3 / 19 page FM24V01A Document Number: 001-90869 Rev. *H Page 3 of 19 Pinout Figure 1. 8-pin SOIC Pinout WP SCL 1 2 3 4 5 A0 8 7 6 VDD SDA A1 Top View not to scale VSS A2 Pin Definitions Pin Name I/O Type Description A0-A2 Input Device Select Address 0-2. These pins are used to select one of up to eight devices of the same type on the same two-wire bus. To select the device, the address value on the three pins must match the corresponding bits contained in the slave address. The address pins are pulled down internally. SDA Input/Output Serial Data Address. This is a bidirectional pin for the two-wire interface. It is open-drain and is intended to be wire-AND'd with other devices on the two-wire bus. The input buffer incorporates a Schmitt trigger for noise immunity and the output driver includes slope control for falling edges. An external pull-up resistor is required. SCL Input Serial Clock. The serial clock pin for the two-wire interface. Data is clocked out of the part on the falling edge, and into the device on the rising edge. The SCL input also incorporates a Schmitt trigger input for noise immunity. WP Input Write Protect. When tied to VDD, addresses in the entire memory map will be write-protected. When WP is connected to ground, all addresses are write enabled. This pin is pulled down internally. VSS Power supply Ground for the device. Must be connected to the ground of the system. VDD Power supply Power supply input to the device. |
