AT28C010-12TI EEPROM Memory IC Equivalent & Substitute Parts

Part Overview

The AT28C010-12TI is a 1Mbit parallel EEPROM memory IC manufactured by Microchip Technology, housed in a 32-TFSOP surface mount package. This device provides non-volatile memory storage with 128K x 8 organization and 120 ns access time, operating across the industrial temperature range of -40°C to 85°C.

The AT28C010-12TI is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support legacy system maintenance and production requirements.

Substitute Part Grouping Explanation

Substitution of the AT28C010-12TI is determined by strict equivalence across the following critical parameters:

  • Memory capacity (1Mbit) and organization (128K x 8)
  • Parallel interface architecture
  • Access time specification (120 ns)
  • Write cycle time (10 ms)
  • Supply voltage range (4.5V ~ 5.5V)
  • Operating temperature range (-40°C ~ 85°C)
  • Physical package compatibility (32-TFSOP surface mount)

The AT28C010-12TU qualifies as a direct substitute, maintaining identical electrical and mechanical specifications while differing only in packaging format (Tray vs. standard packaging) and product status (Active vs. Obsolete).

Engineering Selection Recommendations

The AT28C010-12TU is the direct substitute for the AT28C010-12TI. Both parts maintain identical electrical performance and physical compatibility. The primary distinction is product status: the AT28C010-12TI is obsolete while the AT28C010-12TU is active.

For new designs or ongoing production, the AT28C010-12TU is the appropriate selection due to its active status and ROHS3 compliance. For legacy system maintenance where the original AT28C010-12TI specification must be maintained, the AT28C010-12TU provides functional equivalence with improved regulatory compliance.

Both parts carry identical moisture sensitivity levels (MSL 3, 168 hours) and are subject to the same handling and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can AT28C010-12TU directly replace AT28C010-12TI in existing designs?

A: Yes. The AT28C010-12TU is electrically and mechanically equivalent to the AT28C010-12TI. Both devices share identical memory capacity, organization, access time, supply voltage, operating temperature range, and 32-TFSOP package dimensions. No circuit modifications are required.

Q: What is the difference between AT28C010-12TI and AT28C010-12TU?

A: The parts differ in product status and packaging format. The AT28C010-12TI is obsolete and supplied in standard packaging, while the AT28C010-12TU is active and supplied in Tray packaging. The AT28C010-12TU also carries ROHS3 compliance versus non-compliance for the AT28C010-12TI.

Q: Are there any timing or performance differences between these parts?

A: No. Both parts specify 120 ns access time and 10 ms write cycle time. Electrical performance is identical across all specified parameters.

Q: What are the moisture sensitivity requirements for these parts?

A: Both the AT28C010-12TI and AT28C010-12TU are classified as MSL 3 (168 hours). Standard moisture control procedures must be followed during storage, handling, and assembly.

Q: Can these parts be used interchangeably in production?

A: Yes, provided that the design accommodates the 32-TFSOP surface mount package and the 4.5V to 5.5V supply voltage range. The parallel interface and memory organization are identical, ensuring functional interchangeability.
