... DESCRIPTION The Microchip Technology Inc. 24AA04/ bit or 8K bit Electrically Erasable PROM. The device is orga- nized as two or four blocks of 256 x 8-bit memory with a two wire serial interface. Low voltage design permits operation down to 1.8 volts with standby and active cur- rents of only 3 A and 1 mA respectively. The 24AA04/ 08 also has a page-write capability for bytes of data ...

... T WR Endurance 24AA04 — 24AA08 Note 1: Not 100% tested total capacitance of one bus line in pF transmitter, the device must provide an internal minimum delay time to bridge the undefined region (min- imum 300 ns) of the falling edge of SCL to avoid unintended generation of START or STOP conditions. ...

... The next three bits of the control byte are the block select bits (B2, B1, B0 don't care for both the 24AA04 and 24AA08 don't care for the 24AA04. They are used by the master device to select which of the two or four 256 word blocks of memory are to be accessed. These bits are in effect the most signifi ...

... To provide sequential reads the 24AA04/08 contains an internal address pointer which is incremented by one at the completion of each operation. This address pointer allows the entire memory contents to be serially read during one operation. 7.4 Noise Protection The 24AA04/08 employs a V ...

... 8.3 WP This pin must be connected to either V If tied to Vss, normal memory operation is enabled (read/write the entire memory). If tied WRITE operations are inhibited. The CC entire memory will be write-protected. Read operations for 400 are not affected. This feature allows the user to use the 24AA04/ serial ROM when WP is enabled (tied to Vcc) ...
