Key Parameters

Substitute Part Grouping Explanation

Substitution of the Z8619340ASC is determined by strict equivalence across the following electrical and mechanical parameters:

• Core processor architecture (Z8)
• Core size (8-Bit)
• Operating frequency (40MHz)
• Program memory configuration (ROMless)
• RAM capacity (444 x 8)
• I/O pin count (32)
• Supply voltage range (4.5V ~ 5.5V)
• Connectivity interface (UART/USART)
• Package type (64-LQFP)
• Mounting configuration (Surface Mount)
• Operating temperature range (0°C ~ 70°C)

The Z8619340ASG meets all these criteria and qualifies as a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The Z8619340ASG is the direct substitute for the Z8619340ASC. Both components share identical electrical and mechanical specifications across all functional parameters. The primary distinction is product status: the Z8619340ASC is obsolete, while the Z8619340ASG maintains active status with current manufacturing support.

The Z8619340ASG additionally provides ROHS3 compliance, whereas the Z8619340ASC is RoHS non-compliant. Both components maintain identical REACH status (REACH Unaffected) and moisture sensitivity classification (MSL 3, 168 Hours).

For new designs or system refreshes, the Z8619340ASG is the appropriate selection due to its active product status and enhanced regulatory compliance posture.

Frequently Asked Questions (FAQ)

Q: Are Z8619340ASC and Z8619340ASG pin-compatible?

A: Yes. Both components utilize the 64-LQFP package with identical pin assignments, I/O configuration (32 pins), and electrical characteristics. Direct PCB substitution is supported without layout modification.

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

A: The Z8619340ASG is the active production variant of the Z8619340ASC. The primary differences are product lifecycle status (active versus obsolete) and RoHS compliance classification (ROHS3 Compliant versus RoHS non-compliant). All functional and electrical parameters remain identical.

Q: Can I use Z8619340ASG in place of Z8619340ASC in existing designs?

A: Yes. The Z8619340ASG is a direct functional equivalent with no design changes required. The component operates identically across all specified electrical parameters, supply voltage, operating temperature range, and I/O configuration.

Q: Why is the Z8619340ASC classified as obsolete?

A: Zilog has transitioned this product line to the Z8619340ASG variant. The obsolete designation indicates that the Z8619340ASC is no longer in active production, and the Z8619340ASG represents the current manufacturing standard.

Q: Are there any compliance considerations when switching from Z8619340ASC to Z8619340ASG?

A: The Z8619340ASG provides ROHS3 compliance, which may be advantageous for systems subject to RoHS regulatory requirements. Both components maintain identical REACH status and moisture sensitivity specifications.
