AT88SC0808CA-TH-T

Specialized ICS Overview

The AT88SC0808CA-TH-T is a secure memory IC from the CryptoMemory family, manufactured by Microchip Technology. It provides 8-Kbit (1-Kbyte) of EEPROM user memory organized into eight 128-byte zones. The device operates on a supply voltage of 2.7V to 3.6V and supports a synchronous 2-wire serial interface with a maximum clock frequency of 1 MHz. It features an embedded hardware cryptographic engine for mutual authentication and stream encryption. The component is housed in an 8-TSSOP package with a tape and reel delivery format.

Specialized ICS Feature Summary

• 8-Kbit EEPROM user memory divided into eight individually configurable 128-byte zones
• Embedded 64-bit mutual authentication protocol and stream encryption capabilities
• Synchronous 2-wire serial interface compatible with microcontrollers
• Anti-tearing function and voltage/frequency monitors for data integrity

Specialized ICS Applications

• Embedded system security for sensitive information storage
• Smart card applications using ISO 7816 Class B operation
• Device authentication and access control systems

Specialized ICS Procurement Notes

Verify the specific ordering suffix -TH-T corresponds to the 8-TSSOP package in Tape & Reel format containing 5,000 units per reel. Confirm that the industrial temperature range (-40°C to +85°C) meets the operational requirements. Ensure the source documentation explicitly lists this part number as active or available, as previous variants may have different lifecycle statuses.

Specialized ICS Selection Notes

Select this model when an 8-TSSOP surface-mount package is required for space-constrained designs. The synchronous 2-wire interface is suitable for direct connection to microcontrollers without additional protocol logic. Verify that the 2.7V to 3.6V supply voltage range aligns with the host system's power rails, as it does not support 5V operation in this specific package variant.

Specialized ICS Part Context

This component belongs to the Atmel CryptoMemory family, now managed by Microchip Technology after the acquisition of Atmel. The AT88SC0808CA series offers scalable secure memory solutions ranging from 1-Kbit to 8-Kbits. The -TH-T suffix specifically denotes the Thin Shrink Small Outline Package (TSSOP) delivered in a tape and reel configuration for automated assembly.

Specialized ICS Replacement Considerations

Public confirmed substitute part numbers are not provided in the verified source material. Designers should consult official Microchip documentation for current lifecycle status and potential obsolescence notices regarding the AT88SC0808CA series.
