Frequently Asked Questions
Q1: What does suffix -LNS+T mean on MAX32555?
A1: L = industrial temperature range; NS = 121-ball CTBGA package; + = lead-free & RoHS compliant; T = tape & reel packing for SMT production.
Q2: How does MAX32555 prevent data theft against physical attacks?
A2: It integrates active anti-tamper loops, voltage/temp fault monitors, clock detection and silicon shielding. It automatically erases all encryption keys once intrusion is detected.
Q3: Why is MAX32555 ideal for payment terminal hardware?
A3: Equipped with Cortex-M3 core, full hardware crypto, on-chip ISO 7816 & magstripe interfaces. It meets PCI-PTS security standards, reduces peripheral components and BOM cost.
Q4: Is external battery required for tamper detection function?
A4: Yes. A tiny coin cell connected to V_BAT pin keeps tamper sensor, RTC and secure backup RAM active even when main power cuts off.
Q5: Are there compatible alternative models if MAX32555 is out of stock?
A5: MAX32558 and MAX32660 are recommended alternatives, with identical payment security architecture and similar peripheral resources.
Q6: Can you provide free engineering samples for testing?
A6: We offer limited free samples for qualified payment equipment manufacturers. Fill in the inquiry form with your project details to apply.
Q7: Does this chip pass global payment security certifications?
A7: The chip is pre-designed to comply with PCI-PTS v6 standards, greatly shortening your terminal certification cycle.
Q8: What development tools can be used to program MAX32555?
A8: It supports standard JTAG debug interface, compatible with Maxim SDK and mainstream ARM Cortex-M development environments.
Q9: What is the typical standby power consumption of the chip?
A9: Ultra-low power standby mode consumes only microamp-level current, extending coin battery service life for tamper detection.
