Details

ST3654 Serial Interface IC supports any RF based modules/transreceiver which is based on Texas Instrument’s Chipcon ICs like CC1100/CC1101(433 Mhz) and CC2500(2.4 Ghz). It provides a simple UART interface for transmission and reception of serial data at various baud rates. It can be used for applications that need two way wireless data transmission. The communication protocol is self controlled and completely transparent to user interface. The IC can be embedded to your current design so that wireless communication can be set up easily.

This IC ST3654 replaces our earlier chip ST1197 with similar functionality but different IC package.

Features

• Automatic switching between TX and RX mode with LED indication
• Adjustable baud rate setting of 9600, 4800, 38400 and 19200
• Frequency Channel can be set to operating multiple pairs in same area
• FSK technology, half duplex mode, robust interference
• Protocol translation is self controlled, easy to use
• High sensitivity, optimized transmission range
• Standard UART interface, TTL(3-5V) logic level with any microcontroller
• Very reliable, small size, easier mounting
• No tuning required, PLL based self tuned
• Error checking(CRC) to prevent corrupted data output at receiver
