NXP Semiconductors S912XEQ
S912XEQ variants from NXP Semiconductors
S912XEQ Overview
What changes between part numbers, and what to check before you lock the BOM — Microcontrollers.
S912XEQ is a NXP Semiconductors order-code family — not a single orderable MPN. This page lists 10 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.
IC MCU 16BIT 384KB FLASH 144LQFP Other listed variants describe: IC MCU 16BIT 512KB FLASH 112LQFP; Package: 112-LQFP | Mounting Type: Surface Mount | Operating Temperature: -40°C ~ 105°C (TA) | Supplier Device Package: 112-LQFP (20x20) | Peripherals: LVD, POR, PWM, WDT | Number of I O: 91.
Across listed variants, watch these parameters: packages: 112-LQFP.
Suffix examples in this family: 384F1VAGR, 512ACALR, 512AVALR, 512BCAAR, 512BMAAR, 512BMAG, 512F1MAA, 512J3MAAR. 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: S912XEQ384F1VAGR, S912XEQ512ACALR, S912XEQ512AVALR, S912XEQ512BCAAR, S912XEQ512BMAAR, S912XEQ512BMAG.
Key Features
- Footprint / package: 112-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.
- 10 distinct suffix patternsExamples: 384F1VAGR, 512ACALR, 512AVALR, 512BCAAR, 512BMAAR (+5 more). Decode suffix meaning in the ordering notes under the variant table.
Target Applications
- Microcontrollers — 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

Ordering Code Differences
How suffixes on S912XEQ map to package, grade, and reel options.
S912XEQ 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: 384F1VAGR, 512ACALR, 512AVALR, 512BCAAR, 512BMAAR, 512BMAG, 512F1MAA, 512J3MAAR, 512J3MAG, 512J3MAGR.
Full MPN examples: S912XEQ384F1VAGR, S912XEQ512ACALR, S912XEQ512AVALR, S912XEQ512BCAAR, S912XEQ512BMAAR.
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 S912XEQ Microcontrollers
Match the footprint first
Packages here: 112-LQFP. Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For S912XEQ, 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 "S912XEQ" — include the full suffix (e.g. 384F1VAGR, 512ACALR, 512AVALR). RFQ with reel/tube preference and required date code.
