Voltage Operating Range: V to V. – Peak write current 3 mA at V. – Maximum read current μA at V. – Standby current 1 μA, typical. • Industry. The 24LC65 offers a relocatable 4K bit block of ultra-high-endurance memory for data that changes frequently. The remain- der of the array, or 60K bits, is rated. bits contiguous EEPROM memory. Advanced CMOS technology makes this device ideal for low-power non- volatile code and data applications. The 24LC65 is.

The 24LC65 has a sophisticated mechanism for write-protecting portions of the array. Why i can disable it?
Wed Feb 04, 9: Corporate Product Selector Guide. It uses delays, instead. This write protect function is programmable and allows the user to protect contiguous 4K blocks.
Electronic Solutions for Medical and Fitness. Only show products with samples. To invoke the security option, a write command is sent to the device with the leading bit bit 7 of the first address byte set to a 1 Figure I use the 24lc65 and i tried to put your function for my eeprom. AN – Interfacing I2C?
For pricing and availability, contact Microchip Local Sales. The user sets the security option by sending to the device the starting block number for the protected region and the number of blocks to be protected.
Please contact 24l65 office if device weight is not available. CCS does not monitor this forum on a regular basis. If it still doesn’t work after you check those connections, then try this older CCS driver for the datadheet Display posts from previous: The Microchip Technology Inc.
24LC65 Datasheet PDF
In Production View Datasheet Features: Fri Feb 06, 1: I can’t use 24lc because i only have 24lc65 in my possession. Wed Feb 04, Designers of Serial Ratasheet applications can enjoy the increased productivity, reduced time to market and rock-solid design that only a well thought out development system can provide.
Look at the schematic shown in this post. I try to use external eeprom 24ld65 with pic16f and functions from compiler doesn’t work.
It doesn’t do ACK polling. Maybe it doesn’t function. Advanced CMOS technology makes this device ideal for low-power nonvolatile code and data applications. I’ve tried your functions and the functions of the ccs compilator and anyone seems to be correct.
Microchip – datasheet pdf
My circuit datasheef the same as yours with pull-up. Application Notes Download All. Bits of the first address byte define the starting block number for the protected region. Buy from the Microchip Store. The 24XX65 offers a relocatable 4K bit block of ultra-high-endurance memory for data that changes frequently. Fri Feb 06, For example, if the starting block number is to be set to 5, the first address byte would be 1XXX.
Send them to support ccsinfo. The 24XX65 features an input cache for fast write loads with a capacity of eight pages, or 64 bytes. Please do not post bug Reports on this forum.
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-programmable features. Maybe it doesnt function.
