PCN / EOL Notification PCN Number: CC144901 Notification Date*: December 18, 2014 Title: AT24C32D to AT24C32E — 32-Kbit I2C-Compatible (Two Wire Interface) Industrial Temperature Grade (-40°C to 85°C) Serial EEPROM Process Optimization and Device Enhancement Product Identification: All package options of the Industrial Temperature Grade (-40°C to +85°C) version of the AT24C32D Reason for Change: Material / Composition Manufacturing Location Processing / Manufacturing Quality / Reliability Design / Firmware Logistics Datasheet Other: Change Description: Atmel has redesigned and improved its Industrial Temperature Grade (-40°C to +85°C) version of the 32-Kbit I2C-compatible Serial EEPROM and optimized the associated device’s process. These changes have been made to enhance device performance and robustness. As a result, the Industrial Temperature Grade version of the AT24C32D is being replaced by the AT24C32E (please note the revision letter change from “D” to “E” in the base part number — see Table 2 for a list of full catalog part numbers). The AT24C32E is pin-to-pin and functionally backward compatible to the AT24C32D with the following exceptions and enhancements. Supply Voltage (VCC) Range With a growing number of MCUs, SoCs, and ASICs migrating to lower supply voltages as a result of process lithography reductions, and as the electronics industry in general also moves to lower supply voltages to reduce power consumption, Atmel developed the next-generation AT24C32E to enhance performance for these lower voltage requirements. Unlike the AT24C32D devices that operate over a 1.7V to 5.5V voltage range, the AT24C32E devices have been designed to operate from a 1.7V to 3.6V supply. As a result, the AT24C32E has significant improvements and advantages over the AT24C32D devices with respect to power consumption, endurance, and noise suppression (see Table 1 for all differences). For applications operating at voltage levels above 3.6V, please contact Atmel ([email protected]) for details on continued availability of the AT24C32D and to request an exception to the Last Time Buy and Last Ship dates.
