Microchip Technology AT88SC0104C-MPTG

The AT88SC0104C member of the CryptoMemory family combines nonvolatile user storage with access controls, mutual authentication, encrypted checksums, and stream-encrypted communication. Four 32-byte zones can be assigned separate access rules. This MPTG order code identifies the M2 P contact module configured for two-wire operation; it is not the ISO T=0 ordering variant.

The catalog records M2 P, Smart Card Module (TWI), agreeing with the manufacturer's AT88SC0104C-MPTG ordering table. The M2 P exposed contact area is 12.6 × 11.4 mm; the documented square glob top is 8.8 × 8.8 mm, module thickness 0.58 mm, and carrier pitch 14.25 mm. Finished punched module dimensions may be larger than the exposed contact area. This is a contact module, not an 8-lead PDIP.

Layout checks

• Confirm the M2 P square-glob-top style and carrier orientation.
• Align contact positions C1, C3, C5, and C7 with the host reader.
• Leave unused contacts unconnected as specified for the TWI module.
• Check excised module dimensions before mechanical release.

The registered M2-P JPG is absent locally and returns HTTP 404 on the production site; this draft cannot be published until the image is restored and visually verified.

Contact assignments below follow the manufacturer's TWI smart-card-module drawing, not the separate ISO module or 8-lead package drawing.

Do not route C2 as reset on this TWI-only ordering code; C2 is the reset input in the different ISO-module configuration.

Security functions require correct personalization, keys, and access settings. Verify timing, command behavior, and endurance conditions in the controlled datasheet before design release.

The same AT88SC0104C memory is offered in other order-code variants, but M2 J versus M2 P changes module construction and glob-top geometry, while MP versus MPTG changes the documented interface mode. An 8-lead package is not mechanically interchangeable with this contact module. Any candidate requires verification of exact order code, contact layout, host protocol, zone configuration, key provisioning, temperature grade, and mechanical fit. No unverified internal replacement link is supplied.

Microchip Technology hosts the Atmel AT88SC0104C summary datasheet, whose ordering table explicitly lists AT88SC0104C-MPTG as an M2 P two-wire module. The manufacturer document is the authority for electrical and contact details; confirm current lifecycle and controlled revisions before procurement.

Check the complete order code, M2 P square-glob-top format, carrier orientation, contact quality, markings, lot traceability, and controlled material documents. Test the intended two-wire interface and programmed security configuration. A catalog listing alone does not establish provenance, personalization state, or application suitability.

Cryptographic protection depends on correct host implementation, secret management, device personalization, security-fuse programming, and system threat modeling. Use the controlled manufacturer datasheet and full specification for implementation. Publication of this listing is blocked until the correct production M2 P package JPG is accessible and visually confirmed.
