Description:
The Microchip Technology Inc. 24AA65/24LC65/
24C65 (24XX65)* is a “smart” 8K x 8 Serial Electrically
Erasable PROM. This device has been developed for
advanced, low-power applications such as personal
communications, and provides the systems designer
with flexibility through the use of many new user-pro-
grammable features. The 24XX65 offers a relocatable
4K bit block of ultra-high-endurance memory for data
that changes frequently. The remainder of the array, or
60K bits, is rated at 1,000,000 erase/write (E/W) cycles
ensured. The 24XX65 features an input cache for fast
write loads with a capacity of eight pages, or 64 bytes.
This device also features programmable security
options for E/W protection of critical data and/or code
of up to fifteen 4K blocks. Functional address lines
allow the connection of up to eight 24XX65’s on the
same bus for up to 512K bits contiguous EEPROM
memory. Advanced CMOS technology makes this
device ideal for low-power nonvolatile code and data
applications. The 24XX65 is available in the standard
8-pin plastic DIP and 8-pin surface mount SOIJ
package.
