Description

The Microchip Technology Inc. 24FC65 is a “smart” 8K 8x 8 Serial Electrically Erasable PROM (EEPROM) with a high-speed 1MHz SE2.bus whose protocol is functionally equivalent to the industry-standard I2C bus.

This device has been developed for advanced applications such as personal communications, and provides the systems designer with flexibility through the use of many new user-programmable features. The device 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 guaranteed. The IC 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.

Features : 

• 1 MHz SE2.bus two wire protocol

• Up to eight devices may be connected to the same bus for up to 512K bits total memory

• Programmable block security options

• Programmable endurance options

• Schmitt trigger inputs for noise suppression

• Self-timed ERASE and WRITE cycles
