Contactless Card Read/Write Module（YW-201）User’s Manual
1Summary
YW-201 contactless card Read/Write module was designed on high
integrated reader ICs for contactless communication on 13.56MHz of
Philips.YW-201 integrates MF RC500 RF base station . Engineers need not
take care how to control MF RC500 RF base station. Just send command to
module over IIC or UART.
YW-200 series contactless card Read/Write module support ISO14443-A
Mifare One S50,S70，UltraLight，MifarePro,ISO14443-B SR176, ISO15693 ,I

☞Communication Protocol:
1. UART: Baud Rate 19200bps。
2. IIC：Max rate 400Kbps。
☞Auto request card: When the card put into antenna, the pin “CARDIN”
will be low.
☞Package: DIP32.
☞Power supply :+4.5~+5.5V.
☞Read Card distance 5~10cm.（Depend on the antenna）
☞You can get C51 source code example with theh module.

5.3 Switch of Uart and IIC
YW-201 Contactless card read/write module support UART and IIC, they can
be switched by the port PORTSEL
PORTSEL = 1(High), UART is selected.
PORTSEL = 0(Low), IIC is selected.
