Product Details
AT88SC3216C-PU - 32-Kbit CryptoMemory Secure EEPROM
Atmel AT88SC3216C-PU is a 32-Kbit secure EEPROM with per-zone access control and cryptographic authentication in an eight-lead, 0.300-inch PDIP package.
Technical characteristics and the exact -PU ordering option were checked against the manufacturer-hosted AT88SC3216C summary datasheet.
Overview
The AT88SC3216C CryptoMemory device provides 32 Kbits of user EEPROM in sixteen independently configurable 256-byte zones. A separate 2-Kbit configuration zone supports access settings, keys and passwords. The plastic-package version offers a synchronous two-wire interface for embedded host designs.
Key Advantages
Partitioned secure storage
Sixteen 256-byte zones can carry distinct access rights.
Protected transactions
Mutual authentication, stream encryption and encrypted checksums protect host communication.
Embedded interface
The synchronous two-wire bus supports operation up to 1 MHz under specified conditions.
Nonvolatile reliability
EEPROM is rated for 100,000 endurance cycles and 10 years of data retention.
Feature Summary
Memory organization
32 Kbits (4 Kbytes) of user EEPROM in sixteen 256-byte zones, plus a 2-Kbit configuration zone.
Security controls
Programmable zone rights, four authentication and encryption key sets, password mechanisms and anti-tearing support.
Write options
Single-byte or 128-byte page-write modes.
Operating range
The -PU ordering code is specified for 2.7 to 5.5 V and −40 to +85 °C.
Package & Footprint
The exact AT88SC3216C-PU ordering code denotes the manufacturer's 8P3, eight-lead 0.300-inch plastic dual-inline package. The LCDChip package register identifies it as 8-DIP.
- Use the manufacturer's 8P3 drawing for body and lead dimensions.
- Confirm pin 1 orientation before socket or board layout.
- Provide the required SDA pull-up and local supply decoupling.
The registered 8-DIP JPG is not yet present locally. The expected image path is retained; publication requires the image to be supplied and verified.
Pin Functions
The manufacturer SOIC/PDIP pin table assigns these functions to the eight-lead plastic package.
Positive supply, 2.7–5.5 V operating range.
Ground reference.
Serial clock input in two-wire mode.
Bidirectional open-drain data; use an external pull-up.
No connection in the plastic-package pinout.
The smart-card module has an RST contact; do not transpose that assignment to this PDIP device.

These are manufacturer-rated characteristics, not measured results for a particular unit. Check timing and electrical limits at the actual operating point.
Replacement Considerations
Other CryptoMemory densities are not automatic replacements: compare zone organization, security configuration, host commands, key provisioning and access policy. The -SU order code uses an SOIC footprint, not the -PU PDIP footprint. No unverified alternate is presented as a drop-in substitute or linked internally.
Manufacturer Information
Microchip Technology hosts the Atmel AT88SC3216C CryptoMemory summary datasheet. Its ordering table identifies AT88SC3216C-PU as the industrial-temperature 8P3 PDIP option. Verify current controlled documents and lifecycle status before a new design commitment.
Applications
Credential storage
Protected nonvolatile storage for sensitive system or user data.
Embedded authentication
Mutual-authentication transactions between a host and secure memory.
Multi-zone records
Separate access policies for multiple information sets.
Existing secure-memory designs
Maintenance of products already designed for this exact interface and order code.
Quality & Authenticity
Confirm the complete order code, PDIP package marking, lead condition and traceability documentation during incoming inspection. Functional checks should exercise the intended authentication and memory-access flow without disclosing production keys.
FAQ
How much user memory is available?
32 Kbits, arranged in sixteen 256-byte zones.
Can the PDIP version use a two-wire host?
Yes. The plastic-package device uses the synchronous two-wire interface.
Is the SOIC order code footprint-compatible?
No. The -SU and -PU options have different package footprints.
Is the registered package image ready?
No. The 8-DIP JPG still requires a local asset and visual check.
Engineering Notice
Review the manufacturer's full specification, package drawing, personalization guidance and current lifecycle information before production. Security configuration, bus pull-up sizing and power sequencing are system-design responsibilities. This detail is blocked from publication until its package JPG and rendered page are verified.
