Memory IC datasheet and documents for AT49F002N-70JI

AT49F002N-70JI

Memory IC Overview

The AT49F002N-70JI is a 5-volt only in-system reprogrammable Flash memory manufactured by Microchip Technology. It provides 2 megabits of storage organized as 262,144 words by 8 bits. The device features a fast read access time of 70 ns and operates within a commercial temperature range of 0°C to 70°C. It utilizes a sector architecture including a 16K byte boot block with programming lockout capability, two 8K byte parameter blocks, and two main memory blocks. Key electrical specifications include an active current of 50 mA and a CMOS standby current of 100 µA.

Memory IC Feature Summary

Supports single-voltage 5V operation for both reading and reprogramming without requiring high input voltages.
Includes hardware data protection mechanisms such as VCC sense inhibition and noise filters to prevent inadvertent programming.
Features a dedicated 16K byte boot block that can be permanently locked out to protect secure system code.

Memory IC Applications

In-system reprogrammable nonvolatile storage
Secure boot code storage with lockout protection
Industrial and commercial embedded systems

Memory IC Procurement Notes

Verify the specific suffix 'JI' corresponds to the industrial temperature range (-40°C to 85°C) and 32-pin PDIP package as listed in the ordering information. Confirm the manufacturer origin, noting historical Atmel branding may appear on older documentation. Ensure compatibility with 5V logic levels and check for moisture sensitivity requirements during handling.

Memory IC Selection Notes

Select this component when a 5V-only Flash memory with in-system programmability is required. The 70 ns access speed suits moderate-speed applications. Consider the sector architecture for firmware updates where a protected boot block is necessary. Verify package availability in 32-pin PDIP if through-hole mounting is preferred over surface mount options.

Memory IC Part Context

This part belongs to the AT49F002 series of 2-megabit Flash memories. Variants exist with different access times (55, 90, 120 ns) and packages (PLCC, TSOP, VSOP). The 'N' indicates the presence of a RESET pin, while 'T' denotes a different boot block address location. The 'J' signifies the plastic DIP package, and 'I' indicates the industrial temperature grade.
