DS80C323-QCD/T&R Equivalent & Substitute Parts

Part Overview

The DS80C323-QCD/T&R is an 8051-based 8-bit microcontroller manufactured by Analog Devices Inc./Maxim Integrated. This ROMless embedded controller operates at 18MHz with a 256 x 8 byte RAM configuration and supports external program memory. The device integrates essential peripherals including Power-Fail Reset and Watchdog Timer functionality, with 32 I/O pins available for system integration.

The DS80C323-QCD/T&R carries an Obsolete product status. Locating equivalent or substitute components becomes necessary when original inventory is depleted or when transitioning to active production alternatives that maintain full electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the DS80C323-QCD/T&R is determined by strict alignment across the following critical parameters:

Core Architecture & Performance: The substitute must utilize the 8051 core processor, maintain 8-bit core size, and operate at 18MHz clock speed.

Memory Configuration: The substitute must feature ROMless program memory architecture with 256 x 8 byte RAM capacity.

Electrical Specifications: The substitute must support 2.7V to 5.5V supply voltage range and operate within the 0°C to 70°C temperature range.

I/O & Connectivity: The substitute must provide 32 I/O pins and maintain identical connectivity interfaces (EBI/EMI, SIO, UART/USART).

Peripheral Set: The substitute must include Power-Fail Reset and Watchdog Timer functionality.

Physical Form Factor: The substitute must use 44-LCC (J-Lead) package in surface mount configuration.

Compliance: The substitute must maintain ROHS3 compliance status.

Parameter Comparison

Engineering Selection Recommendations

The DS80C323-QCD+T&R serves as a direct substitute for the DS80C323-QCD/T&R. Both components are manufactured by Analog Devices Inc./Maxim Integrated and maintain identical electrical, mechanical, and functional specifications across all critical parameters.

The primary distinction between these parts is product lifecycle status: the original DS80C323-QCD/T&R is classified as Obsolete, while the DS80C323-QCD+T&R maintains Active status. This status difference reflects manufacturing availability and long-term supply assurance.

Both components carry ROHS3 compliance certification and identical moisture sensitivity level (MSL 3, 168 Hours), ensuring equivalent environmental and regulatory compliance for applications requiring these certifications.

Selection of the DS80C323-QCD+T&R is supported by its Active product status, which provides improved supply chain continuity and manufacturing support compared to the Obsolete original part number.

Frequently Asked Questions (FAQ)

Q: Are the DS80C323-QCD/T&R and DS80C323-QCD+T&R electrically identical?

A: Yes. Both components feature identical core processor architecture (8051), clock speed (18MHz), memory configuration (256 x 8 RAM, ROMless), I/O count (32 pins), voltage range (2.7V ~ 5.5V), operating temperature (0°C ~ 70°C), and peripheral set (Power-Fail Reset, WDT).

Q: What is the difference between these part numbers?

A: The DS80C323-QCD+T&R maintains Active product status, while the DS80C323-QCD/T&R is classified as Obsolete. The packaging designation differs slightly (QCD+ versus QCD/), but both use identical 44-LCC (J-Lead) surface mount packages.

Q: Can I use DS80C323-QCD+T&R as a direct replacement in existing designs?

A: Yes. The DS80C323-QCD+T&R is a direct substitute. All electrical specifications, pin configurations, package dimensions, and functional characteristics are identical. No design modifications are required.

Q: Are both parts RoHS compliant?

A: Yes. Both the DS80C323-QCD/T&R and DS80C323-QCD+T&R carry ROHS3 compliance certification.

Q: What is the moisture sensitivity level for these components?

A: Both components are rated MSL 3 (168 Hours), indicating identical moisture handling and storage requirements.

Q: Why would I choose the substitute part?

A: The DS80C323-QCD+T&R offers improved supply chain availability due to its Active product status. For new designs or production transitions, the Active part number ensures better long-term sourcing and manufacturing support.
