We'll tell you all you need to know to start evaluating and working with this product.
Introduced in 1986, Controller Area Network (CAN) technology was originally intended for automotive engine control communication. It has rapidly gained popularity to support a wide range of growing applications, including medical devices, avionics, factory and industrial automation, and maritime environments.
Atmel is well positioned to support CAN networking with a broad portfolio of 8051 microcontroller flash technology, together with extensive experience in CAN networking.
For example, the AT89C51CC01, AT89C51CC02, AT89C51CC03 deliver 5 MIPS at 5V, and 16KBytes to 64KBytes Flash. They can support a wide range of slave applications such as proximity sensor, DeviceNet I/O, textile machine I/O, and many other applications.
For low voltage applications, the following controllers maintain up to 3.3MIPS down to 2.7 volts.
The AT89C51CC02 with 16Kbytes Flash and 0.5Kbytes RAM + a simple 4 message objects CAN engine packaged into a Small Pin Count package is excellent for low end applications where a minimum DeviceNet or CANopen slave stacks are used. It is an ideal low cost product for a CAN controller push-button.
The AT89C51CC01 features 32Kbytes Flash and 1.2 Kbytes RAM, and is well-positioned for slave applications. It offers 2 Kbytes of Boot flash, with at least 3 MIPS remaining for the application on top of a CANopen or DeviceNet stack. The chip features an 8 channel 10 bit A/D converter, 3 timers, a 5-channel high speed input/output timer units, and 32 I/Os. Its 15 message objects and the 1.2Kbytes RAM make the chip suitable for complex I/O systems.
The AT89C51CC03 provides 64Kbytes Flash for application programs and 2Kbytes RAM for a larger object Dictionary. The built-in SPI port also assists communication with other devices. It features 15 message objects as well as 2Kbytes Bootloader and 2Kbytes EEPROM.
