Product Details
AT88SC6416C-MJ - 64-Kbit CryptoMemory Smart Card Module
AT88SC6416C-MJ is a Microchip / Atmel CryptoMemory secure EEPROM with 64 Kbits of user memory in sixteen independently controlled zones. The exact -MJ order code identifies an M2 J ISO-contact smart-card module.
Verify the complete order code, contact drawing, and personalization requirements for the supplied lot.
Overview
The 8-Kbyte user EEPROM is organized as sixteen 512-byte zones; a separate 2-Kbit configuration area stores access and security information. Programmable rights, passwords, mutual authentication, encrypted checksums, and stream encryption support controlled storage in contact-card and qualified embedded applications.
Key Advantages
Sixteen user zones allow independent access policies.
Authentication and optional anti-tearing support protected updates.
The -MJ variant is the M2 J ISO module, not the two-wire-only -MJTG option.
The documented ISO T=0 and two-wire operating modes support different system designs.
Feature Summary
64 Kbits divided into sixteen 4-Kbit zones, with single-byte or 128-byte page-write operation.
Four key sets, password options, mutual authentication, encrypted checksums, and stream encryption are documented by Microchip.
The ISO module assigns power, reset, clock, ground, and data to defined C-contacts.
The manufacturer summary specifies 100,000 write cycles and 10-year data retention.
Package & Footprint
The registered package is M2 J, Smart Card Module (ISO). Microchip's ordering table explicitly lists AT88SC6416C-MJ as the M2 J ISO module; AT88SC6416C-MJTG is a different TWI-only module. The manufacturer summary lists a 12.6 × 11.4 mm exposed-metal contact area and notes that excised module dimensions can be larger. Use the controlled drawing for production fit.
- Check the exact contact-area and excised-module dimensions.
- Confirm contact orientation in the card body and reader.
- Match lot marking and full ordering suffix.
The expected local JPG is absent and the production JPG returns HTTP 404. This draft must remain unpublished until a verified image is supplied.
Interface & Contacts
The manufacturer's ISO module contact table assigns C1 to VCC, C2 to RST, C3 to SCL/CLK, C5 to GND, and C7 to SDA/IO. C4, C6, and C8 are shown as not connected. Confirm physical orientation against the controlled M2 drawing; do not transfer plastic-package pin numbers to the module.

Replacement Considerations
Other CryptoMemory densities, plastic packages, and the -MJTG two-wire-only module are not unconditional substitutes. Compare capacity, zone structure, ISO T=0 requirement, contact mapping, temperature grade, personalization, and security policy. No unverified LCDChip product link is asserted.
Manufacturer Information
Microchip's AT88SC6416C Summary Datasheet (5015KS–SMEM–08/09) provides the controlled features, contact table, ordering options, package information, and device organization. Use the current CryptoMemory full specification and manufacturer lifecycle guidance for final design review.
Applications
Store personalized data in a qualified ISO-contact card.
Assign independently managed zones to separate uses.
Apply provisioned access rights to nonvolatile records.
Use documented two-wire operation only after checking the exact module and host protocol.
Quality & Authenticity
Check traceable lot markings, contact finish, dimensions, electrical readout, and programmed access policy. Document provisioning of keys, passwords, zone rights, and recovery behavior. Assess the mature cryptographic mechanisms against current system security requirements.
FAQ
Is all memory user-accessible?
No. The 64-Kbit user EEPROM is separate from the 2-Kbit configuration area.
Is -MJ the same as -MJTG?
No. The ordering table distinguishes the ISO-capable -MJ from the TWI-only -MJTG module.
Can an eight-lead package replace the module?
Not mechanically without redesign; compare contacts and the controlled drawing.
Is this detail ready for publication?
No. Its registered production package JPG currently returns HTTP 404.
Engineering Notice
Verify the latest manufacturer full specification, M2 J module drawing, operating mode, electrical limits, programming sequence, security configuration, and lifecycle before design release. Supply and validate the missing production JPG before formal publication.
