Product Details
AT88SC3216C-SU - 32-Kbit CryptoMemory
AT88SC3216C-SU is a Microchip CryptoMemory secure EEPROM with 32 Kbits of user memory, zone-based access controls and a synchronous two-wire serial interface in an 8-lead SOIC package.
The exact SU ordering code, memory organization and pin assignments are based on Microchip's CryptoMemory Full Specification DS40002661A and AT88SC3216C summary data sheet.
Overview
The AT88SC3216C divides its 32-Kbit user EEPROM into sixteen 256-byte zones. Each zone can be given access rights for application data and security functions. The 8S1 SOIC form uses the synchronous two-wire mode; the smart-card module's asynchronous T=0 mode does not apply to this package.
Key Advantages
Sixteen independently configurable user zones support multiple protected data files.
The embedded security functions can authenticate host and memory device before sensitive operations.
Stream encryption and encrypted-checksum mechanisms support controlled transfers.
The SOIC version communicates over SDA and SCL rather than an asynchronous smart-card interface.
Feature Summary
32 Kbits organized as sixteen 256-byte zones with programmable access rights.
2-Kbit configuration memory and a 37-byte one-time-programmable area.
Four key sets and eight sets of two 24-bit passwords are described for the CryptoMemory family.
The SU suffix denotes the 8S1 SOIC supplied in tubes; SU-T is the separate reel option.
Package & Footprint
Microchip identifies AT88SC3216C-SU as the 8S1, 8-lead 0.150-inch JEDEC SOIC, supplied in tubes. LCDChip's registered package name is 8-SOIC. The separate AT88SC3216C-SU-T code specifies tape and reel; it is not the exact ordering form on this page.
- Use the manufacturer 8S1 land pattern and top-view orientation.
- Route SDA and SCL to the host's compatible two-wire interface.
- Leave all NC terminals unconnected.
The generic photograph illustrates the outline, not device-specific terminal functions.
Pin Functions
The AT88SC3216C summary data sheet gives these SOIC top-view assignments for synchronous two-wire operation.
Do not transfer the RST or smart-card contact pin definitions from module variants to the SOIC.

Replacement Considerations
AT88SC3216C-SU-T differs in shipping media, but any substitution still requires validation of the complete ordering code and manufacturing form. Other CryptoMemory densities can differ in zone count, organization and firmware expectations. No unverified internal alternative link or unconditional drop-in claim is made here.
Manufacturer Information
Atmel introduced the CryptoMemory family; Microchip Technology maintains the documentation. Its AT88SC3216C product page labels the family not recommended for new designs. New platforms should confirm lifecycle and migration choices with Microchip before design commitment.
Applications
Store calibration and configuration values in individually protected zones.
Authenticate replaceable components to a trusted host system.
Partition application data across zones with differing access policies.
Use configured keys and passwords in a controlled authentication workflow.
Quality & Authenticity
Check the full AT88SC3216C-SU ordering code, tube and lot traceability, physical package and provisioned memory configuration. Confirm authentication behavior through an approved host test; package appearance alone cannot establish the intended key state or authenticity.
FAQ
How is the 32-Kbit memory organized?
It is divided into sixteen 256-byte user zones with configurable access rights.
Does the SOIC use the ISO 7816 asynchronous interface?
No. Microchip states that the 8S1 SOIC uses synchronous two-wire mode.
Is SU the reel version?
No. The exact SU code is supplied in tubes; SU-T is the tape-and-reel code.
Can another density replace it directly?
Not without checking zone organization, host commands, keys, access rights and package compatibility.
Engineering Notice
Use the latest Microchip CryptoMemory full specification, AT88SC3216C summary data sheet and controlled 8S1 package drawing before schematic, firmware or PCB approval. Locking security configuration can be irreversible; validate provisioning and recovery procedures before production. This family is marked not recommended for new designs.
