CAN microcontrollers have more memory
Four new 28- and 40/44-pin PIC18F MCUs address the growing need for small, low power, cost-effective microcontrollers with built-in CAN functionality and flexible Flash memory.
Four new 28- and 40/44-pin PIC18F Controller Area Network PIC Flash microcontrollers are designed to address the growing need among automotive and industrial engineers for small, low power, cost-effective microcontrollers with built-in CAN functionality and flexible Flash memory These devices offer Microchip's innovative ECAN module, an easy-to-use, flexible CAN 2.0B interface supporting the Bosch CAN specifications, and providing hardware support for the DeviceNet protocol

Easy interfacing to faster microcontrollers
Microchip has added two new devices to its PIC16C92X family of 8bit one-time-programmable microcontrollers with integrated liquid-crystal display controller.
They also offer up to 64Kbyte of enhanced Flash memory and integrated nanowatt technology low-power modes.
The PIC18F4680, PIC18F2680, PIC18F4585 and PIC18F2585 microcontrollers feature 64 or 48Kbyte of enhanced Flash program memory, which supports self-programming and in-circuit serial programming, allowing the microcontroller to be programmed after assembly, thus providing increased flexibility and manufacturing efficiency, and faster time to market.
Using Microchip's PMOS electrically erasable cell (PEEC) process technology, the enhanced Flash also offers 40 year data retention, and endurance up to 100,000 erase-write cycles, with the data EEPROM specified up to a million erase-write cycles.

Flash microcontrollers run up to 10MIPS
Microchip's new PIC18F010 and PIC18F020 Flash microcontrollers offer an industry-leading performance of 10MIPS, 4Kbyte of program memory, 256byte of user RAM and 64byte of EEPROM.
Additional features of these devices include: an external clock up to 40MHz (10MIPS) a 32kHz to 32MHz (8MIPS) internal oscillator; a fail-safe clock monitor; 3Kbyte of RAM and 1Kbyte of high-endurance EEPROM data memory; a wide voltage range of 2.0-5.5V, and a -40 to +125C temperature range; a 10bit, 100Ksample/s ADC with up to 11 signal channels; two analogue comparators; one capture compare PWM (CCP) module; one enhanced capture compare PWM (ECCP) module; programmable brownout detect and programmable low-voltage detect; and interfaces comprising SPI, I2C and a USART (supporting RS485, RS232 and LIN).
These new cost-effective devices are ideal for a range of high-end CAN applications requiring additional memory.
Examples include: automotive (body control, immobilisers, occupant detection, power steering, anti-lock braking, stability sensing systems); industrial (DeviceNet interfaces, copy machines, hydraulic pressure regulators, motor control); computing (RAID systems, UPSs); consumer (tanning beds, vending machines); and medical (pharmaceutical distribution systems, wheelchairs).
These new microcontrollers are supported by Microchip's high-performance development systems, including the MPLAB integrated development environment, MPLAB C18 C compiler, MPLAB ICD 2 in-circuit debugger and MPLAB ICE 2000 in-circuit emulator.
The PICDEM CAN LIN 2 demonstration board (DM163011) shows the functionality of the CAN module on these devices and is available for $199.
The four new microcontrollers are available today for general sampling and volume production is expected later this quarter.
The PIC18F2680 and PIC18F2585 are housed in 28-pin SDIP and SOIC packages.
The PIC18F4680 and PIC18F4585 come in 40-pin PDIP, and 44-pin TQFP or QFN outlines.
