4 / 27 page LH28F008SA 8M (1M × 8) Flash Memory 4 PIN DESCRIPTION SYMBOL TYPE NAME AND FUNCTION A 0 - A19 INPUT ADDRESS INPUTS: For memory addresses. Addresses are internally latched during a write cycle. DQ 0 - DQ7 INPUT/OUTPUT DATA INPUT/OUTPUTS: Inputs data and commands during Command User Interface write cycles; outputs data during memory array. Status Register and Identifier read cycles. The data pins are active high and float to tri-state off when the chip is deselected or the outputs are disabled. Data is internally latched during a write cycle. CE » INPUT CHIP ENABLE: Activates the device’s control logic input buffers, decoders, and sense amplifiers. CE » is active low: CE» high deselects the memory device and reduces power consumption to standby levels. PWD INPUT POWERDOWN: Puts the device in deep powerdown mode. PWD is active low; PWD high gates normal operation. PWD also locks out block erase or byte write operations when active low, providing data protection during power transitions. OE » INPUT OUTPUT ENABLE: Gates the device’s outputs through the data buffers during a read cycle. OE » is active low. WE INPUT WRITE ENABLE: Controls writes to the Command User Interface and array blocks. WE is active low. Addresses and data are latched on the rising edge of the WE Pulse. RY »/BY » OUTPUT READY/BUSY : Indicates the status of the internal Write State Machine. When low, it indicates that the WSM is performing a block erase or byte write operation. RY »/BY » high indicates that the WSM is ready for new commands, block erase is suspended or the device is in deep powerdown mode. RY »/BY»is always active and does NOT float to tri-state off when the chip is deselected or data outputs are disabled. V PP SUPPLY BLOCK ERASE/BYTE WRITE POWER SUPPLY: for erasing blocks of the array or writing bytes of each block. NOTE: With V PP < VPPLMAX, memory contents cannot be altered. V CC DEVICE POWER SUPPLY: (5 V ±10%, 5 V ±5%) GND SUPPLY GROUND |
