5 / 15 page  Pin Description Symbol Name Type Function A0-A22 Address Inputs Input Address Inputs are internally latched during write cycles. D0-D15 Data Input/Output Input/Output Data Input/Outputs are internally latched on write cycles. Data outputs are latched during read cycles. Data pins are active high. When the memory card is de-selected or the outputs are disabled the outputs float to tri-state. CE1, CE2 Card Enable Input Card Enable is active low. The memory card is de-selected and power consumption is reduced to standby levels when CE is high. CE activates the internal memory card circuitry that controls the high and low byte control logic of the card, input buffers, segment decoders, and associated memory devices. OE Output Enable Input Output Enable is active low and enables the data buffers through the card outputs during read cycles. WE Write Enable Input Write Enable is active low and controls the write function to the memory array. The target address is latched on the falling edge of the WE pulse and the appropriate data is latched on the rising edge of the pulse. VCC PC Card Power Supply PC Card Power Supply for device operation (5.0 V ± 5%) GND Ground Ground CD1, CD2 Card Detect Output When Card Detect 1 and 2 = Ground the system detects the card. WP Write Protect Output Write Protect is active high and indicates that all card write operations are disabled by the write protect switch. NC No Connect Corresponding pin is not connected internally. BVD1, BVD2 Battery Voltage Detect Output Internally pulled up. (There is no battery in the card.) REG Register Select Input Provide access to Card Information Structure in the Attribute Memory Device AT5FC008 5 |
