MCU Brings Low-Cost Option With 32 Kbytes Of Memory

July 21, 2003

Housed in 64- and 80-pin TQFPs, the PIC18FXX20 flash microcontrollers (MCUs) cram in 32 kbytes of flash memory, 2 kbytes of RAM, and 1 kbyte of EEPROM. Peripherals include an analog-to-digital converter (ADC) with up to 16 channels by 10-bit resolution, five capture/compare/pulse-width-modulation modules, up to 10-MIPS performance at 10 MHz, two 8-bit timers, three 16-bit timers and a watchdog timer (WDT), dual analog comparators, a parallel port, and two addressable USART modules with serial peripheral interface and I²C support. Additional features include a programmable 16-level low-voltage detection module (PLVD), 32-kHz secondary oscillator clock input, and a 4× phase-locked loop (PLL) for high-frequency oscillators. The MPLAB ICD 2 development kit is available for $188.

I earned a Bachelor of Electrical Engineering at the Georgia Institute of Technology and a Masters in Computer Science from Rutgers University. I still do a bit of programming using everything from C and C++ to Rust and Ada/SPARK. I do a bit of PHP programming for Drupal websites. I have posted a few Drupal modules.

I still get a hand on software and electronic hardware. Some of this can be found on our Kit Close-Up video series. You can also see me on many of our TechXchange Talk videos. I am interested in a range of projects from robotics to artificial intelligence.
