Microchip's 8 bit configurable analog microcontrollers are claimed to offer one of the most comprehensive sets of peripherals in the industry. Providing new levels of flexibility and integration with high-performance analog and digital peripherals, the PIC16C781 and PIC16C782 microcontrollers form a complete system-on-chip in a small 20-pin package.
The devices feature a general-purpose operational amplifier, 8 bit digital-to-analog converter, 8 bit analog-to-digital converter, programmable switch mode controller, comparators and a precision voltage reference. A user programmable brown-out detect, programmable low voltage detect, internal oscillator, power saving sleep mode and in-circuit serial programming are also included. The operational amplifier has programmable gain bandwidth product, autocalibration, rail-to-rail output and ultra-low leakage inputs. The two independent high-precision analog comparators feature a low input offset voltage and a programmable output polarity.
The PIC16C781 has 1024 x 14 bits of OTP program memory and the PIC16C782 has 2048 x 14 bits of OTP program memory. Both devices contain 128 bytes of user RAM and can operate at speeds up to 20 MHz. The devices have 16 I/O pins, 4 MHz internal oscillator, one 16 bit timer, one 8 bit timer and a watchdog timer. The PIC16C781 and PIC16C782 are available in 20-pin PDIP, SOIC and SSOP packages.
