DESCRIPTION
The Microchip Technology Inc. 24C08B/16B is an 8K or
16K bit Electrically Erasable PROM intended for use in
extended/automotive temperature ranges. The device
is organized as four or eight blocks of 256 x 8-bit mem-
ory with a 2-wire serial interface. The 24C08B/16B also
has a page-write capability for up to 16 bytes of data.
The 24C08B/16B is available in the standard 8-pin DIP
and both 8-lead and 14-lead surface mount SOIC pack-
ages.
I2C is a trademark of Philips Corporation.
