Product Overview
The MAXQ1103-ENS+ is a 32-bit secure RISC MCU by Analog Devices (Maxim Integrated), tailored for POS, ATM and PIN pad payment terminals. Operating at max 25 MHz, its MAXQ30 core complies with EMV and PCI PTS standards. Equipped with AES/3DES/RSA/DSA crypto accelerators and a hardware TRNG, it adopts DeepCover multi-sensor tamper mesh to block physical intrusions. It carries 512KB secure Flash and 32KB SRAM (1KB battery-backed NV SRAM for immediate key wiping), alongside dual ISO 7816 smart card ports and efficient power management, delivering a complete industrial secure crypto solution.
Core Advantages
Military-Grade Physical Tamper Response
Natively incorporates a continuous active shield monitoring fabric paired with instant, hardware-triggered battery-backed SRAM erasure loops to automatically erase sensitive root keys upon structural component breach detection.
Hardware Cryptographic Engine Acceleration
Houses dedicated execution logic pipelines for asymmetric and symmetric math operations (including RSA up to 2048 bits and deep 3DES/AES transformations), ensuring wire-speed transactions with absolute zero load on the host code layers.
Compliance-Ready Financial Integration
Natively meets international PCI PTS (PIN Transaction Security) and EMV4.3 hardware specifications, massively shortening commercial time-to-market and verification lifecycles for certified payment devices.
Ultra-Low Power Cryptographic Standby
Features sophisticated low-leakage power domains that run the active anti-tamper sensing networks continuously on micro-amperes of coin-cell backup power during terminal storage states.

Frequently Asked Questions
Q1: Is your currently available stock of the MAXQ1103-ENS+ 100% genuine and original?
A: Yes, we guarantee that all MAXQ1103-ENS+ microcontrollers in our warehouse are 100% brand-new, factory-original components directly from Analog Devices / Maxim Integrated. Every batch passes strict incoming verification tracking and is dispatched in factory-sealed TQFP tray configurations to maintain lead coplanarity.
Q2: How does the active tamper detection mechanism inside the MAXQ1103-ENS+ function when the terminal is switched off?
A: The chip includes an ultra-low-power environmental monitoring domain that runs continuously from an external lithium coin cell, even if main power is fully disconnected. If a security violation occurs—such as a case switch opening or trace severance—the internal logic instantly erases the 1KB NV SRAM backup, zeroizing all root cryptographic keys within nanoseconds.
Q3: Does the “+” symbol at the end of the MAXQ1103-ENS+ part number denote a specific feature deviation?
A: The “+” symbol is a standard Maxim Integrated designator specifying Lead-Free (Pb-free) and fully RoHS-compliant material configurations. It ensures the chip is safe for modern eco-compliant automated reflow manufacturing processes.
Q4: How can our physical engineering group get formal component engineering drawings or request bulk wholesale pricing tiers?
A: Please complete the Quick Inquiry form on this webpage with your target quantities. Our application support desk will process your technical and supply criteria and reply with full data assets within 24 hours.
