Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M4A5-192/96-10VC is determined by strict equivalence across the following critical parameters:

• Macrocell Count: 192 macrocells (functional logic capacity)
• I/O Pin Count: 96 I/O pins (interface capability)
• Maximum Propagation Delay: 10 ns (timing performance)
• Supply Voltage Range: 4.75V ~ 5.25V (power compatibility)
• Operating Temperature Range: 0°C ~ 70°C (thermal envelope)
• Package Type: 144-LQFP surface mount (physical and electrical compatibility)
• Programmable Architecture: In System Programmable (ISP capability)

The M4A5-192/96-10VNC qualifies as a direct substitute, maintaining identical electrical specifications and package configuration while differing only in packaging format (tray vs. tube) and product lifecycle status.

Parameter Comparison

Engineering Selection Recommendations

The M4A5-192/96-10VNC serves as the direct functional equivalent to the M4A5-192/96-10VC. Both devices share identical electrical and timing specifications, ensuring pin-for-pin and functional compatibility in circuit applications.

The primary distinction lies in product lifecycle status and regulatory compliance. The M4A5-192/96-10VC is classified as obsolete, while the M4A5-192/96-10VNC carries Last Time Buy status, indicating extended but finite availability. The M4A5-192/96-10VNC additionally achieves ROHS3 compliance, whereas the original part is RoHS non-compliant.

For new designs or system updates requiring this logic density and performance tier, the M4A5-192/96-10VNC is the appropriate selection. For legacy system maintenance where the original part specification must be preserved, the M4A5-192/96-10VC remains functionally interchangeable where inventory permits.

Frequently Asked Questions (FAQ)

Q: Can M4A5-192/96-10VNC be used as a direct replacement for M4A5-192/96-10VC in existing designs?

A: Yes. Both devices are electrically and functionally identical across all critical parameters: 192 macrocells, 96 I/O pins, 10 ns propagation delay, 4.75V–5.25V supply voltage, 0°C–70°C operating temperature, and 144-LQFP package configuration. Pin-for-pin substitution is valid.

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

A: The devices are functionally equivalent. Differences are limited to packaging format (tray vs. tube), product lifecycle stage (obsolete vs. Last Time Buy), and RoHS compliance status (non-compliant vs. ROHS3 compliant).

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

A: No. Both devices specify identical maximum propagation delay of 10 ns and operate within the same voltage and temperature ranges.

Q: What does "Last Time Buy" status mean for the M4A5-192/96-10VNC?

A: Last Time Buy indicates that Lattice Semiconductor has announced end-of-life for this device. Inventory remains available for a defined period, after which the part will no longer be manufactured or supplied.

Q: Is the 144-LQFP package identical between both parts?

A: Yes. Both parts use the same 144-pin LQFP surface mount package with 20x20 mm dimensions, ensuring mechanical and electrical compatibility on PCBs designed for either variant.

Q: Does RoHS compliance affect functional compatibility?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical function. Both parts operate identically in circuit applications.
