No. 0.0 512K X 18, 256K X 36 LVTTL, Flow-through ZeBLTM SRAM History Initial issue Issue Date July 12, 2005 Remark Preliminary PRELIMINARY (July, 2005, Version 0.0) AMIC Technology, Corp. A67P93181/A67P83361 Preliminary Features Fast access time: 6.5/7.5/8.5 ns (153, 133, 117 MHz) Zero Bus Latency between READ and WRITE cycles allows 100% bus utilization Signal +2.5V ± 5% power supply Individual Byte Write control capability Clock enable ( CEN ) pin to enable clock and suspend operations Clock-controlled and registered address, data and control signals Registered output for pipelined applications Three separate chip enables allow wide range of options for CE control, address pipelining Internally self-timed write cycle Selectable BURST mode (Linear or Interleaved) SLEEP mode (ZZ pin) provided Available in 100 pin LQFP package 512K X 18, 256K X 36 LVTTL, Flow-through ZeBLTM SRAM General Description The AMIC Zero Bus Latency (ZeBLTM) SRAM family employs high-speed, low-power CMOS designs using an advanced CMOS process. The A67P93181, A67P83361 SRAMs integrate a 512K X 18, 256K X 36 SRAM core with advanced synchronous peripheral circuitry and a 2-bit burst counter. These SRAMs are optimized for 100 percent bus utilization without the insertion of any wait cycles during Write-Read alternation. The positive edge triggered single clock input (CLK) controls all synchronous inputs passing through the registers. The synchronous inputs include all address, all data inputs, active low chip enable ( CE ), two additional chip enables for easy depth expansion (CE2, CE2 ), cycle start input (ADV/ LD ), synchronous clock enable ( CEN ), byte write enables ( BW1 , BW2 , BW3 , BW4 ) and read/write (R/ W ). Asynchronous inputs include the output enable ( OE ), clock (CLK), SLEEP mode (ZZ, tied LOW if unused) and burst mode (MODE). Burst Mode can provide either interleaved or linear operation, burst operation can be initiated by synchronous address Advance/Load (ADV/ LD ) pin in Low state. Subsequent burst address can be internally generated by the chip and controlled by the same input pin ADV/ LD in High state. Write cycles are internally self-time and synchronous with the rising edge of the clock input and when R/ W is Low. The feature simplified the write interface. Individual Byte enables allow individual bytes to be written. BW1 controls I/Oa pins; BW2 controls I/Ob pins; BW3 controls I/Oc pins; and BW4 controls I/Od pins. Cycle types can only be defined when an address is loaded. The SRAM operates from a +2.5V power supply, and all inputs and outputs are LVTTL-compatible. The device is ideally suited for high bandwidth utilization systems. PRELIMINARY (July, 2005, Version 0.0) 2 AMIC Technology, Corp.

Pins 84 are reserved as address bits for higher-density 18Mb ZeBL SRAMs, respectively. A0 and A1 are the two lest significant bits (LSB) of the address field and set the internal burst counter if burst is desired. Synchronous Byte Write Enables : These active low inputs allow individual bytes to be written when a WRITE cycle is active and must meet the setup and hold times around the rising edge of CLK. BYTE WRITEs need to be asserted on the same cycle as the address, BWs are associated with addresses and apply to subsequent data. BW1 controls I/Oa pins; BW2 controls I/Ob pins; BW3 controls I/Oc pins; BW4 controls I/Od pins. Clock : This signal registers the address, data, chip enables, byte write enables and burst control inputs on its rising edge. All synchronous inputs must meet setup and hold times around the clock’s rising edge. Synchronous Chip Enable : This active low input is used to enable the device. This input is sampled only when a new external address is loaded (ADV/ LD LOW). Synchronous Chip Enable : This active low input is used to enable the device and is sampled only when a new external address is loaded (ADV/ LD LOW). This input can be used for memory depth expansion. Synchronous Chip Enable : This active high input is used to enable the device and is sampled only when a new external address is loaded (ADV/ LD LOW). This input can be used for memory depth expansion. 89 89 CLK 98 98 CE 92 92 CE2 97 97 CE2 86 86 OE Output Enable : This active low asynchronous input enables the data I/O output drivers. Synchronous Address Advance/Load : When HIGH, this input is used to advance the internal burst counter, controlling burst access after the external address is loaded. When HIGH, R/ W is ignored. A LOW on this pin permits a new address to be loaded at CLK rising edge. Synchronous Clock Enable : This active low input permits CLK to propagate throughout the device. When HIGH, the device ignores the CLK input and effectively internally extends the previous CLK cycle. This input must meet setup and hold times around the rising edge of CLK. 85 85 ADV/ LD 87 87 CEN PRELIMINARY (July, 2005, Version 0.0) 6 AMIC Technology, Corp.

When active, all other inputs are ignored. Read/Write : This active input determines the cycle type when ADV/ LD is LOW. This is the only means for determining READs and WRITEs. READ cycles may not be converted into WRITEs (and vice versa) other than by loading a new address. A LOW on this pin permits BYTE WRITE operations and must meet the setup and hold times around the rising edge of CLK. Full bus width WRITEs occur if all byte write enables are LOW. SRAM Data I/O : Byte “a” is I/Oa pins; Byte “b” is I/Ob pins; Byte “c” is I/Oc pins; Byte “d” is I/Od pins. Input data must meet setup and hold times around CLK rising edge. 88 88 R/ W 74, 73, 72, 69, 68 63, 62, 59, 58 24, 23, 22, 19, 18 13, 12, 9, 8 31 52, 53, 56, 57, 58, 59, 62, 63, 51 68, 69, 72, 73, 74, 75, 78, 79, 80 2, 3, 6, 7, 8, 9, 12, 13,1 18, 19, 22, 23, 24, 25, 28, 29, 30 31 I/Oa I/Ob I/Oc I/Od MODE Mode: This input selects the burst sequence. A LOW on this pin selects linear burst. NC or HIGH on this pin selects interleaved burst. Do not alter input state while device is operating. No Connect : These pins can be left floating or connected to GND to minimize thermal impedance. 1, 2, 3, 6, 7, 25, 28, 29, 30, 38, 39, 42,43 51, 52, 53, 56, 57, 75, 78, 79, 95, 96 15, 16, 41, 65, 91 4, 11, 20, 27, 54, 61, 70, 77 14, 17, 40, 66, 90 5,10,21,26, 55,60,71,76 38,39,42,43 NC 15, 16, 41, 65, 91 4, 11, 20, 27, 54, 61, 70, 77 14, 17, 40, 66, 90 5,10,21,26, 55,60,71,76 VCC VCCQ VSS VSSQ Power Supply Isolated Output Buffer Supply Ground : GND.

Continue Burst cycles, whether READ or WRITE, use the same control inputs. The type of cycle performed (READ or WRITE) is chosen in the initial Begin Burst cycle. A Continue Deselect cycle can only be entered if a Deselect cycle is executed first. 2. Dummy READ and WRITE Abort cycles can be considered NOPs because the device performs no operation. A WRITE Abort means a WRITE command is given, but no operation is performed. 3. OE may be wired LOW to minimize the number of control signals to the SRAM. The device will automatically turn off the output drivers during a WRITE cycle. Some users may use OE when the bus turn-on and turn-off times do not meet their requirements. 4. If an Ignore Clock Edge command occurs during a READ operation, the I/O bus will remain active (Low-Z). If it occurs during a WRITE cycle, the bus will remain in High-Z. No WRITE operations will be performed during the Ignored Clock Edge cycle. 5. X means “Don’t Care.” H means logic HIGH. L means logic LOW. BWx = H means all byte write signals ( BW1, BW2 , BW3 and BW4 ) are HIGH. BWx = L means one or more byte write signals are LOW. 6. BW1enables WRITEs to Byte “a” (I/Oa pins); BW2 enables WRITEs to Byte “b” (I/Ob pins); BW3 enables WRITEs to Byte “c” (I/Oc pins); BW4 enables WRITEs to Byte “d” (I/Od pins). 7.

A67P93181/A67P83361 SLEEP Mode SLEEP Mode is a low current “Power-down” mode in which the device is deselected and current is reduced to ISB2Z. This duration of SLEEP Mode is dictated by the length of time the ZZ is in a HIGH state. After entering SLEEP Mode, all inputs except ZZ become disabled and all outputs go to High-Z. The ZZ pin is asynchronous, active high input that causes the device to enter SLEEP Mode. When the ZZ pin becomes logic HIGH, ISB2Z is guaranteed after the time tZZI is met. Any operation pending when entering SLEEP Mode is not guaranteed to successfully complete. Therefore, SLEEP Mode (READ or WRITE) must not be initiated until valid pending operations are completed. Similarly, when exiting SLEEP Mode during tRZZ, only a DESELECT or READ cycle should be given while the SRAM is transitioning out of SLEEP Mode.
