Microchip Technology, Inc. 8-bit Microcontrollers - MCU PIC17C44-33/PQ

The PIC17C44-33/PQ is a high-performance 8-bit CMOS microcontroller featuring 8KB of EPROM program memory and 454 bytes of data memory. It operates within a voltage range of 2.5V to 6.0V and is designed for low power consumption, with typical currents of less than 5 mA at 5V and 4 MHz, and under 1 mA in standby mode. The microcontroller supports a maximum clock speed of 33 MHz and executes most instructions in a single cycle, with a 121 ns instruction cycle time. Key features include a hardware multiplier, a 16-level deep hardware stack, and various timer/counter options, including an 8-bit timer (TMR2) and a 16-bit timer (TMR3). It also includes a Universal Synchronous Asynchronous Receiver Transmitter (USART) for serial communication. The device has 33 I/O pins with individual direction control, capable of high current sourcing for direct LED drive. Additionally, it offers power-on reset, a watchdog timer, and a power-saving sleep mode, making it suitable for a range of embedded applications.
