CHANDLER, Ariz., Aug. 4, 2003 [NASDAQ:  MCHP] — Microchip Technology Inc., a leading provider of microcontroller and analog semiconductors, today announced it has expanded its popular PIC18F family of PICmicro® Flash microcontrollers to include low-cost 48 Kbyte and 64 Kbyte Flash memory devices that offer designers added I/Os, timers, a feature-rich peripheral set and the flexibility of field self-programmability.

Available in 64- and 80-pin TQFP packages, PIC18F8525/6525 and PIC18F8621/6621 16-bit microcontrollers are code-compatible with the Company's current 18-, 28- and 40-pin portfolio, allowing designers to migrate to higher performance devices, and to re-use software and hardware in existing platforms, thus lowering overall development costs and allowing for quicker time-to-market.  These are the newest members of Microchip's 8-bit PICmicro microcontroller family, which recently secured the number one position in worldwide 8-bit microcontroller unit shipments, according to Gartner Dataquest

The microcontrollers feature Microchip's advanced 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.


New Microchip PIC18 Flash Microcontroller Family with 48K & 64Kbytes of Flash
The on-chip Flash has the following features:

  • Entire memory array Erased/Program in less than 2 seconds.
  • Word erase/program time in less than 3 milliseconds.
  • Up to 1,000,000 data memory ERASE/WRITE cycles
  • Up to 100,000 program memory ERASE/WRITE cycles
  • 40 years of data retention.

These new devices feature:

  • Either 48 or 64 Kbytes of Flash memory
  • 4 Kbytes of RAM memory
  • 1024 bytes of high-endurance EEPROM data memory
  • 16-channel 10-bit analog-to-digital converter (ADC)
  • 2 Capture/Compare/PWM modules
  • 3 Enhanced 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) for high-frequency oscillators
  • SPI™
  • I2C™
  • and two LIN compatible addressable USART modules supporting RS485 and RS232.

The cost-effective devices are an ideal solution for a wide range of high-end applications requiring additional memory, in such markets as industrial (TCP/IP controllers, motor control, ballast control), computing (cable modems, POS terminals, voice/fax boards), telecommunications (GPS units), and consumer (MP3 players, security systems, thermostats).

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.

Samples and volume production are available now. For additional information, contact any Microchip.
