General Information

SM125-M1 is a 28 pin DIP (600 mil, wide) package type module including all neccessary components for 125 KHz RFID Reader/Programmer except for only the antenna/inductor.

SM125-M1 is the same module with SM125-M1-232 but it does not include ST232 IC (RS232 driver chip) on the bottom layer of the PCB.

SM125-IC and the passive components of the the analog front are assembled on the SM125-M1 module PCB, saving time and provides real "ready-to-use" functionality.

SM125-M1 has tremendous features. Unlike any competitors' chip, SM125-IC used on the module, performs all complicated RFID processes such as amplifiying, filtering, demodulating, decoding and digitizing, automatically and make the tag data ready to be sent over UART / I2C / Wiegand 26-bit / Custom defined protocol and can trigger Buzzer/LED/Relay circuit.

SM125-M1 and SM125-M1-232 can be controlled over UART-RS232 /I2C or with its most valuable and unique feature can behave as automated without requiring any external controller.

SM125 chip and module include bootloader and can be upgraded over UART-RS232. For specific applications or requirements, SonMicro is able to modify the firmware and the hardware according to customer needs.

Features

• Single chip including microcontroller, analog circuit and antenna driver results in World's lowest count and smallest RFID reader 

• Available as IC and Module

• Firmware upgrade-able for custom specific applications

• Module requires only antenna and power supply to function, IC requires just few more passive components to function.

• Automatically demodulates and decodes RF signal and make the actual tag data ready. No need to know about complicated RFID subject

• Supports Atmel/Temic T55xx transponders and EM4100/02. (Unique)

• Supports Manchester RF/32 and Manchester RF/64 modulations

• 5V or 3.3V operation ( 3.3V option requires different firmware upgrade)

• Supports hardware and software Sleep Operation

• UART Interface up to 115200bps - I2C Interface up to 400KHz. Module comes with RS232 driver(optional)

• Control-able General Purpose Outputs and Inputs 

• Supports flexible and programmable Wiegand 26 bit output format
