## Description
Impinj M750 is the Monza R6-P silicon — the user-memory tier of the M700 family. Compared to the M730 (96-bit EPC only), M750 adds 32 bits of user...

## Procurement Snapshot
- Best fit: Best for asset tagging, packaging, authentication, access control, and smart-label projects.
- Customization: Confirm artwork, encoding, material, chip, and finish requirements before quoting.
- Quote checklist: Confirm mounting surface, adhesive or on-metal requirements, and expected reading distance. Share target chip or protocol, quantity, format or size, print or encoding requirements, and the intended application.

## FAQ
- Q: Is Impinj M750 the same as Monza R6-P?
  A: Yes — Impinj rebranded Monza R6-P silicon as M750 under the M700-series naming refresh (2022). Datasheets, EPC Gen2v2 feature support, sensitivity numbers, and TID prefix are unchanged. Existing readers, encoders, and inlays branded as Monza R6-P fully interoperate with M750 inlays.
- Q: How does M750 differ from M730?
  A: M730 (96-bit EPC, no user memory, no password memory) is the cost-optimised retail volume chip — the Walmart / Inditex mandate default. M750 (96-bit EPC + 32-bit user memory + access / kill password) is the supply-chain / RTI / mixed-application chip — earns its ~30% silicon ASP premium when small on-tag data avoids a cloud round-trip during reading, when RTI cycle counters are written on-tag, or when password-gated writes matter. Same sensitivity floor (~−22.1 vs −22.6 dBm — choose by memory needs, not range). Same antenna designs — chip swap is per-SKU.
- Q: Does M750 support cryptographic AUTHENTICATE or AES-128?
  A: No. The ISO/IEC 18000-63:2015 Amendment 1 AUTHENTICATE command framework exists as an optional standard, but Monza R6-P / M750 does NOT implement it as a shipping feature. This isn't a Monza R6-P-specific gap: per-tap cryptographic chip authentication is not a shipping feature on any mainstream UHF RAIN RFID chip today (Impinj M700 / M800, NXP UCODE 9, Alien Higgs-9). The 'AES-128 crypto AUTHENTICATE' framing that appears in some marketing material describes the standard, not silicon implementations. Programmes that genuinely need per-tap cryptographic authentication (luxury anti-counterfeit, pharmaceutical anti-substitution, banking-grade brand protection) specify HF chips such as NXP NTAG 424 DNA or UCODE DNA — typically deployed alongside, not instead of, a UHF inventory tag.
- Q: What is the short-range mode and is it the same as cryptographic privacy?
  A: Short-range mode is Monza R6-P's physical-layer privacy primitive: the chip can be commanded to reduce its read sensitivity, making it hard for a reader outside the store / warehouse to interrogate the tag. It is a useful privacy mechanism for retail point-of-sale workflows because it doesn't permanently brick the tag (legitimate returns / warranty / re-issue workflows still work). It is NOT cryptographic — it doesn't prove chip identity, doesn't sign messages, doesn't use AES-128. For permanent neutralisation, the EPC Gen2v2 Kill command is available — destructive and one-way.
- Q: Can I use M750 with my existing M730 antenna designs and reader fleet?
  A: Yes — pin- and protocol-compatible. M750 inlays use the same antenna designs as M730 / M770; production lines swap M730 chip-on-foil for M750 chip-on-foil without antenna re-tune, encoder revalidation, or reader-fleet re-qualification. Any EPC Gen2v2-compliant reader (Impinj R700-series, Zebra FX9600 / FX7500, Alien ALR-9900+) reads M750 EPC and writes M750 user memory at standard throughput.
- Q: When should I migrate M750 to M800?
  A: M800 (M830 / M850) delivers ~1-2 dB better sensitivity, ~30% lower chip power, and Gen2X protocol features at a similar silicon ASP to M750. Migrate when sensitivity / power efficiency matter (small-antenna / on-metal / on-liquid programmes) or when Gen2X encoding throughput is operationally significant on high-speed printer-applicator lines. Stay on M750 when 32-bit user memory + short-range mode + the existing ecosystem are working and the sensitivity gain isn't operationally meaningful. The migration is pin- and protocol-compatible — same antenna designs.
