Notes: 1. H means logic HIGH, L means logic LOW. x means H or L. Write = L means any one or more byte write enable signals (BW0, BW1, BW2 or BW3) and BWE are LOW or GW is LOW. Write = H means all byte write enable signals and GW are HIGH. 2. BW0 enables write to Byte0 (DQ0 to DQ7). BW1 enables write to Byte1 (DQ8 to DQ15). BW2 enables write to Byte2 (DQ16 to DQ23). BW3 enables write to Byte3 (DQ24 to DQ31). 3. All inputs except OE must meet setup and hold times around the rising edge (LOW to HIGH) of CLK. 4. Wait states are inserted by suspending burst. 5. For a write operation following a read operation, OE must be HIGH before the input data required setup time and hold HIGH throughout the input data hold time. 6. 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 LH edge of CLK. Refer to WRITE timing diagram for clarification.

Notes: 1. Transition is measured 200mV from steady-state voltage with load of FigureB. This parameter is sampled. 2. A READ cycle is defined by byte write enables all HIGH or ADSP LOW for the required setup and hold times. A WRITE cycle is defined by at least one byte write enable LOW and ADSP HIGH for the required setup and hold times. 3. This is a synchronous device. All address must meet the specified setup and hold times for all rising edges of CLK when either ADSP or ADSC is LOW and chip enabled. All other Synchronous inputs must meet the setup and hold times with stable logic levels for all rising edges of clock (CLK) when chip is enabled. Chip enable must be valid at each rising edge of CLK (when either ADSP or ADSC is LOW) to remain enabled. 4. OE is a " H or L " when a byte write enable is sampled LOW.

Detailed Pin Description
LQFP pin number(s) Symbol Type Description Input Synchronous Address Inputs: These inputs are registered and must meet setup and hold times around the rising edge of CLK. Synchronous Byte Write Enables: These active LOW inputs allow individual bytes to be written and must meet the setup and hold times around the rising edge of CLK. A byte write enable is LOW for a WRITE cycle and HIGH for a READ cycle. BW0 controls DQ0 to DQ7. BW1 controls DQ8 to DQ15. BW2 controls DQ16 to DQ23. BW3 controls DQ24 to DQ31. Data I/O are tri-stated if any of these four inputs are LOW. Synchronous Global Write: This active LOW input allows a full 32 bit Write to occur independent of the BWE and BWi lines and must meet the setup and hold times around the rising edge of CLK. System must connect pin to VDD when not used. Synchronous Byte Write Enable: This active LOW input permits byte write operations and must meet the setup and hold times around the rising edge of CLK. System must connect pin to VSS when not used. Clock: This signal latches 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 Enables: This active LOW input is used to enable the device and conditions internal use of ADSP. This input is sampled only when a new external address is load. Synchronous Chip Enable: This active LOW input is used to enable the device. This input is sampled only when a external address is loaded. This input can be used for memory depth expansion. Synchronous Chip Enable: This active HIGH input is used to enable the device. This input sampled only when a new external address is load. This input can be used for memory depth expansion. Output Enable: This active LOW asynchronous input enables the data I/O output drivers. Synchronous Address Advance: This active LOW input is used to advance the internal burst counter, controlling burst access after the external address is loaded. A HIGH on this pin effectively causes wait status to be generated (no address advance). This pin must be HIGH at the rising edge of the first clock after an ADSP cycle is initiated if a write cycle is desired (to ensure use of correct address). 37, 36, 35, 34, 33, 32, A0 to A14 100, 99, 82, 81, 44, 45, 46, 47, 48 93, 94, 95, 96 BW0, BW1 BW2, BW3

Detailed Pin Description (cont)
LQFP pin number(s) 84 Symbol ADSP Type Description Input Synchronous Address Status Processor: This active LOW input interrupts any ongoing burst, causing a new external address to be latched. A READ performed using the new address, independent of the byte write enables and ADSC but dependent upon CE2 and CE2. ADSP is ignored if CE1 is HIGH. Power-down state is entered if CE2 is HIGH or CE2 is LOW. Synchronous Address Status Controller: This active LOW input interrupts any ongoing burst and causes a new external address to be latched. A READ or WRITE is performed using the new address if all chip enables are active. Powerdown state is entered if one or more chip enabled are inactive. No Connect: These signals are internally not connected.
