Note 1: Power dissipation is calculated as follows: Pdis = V_DD x {I_DD - I_OH} + {(V_DD-V_OH) x I_OH} + (V_Ol x I_OL)

Note 2: Voltage spikes below V_SS at the MCLR/V_PP pin, inducing currents greater than 80 mA, may cause latch-up.Thus, a series resistor of 50-100W should be used when applying a "low" level to the MCLR/V_PP pin rather than pulling this pin directly to V_SS.

Note 3: PORTD and PORTE not available on the PIC16C63A/73B.

† NOTICE: Stresses above those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress rating only and functional operation of the device at those or any other conditions above those
indicated in the operation listings of this specification is not implied. Exposure to maximum rating conditions for extended periods may affect device reliability.

Description

This PIC16C73B powerful (200 nanosecond instruction execution) yet easy-to-program (only 35 single word instructions) CMOS OTP-based 8-bit microcontroller packs Microchip's powerful PIC? architecture into an 28-pin package and is upwards compatible with the PIC16C5X and PIC12CXXX devices. The PIC16C73B features 5 channels of 8-bit Analog-to-Digital (A/D) converter with 2 additional timers, 2 capture/compare/PWM functions and the synchronous serial port can be configured as either 3-wire Serial Peripheral Interface (SPI?) or the 2-wire Inter-Integrated Circuit (I2C?) bus and a Universal Asynchronous Receiver Transmitter (USART). All of these features make it ideal for more advanced level A/D applications in automotive, industrial, appliances and consumer applications.
