3 Product outline

3.1 Outline of ME-MA21 (UART I/F)

The ME-MA21 is used in a reader/writer module for RFID that performs data communication with a

host system using UART I/F (CMOS level I/F), by connecting the device to equipment prepared by

SEGA. Applicable RFID chips are ME-Y2000 series products (1Kbyte/2Kbyte/4Kbyte), which perform

data processing by radio communication with RFID chip incorporated in a card.

The following provides circuit block diagram of the ME-MA21 module:
