Part Number 24AA16 24LC16B Note 1: Vcc Range 1.8-5.5 2.5-5.5 Max Clock Frequency kHz(1) 400 kHz Temp Ranges I, E

Description

The Microchip Technology Inc. a 16 Kbit Electrically Erasable PROM. The device is organized as eight blocks x 8-bit memory with a 2-wire serial interface. Low-voltage design permits operation down to 1.8V with standby and active currents of only 1 �A and 1 mA, respectively. The 24XX16 also has a page write capability for to 16 bytes of data. The 24XX16 is available in the standard 8-pin PDIP, surface mount SOIC, TSSOP and MSOP packages and is also available in the 5-lead SOT-23 package.

Not 100% tested. CB = total capacitance of one bus line in pF. As a transmitter, the device must provide an internal minimum delay time to bridge the undefined region (minimum 300 ns) of the falling edge of SCL to avoid unintended generation of START or STOP conditions. The combined TSP and VHYS specifications are due to new Schmitt Trigger inputs which provide improved noise spike suppression. This eliminates the need for a TI specification for standard operation. This parameter is not tested but ensured by characterization.
