A63L83361 256K X 36 Bit Synchronous High Speed SRAM with Burst Counter and Flow-through Data Output Preliminary Document Title 256K X 36 Bit Synchronous High Speed SRAM with Burst Counter and Flowthrough Data Output Revision History Rev. No. 0.0 PRELIMINARY History Issue Date Remark Initial issue July 14, 2005 Preliminary (July, 2005, Version 0.0) AMIC Technology, Corp. A63L83361 Preliminary 256K X 36 Bit Synchronous High Speed SRAM with Burst Counter and Flow-through Data Output Features Selectable BURST mode SLEEP mode (ZZ pin) provided Available in 100-pin LQFP package Industrial operating temperature range: -45°C to +125°C for -I series Fast access times: 6.5/7.5/8.0 ns(153/133/117 MHz) Single 3.3V±5% power supply Synchronous burst function Individual Byte Write control and Global Write Three separate chip enables allow wide range of options for CE control, address pipelining General Description Burst operations can be initiated with either the address status processor ( ADSP ) or address status controller ( ADSC ) input pin. Subsequent burst sequence burst addresses can be internally generated by the A63L83361 and controlled by the burst advance ( ADV ) pin. Write cycles are internally self-timed and synchronous with the rising edge of the clock (CLK). This feature simplifies the write interface. Individual Byte enables allow individual bytes to be written. BW1 controls I/O1 - I/O9, BW2 controls I/O10 - I/O18, BW3 controls I/O19 - I/O27, and BW4 controls I/O28 - I/O36, all on the condition that BWE is LOW. GW LOW causes all bytes to be written. The A63L83361 is a high-speed SRAM containing 9M bits of bit synchronous memory, organized as 256K words by 36 bits. The A63L83361 combines advanced synchronous peripheral circuitry, 2-bit burst control, input registers, output buffer and a 256K X 36 SRAM core to provide a wide range of data RAM applications. The positive edge triggered single clock input (CLK) controls all synchronous inputs passing through the registers. Synchronous inputs include all addresses (A0 A17), all data inputs (I/O1 - I/O36 ), active LOW chip enable ( CE ), two additional chip enables (CE2, CE2 ), burst control inputs ( ADSC , ADSP , ADV ), byte write enables ( BWE , BW1 , BW2 , BW3 , BW4 ) and Global Write ( GW ). Asynchronous inputs include output enable ( OE ), clock (CLK), BURST mode (MODE) and SLEEP mode (ZZ). PRELIMINARY (July, 2005, Version 0.0) 1 AMIC Technology, Corp.

A63L83361 Notes: 1. X = "Disregard", H = Logic High, L = Logic Low. 2. WRITE = L means: 1) Any BWx ( BW1 , BW2 , BW3 , or BW4 ) and BWE are low or 2) GW is low. 3. All inputs except OE must be synchronized with setup and hold times around the rising edge (L-H) of CLK. 4. For write cycles that follow read cycles, OE must be HIGH before the input data request setup time and held HIGH throughout the input data hold time. 5. ADSP LOW always initiates an internal Read at the L-H edge of CLK. A Write is performed by setting one or more byte write enable signals and BWE LOW or GW LOW for the subsequent L-H edge of CLK.

A63L83361 Notes: 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. All voltages refer to GND. Overshoot: VIH ≤ +2V for t ≤ tKC/2. Undershoot: VIL ≥ -0.7V for t ≤ tKC/2. Power-up: VIH ≤ +2 and VCC ≤ 1.7V for t ≤ 200ms ICC1 is given with no output current. ICC1 increases with greater output loading and faster cycle times. Test conditions assume the output loading shown in Figure 1, unless otherwise specified. For output loading, CL = 5pF, as shown in Figure 2. Transition is measured ±150mV from steady state voltage. At any given temperature and voltage condition, tKQHZ is less than tKQLZ and tOEHZ is less than tQELZ. A WRITE cycle is defined by at least one Byte Write enable LOW and ADSP HIGH for the required setup and hold times. A READ cycle is defined by all byte write enables HIGH and ( ADSC or ADV LOW) or ADSP LOW for the required setup and hold times. OE has no effect when a Byte Write enable is sampled LOW. This is a synchronous device. All addresses must meet the specified setup and hold times for all rising edges of CLK when either ADSP or ADSC is LOW and the chip is enabled. All other synchronous inputs must meet the setup and hold times with stable logic levels for all rising edges of clock (CLK) when the chip is enabled. Chip enable must be valid at each rising edge of CLK when either ADSP or ADSC is LOW to remain enabled. The load used for VOH, VOL testing is shown in Figure 2. AC load current is higher than the given DC values. AC I/O curves are available upon request. "Device Deselected" means device is in POWER-DOWN mode, as defined in the truth table. "Device Selected" means device is active (not in POWER-DOWN mode). MODE pin has an internal pulled-up, and ZZ pin has an internal pulled-down. All of then exhibit an input leakage current of 10µA. Snooze (ZZ) input is recommended that users plan for four clock cycles to go into SLEEP mode and four clocks to emerge from SLEEP mode to ensure no data is lost.
