MICROCHIP PIC16F819 8-bit Flash Microcontroller, SOIC-18

The MICROCHIP PIC16F819-I/SO is an 8-bit enhanced flash microcontroller featuring advanced nanoWatt power management technology. As part of the mid-range PIC® device family, it offers a robust blend of program memory, data storage, and versatile interfacing capabilities for a wide array of embedded applications. This model is supplied in a compact, surface-mount SOIC package, making it suitable for space-constrained designs.

The microcontroller integrates an 8MHz internal oscillator, 3.5KB of flash program memory, and 256 bytes of EEPROM data memory that boasts impressive data retention of over 40 years and supports up to 100,000 erase/write cycles. For analogue signal processing, it features a 10-bit Analogue-to-Digital Converter (ADC) with five input channels. Its flexible I/O structure provides 16 individually controllable pins, each capable of sinking or sourcing up to 25mA.

Key Features & Interfacing

A significant strength of the PIC16F819 is its rich set of communication peripherals. It includes a synchronous serial port configurable as either a 3-wire SPI™ (Serial Peripheral Interface) or a 2-wire I²C™ (Inter-Integrated Circuit) bus, enabling easy connection to sensors, memories, and other modules. Additionally, it offers a capture/compare/PWM (CCP) module for precise timing and pulse-width modulation tasks.

Development & Debugging Support

Engineers benefit from extensive development support, including In-Circuit Serial Programming™ (ICSP™) and In-Circuit Debugging via just two pins, facilitating easy firmware updates and real-time debugging. The device also supports low-voltage programming and allows the processor read/write access to its own program memory, adding flexibility for advanced application scenarios.

Built for demanding environments, it operates reliably across an industrial temperature range of -40°C to +85°C, with a supply voltage range of 4V to 5.5V. Please note: as
