Microchip Technology Adds Lower-Cost Entry Point for PIC18 8-bit Flash MCUs With Advanced Peripherals and Low Power

PIC18F4321 Family Offers Enhanced Flash, 10-bit A/D and nanoWatt Technology in

Low Pin Count 28/40/44-Pin Packages

CHANDLER, Ariz., Sept. 18, 2006 [NASDAQ: MCHP] — Microchip Technology Inc., a leading provider of microcontroller and analog semiconductors, today announced the four-member PIC18F4321 8-bit microcontroller family with advanced peripherals, low pin count, small-footprint package options and low power consumption via nanoWatt Technology. This family offers engineers a more cost-effective entry point to Microchip’s PIC18 high-end 8-bit microcontroller family, with increased performance and peripherals at a lower price—while maintaining a seamless upward migration path to more memory, peripherals and performance.

Many designs require a high-performance 8-bit microcontroller with advanced peripherals, but relatively small memory. The PIC18F4321 provides two serial ports for expanded connectivity, a high-speed 13-channel, 10-bit analog-to-digital (A/D) converter with auto acquisitioning for faster measurements and lower code overhead, and nanoWatt Technology features to reduce power consumption and prolong battery life. Conversely, the PIC18F4321 offers the ideal amount of Enhanced Flash program memory—up to 8 Kbytes—to maintain cost-effective pricing.

“Our broad portfolio of compatible 8-bit microcontrollers allows customers to pinpoint the exact mix of performance and peripherals that will meet their cost and design requirements,” said Mitch Obolsky, vice president of Microchip’s Advanced Microcontroller Architecture Division. “The PIC18F4321 family continues this seamless migration path with a cost-effective and low-power entry point to our most advanced 8-bit microcontroller architecture.”

The PIC18F4321 microcontrollers can be used in a broad range of horizontal applications. Specific examples include: Battery-Powered Devices, Consumer Electronics, Industrial Instrumentation, Communications Control, Automotive and Appliances.

Key features of the PIC18F4321 family include:

• 4 or 8 Kbytes of Flash program memory

• 256 Bytes of EEPROM data memory

• Two Serial Ports (1 synchronous, 1 asynchronous) for USART, I2C™ or SPI communication

• 10-bit A/D x 13 channels at 100 ksps

• 2 analog comparators

• Enhanced capture/compare/pulse-width modulation module with support for MOSFET H-bridges

• nanoWatt Technology low-power modes

• Flexible, low-power internal oscillator, with 32 MHz – 31 kHz operation

Development Tools

The PIC18F4321 family maintains compatibility with Microchip’s free MPLAB® IDE integrated development environment, MPLAB C18 C compiler, MPLAB ICD 2 in-circuit debugger and emulator, and the MPLAB PM3 universal device programmer. In addition, the PICDEM™ 2 Plus (part # DM163022) demonstrates the capabilities of the PIC18F4321 family.

Availability and Pricing

The PIC18F4321/4221/2321/2221 microcontrollers are available now for general sampling at http://sample.microchip.com and volume-production shipments at www.microchipdirect.com.
