Microchip claims its new self-programmable PIC18FXX8 Flash microcontroller family, with intelligent CAN 2.0B active interface, are the smallest most powerful CAN devices available. The new PIC18F248, PIC18F258, PIC18F448 and PIC18F458 devices provide 10 MIPS performance at 10 MHz, in small 28-lead and 40-lead packages.
Microchip says that its PIC18FXX8 microcontrollers offer industry-leading endurance with up to 1 000 000 erase/write cycles to data memory and 100 000 erase/write cycles to program memory. The self-programmable Flash memory allows the device to be programmed in socket via the CAN network, eliminating the need for external high voltage or additional hardware. With an operating range of 2,0-5,5 V, the devices feature up to 32K bytes of Flash program memory, up to 1,5K bytes of user SRAM and 256 bytes of data EEPROM. Advanced features include low voltage programmability and a rich peripheral set, including a 10 bit ADC.
The 40-lead PIC18F448/58 include the Enhanced Capture/Compare/Pulse Width Module (PWM), which is capable of outputting four 10 bit PWM signals with an auto shutdown feature. Additional features include a synchronous serial port supporting 3-wire SPI or a 2-wire I2C, a programmable brown-out detect, programmable low voltage detect, two 10 bit PWMs, 9 bit addressable USART interfaces, five timers, one capture/compare/PWM and an MPLAB In-Circuit Debugger capability.
Microchip's CAN product portfolio includes CAN peripherals and a family of microcontrollers with integrated CAN support. The PIC18CXX8 family of devices feature the company's high-performance PIC18CXXX core with an intelligent CAN interface allowing execution of complex control algorithms and network interfaces on the same microcontroller. Featuring a standalone CAN controller with SPI interface for added design flexibility, the 14-pin MCP2510 brings immediate CAN support to Microchip's entire PICmicro microcontroller line or to any microcontroller architecture with an SPI serial interface.
The devices are available in 28-lead SDIP and SOIC, 40-lead PDIP and 44-lead TQFP and PLCC packages.
