Product Details
AT88SC0104CA-TH - 1-Kbit CryptoMemory IC
Microchip Technology AT88SC0104CA-TH is a secure serial EEPROM with four user-memory zones, a two-wire interface, and an 8-lead TSSOP package.
Specifications and ordering suffix checked against the manufacturer's AT88SC0104CA summary and low-density CryptoMemory datasheets. Verify the current controlled revision for a new design.
Overview
The AT88SC0104CA belongs to the CryptoMemory family. It combines 1 Kbit of user EEPROM, organized as four 256-bit zones, with configuration memory and security functions for controlled access to stored information. The -TH ordering code identifies the 8X TSSOP package supplied in bulk tubes.
Key Advantages
Segmented storage
Four separately addressed user-memory zones support application data organization.
Controlled access
CryptoMemory authentication and access-control functions support protected read and write workflows.
Simple host connection
A synchronous two-wire interface uses SDA and SCL signals.
Compact footprint
The -TH code uses an 8-lead, 4.4 mm-body TSSOP package.
Feature Summary
Memory
1-Kbit user EEPROM in four 256-bit zones, plus 2-Kbit configuration memory.
Security
Manufacturer-documented authentication, encryption, and access-management mechanisms.
Interface
Two-wire serial communication, with a specified clock rate up to 1 MHz under the applicable operating conditions.
Operating range
2.7 V to 5.5 V supply and -40 °C to +85 °C industrial temperature range.
Package & Footprint
The database registers an 8-TSSOP (0.173 in, 4.40 mm width) package. The manufacturer's -TH ordering entry specifies the 8X, 8-lead TSSOP; its mechanical drawing gives a 4.30-4.50 mm body-width range and 0.65 mm lead pitch. Confirm land pattern against the current 8X drawing.
- Use the manufacturer 8X TSSOP pin map, not the 8S1 SOIC pin map.
- Check body width, 0.65 mm pitch, lead dimensions, and pin-1 orientation.
- Validate assembly and inspection against the current manufacturer drawing.
The package image is pending upload; the listed path currently does not resolve on the production site. The image is illustrative and must not replace the controlled mechanical drawing.
Pin Functions
The manufacturer's 8X TSSOP pin assignment identifies these active connections:
Confirm orientation and unused-pin handling against the current 8X package figure before layout release.

Replacement Considerations
Other AT88SC low-density CryptoMemory members differ in user-memory organization and may also differ in ordering suffix, package, pin assignment, security personalization, and firmware behavior. Do not treat a family member or an 8S1 SOIC option as a drop-in substitute for AT88SC0104CA-TH. Compare the full ordering code, 8X pinout, supply and temperature ratings, command set, security configuration, and footprint before considering a substitution.
No alternative is linked here without a manufacturer-supported equivalence assessment and an exact product match in the LCDChip catalog.
Manufacturer Information
Microchip Technology hosts the Atmel CryptoMemory AT88SC0104CA summary datasheet and the low-density full specification. The summary ordering table explicitly lists AT88SC0104CA-TH as an 8X TSSOP device. Use the latest manufacturer-controlled documentation for programming, security setup, timing, and mechanical details.
Applications
Authenticated accessories
Protected identification and application data in systems that implement the required authentication flow.
Secure configuration
Controlled storage of configuration records, with access rules planned during personalization.
Industrial identification
Small secure data sets in two-wire-connected modules within the specified operating range.
Embedded credentials
Host-managed credential workflows where the CryptoMemory security model has been reviewed for the threat environment.
Quality & Authenticity
Check the full AT88SC0104CA-TH marking, package identity, pin-1 orientation, and traceability information against manufacturer documentation and procurement records. Electrical screening alone does not establish authenticity or the programmed security state. Define incoming-inspection and personalization controls for the end application.
FAQ
What does the -TH suffix specify?
The manufacturer ordering table identifies the 8X, 8-lead TSSOP package in bulk tubes.
Can the SOIC pinout be reused?
No. Consult the 8X TSSOP pin table; its SDA and SCL positions differ from the 8S1 SOIC assignment.
Is the package picture available?
The expected 8-TSSOP JPG path has been reserved, but the production image is not yet available. Use the manufacturer mechanical drawing for design work.
Engineering Notice
This page is a selection aid, not a replacement for the manufacturer datasheets. Confirm exact ordering status, 8X dimensions and pinout, interface timing, supply conditions, programming flow, and security configuration before production. The package JPG is unavailable on this site and must be verified before publication.
