Product Details
AT88SC0104CA-MJ — CryptoMemory Secure Memory
AT88SC0104CA-MJ from Microchip Technology is a 1-Kbit CryptoMemory secure memory device with zone-level access control and cryptographic authentication. This exact order uses an M2 J smart-card module supporting ISO 7816 T=0 and synchronous two-wire operation.
Technical and ordering details were checked against the manufacturer's AT88SC0104CA summary datasheet. Use the exact MJ ordering, ISO-module contacts and module drawing for design decisions.
Overview
The AT88SC0104CA provides 128 bytes of user EEPROM organized as four 32-byte zones. Each zone can have separate security access rights, while the on-chip security functions support mutual authentication, message authentication and encrypted data transfer.
Key Advantages
Four independently configurable 32-byte user zones support multiple protected data areas.
Mutual authentication, cryptographic MAC and stream-encryption functions reduce exposure of protected data.
The ISO module supports asynchronous T=0 smart-card communication and synchronous 2-wire operation.
The MJ order uses the manufacturer's M2 J smart-card module with an ISO-module contact arrangement that includes RST.
Feature Summary
1 Kbit / 128 bytes organized as four 256-bit zones.
2-Kbit configuration zone, 37-byte OTP area and 160-byte area for keys and passwords.
Programmable zone access rights, four key sets, password verification and anti-tearing support.
SCL/CLK and SDA/IO provide the serial-clock and bidirectional-data connections.
Package & Footprint
The catalog records M2 J, Smart Card Module (ISO). Microchip lists the exact AT88SC0104CA-MJ order as an M2 J smart-card module supporting ISO T=0 and 2-wire modes. The J module is mechanically distinct from the M2 P logo variant and from packaged IC orders. Confirm the module contact layout and assembly carrier against the manufacturer's controlled drawing.
Module Contact Functions
The manufacturer's ISO module contact map identifies these connections. C2 is RST on this order, unlike the no-connect C2 of TWI-only module orders.

Replacement Considerations
Check memory organization, authentication commands, credential programming, lock state, operating range and physical pinout before considering a different CryptoMemory order code. The UDFN and SOIC variants use different mechanical interfaces; a shared family name does not establish drop-in compatibility. No unverified internal catalog link is provided.
Manufacturer Information
The Microchip/Atmel AT88SC0104CA summary datasheet identifies the exact MJ ordering, M2 J ISO module, contact assignments and electrical ranges. Consult the complete manufacturer documentation and current package drawing before design release.
Applications
Stores protected credentials or configuration data in separately controlled zones.
Supports host-device identity checks in systems designed around its mutual-authentication protocol.
Quality & Authenticity
Verify the complete AT88SC0104CA-MJ code and traceable lot information. For programmed devices, confirm personalization, access rights and lock state against the application specification; electrical identity alone is insufficient to prove functional interchangeability.
FAQ
How much user memory is available?
1 Kbit, organized as four 32-byte user zones.
Which package is used?
The MJ order uses an M2 J smart-card module supporting ISO T=0 and 2-wire modes.
Can a UDFN IC replace this module directly?
No. Mechanical interface, pinout and provisioning must be reviewed.
Is the package picture available?
No. The registered production JPG is missing.
Engineering Notice
Before production, verify the complete manufacturer datasheet, exact M2 J module contact drawing, ISO T=0 and 2-wire timing, power conditions, credential programming and security-zone lock behavior. The production package JPG must be restored and checked before this detail is published.
