PCN / EOL Notification PCN Number: CC142904A (Revised 3/17/16) Notification Date*: December 27, 2013 See Changes in Blue Text Title: AT24C01C to AT24C01D — 1-Kbit I2C-Compatible (Two Wire Interface) Industrial Temperature Grade (-40°C to 85°C) Serial EEPROM Process Optimization and Device Enhancement Note: Continued Support of 5V 1-Kbit Two-Wire Interface Industrial Temperature Grade (-40 to 85C) EEPROM device (AT24C01C) Product Identification: AT24C01C (1.7 to 5.5V); AT24C01D (1.7 to 3.6V): All Packages Industrial Temp. Grade (-40C to +85C) Reason for Change: Material / Composition Manufacturing Location Processing / Manufacturing Quality / Reliability Design / Firmware Logistics Datasheet Other: Change Description: Atmel launched a new low voltage (1.7V- 3.6V) variant of the I2C 2-Kbit EEPROM Industrial Grade (-40C to +85C) device AT24C01D in 2014. The new, low voltage device has significant improvements and advantages over the existing wide voltage (1.7V – 5.5V) device AT24C01C with respect to power consumption, endurance, and noise suppression. With a growing number of MCUs, SoCs, and ASICs migrating to lower supply voltages as a result of process lithography reductions, and to reduce power consumption, Atmel developed the AT24C01D to specifically work with a 1.7V to 3.6V supply. However Atmel recognizes that some applications might still require a 5V supply voltage, so this addendum to the PCN is to confirm that Atmel will continue to support and produce the wide voltage device AT24C01C. Therefore, customers may continue with the AT24C01C in all applications that use 5V or 3.3V supply voltage. However, for applications tailored towards low voltage operation (e.g. 1.8V, 3.0V, etc.), Atmel recommends customers migrate to the enhanced performance of the AT24C01D. (See table below for details of AT24C01D’s low voltage enhancements.) Atmel Corporation 1600 Technology Drive San Jose, CA 95110 USA QF-8005 Rev. 14 07/23/2013 Page 1 of 5 PCN/EOL NO.
