Microcontrollers take more Flash onboard
Four new high pin-count, high-density members of the PIC18F family offer 96 and 128Kbyte of self-reprogrammable, high-endurance Flash memory with up to 10MIPS performance
Microchip Technology has released four new high pin-count, high-density members of the PIC18F family, offering its most cost-effective 96 and 128Kbyte of self-reprogrammable, high-endurance Flash memory with up to 10MIPS performance over a wide operating voltage range of 2.0 to 5.5V. These features, combined with nanoWatt Technology power management and a rich set of analogue and digital peripherals, allow this microcontroller series to compete with 16bit devices in high-end embedded applications while retaining ease of use and helping designers to preserve their 8bit development tool and software investments.

Engineers have a growing need for microcontrollers with increased computational power and larger program memory sizes, due to the transition of code development methodologies from Assembly to C language, and they would rather not discard their 8bit code and development tools.
The PIC18F8722 8bit microcontroller series addresses these performance and memory needs by providing linear access (no pages) to a memory space as large as 2Mbyte, while offering complete code and tool compatibility with smaller Microchip microcontrollers.
In addition, the new PIC18F microcontrollers include nanoWatt Technology for reduced energy budgets and prolonged battery life, along with two synchronous serial ports (capable of SPI or I2C) and two asynchronous serial ports (LIN-capable USARTs) for expanded connectivity.
'Microchip's commitment to offering the greatest breadth of Flash Microcontrollers is exemplified by the PIC18F8722 series, offering the largest memory sizes and richest integrated features for embedded control applications', said Ganesh Moorthy, Vice President of Microchip's Advanced Microcontroller and Memory Division.
'These new products, all of which include our industry-leading nanoWatt Technology, enable design engineers to retain their 8bit code and tools while developing complex embedded applications'.

High-end applications that can take advantage of the PIC18F8722 series' huge linear-memory access space include: industrial (TCP/IP interface, home-alarm/security-system keypad, server power-supply and temperature controller, power-meter hub, warm-water control, central AC communication controller); consumer (wireless Internet-enabled appliance, swing-gate controller, hands-free cellphone adapter, cappuccino machine, two-way pager); automotive (car alarm); and medical (bio flow meter).
Other key features of the PIC18F8722 series include: two enhanced universal synchronous/asynchronous receiver/transmitters for RS232, RS485 and LIN serial interfaces; two master synchronous serial port modules, each supporting master I2C or SPI interfaces; a 16-channel, 10bit analogue-to-digital convertor with auto-acquisition timing; two analogue comparators; enhanced capture/compare/PWM modules with support for MOSFET (H-bridge) motor drives; an extended watchdog timer with prescalar options; programmable brownout reset and low voltage detect circuits; 8bit/16bit mode external memory access; and an enhanced instruction set for improved C Compiler efficiency.
The PICDEM HPCExplorer board, designed to ease development with these high pin-count, high-density devices, is expected to be available in February.
The new PIC18F8722 microcontrollers are also supported by Microchip's world-class development systems, including: MPLAB integrated development environment (IDE), MPLAB C18 C Compiler, MPLAB ICD 2 in-circuit debugger and MPLAB PM3 universal device programmer.
The four new PIC18F8722 series microcontrollers are available now for general sampling and volume production.
