DS80C323-ECD Equivalent & Substitute Parts

Part Overview

The DS80C323-ECD is an 8051 80C microcontroller IC manufactured by Analog Devices Inc./Maxim Integrated. This 8-bit embedded processor operates at 18MHz with ROMless architecture and is housed in a 44-TQFP (10x10) surface mount package. The device is classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing system support and new designs requiring this microcontroller class.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DS80C323-ECD is determined by strict alignment across the following critical parameters:

• Core processor architecture (8051)
• Core size (8-Bit)
• Operating frequency (18MHz)
• Memory configuration (ROMless, 256 x 8 RAM)
• I/O count (32 pins)
• Supply voltage range (2.7V ~ 5.5V)
• Package type (44-TQFP)
• Connectivity interfaces (EBI/EMI, SIO, UART/USART)
• Peripheral features (Power-Fail Reset, WDT)

The DS80C323-ECD+ meets all substitution criteria as a direct equivalent. The primary distinction is product status and packaging configuration, with the substitute part classified as active and supplied in Tray packaging.

Parameter Comparison

Engineering Selection Recommendations

The DS80C323-ECD+ is the direct functional equivalent for the obsolete DS80C323-ECD. Selection of the substitute part is supported by:

• Identical electrical specifications across all core parameters
• Active product status ensuring continued availability and manufacturing support
• ROHS3 compliance, meeting current environmental and regulatory requirements
• Equivalent package footprint and pinout compatibility
• Same supply voltage range and operating temperature specifications

The transition from DS80C323-ECD to DS80C323-ECD+ requires no circuit redesign or firmware modification, as all functional and electrical characteristics remain unchanged.

Frequently Asked Questions (FAQ)

Q: Can DS80C323-ECD+ be used as a direct replacement for DS80C323-ECD?

A: Yes. Both parts share identical core processor architecture, clock speed, memory configuration, I/O count, package type, and electrical specifications. No circuit modifications are required.

Q: What is the primary difference between these two part numbers?

A: The DS80C323-ECD+ is the active production variant with ROHS3 compliance and Tray packaging, while the DS80C323-ECD is classified as obsolete. Functionally, they are equivalent.

Q: Are the pin configurations identical?

A: Yes. Both parts use the 44-TQFP (10x10) package with identical pinout and I/O assignments.

Q: Does the RoHS compliance difference affect compatibility?

A: No. ROHS3 compliance of the substitute part indicates adherence to current environmental standards and does not alter electrical or functional performance relative to the main part.

Q: What packaging options are available?

A: The DS80C323-ECD+ is supplied in Tray packaging. Packaging configuration does not affect component functionality or circuit compatibility.

Q: Are there any firmware or software considerations for substitution?

A: No. Both parts execute identical 8051 instruction sets and support the same firmware without modification.
