This is a data sheet of PIC16C781/782, which introduces the product's features and characteristics.
The PIC16C781 and PIC16C782 are 8‑bit CMOS microcontrollers featuring an on‑chip RISC CPU, low‑power EPROM, and a rich set of peripherals including ADC, DAC, operational amplifier, comparators, and a programmable switch‑mode controller. They operate up to 20 MHz and support up to 8 mA current at 5 V.
Both devices are offered in 20‑pin packages such as PDIP, SOIC, and SSOP, and include 1 KB (PIC16C781) or 2 KB (PIC16C782) of program memory, 128 bytes of data RAM, 8‑bit timers, and up to eight external ADC channels. The datasheet also details electrical characteristics, pin configurations, and programming options.
