The Mobile Audio Payment Card Reader is a kind of transfer payment tool used for personal transfer payments. It includes an ultra-low-power microcontroller (MCU), payment card slot, Secure Access Module (SAM), Tamper detection and voice interface. The Mobile Audio Payment Card Reader needs to pass both Europay/ Master Card/Visa(EMV) International Organizations standard EMV 2000 and China PBOC3.0 of Level 1 contact certification. Since the Nano100 series has passed EMV 2000 and China PBOC3.0 of Level 1 contact certification and can work at very low power and long standby time and powered by battery, it is very suitable for Mobile Audio Payment Card Reader applications.

The Nano100 series provides high performance and low-cost ultra-low-power 32-bit Arm® Cortex®-M0 core, runs up to 42 MHz, and supports 32-bit hardware multiplier, Low operating voltage 1.8V to 3.6V, Ultra-low power operating mode ( < 200 uA / MHz ), Power-down mode ( RTC, RAM retention < 2.5 uA ), Deep Power-down mode, RAM retention ( < 1 uA ) , Flash ROM up to 128 KB and RAM up to 16 KB, high integrated RTC,  12-bit ADC, 2 MSPS conversion rate, internal RC 12 MHz OSC to reduce system BOM cost, rich peripheral I²Cx2 , SPIx3, UARTx5, ISO7816-3x3, Tamper detection ,Anti-theft lock code bit, 96-bit Unique ID and 128-bit Unique customer ID, and strong anti-jamming ability (ESD 8kV, EFT 4kV).
