Product Details
AT88SC12816C-PU - 128-Kbit CryptoMemory Secure EEPROM
Microchip Technology AT88SC12816C-PU is a secure 128-Kbit EEPROM with authentication, encryption and per-zone access control in an 8-lead, 0.300-inch PDIP package.
Technical characteristics and the exact -PU ordering option were checked against the manufacturer's AT88SC12816C summary datasheet.
Overview
The AT88SC12816C belongs to the CryptoMemory family. It provides 16 independently configurable 1-Kbyte user zones and a separate configuration area for access control, keys and passwords. Its synchronous two-wire interface suits embedded hosts; the plastic-package version uses this mode rather than an ISO smart-card module connection.
Key Advantages
Partitioned secure storage
Sixteen 1-Kbyte zones can have distinct access rights for multiple data sets.
Host authentication
Mutual authentication, stream encryption and encrypted checksums support protected host transactions.
Embedded interface
A two-wire serial connection operates at up to 1 MHz under the specified conditions.
Nonvolatile retention
EEPROM architecture is rated for 100,000 endurance cycles and 10 years of data retention.
Feature Summary
Memory organization
128 Kbits of user EEPROM organized as sixteen 8-Kbit zones, plus a 2-Kbit configuration zone.
Access controls
Programmable zone rights, four key sets and password mechanisms support application-specific policies.
Write options
Single-byte and 128-byte page-write modes; optional anti-tearing affects write operation behavior.
Supply range
Specified operation from 2.7 V to 5.5 V across the industrial temperature range for the -PU order code.
Package & Footprint
The exact AT88SC12816C-PU ordering code denotes the manufacturer's 8P3, eight-lead 0.300-inch plastic dual-inline package. The LCDChip package register identifies this footprint as 8-DIP.
- Use the manufacturer's 8P3 mechanical drawing for hole spacing and body dimensions.
- Confirm pin 1 orientation before laying out the socket or board footprint.
- 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 The expected image path is retained; this page must remain unpublished until the image is supplied and verified.
Pin Functions
The manufacturer's SOIC/PDIP pin table assigns the following functions in 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 serial data; use an external pull-up.
No connection in the illustrated plastic-package pinout.
The separate smart-card module has an RST contact; do not transpose that module assignment onto this PDIP option.

Values describe manufacturer-rated characteristics, not measured results for a particular unit. Confirm timing and electrical limits against the complete datasheet at the actual operating point.
Replacement Considerations
Other CryptoMemory densities are not automatic replacements. Compare user-zone organization, personalization, authentication keys, firmware commands and access policy. The -SU option uses an eight-lead SOIC rather than the -PU PDIP footprint; it is not a footprint-compatible substitute. No alternate part is presented as a drop-in replacement or linked without exact product and compatibility verification.
Manufacturer Information
Microchip Technology publishes the AT88SC12816C CryptoMemory documentation and the ordering table identifying the -PU industrial-temperature PDIP option. Verify current lifecycle status and controlled documentation before committing a new design.
Applications
Credential storage
Protected nonvolatile storage for sensitive system or user information.
Embedded authentication
Mutual-authentication transactions between a host and secure memory.
Multi-zone data
Applications requiring separate access policies for multiple records.
Legacy secure-memory maintenance
Service of existing products designed around this exact ordering code and interface.
Quality & Authenticity
Confirm the complete order code, package marking, lead condition and traceability documentation during incoming inspection. Functional verification should include the intended authentication and memory-access flow. Avoid disclosing production keys during test.
FAQ
How much user memory is available?
128 Kbits, arranged in sixteen 1-Kbyte zones.
Can the PDIP version use a two-wire host?
Yes. The plastic-package device uses the synchronous two-wire serial interface.
Is the SOIC order code mechanically interchangeable?
No. The -SU and -PU order codes designate different package footprints.
Does this page confirm a ready-to-use package image?
No. The registered 8-DIP JPG still requires a local asset and visual check.
Engineering Notice
Review the manufacturer's complete specification, package drawing, personalization instructions and current lifecycle information before production use. Security configuration, bus pull-up sizing and host power sequencing are system-design responsibilities. This draft is blocked from publication until its package JPG and rendered page are verified.
