SLE 4406SPE M3.2

Application Specific Microcontrollers Overview

The Infineon SLE 4406SPE M3.2 is an intelligent 112-bit EEPROM counter chip designed for prepaid telephone cards and security applications. It features a 16-bit ROM, 104-bit user memory, and a five-stage abacus counter supporting up to 33,352 count units. The device operates at 5 V ± 10% with supply current under 1 mA. It includes advanced security logic, transport code protection, and ISO/IEC 7816 contact configuration. The M3.2 package is a wire-bonded module suitable for embedding in plastic cards.

Application Specific Microcontrollers Feature Summary

• 112-bit EEPROM and 16-bit ROM with 104-bit user memory
• Five-stage abacus counter with up to 33,352 count units
• Advanced security layout with shielded EEPROM cells and logical security functions
• ISO/IEC 7816 compliant synchronous transmission and transport code protection

Application Specific Microcontrollers Applications

• Prepaid telephone cards
• Smart cards requiring secure counting mechanisms
• Security systems with transport code protection requirements

Application Specific Microcontrollers Procurement Notes

Verify the specific ordering suffix (M3) corresponds to the T-M3.2-6 wire-bonded module package. Confirm that the 'E' variant is required for the full 48-bit personalization data capacity in Identification Area 1. Ensure compatibility with existing card embedding processes for this specific module form factor.

Application Specific Microcontrollers Selection Notes

Select the SLE 4406SPE over the SP variant if 48 bits of personalization data are needed in Identification Area 1. The M3.2 package is appropriate for standard plastic card embedding. Verify that the 5 V supply voltage aligns with the target system's power constraints.

Application Specific Microcontrollers Part Context

This component belongs to the SLE 4406 series of intelligent EEPROM counters. It maintains functional compatibility with the legacy SLE 4406S/06SE models while offering enhanced security features through advanced CMOS technology and dedicated shielding.

Application Specific Microcontrollers Replacement Considerations

The SLE 4406SP is functionally compatible but offers only 8 bits of manufacturer data in Identification Area 1 instead of 48 bits. Direct replacement requires verifying if the reduced personalization capacity meets the application's data storage needs.
