Chandler, Ariz. Microchip Technology Inc. has added 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.
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, two analog comparators and enhanced capture/compare/pulse-width modulation module with support for MOSFET H-bridges. There is also a low-power internal oscillator, with from 32 MHz to 31 kHz operation.
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.
The PIC18F4321/4221/2321/2221 microcontrollers are available now for general sampling at sampling quantities. and volume-production shipments at volume quantities.
The PIC18F4321/4221 come in 44-pin QFN or TQFP and 40-pin PDIP packages, and the PIC18F2321/2221 are available in 28-pin QFN, SOIC, SPDIP and SSOP packages, all of which are RoHS-compliant. Prices start at $2.08 each in 10,000 unit quantities.
