Microchip Technology, a leading provider of microcontroller and analog semiconductors has released four-member PIC18F4321 8-bit microcontroller family with advanced peripherals, low pin count, small-footprint package options and low power consumption via nanoWatt Technology.

Four-member PIC18F4321 8-bit microcontroller 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 K bytes - to maintain cost-effective pricing.

Microchip Technology's 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. The PIC18F4321 family continues this seamless migration path with a cost-effective and low-power entry point to Microchip Technology's 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 K bytes 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.
