Microchip Technology Introduces New Family of Highly Cost Effective Flash 8-bit PIC® Microcontrollers, Doubles the Performance in Low-Voltage Designs. Ten New PIC18F Microcontrollers Deliver 40 MHz at 3 Volts and 32 to 128 Kbytes of Flash memory in 64- and 80-pin packages.
As the performance levels among 8-, 16- and 32-bit microcontrollers continue to blur and more designs migrate to lower voltages, embedded engineers are looking for cost-effective yet peripheral-rich 8-bit microcontrollers with high memory densities and pincounts that help them preserve their legacy 8-bit code and development-tool investments.
The PIC18F87J10 8-bit microcontroller family addresses these performance and memory needs by providing linear access (no pages) to as much as 128 Kbytes of onboard Flash memory, while offering complete code and tool compatibility with all PIC18F microcontrollers. In addition, the new PIC18F87J10 microcontrollers include nanoWatt Technology for optimal power management 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.
“This new PIC18F family redefines the price-performance ratio for high-pincount and high-density memory 8-bit microcontrollers serving complex embedded applications,” said Mitch Obolsky, vice president of Microchip’s Advanced Microcontroller Architecture Division.
High-end applications that can take advantage of the PIC18F87J10 family’s low operating voltage and high performance levels include: industrial (TCP/IP interface, home-alarm/security-system keypad, server power-supply and temperature controller, power-meter hub, central AC communication controller); consumer (wireless Internet-enabled appliance, hands-free cell phone adapter, cappuccino machine, two-way pager); automotive (car alarm); medical (bio flow meter).
Other key features of the PIC18F87J10 family include:
· 32 to 128 Kbytes of Flash program memory
· Up to 4 Kbytes of data RAM
· Two Enhanced Universal Synchronous/Asynchronous Receiver/Transmitter modules for RS232, RS485 and LIN serial interfaces
· Two Master Synchronous Serial Port modules, each supporting Master I2C or SPI interfaces
· Five Timers/Counters (3 x 16-bit, 2 x 8-bit)
· 15-channel, 10-bit Analog-to-Digital Converter with auto-acquisition timing
· Two Analog Comparators
· Three Enhanced Capture/Compare/PWM modules with support for MOSFET (H-bridge) motor drives
· Two standard Capture/Compare/PWM modules
· Extended Watchdog Timer with prescalar options
· Brownout Reset
· 8-bit/16-bit mode External Memory Access (up to 2 Mbytes)
· Enhanced Instruction Set for improved C Compiler efficiency
Development Tools
The new PIC18F87J10 microcontrollers are supported by Microchip’s world-class development systems, including: MPLAB® Integrated Development Environment (IDE), MPLAB Visual Device Initializer, MPLAB C18 optimizing C Compiler, Application Maestro™ software, MPLAB ICD 2 In-Circuit Debugger and MPLAB PM3 Universal Device Programmer. The PICDEM™ HPC Explorer Board (part # DM183022), is also available to ease development with these high pin-count, large-memory microcontrollers.
