1.0. Introduction The ACM1252U-Z6 is an NFC reader module with an FFC connector
developed based on the 13.56 MHz contactless technology. This NFC
Reader Module supports all three NFC modes, namely card
reader/writer, card emulation, and peer-to-peer communication.
The ACM1252U-Z6 supports ISO 14443 Type A and B cards,
MIFARE®, FeliCa, and ISO 18092–compliant NFC tags. It also
supports other NFC devices with an access speed of up to 424 Kbps
and a proximity operating distance of up to 30 mm (depending on tag
type used).
It is PC/SC-compliant for interoperability across different applications
and platforms, and provides high-speed communication ability for
contactless cards and NFC tags/devices. Post-deployment firmware upgrade is also supported,
eliminating the need for additional hardware modification.

2.0. PIN Assignment
2.1. LED Configuration
There is a bi-color LED (Red and Green) on the ACM1252U-Z6 to display and control its operation
status.
Figure 1: LED Configuration
2.1.1. LED for Power status
The default LED settings when the power is on are Red and Green and then slow flashing Green.
These LEDs cannot be controlled.
2.1.2. LED for smart card operation status
To control the LEDs’ output and checking their behavior for smart card operation status, please refer
to the ACM1252U-Z6 Reference Manual. The manual will discuss how PC/SC APDU commands were
implemented for the contactless interface and device peripherals of the ACM1252U-Z6.
2.1.3. Default LED Behaviors
To control the LEDs’ output and check the LED’s behavior, you may refer to the ACM1252U-Z6
Reference Manual.
