CS8900A variants from Cirrus Logic Inc.
CS8900A Overview
What changes between part numbers, and what to check before you lock the BOM — Integrated Circuits (ICs).
CS8900A is a Cirrus Logic Inc. order-code family — not a single orderable MPN. This page lists 2 variants that share the same core device but differ in suffix fields (package, grade, reel/tube, electrical bin, etc.). Pick the exact full part number; substituting within the family without checking the datasheet often causes assembly or spec mismatches.
Package: 100-LQFP | Supply Voltage: 3V, 5V | Interface: ISA | Operating Temperature: 0°C ~ 70°C Other listed variants describe: Package: 100-LQFP | Supply Voltage: 3V, 5V | Interface: ISA | Operating Temperature: -40°C ~ 85°C.
Across listed variants, watch these parameters: packages: 100-LQFP.
Suffix examples in this family: CQ3Z, IQZ. The characters after the base number usually encode package, temperature, or performance grade — compare the variant table column-by-column rather than assuming pin-compatible drops-in.
Example MPNs: CS8900A-CQ3Z, CS8900A-IQZ.
Key Features
- Footprint / package: 100-LQFPSingle package option across listed variants; still confirm reel vs tube suffix if you auto-insert.
- Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
- 2 distinct suffix patternsExamples: CQ3Z, IQZ. Decode suffix meaning in the ordering notes under the variant table.
Target Applications
- Integrated Circuits (ICs) — design-in and field replacement
- BOM scrub where only the base prefix is known but suffix is TBD
- Second-source checks when the original MPN is constrained

| Part Number | Description | Package Type | Manufacturer | Lifecycle | RoHS | Availability | Action |
|---|---|---|---|---|---|---|---|
| CS8900A-CQ3Z | Package: 100-LQFP | Supply Voltage: 3V, 5V | Interface: ISA | Operating Temperature: 0°C ~ 70°C | 100-LQFP | Cirrus Logic Inc. | Active | Compliant | In Stock | |
| CS8900A-IQZ | Package: 100-LQFP | Supply Voltage: 3V, 5V | Interface: ISA | Operating Temperature: -40°C ~ 85°C | 100-LQFP | Cirrus Logic Inc. | Active | Compliant | In Stock |
Ordering Code Differences
How suffixes on CS8900A map to package, grade, and reel options.
CS8900A uses a shared prefix; characters after the prefix encode orderable options. Two lines with the same prefix are not drop-in replacements unless the differing columns match your need.
Suffixes seen here: CQ3Z, IQZ.
Full MPN examples: CS8900A-CQ3Z, CS8900A-IQZ.
Tip: photograph or copy the reel label — reel diameter, QTY per reel, and moisture sensitivity level (MSL) are often suffix-driven and won't show in the schematic.
How to Choose the Right CS8900A Integrated Circuits (ICs)
Match the footprint first
Packages here: 100-LQFP. Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For CS8900A, a suffix with lower voltage or current rating will not survive the same circuit without recalculation.
Temp grade letter matters
Commercial (0–70 °C) and industrial (−40–85 °C+) suffixes look similar in the prefix — confirm ambient + self-heating, not just the first page of the datasheet.
Copy the full MPN
Do not BOM only "CS8900A" — include the full suffix (e.g. CQ3Z, IQZ). RFQ with reel/tube preference and required date code.
