Product Details
AT88SC0404CA-SH - 4-Kbit CryptoMemory
AT88SC0404CA-SH is a Microchip / Atmel secure two-wire EEPROM with 4 Kbits of user memory arranged as four independently configurable 1-Kbit zones. The exact SH option is an industrial-temperature 8S1 SOIC supplied in bulk tubes.
Technical and ordering details follow the manufacturer's CryptoMemory low-density full specification, Atmel-8664, and AT88SC0404CA summary data sheet.
Overview
The AT88SC0404CA provides access-controlled nonvolatile storage for established security and smart-card applications. Four user zones can have individual access conditions, while the device supports mutual authentication and protected data exchange over a two-wire serial interface.
Key Advantages
Four 128-byte user zones can be protected by individual access rights.
The CryptoMemory command set supports host-device authentication and message authentication codes.
The synchronous serial interface can connect to compatible microcontroller two-wire hardware.
A separate configuration zone stores security settings, keys and passwords.
Feature Summary
4-Kbit user EEPROM divided into four 1-Kbit zones.
Mutual authentication, cryptographic MACs, stream encryption and configurable access rights.
Single-byte and 16-byte page writes, with an anti-tearing function.
SH is the 8S1 SOIC industrial-temperature bulk-tube option.
Package & Footprint
The manufacturer's ordering table lists AT88SC0404CA-SH under the 8S1, 0.150-inch-wide-body JEDEC SOIC package, 100 devices per tube. LCDChip's registered package is 8-SOIC. Use the manufacturer's controlled package drawing and pin-one marker for final footprint approval.
- Confirm the 8S1 package and pin-one orientation.
- Route SCL and SDA for the two-wire interface.
- Review pull-ups, supply decoupling and board-level ESD protection.

Pin Functions
The 8-lead serial package uses these principal connections; check the controlled drawing for exact no-connect handling.
Do not transfer a module or smart-card pinout to this SOIC ordering form.

Replacement Considerations
Other CryptoMemory densities or ordering media are not automatic drop-in substitutes. Compare zone mapping, key configuration, host protocol, package, voltage and lifecycle before substitution. No unverified internal alternative link is asserted.
Manufacturer Information
AT88SC0404CA originated with Atmel and is documented by Microchip Technology in the low-density CryptoMemory full specification and the device summary data sheet. The manufacturer's ordering table distinguishes SH bulk tubes from SH-T tape-and-reel delivery.
Applications
Maintain compatible protected-memory designs.
Store access-controlled credentials or configuration.
Separate application records into independently controlled zones.
Support host-device challenge-response in existing platforms.
Quality & Authenticity
Verify the full SH ordering code, tube and lot labels, SOIC package mark and programmed security state through controlled acceptance testing. Package marking alone does not establish personalization or access-right configuration.
FAQ
How much user memory does this device provide?
It provides 4 Kbits arranged as four 128-byte zones.
What does the SH suffix identify?
It identifies the 8S1 SOIC industrial option supplied in bulk tubes; SH-T is tape and reel.
Is it a plain serial EEPROM?
No. It has security configuration and authentication features in addition to nonvolatile storage.
Can a higher-density family member replace it directly?
Not without checking zone mapping, command behavior and personalization.
Engineering Notice
Use the latest Microchip full specification, device summary, errata and 8S1 package drawing for schematic, firmware, provisioning and production approval. Security depends on correct key handling and host verification; this page does not replace a system-level review.
