I2C, SPI, 1Wire Interfacing Made Easy
I2C is a simple serial bus for connecting many IC's together
with 2 common wires. I2C makes custom electronics easy and fast. I2CChip
makes I2C easy.
Our I2C2PC Host Adaptor makes it easy to control I2C from a PC or
other controller. Support for I2C, SMBUS, SPI and Dallas 1Wire
gives you a world
of chips to choose from
I2C Slave IC's and Modules, make it easy and fast to
use I2C & SMBus devices to make fast, cheap,
effective equipment.
Thousands of low-cost integrated circuits use serial buses:
A-D's D-A's, LED and LCD Displays, I/O Ports, Radio chips, EEProms,
Temperature Sensors, Relay Drivers, bus expanders, Analog Switches,
Clocks, Counters, Frequency Synthesisers, Clock distribution
amplifiers, MP3 Decoders, Audio IC's.......
Just the Bare IC to build
into your own OEM products. At $3.95 in small quantities, and less in
volume, you can build profitable volume products around the BL233.
3 Serial Buses
5V and 3V compatible buses
All serial buses: I2C, SPI, 1-Wire
Works as simple 8 bit I/O port: Drive LED's and
relays directly
Store POWER-ON, WATCHDOG-TIMEOUT and INTERRUPT macros
internally: Runs even when the PC doesn't.
Works with all Win,Linux, PDA's, Calculators.
Simple ASCII commands: No API's, No DLL's needed. No
hidden software costs.
I2C Bus Connectors and Cables
Free Postage for I2C Bus connector and cable
orders
All our products use the small reliable Micro-match 6
pin connector. For your convenience we have connectors and built up
cables available.
Even if you don't use our adaptors, you can use our
well thought out pinout and, compact connector for I2C and SPI bus
devices.
Free Software: Talk I2C out-of-the-box
Our free Realterm
software talks directly to the I2C-2-PC / BL233. You can just talk
write and read directly from any new serial bus IC with no programming
at all.
Sip Modules: SIP modules as
small, simple pcbs with a single row of I/O pins along one edge, and our
standard I2C connector. The only pins you need to wire up, are the I/O
pins you are using. Everything else is done for you. Because the pins
are 0.1" spaced, they are easy to put on proto-boards of all kinds. You
can even put standard 0.1" plugs on them.
