This powerful (200 nanosecond instruction execution) yet easy-to-program (only 35 word instructions) CMOS FLASH-based 8-bit microcontroller packs Microchip's powerful PIC® architecture into 28-pin packages and is upwards compatible with the PIC16C5X, PIC12CXXX and PIC16C7X devices. The PIC16F737 features 11 channels of 10-bit Analog-to-Digital (A/D) Converter, 3 timers, 3 Capture/Compare/PWM functions, 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), 2 Comparators, internal RC Oscillator and Advanced Low Power Oscillator controls. All of these features make it ideal for applications including automotive, appliance, battery, RF, motor control and utility metering.
