Product Details
AT88SC25616C-MJ - 256-Kbit CryptoMemory Smart Card Module
AT88SC25616C-MJ is a Microchip / Atmel secure CryptoMemory EEPROM with 256 Kbits of user memory divided into sixteen zones. The exact -MJ order code denotes an M2 J ISO-contact smart-card module.
Confirm the complete ordering code, card-contact drawing, and security provisioning for the supplied lot.
Overview
The device provides 32 Kbytes of user EEPROM in sixteen 2-Kbyte zones and a separate 2-Kbit configuration area. Programmable access rights, password and key storage, mutual authentication, encrypted checksums, and stream encryption support controlled nonvolatile storage.
Key Advantages
Sixteen 2-Kbyte zones support separately controlled data areas.
Key sets, passwords, and authentication support device-host policy enforcement.
The -MJ variant is the ISO-capable M2 J module.
Optional anti-tearing helps recover from an interrupted write cycle when implemented correctly.
Feature Summary
Sixteen 16-Kbit user zones; single-byte or 128-byte page writing.
64-bit mutual-authentication protocol, encrypted checksum, stream encryption, and four key sets are documented by Microchip.
The -MJ module supports the documented T=0 and two-wire options, unlike the TWI-only -MJTG variant.
The manufacturer summary specifies 100,000 write cycles and 10-year data retention.
Package & Footprint
The registered form is M2 J, Smart Card Module (ISO). Microchip lists AT88SC25616C-MJ as the M2 J ISO module and -MJTG as the distinct TWI module. The manufacturer summary specifies a 12.6 × 11.4 mm exposed-metal contact area; excised dimensions may be larger. Consult the controlled module drawing for mechanical design.
- Check contact placement and card-body geometry.
- Confirm reader-contact orientation.
- Verify the full -MJ suffix and physical marking.
The local package JPG is absent and the production image URL returns HTTP 404. Keep this draft unpublished until a verified image is supplied.
Interface & Contacts
The manufacturer's ISO module 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 not connected. Check the physical module orientation and do not substitute eight-lead plastic-package numbering.

Replacement Considerations
Other CryptoMemory capacities and the -MJTG two-wire-only module are not automatic replacements. Compare user-zone size, card contacts, ISO T=0 requirements, voltage, temperature, security configuration, and personalization. No unverified internal product link is supplied.
Manufacturer Information
Microchip's AT88SC25616C Summary Datasheet (5017KS–SMEM–08/09) documents memory organization, contact assignments, ordering codes, electrical features, and M2 module dimensions. Use the latest CryptoMemory full specification and manufacturer lifecycle information for final design decisions.
Applications
Store controlled data in an ISO-contact credential.
Allocate zones to separate protected records.
Apply managed keys and access rights during provisioning.
Use two-wire mode only where the exact module and host design support it.
Quality & Authenticity
Inspect module contacts, dimensions, marking, lot traceability, and electrical readout. Control key and password provisioning, zone rights, and write-recovery procedures. Review this mature security architecture against current system threat requirements.
FAQ
Is the configuration area part of user capacity?
No. The 2-Kbit configuration area is separate from the 256-Kbit user EEPROM.
Can -MJTG replace -MJ?
Not unconditionally; -MJTG is the TWI-only module and may not meet ISO T=0 requirements.
Does a plastic package use the same footprint?
No. The M2 J contact module requires its own mechanical drawing.
Can this draft be published now?
No. The registered production package JPG currently returns HTTP 404.
Engineering Notice
Confirm the latest manufacturer-controlled full specification, exact -MJ order code, module dimensions, contact map, operating mode, power conditions, and personalization flow. Verify and deploy the missing JPG before formal publication.
