of Write Enable, or for tDVEH before the rising edge of E1 or for tDVBH before the rising edge of UB/LB, whichever occurs first, and remain valid for tWHDX, tEHDX and tBHDX respectively.
