CHANDLER, Ariz., May 19, 2003 [NASDAQ:  MCHP] —Microchip Technology Inc., a leading provider of microcontroller and analog semiconductors, today announced that it has expanded its popular PIC18F family of Flash microcontrollers in 64- and 80-pin TQFP packages to include a low-cost 32Kb memory device. Ideally suited for applications requiring a large memory, the large pin-count PICmicro® microcontrollers offer designers added I/Os, timers, a feature-rich peripheral set and the flexibility of field self-programmability. The PIC18F6520 and PIC18F8520 microcontrollers feature Microchip’s PMOS Electrically Erasable Cell (PEEC) process technology, which provides best-in-class erase/write endurance, retention, and disturb reliability for both program and on-chip data EEPROM memory.

The PIC18F6520 and PIC18F8520 microcontrollers are code-compatible with Microchip’s PIC18F452 and PIC18F8720 families of Flash devices, enabling designers to re-use software and hardware in existing platforms, thus lowering overall development costs and time-to-market issues.

By migrating to the new devices, users of Microchip’s PIC18F452 devices retain the large 32Kbyte memory and receive the added benefit of the analog and digital peripherals and connectivity options of the high pin-count devices. Current users of the PIC18F8720 family have the ability to migrate to a smaller memory microcontroller at a lower cost without forfeiting any of the analog or digital features or connectivity options.

Users of Microchip’s one-time programmable (OTP) PIC17C7XX devices have the benefit of being able to migrate to a microcontroller that features the same analog and digital peripherals and connectivity options as the OTP device, but offers the flexibility of a reprogrammable Flash memory device.

The PIC18F6520 and PIC18F8520 feature:

  • 32K bytes of Flash memory
  • 2K bytes RAM
  • 1024 bytes of high endurance EEPROM data memory.
  • analog-to-digital converter (ADC) with up to 16 channels x 10-bit resolution
  • 5 Capture/Compare/PWM modules
  • up to 10 MIPS performance at 10 MHz,
  • two 8-bit timers
  • three 16-bit timers
  • one watch-dog timer (WDT)
  • dual analog comparators
  • parallel slave port (PSP)
  • operating voltage range of 2.0-5.5 volts
  • programmable brown-out detection/reset (PBOR)
  • programmable 16-level Low Voltage Detection module (PLVD)
  • 32 kHz secondary oscillator clock input
  • 4x phase lock loop (PLL)
  • SPI™
  • I2C™
  • two addressable USART modules supporting RS485 and RS232.

The devices offer cost effective solutions for general-purpose applications, such as automotive (instrument cluster panel controller), consumer (washing machine controller interface, furnace controller), industrial (power monitor, industrial motor control) and telecommunications (routers, phone line switching card, fiber optic multiplexer) industries.

Development Tools
Microchip’s PIC18FXX20 TQFP 64- and 80-pin demonstration board shows the functionality of the digital and analog peripherals of the high pin-count PIC18F microcontrollers and complements the MPLAB® In-Circuit Debugger (ICD) 2 tool. The MPLAB ICD 2 development tool is a powerful, low-cost run-time tool that offers cost-effective in-circuit Flash programming and debugging from the graphical user interface of the MPLAB Integrated Development Environment (IDE) tool. This enables a designer to develop and debug source code by watching variables, single-stepping and setting break points. Running at full speed enables testing hardware in real-time.
