What this 8-bit PIC brings to a 28-SSOP footprint
The PIC16F72-I/SS: It integrates a 5-channel 8-bit ADC, two I²C/SPI serial interfaces, and on-chip peripherals including brown-out detect, power-on reset, PWM, and watchdog timer.
Memory and peripheral headroom for a cost-sensitive BOM
With 3.5 KB of Flash (2K x 14 words) and 128 bytes of RAM, this part is sized for simple state machines, PWM generation, and serial communication — not data logging or complex protocol stacks. The 22 available I/O pins and 5-channel 8-bit ADC give enough analog and digital interface for a basic sensor hub or motor driver controller. The external oscillator requirement means the board needs a crystal or resonator; there is no internal oscillator on this variant.
Supply voltage and temperature: where it runs
ROHS3 compliance is confirmed, so it passes EU material restrictions without exemption paperwork.
Lifecycle: still in active production
The base product number PIC16F72 is a long-running 8-bit family, so supply through franchised and independent channels is stable.
